ZOZEN Boiler is a well-known industrial boiler manufacturer in China. With more than 30 years' development, ZOZEN Boiler has excellent team and advanced equipment, strong design and manufacturing strength with reliable boiler quality. ZOZEN Boiler owns gas-fired boilers, biomass-fired boilers, coal-fired boilers and thermal oil heaters, which are widely used in various industries.
ZOZEN Boiler provided an energy-saving and environment-friendly WNS gas-fired steam boiler for a food enterprise in Suzhou. The gas-fired steam boiler adopts two-pass design, and the use of large-diameter corrugated furnace and threaded smoke tube make the heat transfer of the boiler more efficient. With the condenser and economizer installed, the thermal efficiency of the boiler can reach more than 98%.
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.
Boiler economizer is an energy-saving device installed at the tail of boiler flue. Its working principle is to heat boiler feed water into saturated water under drum pressure by absorbing waste heat in flue gas. As the economizer absorbs the heat of high temperature flue gas, it further reduces the exhaust temperature of flue gas, thus reducing the exhaust loss, improving the thermal efficiency of the boiler and effectively reducing the fuel consumption of the boiler. It is one of the important equipment of boiler system.
SZS series gas-fired boilers are the main energy-saving and environment-friendly boiler products in the market at present. In order to reduce the heat loss on the surface of the furnace body, the outer package of the gas-fired boiler adopts the whole frame structure, which reduces the connecting plate between the frame and the drum, and effectively reduces the heat loss caused by heat conduction. In addition, the outer guard plates of ZOZEN SZS series gas-fired boilers can be customized as needed.
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.
The boiler is additionally provided with an air preheater at the end of the flue gas, and the air is preheated to a certain temperature with the heat carried by the flue gas of the boiler. The heated air enters the combustion room again, which not only accelerates the drying, ignition and combustion processes of the fuel, ensures the stable combustion in the boiler, but also improves the average temperature level in the boiler, thereby strengthening the radiation heat transfer in the boiler and effectively improving the thermal efficiency of the boiler.
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.
