    Single Drums Water Tube With Flake Chain Grate Industrial Steam Coal Fired Boiler

    The characteristics of the boiler
    1. Prevent cracks. The arch tube and the threaded tobacco tube are used to form the drum, so that the drum is changed from the quasi-steel body to the quasi-elastic body structure, and the tensioning members of the tube plate area are eliminated, thereby reducing the stress. The pipe was changed from two return strokes to a single return stroke, which solved the problem of cracks in the tube sheet.

    2. Prevent boiler casing bulge. Due to the arrangement of the riser row in the lower part of the drum, the dead water area at the bottom of the drum is eliminated, so that the sludge is not easily deposited, and the high temperature zone of the drum can be well cooled, preventing the bulge in the lower part of the boiler shell.

    3.  Improve combustion efficiency. The high-efficiency heat transfer thread pipe is used to obtain the enhanced heat transfer effect, which achieves the characteristics of heating and output of the boiler, and improves the thermal efficiency of the boiler.

    4. Compact. Compared with the same type of boiler, the external dimensions are small, saving the investment in the boiler house infrastructure.

    5. Smokeless ash accumulation. The use of a threaded pipe enhances heat transfer and improves the heat transfer coefficient and thermal efficiency. Since the flue gas is disturbed in the pipe, the pipe is less likely to accumulate ash and acts as a self-cleaning.

    6. The fuel is easy to burn. In the furnace, high-efficiency energy-saving furnace arch with integral heat-resistant concrete is used to improve the coal fire condition. The independent air chamber is adopted to achieve reasonable air distribution, which forms an aerodynamic field favorable for combustion in the furnace, thereby expanding coal. 

    7. Eco-Friendly. The furnace arch and outlet smoke window of the boiler have certain dust removal effects. The original dust emission concentration of the boiler is controlled below the standard to ensure that the boiler dust emission meets environmental protection regulations.
