Generic Boiler Output Formula? - Boiler and Pressu
Jan 30, 2006· Since combustion equation has 3 moles of gas on both LHS & RHS, for exhaust gas can use (NG + combustion air) volume. Only need to correct for temperature per gas law. Best to use the actual exhaust T, but if not available, use 400 o F. The boiler mfr. recommends the stack ID, so from volumetric flow, you get the exhaust velocity.

Exhaust Gas Boilers also known as Exhaust Gas Economizers, with extended heating surface, used for waste heat recovery in motor ships. A diesel engine loses approximately 30% of the energy to the exhaust gases. A turbocharger recover some of it, but there is still heat losses that can be recovered by means of an Exhaust Gas Boiler, EGB.

Boiler Uptake Fire and Exhaust Gas Economiser Fi
Aug 27, 2015· This may result in boiler soot fire or boiler uptake fire. When an uptake fire is suspected, never soot blow the economiser. Soot blow with steam causes steam to convert as hydrogen gas and result in metal fire. Preventive Actions. Regularly inspect boiler flame to ensure correct air fuel ratio is maintained.
