Decrypt the combustion process of the DZL chain grate steam boiler. The new DZL series 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. The front and rear arches are made of a new process of integral casting and ramming of heat-resistant concrete. The outside of the boiler main body is a three-dimensional shape. Shield shell.

The combustion process of the boiler:

The fuel falls from the coal hopper to the front of the grate. With the operation of the grate, the fuel 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 throats 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 smoke window at 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.
