Abstract

The invention discloses a coal bunker capable of preventing high-water coal from bonding. The coal bunker comprises a coal bunker body, wherein the coal bunker body is in the shape of a rectangular pyramid table which is wide in top and is narrow in bottom; open structures are arranged at upper and lower ends of the coal bunker body; one surface of the coal bunker body is an inclined surface, andthe other three surfaces of the coal bunker body are vertical surfaces; the inclined surface of the coal bunker body and the vertical surfaces opposite to the inclined surface are provided with loosening parts which slide along the inner wall; a pull part is rotatably arranged on the inner wall of the coal bunker body; a pull rod which passes through the coal bunker body to outwards extend is arranged on the pull part; a drive motor is arranged on the outer wall of the coal bunker body; and the output shaft of the drive motor is connected to one end, away from the pull part, of the pull rod through a rocking connecting rod. The vertical surfaces can stack coal in the coal bunker body towards the inclined surface, so that adhered surfaces of coal are reduced, and therefore, the pull part pulls the loosening parts to loosen coal bonded on the inner wall of the coal bunker body, mobility of coal is restored, and boiler operation caused by coal blockage is prevented from pulling.

Description

technical field

[0001] The invention belongs to the field of power generation equipment, in particular to a coal bunker for preventing high-moisture coal from caking. Background technique

[0002] The moisture content of coal has a great influence on the fluidity of coal. Within a certain range, the higher the moisture content of coal, the greater the viscosity and the worse the fluidity. Circulating fluidized bed boilers generally require the coal moisture to be controlled between 6% and 8%. When the coal moisture exceeds 8%, the viscosity will increase greatly; when the coal moisture exceeds 10%, the coal fluidity will reduce the viscosity. Increased, it is easy to accumulate on the wall of the coal bunker due to adhesion and adsorption. Coal-based thermal power generation is mainly washed and mixed coal. The moisture content of this coal type is about 14%. After blending with other coal types, the boiler will carry out mixed combustion. After the proportioning, the moist...
