The production process of liquid dairy products mainly includes: raw milk acceptance, milk cleaning, refrigeration, preheating, homogenization sterilization, cooling, aseptic filling, fermentation, final product storage etc. Steam boiler is used for fermentation, disinfection, drying, etc., Recently, Wuwei Yili purchased 3 sets of ZOZEN 15tph WNS gas-fired boilers.
The boiler body of WNS series boilers adopts wet-back structure. The combustion, water level, temperature and steam pressure of the boiler are automatically adjusted and protected, which can realize fully automatical operation to ensure safety and reliability. The large-diameter corrugated furnace of this boiler ensures sufficient combustion of natural gas. Combined with an advanced low NOx burner, it can easily achieve the requirement of NOx≤30mg/Nm3. In addition, the boiler is also equipped with energy-saving equipment at the end of the boiler flue, so that the boiler thermal efficiency can reach over 98%.
WNS series horizontal internal combustion boiler is a boiler shell type 3 passes wetback oil/gas fired boiler. After fuel is being atomized by burner, flame is full of the wave furnace and transfer heat via furnace wall, this is 1st pass; the high temperature smoke is collected in reversal chamber and then enters 2nd pass which is grooved tubes bundle area; after heat convection, air temperature gradually falls and goes to front smoke box and turn to 3rd pass, which is smooth tubes bundle area, and then enters chimney passing back smoke box and exhausted to the atmosphere.
The production processes of textiles such as drying, shaping, printing, etc require stable heat source support. WNS series gas-fired steam boilers feature fully automatic and safe operation to ensure the stability of the heat source during the production process. At the same time, the gas-fired boiler has remarkable energy-saving and environmental protection effects, the thermal efficiency can reach over 98%, and the NOx emission can be as low as 30 mg/m³, which fully meets the needs of the environmental protection era.
