In the travelling grate combustion system, after the coal is poured from the service bunker to the grill, it moves towards the furnace with the rotation speed of the grill. When it enters the furnace, with the effect of radiation heat, the coal first starts to release its moisture, then gasification and volatile-combustible hydrocarbons are released with the increase in temperature and completes the fixed carbon combustion in the later parts of the grate. All components of the coal continue to burn until it reaches the end of the grill.
Since the combustion is complete, the remaining amount of slag is very small, which is poured into the slag vat and taken out. All processes from loading the coal to the bunkers, burning and discharging the slag are carried out fully automatically with the PLC automation system. In this way, both a highly efficient combustion and a very low emission value are provided.
