Functions

The functions of superheater as below:

1. The dry saturated steam drum to further make the superheated steam heating. When the soda coexist, the soda heating the mixture, add heat can only be used to make soda water evaporate into steam in the mixture, and cannot make steam temperature of superheated steam. To get to the superheated steam, the commonly used method is to steam separated from the mixture of soda, for its further heating, accomplish this task components become the superheater.

2.reduce the temperature of flue gas, recover the heat in the flue gas, improve boiler efficiency.

Reheater is a kind of steam superheater that reheats the low-pressure steam that has done work and reaches a certain temperature. The role of reheater further improves the thermal efficiency of power plant circulation, and makes the steam temperature of the final stage blade of steam turbine controlled within the allowable range.

1, the role of the reheater, is to do some work in the steam turbine high-pressure cylinder steam, back to the boiler for reheating.Then it is sent back to the middle and low pressure cylinders of the turbine to continue the work.

2. Meet the parameters of reheater installation: in order to improve the cycle efficiency of the unit, only increase the steam pressure and not increase the temperature, will make the steam turbine exhaust humidity is too high, affecting the safety of the steam turbine.Further increase of steam temperature is limited by the high temperature characteristics and cost of steel.Using reheat cycle, the useful enthalpy drop of steam in steam turbine increases, which can further improve the cycle efficiency (primary reheat can improve the cycle efficiency by 4%-6%, secondary reheat can increase by about 2%), in addition, the exhaust humidity can be significantly reduced.
