Replacement products-----Light refr道刀actory fiber castables: Our company s北雪tudies the domestic expanded per制業lite light through the study of t我議he structural flaking o靜外f the gasifier flue lining and th美去e high temperature change aft讀件er the use of the flue metal s黃生tructure. According to the ac河制tual production working condition照她s of the gasifier flue sys熱外tem, the main forms of flu這些e lining damage and the caus鐵車es of damage were analyzed based on the外業 composition and perfor民兒mance of the refractory castable. It co開長mpleted the replacement 要湖product of the expanded perl筆店ite lightweight refract術笑ory castable for the gasifier 身務flue lining - lightwei吧北ght refractory fiber castable. Throu數對gh a large number of practical applic動了ations, the service l通我ife of the flue lining was si拿裡gnificantly extended and the s術些moke was reduced. The maintena男用nce cost of the road improves the produ熱錯ction efficiency of the gas gen車朋erator.
