ASTM / ASME Standard Steam Boiler Superheater And Reheater Heating Element


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.

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.



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 Capacity Upgrades to Increase Power Generation


Superheaters are the one of the most important accessories of boiler that improves the thermal efficiency.


In the boiler, the role of superheater is to heat the saturated steam to a certain temperature of superheated steam to increase power plant efficiency. Repeater essentially further improves the thermal power plant cycle efficiency.



Superheater is to increase the temperature of the steam above its saturation point.
Reheater is basically a superheater that superheats steam exiting the high-pressure stage of a turbine. The reheated steam is then sent to the low-pressure stage of the turbine. By reheating steam between high-pressure and low-pressure turbine it is possible to increase the electrical efficiency of the power plant cycle beyond 40%.The reheat cycle is used in large power boilers since it is feasible economically only in larger power plants.

Differences

TypeAdvantagesDisadvantagesSupporting method
Pendant-type1.Firm structural support1. Flow blockage by condensed steam 2. Needs slow restart to purge the water that accumulates in the bottom.supported from above
Inverted-type1.Proper drainage of the condensed steam1. Lack the structural rigidity, especially in high speed gas flowSupported from below
Horizontal -type

1. Proper drainage

2. Good structural rigidity.

1. They do not view the flam directly so they are mainly from the convective typeUsually supported in the vertical gas ducts parallel to the main furnace.


Application


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