Consider Installing a Condensing Economizer

Consider a natural gas-fired boiler that produces 100,000 lb/hr of 100-psig saturated steam. At 83 percent efficiency, the boiler firing rate is about 116 MMBtu/hr. At its full firing rate, the boiler consumes over 4,860 lb of natural gas each hour while exhausting 10,938 lb of high temperature water vapor each hour.

What is a condensing boiler and why are they so …

Kefid · A condensing boiler, on the other hand, recovers the heat from the water vapor and puts it back into the boiler. This allows a condensing boiler to use less fuel to produce the same amount of heat. Same comfort, less fuel, lower bills. Consider the Annual Fuel Utilization Efficiency (AFUE) rating of a boiler, which is a measure of its efficiency.
