Improve Your Boiler's Combustion Efficiency

2013-5-2 · (MMBtu) of natural gas while producing 45,000 lb/hour of 150-psig steam. Stack gas measurements indicate an excess air level of 44.9% with a flue gas minus combustion air temperature of 400°F. From the table, the boiler combustion efficiency is 78.2% (E1). Tuning the boiler reduces the excess air to 9.5% with a flue gas minus combustion

1. ENERGY PERFORMANCE ASSESSMENT OF BOILERS

2017-9-8 · 1. ENERGY PERFORMANCE ASSESSMENT OF BOILERS Bureau of Energy Efficiency 1 1.1 Introduction Performance of the boiler, like efficiency and evaporation ratio reduces with time, due to poor combustion, heat transfer fouling and poor operation and maintenance. Deterioration of fuel quality and water quality also leads to poor performance of boiler.

boiler flue gas temperature calculation Industrial Gas

Boiler Calculations – KTH. Flue gases are produced when coal, oil, natural gas, wood or any other fuel is combusted in an industrial furnace, a power plant's steam-generating boiler, or other large combustion device. Decreasing the stack temperature by 10ºC corresponds to 0.6% of boiler's efficiency.
