4 tph saw dust fired boiler, the seamless welding technology of ZOZEN boiler effectively extends the service life of the boiler

4 tph saw dust fired boiler, After more than 30 years of development, Wuxi Zozen Boilers Co., Ltd. has made outstanding achievements in various industries. Recently, the ZOZEN WNS series gas-fired steam boiler has established a high-temperature sterilization safety line for the production of contact lenses, which has promoted the healthy development of the entire industry.

Recently, data from the National Bureau of Statistics showed that China’s industrial boiler output from January to July in 2020 was 184,780.8 tph, a decrease of 24.8% year-on-year, showing a downward trend. Against the background of a sharp decline in the domestic industrial boiler industry, ZOZEN Boiler managed to overcome the difficulties and achieved a slight increase in output.

ZOZEN YLW series thermal oil heater is of square coil tube vertical type chain grate, it consists of two separate parts - chain grate stoker and heater body. After erection on site, it only needs to connect to thermal oil piping and electricity to start operation. The heater adopts chain grate to perform mechanical fuel feeding, equipped with FD fan and ID fan for air ventilation, and also equipped with slay discharger to remove the bottom slag.

4 tph saw dust fired boiler, In September, ZOZEN SZL series biomass-fired boiler provided for Inner Mongolia Jinshan Mining had been debugged and put into operation smoothly. The boiler has a higher furnace and reasonable grate rotate speed to ensure the sufficient fuel combustion and improve the thermal efficiency to 88% and above. At the same time, the boiler convention area is also equipped with an ash removal device independently developed by ZOZEN which not only has good tightness, but also greatly reduces the workload of the boiler operation and maintenance personnel, so as to help Jinshan Mining achieve clean production and build a green mine.

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.

The key processing technologies of the steel plate of ZOZEN gas fired boiler, such as the slanting of the steel plate, the circle, and the drilling of the drum, all adopt advanced CNC processing technology to reduce assembly stress and extend the service life of the boiler. Process to ensure welding quality, all longitudinal and circumferential welds are 100% radiographically inspected.
