The new DZL series coal fired boiler is a single-drum vertical water-fire tube shell boiler, and the combustion equipment is a chain grate. The water walls on the left and right sides of the furnace are radiant heating surfaces, the two wings of the furnace are convective heating surfaces, and the convection heating surfaces of threaded smoke pipes are arranged in the drum. Shield shell.

This series of coal fired steam boilers use the latest scientific research results, such as: arched tube sheet, threaded smoke tube, etc., to solve the problems of shell-type boiler tube sheet cracks, bulging at the bottom of the drum, tube bursts on the water wall, low thermal efficiency, and insufficient output.

 

Coal Fired Boiler Burning process

The fuel falls from the coal hopper to the front of the grate. With the operation of the grate, the coal undergoes preheating, dry distillation, ignition, and embers. The slag falls into the slag hopper and is discharged from the furnace at any time by the slag remover. The flue gas is in the front and back arches. The throat between the throat can form a vortex to fully mix with the air, heat the front arch, improve the fire conditions, enter the two-wing convection tube bundle through the exit smoke window on the upper part of the arch, enter the threaded smoke pipe through the front smoke box, and pass through the economizer and dust collector. The induced draft fan is led to the chimney and discharged.

Technical characteristics

(4) The structure is compact, and compared with the same type of boiler, the overall size is small, which saves the investment in the infrastructure of the boiler house.

(5) Stable operation, convenient adjustment and sufficient output. Has a certain overload capacity.

(6) Threaded smoke tube is used to enhance heat transfer, which improves the heat transfer coefficient and thermal efficiency. Because the flue gas has a disturbing effect in the tube, it is not easy to accumulate dust in the smoke tube, which plays a role of self-cleaning.

(7) In the furnace, a high-efficiency and energy-saving furnace arch made of integrally cast heat-resistant concrete is used to improve the coal ignition conditions, and an independent air chamber is used to achieve reasonable air distribution, so that an aerodynamic field conducive to combustion is formed in the furnace. Expand the adaptability of coal types.

(9) The arch of the boiler and the outlet smoke window have a certain effect of dust removal. The original dust concentration of the boiler is controlled below the standard, which ensures that the smoke and dust emission of the boiler meets the national environmental protection regulations.

(10) The secondary air is arranged at the throat of the furnace arch, which can effectively organize the volatile matter in the fuel to mix with the air, promote the full combustion of the volatile matter in the furnace, and improve the fuel burnout efficiency.
