Efficient boiling furnace

The combustion method of high-temperature flue gas boiling furnace is different from that of chain grate furnace and hand burning furnace. The fuel is crushed into particles below 10mm and uniformly sent into the furnace by speed regulating machinery. Controllable high-pressure air is injected into the furnace bed through the air cap holes on the air distribution plate. The fuel burns in a fluidized boiling state under the action of high-pressure air, producing high-temperature hot flue gas. The combustion inside the furnace is controlled by controlling the coal feeding, air volume, air pressure, and exhaust gas temperature Make combustion heating have good controllability; Boiling furnaces can use inferior fuels The low generation of nitrides and easy desulfurization have significant environmental advantages. Today, with the increasing awareness of energy conservation and environmental protection, encouraging and promoting clean combustion technology of coal has been included in China's energy conservation law. Boiling furnaces have been widely used in metallurgy, chemical industry, building materials, non-metallic minerals and other fields to provide heat energy for drying and roasting various raw materials and materials such as slag, clay, coal powder, compound fertilizer, natural gypsum, non-metallic mineral powder, etc.

Main performance characteristics

1. Good fuel adaptability, combustible with bituminous coal, anthracite coal, and various inferior fuels such as coal gangue, stone coal, coal slag, etc;

2. The fuel preparation is simple, and the raw coal can be crushed to below 10mm before being put into the furnace for use;

3. High combustion efficiency, can burn small coal particles thoroughly, with a carbon particle burnout degree of over 98% and a thermal efficiency of over 93%;

4. Stable heating, uniform temperature, wide range of heating adjustment, heating temperature below 1000 ℃, stable and adjustable;

5. Automatic overflow of slag, ash residue can be comprehensively utilized, and ash residue has good activity without high-temperature melting, making it a good admixture for cement;

6. High degree of mechanization, thermal control can provide manual control, intelligent thermal instrument control, and microcomputer control according to user needs, with simple operation and convenient maintenance;

7. Good environmental protection effect, less harmful substances in the exhaust, low NOx generation, low-cost desulfurization in the furnace, allowing sulfur in the fuel to be discharged in a solid state, reducing atmospheric pollution caused by SOx;

8. It can be ignited as a backup, saving ignition fuel and time. It can be ignited for 16-24 hours, with a maximum of 36 hours.
