ZOZEN SZS series condensing gas-fired boilers are typical high-efficiency, energy-saving and environment-friendly boilers with large furnace volume, sufficient radiant heating surface, sufficient fuel combustion and high thermal efficiency of 98%. With advanced combustion equipment, the emission of nitrogen oxides can be less than 30 mg/nm3.
The processing of corrugated furnace requires blanking, rolling, welding and flaw detection, and some parts that can not be welded automatically will be completed by reliable welding workers.
The production of an industrial boiler with good quality will go through several links, such as blanking, welding, assembly and inspection. ZOZEN Boiler has a set of comprehensive production system and quality control system to assure product quality in the manufacturing process.
SZL series vertical dual drums chain grate water pipe steam and hot water boiler, adopts quick fitting and assembly structure. The 4-6t/h boiler is of quick fitting pipe structure, exit shop after completely assembled, the boiler of 6-35t/h is composed of 2 main components. The upper assembled components is the body heat accepting part, and the lower assembled component is of combustion equipment.
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.
The production base of ZOZEN Boiler creates strict production procedure, each performs its own functions. The painting workers are responsible for the boiler painting, while the welding workers are cooperating with each other to do the welding work.
ZOZEN WNS series oil-fired and gas-fired boiler is designed with large-diameter corrugated furnace and threaded smoke tube, which makes the heat transfer of the boiler more efficient. With the condenser and economizer installed, the thermal efficiency of the boiler can reach over 98%, which is well received by the market.
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.
