Improve Your Boiler's Combustion Efficiency

while producing 45,000 lb/hr of 150 psig steam. Stack gas measurements indicate an excess air level of 44.9% with a flue gas less 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 less combustion air temperature of 300°F. The boiler

side of the boiler where the flue gas temperature is low, fume becomes more significant and thus the deposit chemistry is closer to that of fume. Deposits may react with SO2 and SO3 in the flue gas, converting some carbonate and chloride to sulphate. Figure 7 shows typical compositions of deposits at various locations in the boiler.

Waste Heat Boiler - an overview | ScienceDirect Topics

A flue-gas stack, also known as a smoke stack, chimney stack or simply as a stack, is a type of chimney, a vertical pipe, channel or similar structure through which combustion product gases called flue gases are exhausted to the outside air. 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. Flue gas …

High levels of corrosion resistance allow use with

With forced-draft flues, it is possible by choice of a fan — either forced or induced draft — to overcome system resistance so that the flue will still clear the products. A crude rule-of-thumb is to allow 1 mm 2 of flue area for each 2.2–3.7 kW for natural draft and for 4.5–13.6 kW for each forced draft.
