Air preheater - Wikipedia

An air preheater is any device designed to heat air before another process (for example, combustion in a boiler With the primary objective of increasing the thermal efficiency of the process. They may be used alone or to replace a recuperative heat system or to replace a steam coil.. In particular, this article describes the combustion air preheaters used in large boilers found in thermal

4 furnaces - bureau of energy efficiency

4 FURNACES - Bureau of Energy Efficiency

key to efficient furnace operation lies in complete combustion of fuel with minimum excess air. Furnaces operate with efficiencies as low as 7% as against upto 90% achievable in other combustion equipment such as boiler. This is because of the high temperature at which the furnaces have to operate to meet the required demand.
