Rotary Grate Boilers

ROTARY GRATE BOILERS

In this combustion system, coal moves into the furnace with the speed of rotation of the grid from the service bunker through the grid. At first, the coal starts to release its moisture when it comes into the furnace, then begins to gase up with increase the temperature, releases volatile-combustible hydrocarbons and completes the burning of fixed carbon in the further part of the grid. All components of the coal continue to burn until the end of the grid.

The amount of residual slag is very small because the burning is complete and it falls out into the slag tank and moved out.

Charging of the coal to the bunker, ensure the burning and discharge of the slags are performed by PLC automation system. In this way, both high efficiency combustion and very low emission values are achieved.
