2020 Boiler & Pump Training Schedule Released
04 December, 2019

In 2019, RFMCO split its Boiler Operators Workshop class from one class to two separate classes — each focused on the different types of boilers: steam and hydronic. According to students surveyed through the year, the separation allowed individuals to focus on the type of equipment at their facility throughout the entire class whereas in previous years, half the class was spent discussing equipment half the students did not have at their site.


For 2020, RFMCO has added two Hands-On Pump Workshop classes in Las Vegas, NV and San Diego, CA. Pump training in Las Vegas is underserved and pump training in San Diego is highly sought. In addition, each Hands-On Pump Workshop offers CWEA (California Water Environment Association) credits, which helps certified water treatment professionals.

Customized Must Pump Installed to Prevent Harvest Processing Downtime
08 April, 2019

"The Seepex pump along with the quality and speed of the R.F. MacDonald service when the pump requires any type of part or service is truly unsurpassed. When we replacaed our metal lobe pumps with the Seepex our jamming issues were eliminated"


Castoro Cellars began as a small family venture producing a few barrels of wine for family and friends, but over the last two decades has added staff, equipment, facilities and vineyards to blossom into a custom crush operation producing about 60,000 cases of wine per year.

One of the problem areas for the winery processing has been their MUST Pump. MUST consists of the skins, seeds and juice of freshly crushed and destemmed grapes. Sitting below the crusher/ destemmer the MUST pump transfers product to the fementation tanks or presses.

The metal rotary lobe pumps being used by the winery were consistently getting jammed and required the entire line to stop while an operator disassembled, cleared, reset and restarted the pump. After three harvest seasons with these exasperating pumps, Castoro Cellars was seeking a more efficient option.

Seepex Pump below the Delta8 Crusher transferring grape MUST to fermentation tanks


R.F. MacDonald Co. reviewed the problems with the existing MUST pump before designing and developing a customized Seepex Progressive Cavity Pump Model BT1306L. This particular pump contains a metal rotor with a rubber stator that can flex and compress when it encounters solid material that would have jammed the previous equipment. A 40 HP right angle gear motor and a custom made auger helps to continuously convey the solid product into the pump cavity.

The pump also featured a custom-made open hopper to provide an efficient recepticle from a Delta8 Crusher, capable of processing up to 80 tons of material per hour, which is about 320 gallons per minute. On average the winery pumps about 15,000 tons per year through their MUST pump, and has been averaging 3-4 years between stator changeouts.

Fermenting tanks that receive product from the pump


The variable frequency drive is able to adjust the speed of the pump based on the level of the material in the hopper. The pump is automatically controlled but also features a remote speed pot that allows the operator to use a hand-held device to control the speed, stop the pump in emergencies and even reverse the direction to clear any jams downstream. 

An integral dry-run sensor thermal couple was included to detect a temperature increase that would occur at the stator/rotor interface in the event of a dry run condition. The temperature increase triggers the sensor and the pump automatically turns off to prevent any damage to the internals.

The entire pump system was mounted on a wheeled cart so the winery could easily move the assembly to the shop for maintenance and repairs, as well as store the system during off harvest seasons.

Simultaneous Heating and Conditioning Is Achieved with This Unique Boiler
25 May, 2016

Boiler Case Study: Charles Krug Winery - St.Helena, CA 


Customer Applications & Key Challanges 

Charles Krug, Napa Valley's first winery established in 1861, has been owned and operated by the Peter Mondavi family for more than four generations. Charles Krug is recognized as an innovator and pioneer in the winemaking industry, with their exquisite line of critically acclaimed wine vintages being enjoyed by aficionados and casual consumers alike. To assist the fermentation step in the winemaking process, Charles Krug was utilizing a steam boiler to heat their wine to temperatures below 90°F. Unfortunately, the boiler was an older model and relies on a heat exchanger to produce high pressure steam; an unnecessarily expensive and inefficient technology. On top of that, the steam from the boiler was being routed to several different processes throughout the plant. Looking to improve their production process, Charles Krug consulted with R.F. MacDonald Co. to bring the quality of their wine to its fullest potential.


