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.
The welding of horizontal fixed tubes is to weld the tubes which are put in the horizontal or nearly horizontal position. This kind of welding includes three spacial positions: upright, vertical and horizontal (all-position), which puts forward high requirements for the welding technology. Facing the difficulties brought by welding appearance requirements, curvature of tube joint, and small tube diameter, ZOZEN workers are skilled in welding to ensure the welding quality to effectively extend the service life of boilers.
Affected by the global COVID-19 conditions, many enterprises change their offline business to online business. To solve the problem of communicating with overseas customers, ZOZEN Boiler has purchased a complete set of video conference equipment to keep a smooth communication with overseas customers. Recently, ZOZEN Boiler has organized a video conference with a Korean customer about the circulating fluidized bed boiler project. ZOZEN's general manager Zhang, sales vice general manger Liu, boiler designer Yang and domestic sales manager Wang attended the conference.
ZOZEN Boiler has guided the industrial boiler manufacturing quality for decades. It also has established the technology standards of blanking digitization, automation of welding and assembly moulding to realize the specialized and scale production of boiler's main parts. For further improving the boiler production efficiency and product quality, ZOZEN's Yixing factory introduced a series of new equipment including laser cutting machine, grooving machine, blending machine and sand blasting machine.
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.
Recently, ZOZEN Boiler has organized the training about boiler manufacturing process. This training is given by ZOZEN Boiler's sales manager with the participation of new employees from e-commerce department. They listens carefully and sales manger answers questions for them. The training is relaxing and pleasant, which improves their teamwork ability, deepens their mutual understanding and establishes a friendly and happy working relationship between them.
