In response to increasingly serious environmental problems, Ji Xiang Ju Food decides to purchase low NOx and eco-friendly gas-fired steam boiler. To meet the new requirements, ZOZEN Boiler customizes the boiler system and recommends SZS series low NOx steam boiler to ensure the sufficient heat supply for Ji Xiang Ju Food's production line. This series of gas-fired boiler adopts D-model full membrane wall structure and combustion chamber adopts narrow-spacing tube membrane wall with good air impermeability to reduce heat loss and enhance the thermal efficiency to 98% and above with the economizer at the end of flue gas duct.
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.
Jiangsu Zhongmei Cable mainly produces power cables, fire-retardant cables for coal mines, various flame-retardant and fire-resistant special wires and cables. As we all know, ZOZEN boiler has advanced manufacturing technology and complete equipment, the service life of the boiler is very long. After the inspection at ZOZEN boiler, Jiangsu Zhongmei Cable ordered two sets of 6 tph SZS condensing gas-fired boilers, which can fully improve thermal efficiency.
All equipment (includes boiler proper, economizer, burner, valves, instrument, electric control cabinet, chimney, water treatment, soft water tank, energy-saving circulating pump, raw water pump, deaerator, etc.) is designed to be installed on one or two prepared concrete bases. Skid mounted boiler has all interconnecting piping completed and has passed the cold state test at the factory before delivery. After the boiler arrives at the site, it only needs to be connected to water, electricity and gas to operate.
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%.
