Air Preheaters
An air preheater (APH) is a device designed to heat air before process combustion in a boiler with the primary objective of increasing the thermal efficiency of the process. The purpose of the air preheater is to recover the heat from the boiler flue gas which increases the thermal efficiency of the boiler by reducing the useful heat lost in the flue gas.
Steam Heater
Steam Heaters are heat exchangers in which one of the media is steam being condensed while the other is a process fluid being heated.
Boiler Chimneys
A boiler chimney is a structure for venting hot flue gases or smoke from a boiler to the outside atmosphere. Boiler chimneys are typically vertical, or as near as possible to vertical, to ensure that the gases flow smoothly, drawing air into the combustion in what is known as the stack, or chimney.
