steam boilers agency from china, ZOZEN Boiler analyzes the factors affecting the boiler thermal efficiency for you

As a professional boiler manufacturer, ZOZEN Boiler, with the support of policy, has formed a global sales network to cooperate with many overseas enterprises. Its products are exported to Australia, South Africa, Indonesia, Arabia, Thailand and many other areas.

On December 16, the owner and agents made a field visit of the informationalized plant of ZOZEN Boiler, and formally signed a purchasing contract with ZOZEN Boiler on the WNS series gas-fired hot water boilers.

The DHL series coal-fired corner tube boiler is field assembled boiler. It uses a piping system as the frame of the entire boiler, and it bears the full load of the boiler, which makes a non-framework boiler. At the same time, this frame also serves as the down comer of the boiler and upper and lower headers. The boiler drum is an external type drum, the furnace is a fully enclosed membrane wall structure, the convective heating surface adopts the flag tube structure. The corner tube boiler has the advantages of compact structure, low steel consumption and rapid temperature increasing.

The grate bracket of ZOZEN’s chain grate boilers adopts double-layer structure. The lower layer uses channel steel and the upper layer uses light rail. The upper layer is heated and the lower layer is stressed. It changes the traditional grate bracket using angle steel and friction strips without  deformation. The active grate runs on the light rail with a 72-hour cold test run carried out before leaving the factory to ensure the smooth operation of grate without deviation or jamming.

In terms of welding technology, ZOZEN longitudinal and circumferential seam welding adopts advanced automatic submerged arc welding technology, and 100% X-ray detection is carried out on the welding seam to ensure the welding quality. The welding of the smoke tube and tube sheet adopts pre-expansion first to eliminate the gap between the tube and tube sheet, and then adopts the automatic argon arc welding technology, which can effectively eliminate the stress and extend the service life of the boiler.

The complete set of WNS series gas-fired hot water boiler system customized by ZOZEN Boiler for Jilin Mingde Education adopts the corrugated furnace which not only increases the strength and flexibility of the furnace, but also enhances the flue gas disturbance to effectively improve the heat transfer effect. The threaded smoke tube with advanced manufacturing technology has been continuously optimized to effectively absorb the flame energy, and its heat transfer coefficient is 1.2 times higher than that of ordinary smoke tube. At the same time, with the additional finned tube condenser at the end of the flue gas duct, the exhaust gas temperature can be lowered and the boiler thermal efficiency can be as high as over 95%. According to the energy efficiency test conducted by the Thermal Energy Testing Center of the Special Inspection Institute, the performance indicators of the WNS series gas-fired boiler are higher than design requirements and have reached the advanced level at home and abroad, steam boilers agency from china.

steam boilers agency from china, ZOZEN will always adhere to technology research and development, and continue to provide efficient and energy-saving boiler systems for enterprises, further contributing to the high-quality development of the domestic fine chemical industry.
