gas fired hot water boiler for heating, ZOZEN biomass boilers have low fuel costs and good environmental protection effects

Innovation is critically important to ensuring a company’s future viability. Many times, innovation is viewed through the lens of new product development that drives new revenue growth. ZOZEN, who is one of the most influential industrial manufactures in Asia, is sparing no effort to innovate the power economized boilers, gas fired hot water boiler for heating.

Recently, data from the National Bureau of Statistics showed that China’s industrial boiler output from January to July in 2020 was 184,780.8 tph, a decrease of 24.8% year-on-year, showing a downward trend. Against the background of a sharp decline in the domestic industrial boiler industry, ZOZEN Boiler managed to overcome the difficulties and achieved a slight increase in output.

ZOZEN DHL series coal-fired boiler is field assembled and has an external drum, which has the advantages of compact structure, low steel consumption, and fast heating of the corner tube boiler. It also adopts the front and rear arch covering furnace structure to build the refractory concrete  in the lower section of the front wall of the furnace. The front arch is the fire arch, while the rear arch is the ignition arch.

As one of the project cores, the gas-fired boiler with a rated pressure of 3.82 MPa and a rated steam temperature of 450°C is a mid-temperature and mid-pressure boiler, which puts forward high requirements for the manufacturer’s comprehensive strength. Facing similar competitors, ZOZEN Boiler with rich project experience and excellent product performance provided a satisfactory gas-fired boiler solution for Changfeng Coking and successfully obtained the supplier qualification.

gas fired hot water boiler for heating, ZOZEN gas/oil-fired boilers adopt the large furnace design with wide fuel adaptability and sufficient fuel combustion. With the energy-saving device at the end of the flue gas duct, the boiler can improve the thermal efficiency to 98% and above. ZOZEN gas/oil-fired boilers have good energy-saving and eco-friendly effects to easily realize the ultra low NOx emission.

The waveform stove furnace is an important part of the WNS series of oil-fired/gas-fired boiler. This part is directly exposed to the radiation of high-temperature flame and erosion of high-temperature flue gas. The use of the axial expansion and contraction of waveform stove furnace can reduce the thermal stress generated by the shell, tube plate and furnace itself, and more importantly, reduce the stress concentration caused by the elongation of furnace at the connection between furnace and tube plate. At the same time, the waveform stove furnace strengthens the flue gas disturbance, effectively improves the heat transfer effect of unit area and volume, and further improves the thermal efficiency of boiler.

Industrial boiler belongs to special equipment and has high requirements for product safety factors. As the domestic well-known boiler supplier, ZOZEN has advanced mechanical equipment, mature manufacturing process and guarantee of boiler quality. In addition, via the innovation and development of ZOZEN’s professional design team, the structure and material of boiler proper are continuously improved and optimized to greatly extend boiler’s service life. It is also worth mentioning that ZOZEN’s automatic boiler control system with dozen kinds of safety protection interlocks can fully ensure boiler’s safety. In the aspect of environmental protection performance, ZOZEN boilers are also outstanding. The flue gas emission of ZOZEN boilers nearly meets the EU standards. The NOx emission is low to 30mg, which realizes the goal of low-nitrogen emission.
