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.
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.
Welding is an important working procedure in boiler production, which is generally divided into automatic welding, semi-automatic welding and manual welding.
SZS series gas-fired boiler is one of the popular boiler types of ZOZEN Boiler, which has the features of high heat efficiency, clean emission and full-automatic operation. This series of gas-fired boiler adopts large volume of combustion chamber and membrane structure, with sufficient combustion space and large heat transfer area, it effectively improves the fuel utilization rate.
Boiler heating surface is the main heat transfer equipment of boiler, which can be divided into main heating surface and auxiliary heating surface. In order to enlarge the heating surface of the boiler, ZOZEN Boiler has independently designed and produced various energy-saving equipment, such as economizer, condenser, air preheater, which can match the actual working conditions of different users.
Recently, a set of ZOZEN SZS series gas-fired boiler was shipped to Henan Province. The customer is a leading enterprise in the domestic metal products industry, mainly producing new materials such as steel cord and galvanized steel strand for radial tires. ZOZEN SZS series gas-fired boiler adopts the large furnace structure with sufficient heating area. It has the advantages of high thermal efficiency, sufficient steam output and energy conservation.
ZOZEN SZS series gas-fired and oil-fired boiler is a kind of horizontal internal combustion structure. The size of the steam drum and water drum is calculated professionally, and the steam drum is equipped with several steam-water separation devices, which can effectively improve the steam quality.
