commercial condensing gas boiler seller, ZOZEN launches the eco-friendly WNS series three-pass condensing oil-fired boilers

On August 25 of 2020, Wuxi ZOZEN Boilers Co., Ltd. officially held the quality management mobilization meeting. The basic design department, research and development department, process improvement department, equipment department, production department, quality assurance department, purchasing department, material planning department, all workers at the production lines and related leadership attended the meeting.

During the "Thirteenth Five-Year Plan" period, China's oil refining industry will focus on transformation and upgrading, and continue to enhance comprehensive strength. It will vigorously eliminate backward production capacity and improve the scale and technology of its units. Among them, the boiler as an important piece of energy equipment is indispensable in the petroleum refining process.

ZOZEN DZL series coal-fired steam boiler has sufficient output and high thermal efficiency. The boiler is packaged with a compact structure, so it has relatively low construction costs. The boiler is a horizontal three-pass water and fire tube chain grate boiler. In the single drum with a longitudinal layout, threaded smoke tubes from the convection heating surface, while the boiler drum and water-cooled walls on both sides form the radiation heating surface in the furnace. The boiler thermal efficiency can reach 82% and above, commercial condensing gas boiler seller.

In the Harbin area, Heilongjiang Branch of Industrial and Commercial Bank of China, Harbin Investment Group, Harbin Coslight Battery, Veolia (Harbin) Thermal Power and other companies all use eco-friendly gas-fired boilers produced by ZOZEN. It is understood that in the industrial gas-fired boiler market, the coverage rate of ZOZEN gas-fired boiler is as high as 90%. This is not only due to the strength of ZOZEN with a wide range of boiler types and a capacity ranging from 1 to 110 tph, which can meet the demands of enterprise production and heating, but also due to the advantages of the boiler itself.

The structural design focuses more on details. The sealing of both sides of membrane wall and drums adopt comb plate. The boiler features a drainage system of condensation water in convection zone to prevent the corrosion of furnace body by acid condensate. Advantages: reduce the frequent maintenance of furnace and extend the boiler working life, commercial condensing gas boiler seller.

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.

The relationship between enterprise’s sustainable development capacity and environment and society is mutually promoted and coordinated. Taking the social responsibility of protecting environment is greatly beneficial for the sustainable development of enterprise. Industrial boiler manufacturer ZOZEN has its own understanding of ecological civilization: product research and development relies on the market and it is also necessary to guide the market and provide more support for the industry in the aspects of energy saving, emission reduction, environmental protection and resource recycling. For over 30 years, ZOZEN has more than 400 kinds of boilers in four main fields that are gas-fired/oil-fired boilers, coal-fired boilers, biomass-fired boilers and thermal oil heaters and keeps launching green products and project solutions to ensure the healthy development of the whole industrial chain.
