Abstract

The invention relates to a coal-fired gasification swirl combustion furnace, a cambered guide wall is arranged in a combustion chamber, the combustion chamber is divided into a front combustion chamber and a rear combustion chamber, a flame passage is arranged at the lower part of the cambered guide wall, the lower parts of the front combustion chamber and the rear combustion chamber are communicated through the flame passage, the front combustion chamber and a hearth are separated through a partition wall, a fire tube is arranged at the lower part of the partition wall, the hearth and the front combustion chamber are communicated through the fire tube, a gas hole is arranged at the top part of the partition wall, an upper end hole and a lower end hole of the gas hole are respectively communicated with the hearth and the front combustion chamber, a slidable cover plate is arranged at the upper end hole of the gas hole, the cover plate is connected with an operating rod, an outlet of the rear combustion chamber is communicated with an inlet of a flue, a water pipe is arranged in the flue, the water pipe is communicated with a water jacket, an outlet of the flue is communicated withan inlet of a dust remover through multiple rows of smoke pipes, and an outlet of the dust remover is communicated with a chimney. The swirl combustion furnace can fully combust the smoke dust in gas, eliminate the phenomenon of short-time dense smoke discharge after coal feeding, and greatly improve the cleanliness of exhaust discharge.

Description

technical field [0001] The invention relates to a coal-fired gasification furnace, in particular to a coal-fired gasification swirl combustion furnace capable of reducing dense smoke discharge. Background technique [0002] In recent years, people have developed a new technology of coal-fired gasifiers in order to reduce the pollution of coal-fired furnaces to the atmosphere. The air is added from top to bottom, and the air is countercurrently moved from bottom to top. Chemical reactions and heat exchange occur between them, thus forming several regions in the gasification chamber, called "layers". That is, the ash layer, oxidation layer, reduction layer, dry distillation layer, and drying layer; the oxidation layer and reduction layer are collectively referred to as the reaction layer, and the carbonization layer and drying layer are collectively referred to as the coal preparation layer. The layers are spatially horizontal and each layer has substantially the same thickne...
