There's a growing demand for the heating boilers due to the season. Previously, ZOZEN Boiler cooperated with a heating company in Tianjin to provide three sets of 29MW packaged gas-fired hot water boilers, which accelerated the completion of the project.
ZOZEN Boiler is a professional manufacturer of industrial boilers in China. ZOZEN Boiler entered the boiler industry in 1988 and took root in the boiler industry, always taking manufacturing high-quality boilers as its responsibility. Through the wonderful video, we recorded the ZOZEN people who work hard in the front line of production. They always adhere to the quality and create ZOZEN good-quality boiler products. After years of development, ZOZEN Boiler has won a good market reputation by virtue of its reliable quality and perfect service.
Heat treatment is an essential part of the manufacturing process, involving heating a metal or alloy to a specific temperature and then cooling it to harden the material. In the manufacturing process of boilers, the following pressure components require post-weld heat treatment: alloy steel pressure components and carbon steel pressure components which include butt joints with wall thickness greater than 30mm, the cylinders of internal combustion boilers, and T-joints with tube sheet wall thickness greater than 20mm. As a professional industrial boiler manufacturer, ZOZEN Boiler always strictly follows the boiler safety technical specifications to conduct heat treatment on specified boiler components, which effectively reduces the residual stresses in the material that have been introduced by welding and improves the boiler performance.
Thermal oil heater is a kind of new heat energy equipment with low pressure and high temperature, playing an important role in various industries. The thermal oil heater has wide adaptability of fuels, is suit for natural gas, coal gas, marsh gas, diesel, light oil, etc. The heat exchange surface adopts three-pass round coil tube structure, which features more sufficient heating surface. It is also equipped with an advanced burner to ensure the NOx emission below 30mg/m3. The waste heat boiler, air pre-heater and economizer are installed on the tails of the thermal oil heaters to effectively improve thermal efficiency, which can reach above 98%.
