Abstract
The utility model relates to a railway passenger car coal-fired heating boiler to deal with the problems in the prior art technology such as inadequate combustion, large amounts of dust emission and frequent coal filling. The utility model comprises a boiler housing and an internal tank, wherein a fire grate and a chimney are arranged in the internal tank. The utility model is characterized in that a circular water jacket is formed between the housing and the internal tank, a coal storage chamber and a closed water tank are positioned in the internal tank, and a vertically fixed fire tube is arranged in the water tank. As the coal storage chamber added in the utility model, a large amount of coal can be filled in once and the number of coal filling is greatly reduced and the laboring intensity is reduced. In addition, after the coal undergoes complete combustion in a firebox, the ash drops into a dust chamber. The flue gas after combustion and the gas produced by preheating of coal in the coal storage chamber enters into the fire tube to burn more completely under the action of wind from the coal filling door and the door of the dust chamber. The dust after secondary combustion is discharged from the chimney communicated with the fire tube, thus the amount of dust emission is decreased dramatically.
Description
Technical field
The utility model relates to the coal-fired heating boiler of a kind of passenger train, specifically to having a kind of improvement of the coal-fired heating boiler of passenger train now.
Background technology
The coal-fired heating boiler that existing passenger train uses is to belong to the in line heating boiler of waterpipe type, and coal is directly in the combustion chamber internal combustion, and the water pipe of top, combustion chamber is heated.Because the burning of the boiler smoke of this structure is insufficient and discharge capacity is very big, and directly is discharged in the atmosphere, therefore do not possess environmental-protecting performance, and labor intensity of operating staff is big, coal is frequent.
Summary of the invention
The utility model is in order to solve technical problems such as the coal that prior art exists is frequent, burning is insufficient, smoke discharge amount is big, seriously polluted.
In order to solve the problems of the technologies described above, the utility model comprises boiler jacket and inner bag, is provided with fire grate and chimney in the inner bag, it is characterized in that: be formed with cyclic water jacket between shell and the inner bag, in inner bag, also be provided with the water tank of coal storeroom and sealing, be provided with the fire tube of vertical installation in the water tank.
The upper end of described fire tube is inserted in the chimney, and the fire tube below is provided with the guide plate that is obliquely installed, and a combustion chamber is formed on guide plate and water tank bottom, and insert in the combustion chamber lower end of fire tube.
The utlity model has following advantage and good effect: because the utility model has increased coal storeroom, therefore can once add a large amount of coals, coal flows downward under the effect of gravity, has realized automatic combustion, reduce the coal number of times widely, reduced labour intensity; In addition, the coal that enters the combustion chamber is through after the completing combustion, coal ash falls into dirt pocket, the coal gas that the coal of gas fume after burning and coal storeroom produces after preheating, under the wind action that firing door and ash door are blown into, enter in the fire tube and burn more completely again, flue dust after the second-time burning from chimney that fire tube communicates in discharge, thereby make smoke discharge amount obviously reduce, compliance with environmental protection requirements.
