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.
ZOZEN WNS series gas-fired and oil-fired boiler is equipped with the advanced condenser, which is a kind of flue gas waste heat exchanger whose working principle is the same as the economizer at the end of the coal-fired boiler. After a condenser is installed at the end of the boiler's flue gas duct, the high-temperature flue gas passes through the flue gas duct and the condenser at the same time, which can heat the water in the condenser, increase the feed water temperature and lower the exhaust gas temperature to achieve the goals of saving fuel and improving the thermal efficiency.
A set of industrial boiler with sufficient output and stable heating supply can directly affect the daily production of a food company. ZOZEN DZL series biomass-fired steam boiler adopts the single-drum longitudinal layout and chain grate stratified combustion method. ZOZEN technicians has optimized the design of the feed hopper, grate width and length, speed of grate reducer and position of secondary air outlet by analyzing the different fuel characteristics and practical use requirements of customers to ensure the sufficient combustion of biomass pellets and improve the combustion efficiency. Meanwhile, DZL series biomass fired steam boiler adopts the thread smoke tubes developed by ZOZEN to strengthen the heat transfer and improve the thermal efficiency. The heat transfer coefficient of thread smoke tube is 1.8 times higher than that of ordinary smoke tube and the thermal efficiency of boiler is over 88%, which can fully meet the daily production demands of enterprises.
ZOZEN YQW series horizontal thermal oil heater adopts multi-loop coil structure with good safety performance and sufficient heating surface. Meanwhile, ZOZEN Boiler can also design the waste heat recovery system for users to ensure that boiler's thermal efficiency can reach 95% and above. What's more, automatic control system also ensures the safe and stable operation of thermal oil heater to realize the sustainable high-temperature and low-pressure heating supply. In addition, ZOZEN’s gas-fired thermal oil heater is equipped with advanced low-nitrogen burner to ensure that boiler's NOx emission is lower than 30mg/Nm3 to achieve the excellent performance in environmental protection.
ZOZEN guides and cultivates different kinds of talents according to their different characteristics and laws of growth. In late July, ZOZEN Boiler launched a three-day job training program for new graduates, which was held by the vice general manager and boiler designer, Zhu Qiuping. As a senior boiler engineer, vice general manager Zhu has more than 30 years of experience in boiler design, especially in designing large-scale circulating fluidized bed boiler and gas-fired boiler. He is now the head in charge of ZOZEN Boiler's R&D and design department and is one of the representative persons of ZOZEN Boiler's "soft power".
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.
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.
