Supply mechanism for oxygen content in industrial boiler

Abstract

The invention discloses an industrial boiler internal oxygen content supply mechanism which comprises a hearth, a furnace opening is formed in the side wall of the hearth, the hearth is internally provided with a supply mechanism body, the supply mechanism body comprises a motor, a combustion disc, a baffle ring piece, an annular bin, an annular rack, a gear, an oxygen supply fan and an inclined air opening, and the motor is fixedly connected into the side wall of the bottom of the inner surface of the hearth; the motor works to enable the combustion disc fixedly connected with the output shaft of the motor to rotate, pulverized coal burns on the combustion disc, the combustion disc rotates to enable the baffle ring piece to rotate, and the baffle ring piece is designed to block a gap between the rotating combustion disc and the inner surface of the hearth. A baffle ring piece rotates to drive a ring rack fixedly connected to the baffle ring piece to rotate so that a gear can rotate, and an oxygen supply fan fixedly connected to the gear rotates so that external air can be blown into the hearth to continuously supply oxygen to the combusted pulverized coal.

Description

technical field [0001] The invention relates to the technical field of industrial boilers, in particular to a supply mechanism for oxygen content in industrial boiler furnaces. Background technique [0002] There are two types of industrial boiler products. One is steam, which is used for power generation or gas supply. For example, chemical fertilizer plants can be vaporized with steam, and coal is used as raw material to synthesize chemical fertilizers. This is a typical industrial boiler. Industrial boilers still use coal as the main component Most, gas-fired waste heat boilers are generally used to recover waste heat. Industrial boilers are common circulating fluidized bed boilers Industrial boilers are important thermal power equipment. [0003] In the prior art, the pulverized coal is usually continuously supplied to the furnace so that the pulverized coal is burned in the furnace, and the air containing oxygen is introduced into the furnace at the same time, but in t...

Problems solved by technology

[0003] In the prior art, the pulverized coal is usually continuously supplied to the furnace so that the pulverized coal is burned in the furnace, and the air containing oxygen is introduced into the furnace at the same time, but in this way, the pulverized coal is easy to cause accumulation in the furnace, thus Make it difficult for pulverized coal to burn fully in the furnace, thereby reducing the combustion efficiency of pulverized coal
