Hot oil boiler HOB

coal

In the rotary grate combustion system, from the moment the coal is poured into the grate from the service bunker, it moves towards the furnace with the rotation speed of the grate. When it first enters the furnace, the coal first starts to release its moisture with the effect of radiation heat, starts to gasify and release its volatile-flammable hydrocarbons with the increase in temperature and completes the fixed carbon combustion in the later parts of the grate. The combustion of all components of the coal continues until the end of the grate. Since the combustion in the hot oil boiler is completely finished, the amount of slag remaining is very small and this is poured into the slag trough and taken out. All processes from loading the coal into the bunkers, burning and discharging the slag are fully automated with the PLC automation system. In this way, both a highly efficient combustion and a very low emission value are provided.
