Khawvel pum huapa energy mamawhna a pun zel avangin thermal power plant te hi electric source pawimawh tak pakhat a ni a, an core components te temperature resistance sang tak chu stable operation neih theihna tur kawng pawimawh tak a ni ta a ni. High-temperature components, boiler, steam pipe leh turbines te chu power plant-a an hman ber a nih angin, heat-resistant steel hian power generation efficiency leh equipment life-ah direct impact a nei a, chu chu a hnathawh dan leh material property avang a ni.
Core functions leh hnathawhna hmun Heat-resistant steel .
Heat-resistant steel hi a bulpui ber chu temperature sang, pressure sang leh corrosive environment, boiler superheater, reheater, steam pipe leh turbine blade te tuar thei component te tan hman a ni ber. Thermal power siamna kawngah hian fuel combustion hmanga siam high-temperature flue gas chuan working medium (tui) chu boiler kaltlangin a ti lum a, high-temperature leh high-pressure steam-ah a chantir a, chu chuan turbine chu electric siam turin a khalh a ni.
