Problems solved by technology

Traditional boiler coal is medium coal, coal slime, and coal gangue. Due to the complex environment, weather and many other factors, when the coal entering the boiler coal bunker is relatively wet, it often leads to blockage of the coal falling pipe, causing the boiler load to be forced suddenly.

Abstract

The invention discloses a coal feeding device for a boiler. The coal feeding device comprises a combustion chamber, the boiler, a furnace, a feed coal funnel and a coal conveying pipeline; the furnace is arranged in the boiler, the bottom of the furnace is communicated with the combustion chamber, a water tank is arranged between the boiler and the furnace, the combustion chamber is provided with a coal feeding opening, the coal conveying pipeline extending into the combustion chamber is arranged in the coal feeding opening, a propelling screw is installed in the coal conveying pipeline, the end of the propelling screw is connected with a motor, and the upper side of the coal conveying pipeline is provided with the feed coal funnel. According to the coal feeding device for the boiler, fast coal feeding into the combustion chamber can be achieved through the coal conveying pipeline, the scald accidents can be effectively prevented from occurring, the coal feeding quantity and rate can be effectively controlled through a control valve and motor rotation speed regulation, meanwhile, the coal conveying pipeline can be effectively prevented from being blocked through the propelling screw, and the coal feeding effect is improved.

Description

technical field [0001] The invention relates to the technical field of boilers, in particular to a coal feeding device for boilers. Background technique [0002] The coal feeding pipe is a device for feeding coal in industries such as coal, ports, thermal power, coal dump stations, coal washing plants, and coal-fired industrial boilers. The coal feeding pipe generally includes a coal hopper, a downcomer, a diversion trough and other components. Traditional boiler coal is medium coal, coal slime, and coal gangue. Due to the complex environment, weather and many other factors, when the coal entering the boiler coal bunker is relatively wet, it often leads to blockage of the coal falling pipe, causing the boiler load to be forced suddenly. In addition, the traditional coal feeding method is inconvenient to control the amount and rate of coal feeding, and manual feeding increases labor intensity and is prone to burn accidents. Contents of the invention [0003] The purpose o...
