Abstract

The invention belongs to the technical field of combustion mechanisms, particularly relates to a coal-saving combustion mechanism for an industrial boiler, and aims to solve the problems that large-particle briquettes are easy to generate in the combustion process of existing coal cinder, and the combustion and utilization of the coal cinder are greatly not facilitated. The coal-saving combustion mechanism for the industrial boiler comprises a box body, and the outer wall of the top of the box body is fixedly connected with a feeding channel; and a motor is fixedly connected to the outer wall of the top of the box body, a rotating shaft is fixedly connected to the bottom of the motor, and a crushing mechanism is arranged in the box body. By arranging a first combustion box and a second combustion box, pulverized coal can be subjected to multi-stage combustion treatment, the combustion utilization rate of the coal is increased, an oxygen supply mechanism arranged in the first combustion box can supply oxygen to the interior of the first combustion box in time, and the coal combustion efficiency is further improved; and by arranging a heat outlet at the top of the first combustion box, heat in the coal combustion process can be conveniently collected, and the utilization efficiency is high.

Description

technical field [0001] The invention relates to the technical field of combustion mechanisms, in particular to a coal-saving combustion mechanism for industrial boilers. Background technique [0002] There are two types of industrial boiler products. One is steam, which is used for power generation or gas supply. The boiler is a kind of energy conversion equipment. Industrial boilers are still mostly coal-fired. The energy input to the boiler includes chemical energy in the fuel, Electric energy, the boiler outputs steam with certain heat energy, high-temperature water or organic heat carrier, the hot water or steam generated in the boiler can directly provide the required heat energy for industrial production and people's life, and can also be converted into mechanical energy through a steam power device, or regenerated The boiler that converts mechanical energy into electrical energy through a generator and provides hot water is called a hot water boiler, which is mainly u...
