Boiler economizer is an important energy saving device in boiler system. Its principle is to heat boiler feed water into saturated water under drum pressure by absorbing waste heat in the smoke. Economizer can be divided into cast iron economizer and steel tube economizer according to different manufacturing materials. This gallery displays the cast iron economizer produced by ZOZEN Boiler. The cast iron economizer is mostly used in boilers with pressure ≤2.5 MPa. If the pressure exceeds 2.5 MPa, the steel tube economizer should be adopted.
ZOZEN Boiler is good at designing different boiler systems and accessories according to different boiler room areas. This group of pictures shows the boiler condenser specially designed by ZOZEN Boiler, which is installed at the end of the boiler flue. The working principle is to use the waste heat in the boiler flue gas to heat the boiler feed water, which effectively reduces the heat loss and improves the thermal efficiency of the boiler system.
The dust removal door is also called the soot door, it is set up for the biomass-fired and coal-fired boiler for cleaning the dust and ash. The operator can check the ash accumulation status of the boiler and clean the ash and coke. Commonly, the dust removal door of the packaged boiler will be installed before delivery.
This is the ZOZEN WNS series gas-fired hot water boiler, it has the advantages of high thermal efficiency, good performance of energy conservation and the automatic control system. This boiler is designed with the large combustion chamber, which can ensure the sufficient burning of the fuel, to improve the boiler thermal efficiency.
In boiler system, a condenser is a heat exchanger used to condense the flue gas into a liquid state through cooling. In so doing, the latent heat is released by the substance and transferred to the surrounding environment. ZOZEN Boiler is a professional industrial boiler provider, we have rich experiences in providing the boiler system with suitable configuration.
Welding is an important working procedure in boiler production, which is generally divided into automatic welding, semi-automatic welding and manual welding.
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.
Boiler air preheater is a preheating device. It uses the flue gas to preheat the air before entering the boiler to a certain temperature, which can not only improve the combustion efficiency, but also effectively reduce the exhaust gas temperature and improve the thermal efficiency of the boiler.
