Welding is an important working procedure in boiler production, which is generally divided into automatic welding, semi-automatic welding and manual welding. In the production base of ZOZEN Boiler, a professional boiler manufacturer, front-line welders are ensuring the quality of boiler welds with superb technical level, lofty ideological awareness and strong sense of responsibility.
ZOZEN Boiler owns advanced equipment in the intelligent production base in China. As a professional industrial boiler manufacturer, ZOZEN Boiler always pay attention to the boiler quality and focus on R&D of advanced technologies. In the future, ZOZEN Boiler will develop more advanced equipment and technologies.
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.
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 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.
