Rotary Kiln flue gas waste stream in the same direction inclined Rotary kiln.By the way downstream into the Rotary kiln exercise.We will talk about this in the way the flue gas downstream work. Flue gas waste stream in the same direction, the inclination of the Rotary kiln.Solid rotational motion and gravity to move from high-end to low-end of the Rotary kiln.The combustion air enters the cold (ambient), containing max.Oxygen level (21%).Back flowing into the Rotary kiln, air heating, and gradually loses its oxygen burning solid - becomes substantially gas, so that the back of the Rotary kiln exit gas containing a small amount of oxygen (6%) and high temperature (temperature at 1000 ℃). Receive garbage (solid) is a cold front hit the Rotary kiln area, where the atmosphere is oxygen and high temperatures.Make the necessary auxiliary fuel, lighting up the garbage into the incinerator.
