Fluidized bed coal hot air furnace (boiling furnace) is widely used in industrial furnace for features like relatively high speed of movement, high burning speed, high burnout degree, energy-saving and environment protection, etc.

　　Boiling furnace is widely used in drying and roasting industrial raw materials and products like slag, clay, sludge, carbide slag, compound fertilizer, industrial gypsum, gypsum board, iron powder, quartz sand, yellow sand, laterite, sulfur concentrate, siderite, zinc leaching residue, white carbon black, coke,coal dust, coal slime, etc.

　　1. Wide fuel flexibility;
　　2. Furnace combustion temperature (850-1100℃), uniform operation temperature, stable heat supply;
　　3. High combustion efficiency;
　　4. Easy ignition;
　　5. Hot exhaust gas outlet temperature is adjustable;
　　6. Carbon content of ash is less than 1%;
　　7. Clean combustion, low nitride content in flue gas;
　　8. Mechanical-electrical integration, thermal control and intelligent control, low labour intensity;
　　9. Long service life, less quick-wear parts, low maintenance cost.
