ZOZEN Boiler has designed a technical scheme for the project, including 3 sets of SZS series gas-fired superheated steam boilers and 1 set of WNS series gas-fired superheated steam boiler, of which two medium-temperature and medium-pressure SZS series gas-fired superheated steam boilers are used to cooperate with steam turbine for power generation.
ZOZEN WNS series gas-fired steam boiler adopts the large-diameter corrugated furnace and threaded smoke tube to increase the heating surface, reduce the thermal stress and improve the boiler's safety performance; meanwhile, in order to reduce the heat loss caused by gas exhaust and operating costs, ZOZEN also adds energy-saving devices at the end of the flue gas duct to improve the thermal efficiency to over 98%. In addition, the two sets of boilers also meet the ASME standards, which proves that ZOZEN product quality is up to international standards.
ZOZEN develops the convention tube bundles assembly stand which can be turned over at any angle to make the welding worker is always at the appropriate welding angle. It can reduce the welding work difficulty, help the assembling of convention tube bundles and further ensure the quality of welding seams.
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.
In the drum paring working area of ZOZEN Boiler, the steel plates finishing the rolling will accept the circular seam automatic welding here. After the polishing of welding seam, edge milling, chamfering and other pre-welding treatments, the floating rusts on the surface of steel plates are removed to avoid the generation of a large number of air holes in the welding seam, so as to ensure the welding quality.
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.
