Air fuel ratio and excess air can improve combustion efficiency of industrial boilers, steam generators, furnaces, ovens, smelters and process heaters. For any combustion process there is a balance sought between losing energy from using too much air, and wasting energy from running too richly. For natural gas fired burners, Get a quote

2007-12-7 · Do you have a frost stat that may be bringing the boiler on during the night? If your room stat is in the hall, 18 degrees may be quite high. Ref your cylinder stat, if it is 3/4 the way down the tank, then at the top it's going to be a hell of a lot higher, so I wouldn't worry too much about bacterial growth. Maybe you're not that much out.

Reduce - The orifice would pass too much water. The blowdown rate would be too great and energy would be wasted. Flashing. The water being drained from the boiler is at saturation temperature, and there is a drop in pressure over the orifice almost equal to the whole boiler pressure.

A boiler system of this type that does not allow outside water sources is a closed system and is highly efficient for using all the condensed water. An open network may be required in operations where the steam or water gets contaminated in such a way that it cannot return to the boiler for reuse.

There may be some loss

Too much pressure means too much water goes into the boiler and that can cause problems. And I'm not talking about flooding problems. The pump controller is on the boiler and it will stop the feed pump from feeding above a certain point, but the sudden inrush of relative cold water will kill the steam that's forming in the boiler for a time.
