- The smaller the measurement of the fuel items, the greater the contact with the air (oxygen) and the better the burn. Pneumatic combustion and fluidised bed combustion systems are examples of this.
- In the pneumatic combustion system; when the fuel is sent into the furnace in a turbulent way, small particles burn in the air as they draw circles in the furnace and fall on the grille. The coarse parts complete the burning on the grille.
- When the part deposited on the grid is mixed well, very good combustion is obtained.
- With this system, 0.20 mm in size, cheap dust coal, tree dust, sunflower husk, ripped wastepaper , cotton wates waste etc. ripped fabric waste is burned successfully.
