Product Description

Automatic Double Drum Longitudinal Chain Steam Boiler For Central Heating And Power Generation

 

Structural Features

 

1. SZL-type assembly pipe steam boiler, double drum longitudinal chain grate boiler. The boiler body is composed of vertical upper and lower drum tubes and convection tube bundle. Left and right sides of the combustion chamber equipped with a light pipe water wall tube.

 

2. The upper drum is equipped with a steam separator and a surface blowdown device, and the lower drum is provided with a regular blowdown device. Economizers are arranged at the rear of the boiler. Combustion part of the light chain grate to achieve mechanical coal, with a blower, induced draft fan for mechanical ventilation, and equipped with screw slag machine automatic slag.

 

3. The fuel falls from the coal hopper onto the grate and enters the furnace for combustion. After the flame passes through the dome, the flame is folded upwards to the convection tube bundle and enters the economizer and the dust collector through the outlet of the flue gas, which is then drawn by the induced draft fan Through the flue to the chimney to the atmosphere.

Performance Characteristics

 

1. Burning part of the light chain grate, both sides into the wind. Under the grate, there are six independent plenums. On both sides of the plenum, there is a ventilation mechanism. The air is blown into the lower air duct by the blower and enters the independent plenum through the air-conditioning mechanism.


2. The upper furnace wall factory assembled by the factory, the lower furnace wall and front and back arch made of refractory clay brick silicate fiber and insulation materials.
Fuel from coal hopper through the coal gate into the furnace combustion, burning embers cinder in the grate run into the slag hopper by the spiral slag discharge machine.

 

3. Boiler with electric control console, console with boiler thermal parameter display instrument, drum, induced draft fan opening indicator, remote control electric actuator button. Boiler feed water with automatic water supply device and with over-temperature alarm device.
