Project background

A steam boiler is a piece of vital equipment in the production processes of food industry such as stewing, drying, concentrating and sterilizing. Jiaozuo Yuzhu Instant Noodle Company, affiliated with Henan Province state-run Boai Farm, is a national professional manufacturer of instant noodles with the annual production capacity of over one hundred thousand tons; the instant noodles produced by the company are sold very well all over the country. China is advocating the development of green economy in recent years; Henan Province is vigorously controlling pollution and reforming coal-fired boilers to gas-fired boilers.

As the only state-owned enterprise of instant noodle industry, Jiaozuo Yuzhu Instant Noodle Company actively promoted the "coal to gas" action and ordered one set of 25 tph gas fired boiler (SZS25-1.25-Q) from ZOZEN. The boiler is equipped with a large volume furnace and an advanced imported low NOx burner to effectively reduce the NOx emission. In addition, the boiler adopts the design of membrane water wall; the gastight test must be done before installing thermal insulation layers, to ensure there is no flue gas leak under the condition of micro-positive pressure combustion and help reduce the heat loss of the boiler body; the thermal efficiency will reach up to 98%.
