Description

Coal feeder for boiler

Technical Field

The invention relates to a coal feeder, in particular to a coal feeder for a boiler, and belongs to the technical field of coal feeders.

Background

Coal, called coal for short, is ancient plant remains, is buried under the stratum, and acts under the pressure and temperature condition of air isolated by the crust, so that carbonized fossil minerals are produced, and are mainly exploited by human beings to be used as fuels.

Coal is used for modern industries, namely heavy industry and light industry; the coal is called as the real grain of industry and is one of the main energy sources used in the human world since the eighteenth century because various industrial departments need to consume a certain amount of coal to a certain extent regardless of the energy industry, the metallurgical industry, the chemical industry and the mechanical industry, the light textile industry, the food industry and the transportation industry.

The boiler is an energy conversion device, the energy input to the boiler comprises chemical energy and electric energy in fuel, and the boiler outputs steam, high-temperature water or an organic heat carrier with certain heat energy.

The boiler is a water container heated on fire, a furnace is a place where fuel is combusted, and the boiler comprises a boiler and a furnace. The hot water or steam generated in the boiler can directly provide heat energy for industrial production and people life, and can also be converted into mechanical energy through a steam power device, or the mechanical energy is converted into electric energy through a generator. The boiler for supplying hot water is called a hot water boiler, is mainly used for life, and has a small amount of application in industrial production.

The boiler for generating steam is called as a steam boiler, often called as a boiler for short, and is widely used for thermal power stations, ships, locomotives and industrial and mining enterprises.

Coal is carried through the drive belt often for boiler among the prior art when using, but the input still needs the manual work to carry out the material loading, consequently it is not convenient, and adopt spiral feeding to appear the problem of blocking again easily, secondly among the prior art batcher can't carry out the regulation of degree of depth in the feed, can only drop into same position department, lead to the input that can't carry out different positions coal and reduce the combustion rate, still need carry out artifical coal that distributes and waste time and energy relatively, for this design a boiler with coal feeder optimize above-mentioned problem.