The R.F MacDonald Co. Analysis & Solution

Charles Krug, Napa Valley's first winery, was exploring options to upgrade their boiler and improve their fermentation process, as well as consolidate their boiler and condenser into a single unit. R.F. MacDonald Co. recommended the Cleaver-Brooks Clearfire Model CFC, a boiler system that circulates water through both the boiler and a chiller to achieve any desired temperature, hot or cold. This feature allows Charles Krug to use just one system for both the heating and cooling of their wine tanks, which require different temperatures at various stages throughout the fermentation process.

Charles Krug approved R.F. MacDonald Co.'s recommendation, and the existing boiler was replaced with two Cleaver-Brooks Clearfire boilers. The Clearfire CFC boiler features a combustion system with a pre-mix down firing burner, which is fundamental to achieving efficiencies up to 99% and NOx levels less than 20 ppm. Using natural gas and propane, the Clearfire is suitable for central heating and indirect hot water supply at working pressures up to 3 bar or 5 bar, depending on the required output. A key feature to Charles Krug's application was the Clearfire's capability for simultaneous heating and condensing. Along with the Clearfire, R.F. MacDonald Co. also installed a Camus Boiler for barrel rinsing and domestic water wash downs, which decoupled the boiler from supplying steam to multiple processes at one time.


Project Results

Throughout the installation process, R.F. MacDonald Co. worked in conjunction with the installation crew and provided invaluable expertise and input during the design phase. R.F. MacDonald Co. is now the continuing service provider for the equipment, and proactively monitors and maintains the boiler system at the Charles Krug winery. The boiler system itself is continuing to provide Charles Krug with the freedom to control thermals at the temperature they want, at the time they want. The fuel savings gained from the more efficient boiler, combined with the ease of operation, have culminated into an investment into boiler technology that Charles Krug considers to be a great decision.

The Basic 10 for Boiler Tuning
23 June, 2015

Boiler tuning is necessary to maintain efficiency as well as to ensure reliability and safety. Tuning the burner during the spring and again in the fall is recommended because of the dramatic air temperature and density changes that occur during these seasons.

Both steam and hot water boilers need to be tuned regularly. It is important that a boiler is hot before it is tuned. A cold boiler will throw off the actual operating O2 and CO readings.

Below are the conditions for a natural gas-fired boiler, which is warm, has a load and has a zero pressure reading on the boiler’s steam gauge.

1. Insert the probe into the stack to monitor stack temperature, O2 and CO readings.

2. Power the burner switch, and place the burner in the manual mode and at the low-fire point. The burner will now be under the control of the Burner Management System (Programmer), so expect it to go through its sequence of pre-purging and trial for ignition.

3. With a pressurized boiler, check the O2 analyzer for the O2 and CO readings. If the CO is above 50-100 parts per million, the burner is running rich, and either the fuel needs to be cut back or the air increased. A good excess air at low fire is between 5-8% O2. Also, check the manifold pressure at the burner entrance to make sure it is within the operating parameters as detailed by the manufacturer to assure proper input.

4. Once low-fire is set, manually increase the firing rate incrementally while observing the flame and looking for signs of sooting or instability.

5. At the same time, watch the analyzer at each control point and make cam adjustments (and possibly linkage adjustments) to bring the fuel/air ratio as close to the goal as possible while maintaining safe firing conditions at all times. If the boiler can hold 3% O2 or 15% excess air from medium to high-fire with no more than 50 PPM of CO, the adjustment tuning is excellent.

6. Take into consideration where the boiler fires most of the time. Set the combustion to the maximum efficiency at that particular rate while maintaining a safe margin of excess air.

7. Arriving at high fire, and making the adjustments along the way to the cam/linkages or actuators, check the manifold pressure again to ensure there is full input to the burner as defined by the manufacturer.

