Industrial boiler brickwork functions and requirements
All the flue gas of the combustion chamber of the industrial boiler is discharged through the channel enclosed by the furnace wall. The industrial boiler wall separates the fire wall, the high temperature flue gas and the parts of the heating surface from the outside. It is an important part of the industrial boiler's body.
The main functions of the industrial boiler wall are:
1. Insulation, prevent heat loss of industrial boiler, ensure industrial boiler operation economy.
2. Sealing effect, leaked-in cold air for the tight sealing of the industrial boiler wall, not only increases the heat loss of the industrial boiler grate, but also causes the increase of the power consumption of the induced draft fan, thus reducing the thermal efficiency of the industrial boiler by about 0.4%-0.5%
3. Form flue gas passage ,make the flue gas flow through the heating surfaces in a certain channel of industrial boiler .
