AI Technical Summary

Technical Problem

In existing heat carrier heating furnaces, dust in the flue gas is easily adsorbed on the upper and lower convection section coils, causing ash blockage and affecting the normal operation of the equipment.

Method used

By adjusting the flue gas flow path, the path of dust in the flue gas in the settling chamber and the lower convection section of the serpentine tube was adjusted, as was the path of dust in the flue gas in the ash hopper. The flue gas flow path was adjusted, the path of dust in the flue gas in the settling chamber was adjusted, the path of dust in the flue gas in the settling chamber was adjusted, the path of dust in the flue gas in the ash hopper was adjusted, the flue gas path was adjusted, the flue gas flow was adjusted, and the flue gas flow was adjusted. The flue gas flow direction was optimized, so that the flue gas flows from bottom to top in the lower and upper convection chambers, reducing the adhesion of dust on the serpentine tube.

Benefits of technology

This effectively reduces the adhesion of dust in the flue gas to the lower and upper convection sections of the coil, alleviating or even avoiding ash blockage problems and improving the reliability and service life of the equipment.

Abstract

The utility model discloses a coal-fired heat carrier heating furnace which comprises a furnace body assembly, a fire grate, an ash falling hopper, an upper convection section coil pipe and a lower convection section coil pipe. Wherein a combustion chamber, an upper radiation chamber, a lower radiation chamber, an upper convection chamber, a lower convection chamber and a settling chamber are arranged in the furnace body assembly, the combustion chamber is located below the lower radiation chamber, the lower radiation chamber is located below the upper radiation chamber, and the combustion chamber, the lower radiation chamber and the upper radiation chamber are sequentially communicated; the settling chamber is arranged on one side of the lower radiation chamber and located below the upper radiation chamber, the upper end of the settling chamber is communicated with the upper radiation chamber, the upper convection chamber is located on one side of the upper radiation chamber, and the lower convection chamber is located on one side of the settling chamber. According to the utility model, dust in smoke can be prevented from being adsorbed on the upper convection section coil pipe and the lower convection section coil pipe, and the problem of dust blockage on the upper convection section coil pipe and the lower convection section coil pipe can be relieved and even avoided.
