2017/9/17 · The boiler creates low temperature steam which is not so economical for any power plant. So a super heater is used to heat the steam again. The temperature of the steam is limited at 550 degree centigrade because the turbine material can't sustain temperature above 600 degree centigrade.

Boiler feedwater heaters are designed to improve boiler efficiency by extracting heat from streams such as boiler water blowdown and turbine extraction or excess exhaust steam. Feedwater heaters are generally classified as low-pressure (ahead of the deaerator), high-pressure (after the deaerator), or deaerating heaters.

WNS Horizontal Three Pass Oil or Gas Steam Boilers

WNS gas (oil) fired split steam boiler. This series of boilers is designed with a classic shell type, full-wet back, down-flow and three-pass design structure. The fuel is fully burned in the large-capacity combustion chamber, and the combustion heat load is low, which can greatly reduce the emission of harmful substances such as CO and NOx.