8. Manually bring the burner back to low fire, checking the combustion readings as it descends, and make minor tweaks as needed. During this time, watch the linkage movement on a single-point positioning system to ensure there are no hitches or slippage. Confirming this, switch the control from manual to automatic, allowing the burner to modulate on its own.

9. When the burner has reached its stability point with regard to load matching, watch the boiler pressure in relationship to the stack temperature. A well-tuned boiler/ burner package will register a stack temperature between 50-100 degrees above the saturation or water temperature. Anything above this will indicate a dirty boiler or one that has flue gas bypass issues or is badly scaled.

10. Check the safeties, especially the low-water cutoff, the ALWCO and flame scanner. A boiler that is out of tune increases operating expenses as energy exits through the stack. In addition, soot can build up to the point that the tubes overheat and crack or break from their welds, leading to extensive downtime and excessive repair costs.

A Green Solution to Winery Wastewater
18 June, 2014

After the outstanding success of his Napa Valley winery, Robert Mondavi founded the Woodbridge Winery. However, as the expanding market need increased, production also increased and so did the amount of wastewater generated by the plant operations.

Woodbridge Winery was faced with the challenge to meet the production waste stream demands, maintain optimum production at peak efficiency, and meet local and federal regulations, all while adhering to high corporate environmental standards.

The winery wastewater contractor, along with an engineering firm, and hydraulic experts, designed an effective wastewater treatment process. A pump system would collect the maximum output of the plant into a wet well, move the effluent to an equalization tank, through a wastewater reactor, and finally, to aerobic holding ponds. The treated wastewater would be used to irrigate the vineyard, thus providing a "green wastewater process”.

Understand the Power of Burner Management Controls
07 May, 2014

Control PanelToday, most facilities are focused on increasing efficiency and decreasing fuel costs. Many are finding the job easier with a burner management system (BMS) that helps produce reports on a regular basis to monitor processes and detect trends. The power of an advanced burner control system is that it can manage and report on multiple aspects of a boiler control such as; fuel usage and hours of use, stack temperature, lead/lag sequencing, boiler efficiency, and temperature/pressure.       

Automated Safety
A BMS controls every aspect of a burner to ensure proper sequencing and safety. It protects against the malfunction of fuel-firing equipment and reduces possible errors by following the proper operating procedure. The BMS is designed to prevent firing unless a satisfactory furnace purge is completed. It will also delay equipment startup if certain permissive interlocks do not take place. After meeting these criteria, the BMS sequences the burner through its different stages from pre-purge, lighting the pilot flame through the main flame light-off.

Integrating  Multiple Systems
Issues such as high/low main fuel gas pressure or combustion air pressure will sound an alarm. These types of problems will independently appear on the display of an advanced control system’s HMI; however, a standard burner management system does not provide this type of data without additional expanded modules mounted and wired directly on the BMS control.

A boiler operator can install additional flow meters to be monitored with an advanced control system that is not available with a BMS controller alone, thus requiring an additional independent control to monitor and display this information. The advantage of an advanced control system is that it ties all of this equipment into one package and displays it on one screen instead of having multiple devices to accomplish the same thing.

Consider a Hydronic Solution for Boiler Replacement
29 January, 2014

Hydronics at Charles Krug WineryMany winery facilities are replacing their steam boiler with a hydronic one to increase efficiency and decrease operating costs. Before condensing boiler technology was introduced, boilers operated at a maximum of 80 percent to 85 percent efficiency. Today, condensing hydronic boilers can operate at efficiencies up to 99 percent. Hydronic boilers can be used for either building heat or process hot water applications.

Greater Efficiency Equals Reduced Energy Costs
Some facilities that convert from a steam boiler to a condensing one reduce their energy bill by as much as 50 percent. A condensing boiler is more efficient than a steam boiler because it extracts both latent heat and sensible heat from combustion exhaust.
