The excellent quality of ZOZEN Boiler comes from every working procedure. A convection tube bundle consisting of thousands of tubes is arranged between the upper and lower drums of SZS gas-fired boiler, and each tube should be welded with the drum with high quality to ensure tightness and no leakage. In this part of the work, it requires a large amount of welding with strict requirements, and the welding operation condition is tough. However, the employees of ZOZEN frontline cooperate with each other to ensure the efficient and orderly welding of convection bank tubes.
In order to improve employees' awareness of safety in production, ZOZEN Boiler has adopted a safety education system, which is divided into three levels: factory level, workshop level and team level. At the daily team meeting, the team leader takes safety production as an important meeting content to publicize, further clarifies the responsibility for safety production, to improve the safety awareness and sense of responsibility of employees, and to avoid accidents in production. Welding in limited space is a common work environment for ZOZEN workers. Therefore, the frontline workers will dress well with the protection masks and long-sleeve overalls.
ZOZEN Boiler has an advanced membrane wall production line, and the membrane wall tube arrangement is an important working procedure after the membrane wall is put into production. After the membrane wall is welded, it will be made into various shapes by the draw bench machine.
Wood processing is molding the wood under the action of a mould after being softened, bending the curve shape that the design requires, the following procedure is drying and shaping. In this case, wood cannot be heated and shaped by fire, therefore, heating and softening the wood by steam has been the only choice.
The new generation biomass-fired boiler, which is designed and developed by ZOZEN, has optimized the design of the feeding hopper, the length and width of the fire grate, rotary speed of gearbox, 1st and 2nd air ratio, vapor orientation and position, etc; these methods not only take the lead in solving the above problems, but also ensure the full combustion and the thermal efficiency can reach up to 88%; in addition, ZOZEN biomass-fired boiler adopts appropriate heat resisting grate bars, which effectively improve the reliability of the boiler and ensure the stable running of the boiler for a long time.
