FT high temperature boiling furnace with strong hot air
Performance characteristics of the boiling furnace is to mechanically feed 0.5-10mm of coal (the mined raw coal can be sieved) into the air distribution plate in the furnace, and the high pressure makes the coal particles and furnace charge boil through the cloth sealing plate. Since coal particles only account for about 1% of the burden, the contact area with air is large and the relative movement speed is large during boiling combustion, the time from raw coal entering the furnace to being discharged out of the furnace is long, and some inferior fuels with high ash content and low calorific value that are difficult to burn through in other furnace types can also burn stably to reach a high degree of burnout, so the temperature is relatively uniform and the combustion efficiency is high. 1. Strong adaptability to combustion materials, and can burn various inferior coal and slag (calorific value greater

Product Description
Performance Characteristics
Boiling Furnace is to mechanically send 0.5-10mm of coal (the mined raw coal can be sieved) into the air distribution plate in the furnace, and the high pressure makes the coal particles and charge in the furnace boil through the air distribution plate. Since coal particles only account for about 1% of the burden, the contact area with air is large and the relative movement speed is large during boiling combustion, the time from raw coal entering the furnace to being discharged out of the furnace is long, and some inferior fuels with high ash content and low calorific value that are difficult to burn through in other furnace types can also burn stably to reach a high degree of burnout, so the temperature is relatively uniform and the combustion efficiency is high.
1. It has strong adaptability to combustion materials, can burn all kinds of inferior coal and slag (calorific value is greater than 7270KJ/Kg), and the combustion efficiency is as high as 95% or more;
2. The furnace body is evenly heated and has long service life.
3. Flexible operation, good adjustment performance, fast furnace temperature rise, restart after shutdown, 2. 30 minutes full load operation;
4. Uniform heat supply and stable temperature can increase dryer output by 50-70%, save coal by more than 50% compared with other furnace types, and slag carbon content less than 1% is a good admixture for cement;
5. Low labor intensity and high degree of automation;
6. Can be used in vertical mill, rotary dryer, three-cylinder dryer, vertical dryer, etc.
Main Technology
1. Isobaric air chamber, two-stage combustion, U-shaped combustion section can separate and collect unburned fine carbon particles, and can prolong its burning time (when two-end combustion is not used, the coal particles entering the furnace should be less than 10mm, if the coal particles are limited to 0-5mm);
2. The air distribution device with large pitch variable diameter air cap is adopted, it has good fluidization quality and combustion process, and reduces the influence of uneven air distribution caused by side wall effect;
3. Adopt large excess air coefficient, strengthen air agitation in the furnace, strengthen combustion, make coal burn fully in the furnace, uniform temperature, and convenient control;
4. Adopt reasonable suspension section structure, low flue gas flow rate and small amount of fine ash carried away, the maximum temperature of heating flue gas can reach 1050 ℃, and the coal particles burn more than 95%.
