Abstract
The utility model belongs to the field of coal-burning boilers, particularly a smokeless coal-burning boiler capable of inhibiting nitrogen oxides. A preheating dry-distilling chamber (7) of the boiler is communicated with a burning chamber (8) at the lower part of a boiler cavity (5), the connecting position of the upper parts of the two chambers are separated by a heat-exchanging pipe (9) which is arranged at the upper end of a coal-supplying hole (4) and passes through the boiler cavity. The space of the boiler wall is communicated with heat-exchanging pipes which are arranged in the burning chamber and are filled with water. The boiler is a smokeless coal-combustion boiler which has the advantages of simple structure, small size and high thermal efficiency. The boiler can inhibit the generation of the nitrogen oxides.
Description
The utility model belongs to what coal-burning boiler field, particularly be the smokeless coal burning boiler that can suppress nitrogen oxide.
Produce a large amount of black smokes and nitrogen oxide during coal-burning boiler burning at present, efficiency of combustion is low, contaminated environment.95102081.1 patented technology provides a kind of easy coal that can make efficient and suppress the smokeless coal-burning method that nitrogen oxide produces.For promoting this technology as early as possible, the inventor uses this method coal-burning boiler has been done further improvement.
Task of the present utility model provide a kind of simple in structure, volume is little, the thermal efficiency is high, can suppress the smokeless coal burning boiler of nitrogen oxide
Goal of the invention of the present utility model is achieved in that
Design a kind of smokeless coal burning boiler that suppresses nitrogen oxide, boiler outer furnace wall (3) is provided with coal filling hole (4) and chimney (10), form furnace chamber (5) by preheating destructive distillation chamber (7) and combustion chamber (8), heat exchanger tube (9) is housed in it, separate by fire grate (1) and grey slag bucket (6) the furnace chamber bottom, preheating destructive distillation chamber (7) and combustion chamber (8) communicate in furnace chamber (5) bottom, top, two Room intersection is to be separated by the heat exchanger tube (9) that is located at coal filling hole (4) upper end and runs through furnace chamber, the space of furnace wall be distributed in the combustion chamber in water-filled heat exchanger tube communicate.During boiler operatiopn, the coal of preheating destructive distillation chamber and the coal of combustion chamber fuse, after coal adds from coal filling hole, anoxic destructive distillation continuously under the air-tight state of preheating destructive distillation chamber, and constantly enter combustion chambers burn, heated in the heat exchanger tube and the water between furnace wall and furnace chamber, suppressed the discharging of nitrogen oxide simultaneously.
Advantage of the present utility model is:
1. the pipeline because of heat exchanger is not the afterbody that concentrates on the combustion chamber, but is distributed in the combustion chamber, and the space, furnace wall is full of water again, so heat exchange is abundant, thermal efficiency height.
2. the top of preheating destructive distillation chamber and combustion chamber is to separate by the pipeline of heat exchanger, omitted the furnace wall partition, so boiler volume is little, and is simple in structure.
3. preheating destructive distillation chamber and combustion chamber communicate in the furnace chamber bottom, and the top of two Room has pipeline to be separated by again, and preheating destructive distillation chamber is anaerobic condition during boiler operatiopn, therefore can effectively suppress the generation of nitrogen oxide, have protected environment.
Fig. 1: boiler elevational schematic view;
Following examples are described further in conjunction with the accompanying drawings:
Fig. 1 shows a kind of coal-burning boiler that can suppress nitrogen oxide, its furnace chamber 5 is made up of preheating destructive distillation chamber 7 and combustion chamber 8, two Room communicate in the bottom of furnace chamber, and top, two Room intersection is to be separated by the pipeline that is located at coal filling hole 4 upper ends and runs through the heat exchanger 9 of furnace chamber.Coal filling hole 4 is located at the middle part of furnace wall 3, and its underpart is provided with discloses burner 2, so that the coal seam in the mediation furnace chamber.The bottom of boiler is grey slag bucket 6, and it and furnace chamber intersection are provided with fire grate 1, and chimney 10 is equipped with at the top of outer furnace wall, the heat exchanger tube 9 that has been staggered in the combustion chamber, pipeline and furnace wall communicate with space between furnace chamber, are full of water therebetween, be flowing of just what water, pipeline will have certain gradient.Around the bottom of combustion chamber,, refractory insulating layer 11 is housed for protection furnace wall and pipeline.This stove can be done heating stove, also can do boiler.
