An air preheater (APH) is a general term used to describe 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.. Hot End Sectorplates are structurally designed with variable stiffness to deform parabolically, when actuated, to match the shape of the deformed operating rotor. Intellectual Property Protection Blast refers to the combustion air being "forced" or supplied above atmospheric pressure.. Specification Heater Preheating temperature Burning rate Flame type temperature-rising speed Preheating time Max. Inside the ducting, the hot furnace gases pass around the preheater tubes, transferring heat from the exhaust gas to the air inside the preheater. Limestone enters via a chute, dropping out of a stone bin onto the brick floor of the preheater. Thereby minimising the hot end leakage gap. / Energy Conversion and Management 114 (2016) 110–121 117 Howden's air preheaters are engineered to meet the demands of your application.
