The series of coal-fired boilers pull part of the rising tubes on both sides of the collector box to the furnace, and then introduce the bottom of the drum side and form the top heating surface with the bottom of the drum covered with insulation material. The new furnace structure successfully solves the problem that the bottom of the drum is directly exposed to high temperature flame radiation and avoids the defect of “bulge”. Steam boiler design push-pull gate ash cleaning device, the gate adopts heat resistant cast iron finishing seal structure, so as to effectively prevent secondary combustion deformation and grate air leakage.

8 Ton chain grate boiler arch design using the latest scientific research achievements. The boiler rear arch is low and long, the outlet section is anti-inclined, the front arch Angle of 45° echoes the rear arch, forming inverted “α” flame, which is conducive to the combustion of inferior coal, coal adaptability is strong. The combustion equipment of coal-fired quick loading boiler is chain grate. Host for single drum longitudinal arrangement, drum arranged in a single return threaded pipe, left and right sides of the chamber of a stove or furnace is equipped with light water wall tube, part of riser pipe of furnace top, the bottom of the drum with brick, don’t accept high temperature flame radiation, on both sides of the drum under a symmetrical two convective flue, another exclusive configuration at 750 mm from the center line of the drum assembly water wall tube, Thoroughly solve the barrel and container thermal expansion and contraction caused by tearing the defects of weld.

The water supply of coal-fired steam boiler is completed by boiler water pump, and the softening water is completed by the water supply pipe economizer, and then enters the drum, and then enters the left and right collector box by the down pipe. The water wall on both sides is thermally vaporized to produce steam, which enters the soda water separator in the drum and enters the process requiring heat through the main steam valve after separation. The boiler automation level is high, boiler feed water automatic regulation, high and low water level alarm, low water level interlocking protection, lead and blower interlocking protection. Boiler coal, slag and other operations mechanization, reduce the labor intensity of workers, complete supporting auxiliary machines.

8 Ton chain grate boiler two wing flue set, so that the smoke into the front smoke box smoothly. The temperature of the front tubesheet is the same and lower than 600℃ to avoid tubesheet cracks caused by temperature stress. The large parts of the coal-fired boiler (mainly the upper body and the lower base) have been assembled in the factory. After the large parts of the user’s boiler (mainly the upper body and the lower base) are in place, all the interfaces, auxiliary machines and pipeline systems need to be completed to run.
