APH | Boiler | Chemical Engineering

AIR Pre-Heater (APH) preheats combustion air by transferring heat from outgoing flue gas of boiler. GIRAL CFBC boiler consists of a series of long straight tubes of 40 to 65 mm diameter either welded or expanded into the tube plates (perforated) at the both ends. Baffle plates are provided to direct the air over the entire surface of the tubes in cross-flow direction.

Forecasting of Fouling in Air Pre-Heaters Through Deep

Thermal power plants employ regenerative type air pre-heaters (APH) for recovering heat from the boiler flue gases. APH fouling occurs due to deposition of ash particles and products formed by reactions between leaked ammonia from the upstream selective catalytic reduction (SCR) unit and sulphur oxides (SOx) present in the flue gases.

Boiler Efficiency - an overview | ScienceDirect Topics

Boiler efficiency is a measure of how effectively chemical energy in fuel is converted into heat energy in steam going to the turbines. The largest boiler efficiency loss is sensible heat lost as hot flue gases (and ash) exit the boiler. Unburned carbon losses equate to the fraction of combustible fuel which is not burned in the boiler.
