The boiler will consume some 5,200 CFM of air and 16,750,000 BTU of fuel (natural gas or light oil). The flue temperature will run at approximately 270 degrees F. This capacity assumes that there is no mineral scaling or other fouling to affect heat transfer on the water side.
Boiler Stainless Steel Exhaust Flue Stack: This is a photo of a boiler stainless steel exhaust stack. It is used for venting corrosive boiler combustion gases. As the flue gases leave the boiler they cool and depending on the dew point of the gas the gas will experience a change of
Flue gas is the gas exiting to the atmosphere via a flue, which is a pipe or channel for conveying exhaust gases from a fireplace, oven, furnace, boiler or steam generator. Quite often, the flue gas refers to the combustion exhaust gas produced at power plants. Its composition depends on what is being burned, but it will usually consist of mostly nitrogen derived from the combustion of air, carbon dioxide, and water

Very few industrial boilers are field erected,” said Aqeel Zaidi, team lead, Industrial/Residential Technology at Enbridge Gas Distribution Inc.
Most commonly, the flue gas passes through the tube side of this air heater design. Ash particles collect loosely on the inside walls of these tubes. In the cold end of a tubular air heater there is the potential for dew point precipitation. This condensate will act as a wetting agent and promote fouling.
