Project boiler medium：Steam
In the heavy machinery manufacturing industry, the processes of smelting, pouring, and producing finished castings consume a large amount of steam. ZOZEN superheated steam boiler can meet the temperature requirements of these process. Founded in 1958, China National Erzhong Group Co. (CNEG) is one of the national major technical equipment research and development bases. In the purchase of boilers, CNEG had put forward high standards and strict requirements on boiler quality. Through open bidding, ZOZEN sucessfully became the steam boiler supplier for CNEG with its own technical advantages and quality assurance. ZOZEN designed the technical solution of the SZS series gas-fired superheated steam boiler system, which can raise the steam temperature to 300 °C through the superheater.
In addition, the SZS series gas-fired boiler forms a large-volume furnace space by the membrane water wall, which ensures better fuel insulation and full fuel combustion. Combined with advanced the low NOx burner, it can easily achieve low emission of NOx less than 30mg/m³. And in order to further ensure the safe and normal operation of the boiler, boiler will undergo rigorous water pressure test and air tightness test before delivery.
