fire tube boiler capacity 4, with 30-years innovation, the manfacturing level of ZOZEN boiler is industry leading
fire tube boiler capacity 4, As an independent national brand whose products have been exported to more than 100 countries and regions, ZOZEN Boiler has set the international quality standards for itself from the beginning. Standardized production process and complete quality management system have enabled ZOZEN Boiler to successfully obtain international authoritative certifications such as ASME (USA), PED (EU) and DOSH (Malaysia), and also win the recognition of ZOZEN’s boiler quality from customers around the world.
In March 2019, Wuxi Zozen Boilers Co., Ltd. successfully passed the French BV certification and became an in-depth factory inspection company of Alibaba International Station. Alibaba cooperated with the French BV certification and comprehensively judged companies' product capabilities, quality control, research and development capabilities, and trade capabilities, which further proved that ZOZEN's comprehensive strength is strong, and all indicators fully meet the boiler export certification standards.
ZOZEN SZL series coal-fired steam boiler is package or shop-assembled water tube boiler with double-drum and chain grate structure.Boiler with capacity of 6-35 tph is shop-assembled structure, which is composed of 2 parts, upper part is heat absorbing surface and lower part is combustion equipment.
The thermal oil heater is also known as an organic heat carrier boiler. It uses the thermal oil as a heat medium and uses a hot oil circulation pump to force the medium to circulate in the liquid phase. After transferring the thermal energy to the heating equipment, the thermal oil returns to the furnace to be reheated. With the feature of low-pressure and high-temperature heating, the thermal oil heater has wide applications. ZOZEN has provided thermal oil heaters to many building material companies, such as Huayuan Mineral Wool Board, Ameisizhuang Mineral Wool Board, Shanghai High-New Science & Technology and etc.
The main advantage of ZOZEN’s circulating fluidized bed boiler lies in the direct control of pollutant emission during the combustion process. This type of boiler adopts low-temperature combustion technology. The temperature of normal boiler furnace is as high as 1400-1500°C during combustion, while that of circulating fluidized bed boiler furnace is within a lower temperature range of 800-900°C, which reduces the production of nitrogen oxides (NOx); meanwhile, by adding low-cost limestone to circulating fluidized bed boiler, sulfide (SOx) can be removed during fuel’s combustion.
In terms of welding technology, ZOZEN longitudinal and circumferential seam welding adopts advanced automatic submerged arc welding technology, and 100% X-ray detection is carried out on the welding seam to ensure the welding quality. The welding of the smoke tube and tube sheet adopts pre-expansion first to eliminate the gap between the tube and tube sheet, and then adopts the automatic argon arc welding technology, which can effectively eliminate the stress and extend the service life of the boiler, fire tube boiler capacity 4.
ZOZEN will always adhere to technology research and development, and continue to provide efficient and energy-saving boiler systems for enterprises, further contributing to the high-quality development of the domestic fine chemical industry.
