A solid-state slag removal pulverized coal furnace

Abstract

The invention discloses a solid-state slagging pulverized coal furnace, which includes a bottom frame, a primary coal powder conveying system, a combustion furnace, a thermoelectric converter and a control box. The bottom frame is provided with a bracket and a supporting plate. On the top of the bracket, the primary pulverized coal conveying system is arranged on the supporting plate, the thermoelectric converter is arranged on one side of the combustion furnace, the control box is arranged on the supporting plate, and the primary pulverized coal conveying system includes coal Material shield, coal blower and transmission combination, the coal blower includes end conical air collector, drum punching coal sucker and blowing impeller group, one end of the drum punching coal sucker is equipped with a fixed frame, and the fixed frame is provided with a turning hole. The invention adopts the reverse action principle of "Peltier effect", utilizes the high-temperature slag in the pulverized coal furnace and the external force difference to generate power to drive the turntable at the bottom of the coal furnace, realizes slag discharge, pulverized coal rolling side suction air delivery mechanism, and optimizes the traditional process feed.

Description

technical field [0001] The invention relates to the technical field of fuel energy saving, in particular to a solid-state slag removal pulverized coal furnace. Background technique [0002] The solid-state slag discharge pulverized coal furnace is a boiler that uses solid fuel and discharges coal slag after combustion. Usually, the pulverized coal furnace will be equipped with a separate wind mill pulverized coal conveying system. It is cut and broken into coal powder and transported to the boiler by wind force. At the same time, a large amount of water is usually used to continuously cool the coal slag before discharging the coal slag. The above methods have the following defects: 1. The wind mill pulverized coal conveying system is divided into feeding, filtering, returning and recycling. The feeding process has many processes and complex structure, among which the filtering effect is poor, and large particles of coal are easy to enter the furnace with the wind, and then i...

[0002] The solid-state slag discharge pulverized coal furnace is a boiler that uses solid fuel and discharges coal slag after combustion. Usually, the pulverized coal furnace will be equipped with a separate wind mill pulverized coal conveying system. It is cut and broken into coal powder and transported to the boiler by wind force. At the same time, a large amount of water is usually used to continuously cool the coal slag before discharging the coal slag. The above methods have the following defects: 1. The wind mill pulverized coal conveying system is divided into feeding, filtering, returning and recycling. The feeding process has many processes and complex structure, among which the filtering effect is poor, and large particles of coal are easy to enter the furnace with the wind, and then it is easy to produce large particles of coal slag after combustion, which will also lead to incomplete combustion. 2. Continuous coal slag cooling is adopted Water cooling, which will not only cause a lot of waste of water resources, but also cause the heat loss of coal slag

3. The control requirements for the flame temperature of the slagging furnace are relatively high. Too high or too low temperature will cause the slag to coke and stick to the furnace, making slag removal difficult. Therefore, the present invention provides a solid-state slagging pulverized coal furnace
