ZOZEN Boiler has optimized the three-pass gas and oil boiler to the two-pass type. The corrugated furnace with major diameter and the threaded smoke tubes enhances the heat transfer efficiency. The thermal efficiency of the boiler reaches over 98%. Also, the low-NOx burner could control the emission below 30mg/Nm³, which meets the environmental protection policy. ZOZEN WNS series gas/oil-fired boiler is well received by industrial plants due to its compact structure and packaged delivery with convenient installation.
Thermal oil heaters are widely used in chemical industry, printing and dyeing, edible oil processing and other industries because of their low pressure, high temperature and precise temperature control. ZOZEN gas-fired thermal oil heater adopts multi-loop round coil structure, with large heat exchange area, high thermal efficiency and fully automatic and safe operation.
Chain grate is a kind of common mechanized combustion equipment, which is used for biomass boiler, coal-fired boiler and thermal oil heater. The grate is used to make the solid fuel burn evenly. The fuel enters the grate through the hopper, and enters the hearth with the movement of the grate to start the combustion process. According to different fuels, ZOZEN Boiler also designs different grate widths and lengths and air distribution systems to ensure that the fuels can be stably ignited and fully burned.
ZOZEN Boiler is a well-known industrial boiler manufacturer in China. With more than 30 years' development, ZOZEN Boiler has excellent team and advanced equipment, strong design and manufacturing strength with reliable boiler quality. ZOZEN Boiler owns gas-fired boilers, biomass-fired boilers, coal-fired boilers and thermal oil heaters, which are widely used in various industries.
As an industrial boiler manufacturer, ZOZEN Boiler has advanced production technology and equipment in the industry, and the products of thermal oil heaters are complete in model and wide in capacity. ZOZEN Boiler owns the gas-fired and oil-fired thermal oil heaters, with the boiler capacity ranging from 1.2 million kcal to 25 million kcal. it takes the heat-conducting oil with larger heat capacity as medium. At the same time, the boiler is equipped with various safety detection devices and intelligent control system to control the temperature within 1℃, which has outstanding advantages such as high thermal efficiency, accurate temperature control and environmental protection.
ZOZEN SZS series gas-fired boiler adopts the D-type chamber structure, the large furnace ensures the sufficient combustion and radiation heating area. The thermal efficiency of the boiler can reach up to 98%. Also, the reasonable arrangement of steam and water separator effectively reduces the water content of the steam.
ZOZEN Boiler is good at designing different boiler systems and accessories according to different boiler room areas. This group of pictures shows the boiler condenser specially designed by ZOZEN Boiler, which is installed at the end of the boiler flue. The working principle is to use the waste heat in the boiler flue gas to heat the boiler feed water, which effectively reduces the heat loss and improves the thermal efficiency of the boiler system.
Boiler air preheater is a preheating device. It uses the flue gas to preheat the air before entering the boiler to a certain temperature, which can not only improve the combustion efficiency, but also effectively reduce the exhaust gas temperature and improve the thermal efficiency of the boiler.
