Pulverized coal burner structure classification
A pulverized coal burner is a device that feeds pulverized coal into a furnace for combustion.
1. Swirling burner. The primary air carrying pulverized coal and the secondary air without pulverized coal are connected to the burner by different pipes. The pulverized coal and air can be thoroughly mixed and form a recirculation zone. Each boiler can be configured with 4 to 48 burners.


2. DC burner. The nozzle is narrow, and the primary and secondary air do not rotate in the burner. The pulverized coal can be completely burned therein.
The heated surface separates the heated surface from the heated surface and the heated surface. Modern large and medium-sized boilers are constructed of water-cooled walls, whereby the water-cooled wall (ie, the heated surface) absorbs the radiant heat in the furnace to evaporate the water into saturated steam. In order to increase the radiant heating surface without increasing the volume of the furnace, the large boiler can be double-exposed water-cooled wall. The superheated heating surface can be divided into a screen type superheater heating surface arranged on the upper part of the furnace and a convection superheater heating surface arranged in the convection flue. The former absorbs radiant heat in the furnace; the latter absorbs convective heat.


The air preheater is installed at the tail of the boiler flue to recover the residual heat of the flue gas and increase the temperature of the combustion air. For high-parameter, high-capacity boilers to increase hot air temperature (>300℃), it is often necessary to stratify the air preheater and the economizer.

Three - Return Residential Coal Fired Boilers Coal Powered Boiler Easy Installation 0

Description

The coal-fired steam boiler is a horizontal three-return hybrid boiler in which a bundle of threaded tobacco pipes is arranged. A light pipe water cooling wall is installed on the left and right sides of the furnace. The movable grate is equipped with a blower and an induced draft fan for mechanical ventilation.
Fuel combustion process: After the fuel is fully combusted in the furnace, the flame enters the rear part of the body through the flue gas passage of the intermediate furnace wall, and is turned to the front smoke box by the combustion chambers on both sides, and then the front smoke box is folded back into the inner tube bundle. After entering the dust collector through the rear smoke box, it is finally drawn by the induced draft fan through the flue to the chimney and discharged to the atmosphere.
