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 Boiler is an enterprise specializing in the production of industrial boilers. Its thermal oil heater is divided into YQW series horizontal oil-fired and gas-fired boiler, YQL series vertical oil-fired and gas-fired boiler and YLW series coal-fired boilers. According to different biomass fuels, ZOZEN Boiler has designed different grate widths, lengths and air distribution systems, and the system is combined with different front and rear arch designs, to ensure that different fuels can be burned stably and fully.
An air preheater is used to preheat the fuel which further increases the boiler efficiency. It is designed to heat air before another process by extracting the waste heat from the flue gases leaving the boiler to effectively reduce the flue gas temperature and improve the thermal efficiency.
ZOZEN SZS series gas-fired and oil-fired steam boiler has the advantages of high efficiency and energy saving. This series of boiler adopts double drum with full membrane structure. The SZS series boiler adopts flue gas backflip technology, with the economizer and condenser to improve the thermal efficiency to 98% and above.
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.
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.
This is our ZOZEN brand new WNS steam boiler. It has three basic security precautions. The first, it's a water level gauge. The second, it's a pressure gauge. The third, it's a safety valve. In addition to the three basic security precautions, our ZOZEN uniquely design an extremely low water level protection. These security precautions greatly ensure the safe operation of the boiler.
ZOZEN WNS series oil-fired/gas-fired boiler is a kind of fire tube wetback boiler with a two-pass or three-pass structure. It is equipped with foreign advanced burner, economizer and condenser installed at the end of flue gas duct to lower the exhaust temperature to 60℃, achieve the thermal efficiency of over 98% and control the emission of NOx to less than 30mg/Nm3. It has the characteristics of compact structure, small covering area, short installation period, easy operation and complete automatic control system which can realize unattended operation.
