Boiler header is a kind of large-diameter pipe connecting several heating surface pipes. It is made of seamless steel pipes with welding heads at both ends, and there are many pipe holes on the header body for welding or expanding pipes. The boiler header collects or distributes the steam-water working medium, to reduce the transmission connecting pipes of working medium and the number of tappings in the drum, which can improve the safety of the drum.
Membrane wall refers to the water wall composed of airtight tube screen welded by flat steel and pipes. Membrane wall can ensure that the furnace has good air tightness, which can significantly reduce the air leakage coefficient of the furnace and improve the combustion conditions in the furnace for negative pressure boilers.
The customer is mainly responsible for the central heating and operation of natural gas in Fanxian New District, and the heating area covers 39 old local communities. The heating boiler selected by the company is ZOZEN SZS gas-fired hot water boiler, which has the characteristics of energy saving, environmental protection and automatic operation, and provides comfortable heating experience for local residents.
ZOZEN SZS series gas-fired boiler adopts the D-type chamber structure, the large furnace ensures the sufficient combustion and radiation heating area. The thermal efficiency of the boiler can reach up to 98%. Also, the reasonable arrangement of steam and water separator effectively reduces the water content of the steam.
According to the different performance parameters, ZOZEN SZS series gas-fired boilers can be divided into self-contained, assembled and shipped in bulk. ZOZEN SZS series double drum vertical gas-fired watertube boiler is a typical medium and large-sized gas-fired boiler, with a capacity of 20-110t/h and a pressure of 1.25-5.3MPa, which meets the needs of steam and heating for most enterprises. The SZS gas-fired boiler shipped to Hebei this time was delivered in bulk, and the photos show the drum, an important pressure-bearing component of the boiler, which plays the role of steam-water separation.
ZOZEN WNS series horizontal internal combustion boiler is a boiler shell type 3 passes wetback oil/gas-fired boiler. Smoke tube and tube sheet connection is expanded first to eliminate the gap between them, then adopt automatic argon arc welding to Sufficient steam storage room and heating area makes boiler to generate high quality steam and high thermal power the stress and expand boilers working life.
According to different new employees, ZOZEN Boiler has made professional and new growth training plan. Through systematic induction training and boiler knowledge training, new employees can not only feel the humanistic care of ZOZEN Boiler, but quickly understand the strong power of the enterprise.
ZOZEN WNS series gas-fired hot water boiler adopts packaged structure, which is convenient and quick for installation to save a lot of basic construction costs for the enterprise. Its internal structure adopts large-diameter waveform strove furnace which can effectively absorb heat expansion to add the radiation heating surface and ensue the low emission of NOx with the advanced low-nitrogen burner to improve the fuel utilization. What's more, its thread smoke tubes have scientific pitch and depth to further strengthen the convective heat transfer and make boiler's thermal efficiency reach 95% and above.
