9mw steam boiler manufacturer of biomass, ZOZEN boiler actively improves the personnel selection and appointment system

Recently, as a leading enterprise in the domestic industrial boiler manufacturing industry, ZOZEN has successfully passed the examination of Jiangsu Market Supervision and Administration Bureau and has acquired the permission to engage in the installation, maintenance and reconstruction project of pressure-bearing special equipment with a sub project of boiler installation (A grade), which is valid until the August 7, 2024.

9mw steam boiler manufacturer of biomass, The YQW series gas-fired organic heat carrier boiler adopts a three-pass round coil structure. The coil end adopts a necked coil which can effectively protect the furnace wall at the boiler end. It is equipped with the advanced combustion device and automatic boiler operation system. The flame formed by the fuel combustion fills the round coil and transfers the radiant heat via the coil wall, which is the first pass. The high-temperature flue gas generated by combustion gathers at the rear furnace door and turns into the second pass where is the convention tube bundles area. After the convection heat exchange, the flue gas gradually cools down and then turns into the third pass via the front furnace door where is the bundles area. Finally, the flue gas passes the economizer and is exhausted into the atmosphere via the chimney.

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.

ZOZEN has set up a total of seven process stopping points throughout the production process, which are strictly controlled by different engineers, independent of each other and supervised each other, so that problems can be found and solved in time. If any workpiece is unqualified, it cannot enter the next process, which is the quality control of the entire production process of ZOZEN.

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.

This is an era of innovation. In the more than 30 years of development, ZOZEN Boiler insists on the innovation and the pursue of quality and details. Every ZOZEN person has kept the spirit of craftsmanship in the manufacture, inspection, installation and commissioning of industrial boilers to build the outstanding quality of ZOZEN Boiler, which has created today’s ZOZEN Boiler.
