The hot air rotary furnace is based on the temperature requirements of the terminal equipment, and outputs equipment suitable for temperature and a certain flow of hot flue gas. On the basis of meeting the basic requirements, we have focused on the following aspects:
1. The hot air rotary furnace realizes the detection of the temperature inside the furnace during the operation to meet the wind temperature and air volume required by the terminal equipment. The burner has a large adjustment range, and the flame length and diffusion angle can be reasonably matched with the furnace, and it is equipped with automatic ignition and fire detection to ensure safe and stable operation;
2. The furnace of the hot air rotary furnace adopts a reasonable steel structure to support the body; the refractory material with good performance is selected, and the secondary air cooling method is adopted to ensure that the surface temperature of the furnace body meets the technical requirements;
3. Reasonably arrange the furnace inspection port and observation hole, and the structural design is flexible to open, close tightly, and reduce the phenomenon of furnace gas spillage and cold air inhalation;
4, equipped with a complete thermal control system equipment, high degree of automation. Ensure strict air-fuel ratio and reasonable furnace pressure control of the hot air rotary furnace to minimize heat loss;
5. Meet the process requirements of low consumption and energy saving;
6. In terms of environmental protection, the harmful components of free carbon and NOX in the flue gas are mixed with the air by intensifying fuel to avoid the formation of free carbon. At the same time, reducing the excess air coefficient and flame temperature is an effective technical measure to reduce NOX. Achieve a reduction in the amount of NOx generated.
