Flue Gas-Air Preheater
Facilities:
"An air preheater (APH) is a General term used for any device that is intended to heat air before another
process (for example, burning in a boiler) with the primary aim being to increase the warm productivity
of the process. They can be used alone or replace a recuperative heat frame or replace a steam loop.
"This article describes in particular the burning air preheater that is used in huge boilers in warm power
plants that supply electricity from, for example, petroleum derivatives, biomass, or waste.
"The motivation behind the air preheater is to recover the heat from the boiler tube gas, which
increases the warm productivity of the heater by losing the helpful heat in the tube gas. As a result, the
tube gases are sent to the tube gas stack (or smoke stack) even at a lower temperature, so that the Plan
of the line and the vent gas stack can be rearranged. It also allows control over the temperature of gases
leaving the stack.
"Type: Tube-Type Regenerative Air Preheater The Rotating-Plate Regenerative Air Preheater Is
Stationary-Plate Regenerative Air Preheater
Applications:
"These kind of air Preheaters are a bit easier in their design. They often seem to be large and boxy and
can take up a lot of space compared to the Rotary Air preheating.
Advantage:
"Air preheaters replace hot air from Gas to air by a rotating grille where warm is consumed by the
warming components that pass through the hot gas stream and are replaced into the ignition air stream.
