ZOZEN 15 tph SZS series steam boiler is widely applied in the printing and dyeing, nonferrous metals, chemical and other industries. The SZS series boiler is designed with longitudinal double drums and "D " type chamber structure. Furnace is placed on the right and convection tube bank is on the left, super heater is arranged at convection tube bank. Smoke from furnace outlet enters re-burning chamber, convection tube bank area and then from left front part enters spiral fine coil economizer and condenser, and finally is discharged to atmosphere through chimney.
ZOZEN 10 tph SZL series steam boiler is widely applied in the nonferrous metals, pharmaceutical, printing and dyeing and other industries. The SZL series coal-fired/biomass-fired steam boiler is packaged or shop-assembled boiler with double drums and a chain grate stoker structure. The 4-6 tph boiler is a packaged structure and the 6-35 tph boiler is a shop-assembled structure. It is composed of 2 parts. The upper part is heat absorbing surface and the lower part is combustion equipment.
YQW series thermal oil heater adopts three-pass round coil structure with larger inner coil design to ensure boiler's safe operation under high temperature. It is also equipped with advanced burner and control system. They realize the automatic and stable operation of thermal oil heater. There is waste heat recovery device as well to improve the thermal efficiency to 95% and above.
DZL series hot water boiler is horizontal three-pass water-fire tube chain grate boiler. It uses fuel like coal and biomass pellets. The thread smoke tubes inside the drum form the convention heating surface while the drum and two-side water-cooled wall form the furnace radiation heating surface. Its boiler structure is compact. It can be packaged before shipment which can reduce the costs of basic boiler construction. Therefore, it is a kind of popular heating equipment among hotels, schools and hospitals.
This is the modern production base of Wuzi ZOZEN Boilers Co., Ltd with 12 workshops and more than 150,000 square meters overall floorage. ZOZEN possesses digitized and automatic boiler production lines that can produce four series of products: gas-fired or oil-fired boiler, coal-fired boiler, biomass-fired boiler and thermal oil heater. Welcome you to visit ZOZEN.
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.
