landlord gas and oil boiler services safety checks, ZOZEN thermal oil heaters become the common choice of many chemical enterprises

Facing the challenges of 2020, Wuxi ZOZEN Boilers Co., Ltd. is advancing all the way. At the beginning of the second half of the year, by virtue of excellent performance in project construction and management in the second quarter, ZOZEN was awarded as the “excellent project team” by Wuwei Yili project team for providing strong heat source support for Yili Group’s demonstration application project of green production and intelligent manufacturing, landlord gas and oil boiler services safety checks.

landlord gas and oil boiler services safety checks, Recently, relying on its solid strength, ZOZEN attracted the international fiber industry giant Lanjing Group to visit and inspect, and signed a long-term cooperation agreement with the company. Lanjing (Nanjing) Fiber Inspection Team stated that the visit was mainly due to the need to build distributed energy sources and plans to introduce multiple gas boilers. After understanding the company's actual needs, ZOZEN recommended SZS series gas-fired boilers for Lanjing (Nanjing) Fiber.

landlord gas and oil boiler services safety checks, ZOZEN SZL series chain grate boilers have high combustion efficiency, strong overload capacity, wide coal type adaptability. The boiler is mainly composed of upper and lower drums, convection tube bundles, water-cooled wall tubes, downcomers and headers. The upper and lower drums are longitudinal arranged. The combustion equipment adopts the chain grate with chain belt and is driven by a stepless speed change device.

Recently, ZOZEN YQW series thermal oil heaters gained favor of SOTRATECH in Mauritius, which is an energy company engaged in utilization and development of sustainable energy. This time SOTRATECH wanted to purchase one thermal oil heater for a local textile mill, providing heat energy for dying, printing, drying and other production progresses. The director of SOTRATECH said that ZOZEN thermal oil heater featured advanced production technology and strict quality test standards, then he ordered a set of 2.8MW YQW series gas-fired thermal oil heater from ZOZEN.

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.

landlord gas and oil boiler services safety checks, 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.

This project is of great significance to ZOZEN, promoting ZOZEN’s development in Central Asia and building a strong foundation in future international development.
