ZOZEN normal pressure gas boiler is a horizontal wet-back type fire tube boiler, which adopts a large-threaded smoke tube and a corrugated furnace to increase the radiant heat absorption, strengthen the heat transfer effect and save fuel consumption, to achieve the goal of energy saving and consumption reduction. At the same time, the normal pressure gas-fired hot-water boiler adopts an intelligent control system, equipped with various safety interlocks such as overheat protection, protection against dry burning and water shortage, and leakage protection, which can supply heat and water stably for a long time.
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.
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.
Recently, ZOZEN Boiler has hold an event for name collection of the new cartoon characters. ZOZEN people can put forward wonderful names and have chances to win the presents that provided by ZOZEN Boiler. These photos show the excellent participants from each department of ZOZEN Boiler.
ZOZEN ZZ series medium-temperature and medium-pressure gas-fired steam boiler adopts "D" type 2 passes. It is double-drum natural circulation water tube boiler. The flue gas turns at the back of the furnace, enters the convection tube bundle of the second pass, then leaves the boiler body, and enters the economizer and condenser in sequence.
Boiler X-ray inspection is based on the difference in the absorption of X-rays by different material thicknesses. The X-ray inspection of boiler is to show the internal defects of materials, parts and welds from the film and image by using the X-ray perspective photography and real-time imaging of industrial television. Such as crack, shrinkage cavity, air hole, slag inclusion, undissolved, incomplete penetration and etc. The quality of materials or products can be evaluated by observing the nature, size and position of defects, so as to prevent major accidents caused by internal defects and poor processing of materials.
