Air preheater product description

The function of Super heater in the thermal power plant is to remove the last traces of moisture from the saturated steam coming out of boiler and to increase its temperature above saturation temperature as per requirement at inlet of steam turbine.

Air preheater details

Superheating raises overall efficiency as well as avoids too much condensation in last stages of turbine which avoids blade erosion.

The heat of combustion gases from furnace is utilised for removal of moisture from steam and to superheat the steam.

Super-heaters ususlly have several tube circuits in parallel with one or more return bends,connected between headers.

Heat from the hot gases to the vapour in the surperheater is transferred at high temperatures.

Therefore promary section of superheater is arranged in counterflow and secondary section in parallel flow to reduce the temp.stressing of the tube wall.

Air preheater principle

Principle of superheater is similar to steam generating tubes of boiler.

The hot gases at high temperature sweep over superheater tubes and raise the temperature of steam which magnitude depends upon exit gas temperature leaving the superheater and gas velocity.

use for heating saturated steam, steam temperature could be up to 900 degree C.

Superheater/air preheater capacity upgrades to increase power generation

Send us required technical data, such as steam capacity, presure, required temperature etc. We will design accordingly.
