Operating principle

According to the demand of high temperature and less dusts in furnace, based on traditional combustion methods, MBL coal burner adopts briquette smoke prevention and gasifying principle, improves the construct of fire grate and air inlet.

As the figure shows, raw (soft) coal is delivered into the burning chamber of coal burner by chain grate. Volatile materials in soft coal escape before combustion and burn in gasifying state; the remaining fixed carbon burn out on the fire grate; flue gas combusts with hot air and jets from outlet of coal burner. Cinder is discharged by tapping machine.

MBL coal burner has such characteristicss that combustion temperature is high and stable, coal burns fully, heat efficiency is high; flame length can be adjusted, flame is very clean. It is suitable for different type of furnace, and widely used. The flue gas discharge reaches the standard of environmental protection.

Advantages

（1）、Meet the demand of environmental protection      The flue gas discharge reaches the national second－class standard of environmental protection，i.e.  blackness of flue gas:lingemann 0-1 level, Dust content＜200mg/Nm³；SO₂＜850mg/Nm³。No secondary pollution, good operating conditions.

（2）、Visible energy－saving  Compared with common burning methods, energy reduces by 5~20%, carbon content in cinder is low, furnace temperature is stable.

（3）、High level of automation   Combustion process is controlled automatically, which keeps combustion at the optimum state, the quality of product is highly stable.

（4）、Wide adjusting range of temperature    Temperature of hot air can reach up to 1200℃, adjust easily.

（5）、Operate simply  Operator can be operate after simple training.

（6）、High security, there is no danger of explosion.

（7）、Equipment is durable   Overhaul period is longer than 4 years，low cost of operation, easy maintenance.
