It was the oracle at Delphi that told Honeywell to build it, “build it and they will buy.” But the oracle was having a bad vision day.
GOOD: The idea of optimum efficiency is a golden fleece. Sobers up everyone in the room instantly. Instinctively, they inch forward in their seats. They’ve heard this odyssey a thousand times, but they still pay very close attention. The Delphi is a marketing muse and withstands the harshest scrutiny — with all her bells and whistles. But that’s where the siren ends. Delphi sinks and we don’t know why. [Read more…]
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.
