ZOZEN SZS series condensing gas-fired boilers are typical high-efficiency, energy-saving and environment-friendly boilers with large furnace volume, sufficient radiant heating surface, sufficient fuel combustion and high thermal efficiency of 98%. With advanced combustion equipment, the emission of nitrogen oxides can be less than 30 mg/nm3.
The boiler is additionally provided with an air preheater at the end of the flue gas, and the air is preheated to a certain temperature with the heat carried by the flue gas of the boiler. The heated air enters the combustion room again, which not only accelerates the drying, ignition and combustion processes of the fuel, ensures the stable combustion in the boiler, but also improves the average temperature level in the boiler, thereby strengthening the radiation heat transfer in the boiler and effectively improving the thermal efficiency of the boiler.
Recently, the spot supply of ZOZEN gas-fired boiler solved the urgent problem of the unstable steam supply of biomass gasification boiler during the upgrading and reconstruction of the central heating project. ZOZEN SZS series gas-fired boiler of this tonnage is mainly composed of boiler body, connecting smoke tube, burner, steam-water system, instrument, economizer and condenser. The boiler system has the characteristics of high thermal efficiency, sufficient output, green combustion, pollution-free emission and fully automatic operation.
The YQW series gas/oil-fired thermal oil heater adopts the three-pass round coil whose end adopts the necking coil, which effectively protects the furnace wall at the boiler end. It is equipped with the advanced combustion device and fully automatic operating device. The boiler adopts the packaged structure for delivery, and it can be put into operation only by connecting gas (oil) and electricity after being placed on the project site. With excellent performance and quality, ZOZEN YQW series gas-fired thermal oil heater has won the favor of Jiangsu Guanghui Packaging Materials Co., Ltd.
ZOZEN Boiler provided a set of 46MW SZS series gas-fired hot water boiler for Luanchuan County Thermal Power in Henan Province. The boiler combustion chamber adopts the full membrane wall structure with a large radiation heating surface. There are also energy-saving devices at the end of the boiler, which can reduce the exhaust gas temperature and improve the overall thermal efficiency to 95% and above. In addition, with advanced combustion equipment, the boiler's nitrogen oxide emissions can be less than 30mg/Nm3. ZOZEN SZS series hot water boiler is energy-saving and eco-friendly and has a wide range of capacity, which can meet the demands of central heating in various places.
The ZOZEN 4 tph WNS series gas-fired steam boiler adopts the large-diameter corrugated furnace, which increases the heat transfer surface, reduces the thermal stress and improves the boiler safety. Meanwhile, in order to reduce the heat loss due to exhaust gas and operating costs, ZOZEN also installs the energy-saving equipment at the end of the flue gas duct to ensure boiler's thermal efficiency reaches 98% and above. What's more, WNS series boilers also have the characteristics of fully automatic intelligent control and easy operation to ensure boiler's long-term, safe and stable operation, so they are well received by users at home and abroad.
Interested customers from Hubei province visit ZOZEN Boiler factory for field investigation and deputy general manager introduces the company profile of ZOZEN Boiler and advantages of SZS series gas-fired boiler. Its boiler proper adopts D-model structure. One side is furnace and the other side is convection heating surface. It also adopts membrane wall structure, foreign advanced burner, economizer and condenser at the end of flue gas duct, which can lower the exhaust gas temperature to 60 ℃, enhance the thermal efficiency to 98% and above, and reduce the emission of NOx to less than 30mg/Nm3. This equipment is featured by energy-saving, eco-friendly, safe, highly-efficient and easy to operate and maintain. Its automatic control system can also realize unattended operation.
