This video is a case collection of ZOZEN's WNS series steam boiler with 10 tph capacity. ZOZEN’s WNS series steam boiler is a kind of horizontal internal combustion wetback boiler and is popular among enterprises in various industries since being launched. This type of boiler adopts wetback structure and is equipped with advanced low NOx burner, which can effectively improve the combustion efficiency and reduce the NOx emission to realize the purpose of energy conservation and environmental protection.
ZOZEN Boiler cooperated with Hebei Yigao Bioenergy Co., Ltd. to improve the reasonable and efficient utilization of biomass energy such as corn straws and so on. According to Hebei Yigao Bioenergy’s requirement of using biomass straws as fuel, ZOZEN Boiler reasonably designed the furnace arch, furnace wall and furnace heating surface of SZL series biomass-fired steam boiler by cooperating with Shanghai Jiaotong University to ensure the combustion efficiency and rated evaporation capacity of boiler.
Shandong Luhua Group Co., Ltd. is a national key leading enterprise of agricultural industrialization in China with 24 production bases and covers industries of edible oil, condiments, vegetable processing and so on. Its annual production capacity of edible oil is 1 million tons and that of condiments is 100,000 tons. ZOZEN's SZS series gas-fired steam boiler and SZS series low NOx gas-fired saturated steam boiler have sufficient heating surface and enough steam and water space to ensure the stability of boiler indexes. Meanwhile, full membrane wall structure can ensure excellent airtightness and thermal efficiency (above 98%). ZOZEN Boiler also adopts ultra low NOx burner via flue gas circulating can ensure the complete combustion of fuel and control the emission of NOx at the same time. It is estimated that boiler's NOx emission is less than 28mg/m3, which completely meets the standards of Environmental Protection Department of Shandong Province.
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.
Recently, ZOZEN took a field trip at the project location of the WNS boiler. The ZOZEN WNS series gas-fired steam boilers are horizontal wetback fire-tube boilers which have reasonable internal structure. An advanced low NOx burner is equipped with the boiler to reduce the NOx emission to less than 30mg/Nm3. At the same time, the burner can realize automatic air adjustment, which can ensure the sufficient fuel combustion.
The YQW series of boiler can realize fully automatic operation, including automatic combustion, automatic adjustment of the liquid level of the expansion tank, outlet temperature, flow rate and automatic protection. Meanwhile, the PLC control system is easy to operate. Various kinds of settings can be completed through the intelligent man-machine interface.
Shandong Minghao Chemical Co., Ltd. specializes in the research and development of C4 deep processing technology and production, mainly include MTBE, isobutylene, polyisobutylene and other products. As one piece of the high-efficiency and energy-saving heating equipment on the production line, the thermal oil heater can achieve precise temperature control and has functions such as over-temperature alarm, low oil level alarm and over-pressure alarm. After numerous inspections and investigations, Minghao Chemical finally chose Wuxi ZOZEN Boilers Co., Ltd. as its equipment supplier.
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.
