The excellent quality of ZOZEN Boiler comes from every working procedure. A convection tube bundle consisting of thousands of tubes is arranged between the upper and lower drums of SZS gas-fired boiler, and each tube should be welded with the drum with high quality to ensure tightness and no leakage. In this part of the work, it requires a large amount of welding with strict requirements, and the welding operation condition is tough. However, the employees of ZOZEN frontline cooperate with each other to ensure the efficient and orderly welding of convection bank tubes.
ZOZEN WNS oil-fired and gas-fired boiler is one of the best-selling series of energy-saving and environmental protection boilers in China. The inside of the boiler consists of large diameter corrugated boiler, threaded smoke tube, and other boiler components.
ZOZEN boiler covers an area of 150 thousand square meters, with an annual production capacity of 2000 industrial boilers and 25000 tons of steam. ZOZEN has built six fully automatic lines for the production of convection pipe, coil pipe, threaded pipe, membrane wall, serpentine tube and header.
ZOZEN Boiler has cooperated with the Department of Thermal Engineering of Shanghai Jiaotong University to jointly develop the DZL series tri-drum biomass-fired boiler. This kind of steam boiler is a water tube boiler adopting the assembled structure with two parts. The boiler can be equipped with different grates to ensure the sufficient combustion of biomass fuels.
ZOZEN DZL series biomass/coal-fired boiler has designed with multiple separate air chambers, which can realize the air distribution at different combustion. With the speed gear, the sufficient combustion of fuel can be ensured according to different combustion rate.
ZOZEN DZL series biomass/coal-fired boiler has sufficient steam output. The boiler adopts the arched tube plates and threaded smoke tubes, which strengthen the heat transfer and solve the cracking problem of rear tube plates. Please kindly click the chat online to get more information.
ZOZEN DZL series boiler can use both biomass and coal as fuel. The dual fuel adaptability would help users to save fuel costs. It adopts three-pass water and fire tube design and can be equipped with economizer and duster cleaner to ensure the combustion efficiency, which can effectively lower the NOx emission.

In 2020, ZOZEN Boiler successfully supplied boilers in Venezuela, Thailand, Afghanistan, Karachi, Zimbabwe and many other countries. Especially in Afghanistan, ZOZEN provided one set of SZL series coal-fired steam boiler for Baheer Group, providing heat source for the paper production line. It successfully passed the environmental protection inspection organized by Afghan government, which had been proved to meet the local environmental protection standards due to the high combustion efficiency and super-clean flue gas emissions.
