Product Feature:

This industrial coal fired boiler is mainly composed of a shell seal head, a furnace shell, a furnace top, a lower seal ring, a sky tube and a horizontal pipe. 

The water-cooled wall pipe of the light pipe is densely arranged on both sides of the furnace. 

The design structure is reasonable, the heating area is large, the flue gas flow is long, the heat transfer effect is good, and the exhaust gas temperature is low, so the thermal efficiency is high, the running cost is low, and the use is more economical.

Product Description:

This industrial coal fired boiler is specifically designed according to normal pressure. The top of the furnace body is provided with an air outlet. In addition, the boiler runs without pressure and the combustion operation is safe and reliable. After the fuel is burned on the grate, the flame passes through the low wall to the combustion chamber, and then the pipe is bundled into the rear smoke chamber. Compared with ordinary boiler on the market, our industrial coal fired boiler not only prevents the bottom of the shell from being irradiated by the high temperature of the furnace, but also reduces the temperature of the inlet of the high-temperature tube plate. What's more, it is supplemented by backwater injection. There is no dead water area at the bottom of the drum, which can effectively prevent the tube sheet from being too cold. Boiling and scaling and convex bulge at the bottom of the furnace, the flue gas turns to the smoke chamber to remove dust and reduce the original dust concentration.

Common system of the Industrial Coal Fired Boiler

1)Direct blowing type milling system:

The ground coal powder is directly sent to the furnace for combustion. It is suitable to use medium-speed and high-speed coal mills, which are suitable for grinding soft bituminous coal and lignite.

The medium-speed coal mill direct-blowing pulverizing system is divided into two types: positive pressure type and negative pressure type. Modern large-capacity boilers mostly use positive pressure systems.

2) Intermediate storage type milling system:

The characteristic is that the output of the coal mill and the fineness of the coal powder are independent of the boiler load, and it is suitable for the steel ball coal mill which can grind various kinds of hardness coal. Industrial Coal Fired Boiler is a boiler that burns coal. It refers to a thermal power plant that burns coal in a furnace to release heat and heats the heat medium water or other organic heat carrier (such as heat transfer oil) to a certain temperature (or pressure).
