I have been asked over the years “What is a boiler horsepower” and what is the design criterion of square feet of heating surface per boiler horsepower.
We have written many articles about flame safe guard controls on Control Trends but we have not really given an explanation on the basic principles of these controls.
Stromquist and Company does not sell fire tube boilers but we do sell a vast amount of controls for these boilers from manufactures such as Conbraco, Honeywell, Asco, McDonnell & Miller, Maxitrol, and numerous other control manufacturers. The understanding of these boilers is a major concern in our continuing efforts to keep our readers informed.
FIRE TUBE BOILERS:
In a fire tube steam boiler, heat and gases of combustion pass through the tube surrounded by water. Fire tube boilers steam boilers maybe either high or low pressure boilers. The three types of fire tube steam boilers are horizontal return tubular boiler, scotch marine boiler, and vertical fire tube boiler.
Proper boiler blowdown is an essential part of firetube boiler operating proceedures. It is necessary to control the amount of TDS (total dissolved solids) in the boiler water.The total TDS should not exceed 3500 parts per million in a scotch marine boiler. If the blowdown is not controlled, excessive dissolved solids will have a tendency to increase and concentrate to a point that will cause a foaming or a carry over condition which will contaminate the steam.
We caught up with Testo’s Jim Burke at the CGNA Vendor showcase. Jim showed us some of the cool new instruments and meters that Testo brought to the HVAC market place. In this short video you can see Read More
Fault codes are used on the Honeywell RM7800 series of boiler burner flame safeguard controls. These codes help the service technician identify problems that occur with the relay or the components that are wired to the relay.
Bacharach has been a leader in combustion analyzers and test instruments for over one hundred years. Check out this video on how to use the Bacharach Fyrite Insight combustion analyzer. Read More
Honeywell has announced they are introducing a series of integrated combustion panels to go along with the awsome Delphi release from last year. These new panels will incorporate Honeywell’s proven combustion technology into complete panels, making equipment upgrades a snap! All panels will be pre-wired, pre-tested, and a built in a certified UL panel shop. Made in the U.S.A.
The initial offering will include: Read More

Need to replace the older M series Fireye controls? Honeywell has introduced the Honeywell ECHO retrofit solution for replacing the Fireye TFM and UVM FSG controls. The ECHO (R7210M series) controls are a Smart Fit series of controls which allow the contractor to replace the older Fireye M series controls without the extensive wiring required in the past.
The Honeywell ECHO system is based on the standard Honeywell 7800 series controls and all of the standard 7800 series components will work with this control. With the Honeywell ECHO you can now expand the functions that were limited on the Fireye M Series controls to include displays that improve diagnostics and troubleshooting and including the addition of Modbus to connect the equipment to a building automation system.
How easy is the Honeywell ECHO system to install? Simply remove the old Fireye M series control, attach the Echo’s metal conversion frame, and plug in the ECHO control… Add the required purge timing card (if needed), the flame amplifier , and the Flame detector for UV systems…It’s that easy…
While your at it sign up for the Stromquist & Company Boiler Vision Program and save even more !!
So when you need to replace an older Fireye M series control give us a call here at Stromquist and Company and listen to the ECHO….
