Abstract

The utility model relates to a novel smokeless energy-saving boiler. The novel smokeless energy-saving boiler has the improvement that a secondary combustion chamber is also connected with the upper side of a primary combustion chamber of a boiler body through a dispersion type heat pipe; a steam generating device is arranged in the primary combustion chamber, one end of the steam generating device is connected with an automatic water supplementing box through a water supply pipe, and the other end of the steam generating device is communicated with a steam storage tank through a connecting pipe. The rear part of the boiler body is provided with a preheating coal hopper. The heating area of a water-cooling wall of the boiler is increased, and the heat efficiency of the boiler is obviously enhanced by the structures such as the secondary combustion chamber, a steam combustion-supporting device, the dispersion type heat pipe, a water-cooled pipe type fire grate, etc., of the utility model. The utility model has the advantages of coal economization, power saving and favorable effects on smoke elimination and dust removal.

Description

Novel smoke-less power-saving boiler

Technical field

The utility model relates to a kind of stove and accessory, relates in particular to a kind of civil heating stove and accessory.

Background technology

At present, the employed vertical fire coal boiler in China the greater part, because it is simple in structure, ubiquity that the intensity of a fire is weak, over-emitting black exhaust when heating up slow, new coal, insufficient over-emitting black exhaust that burns, the thermal efficiency are low etc. had not only wasted energy but also the serious problems of contaminated environment, though many new type of furnaces are also arranged, but still fundamentally do not overcome the above problems.

Summary of the invention

The purpose of this utility model is to overcome the defective of existing vertical fire coal boiler, a kind of novel smoke-less power-saving boiler is provided, be provided with steam auxiliary combustion equipment, distributing heat pipe and two structures such as combustion chamber, the characteristics that make that this stove and accessory has that the intensity of a fire is violent, quick heating, sufficient combustion do not produce black smoke.

Technical problem to be solved in the utility model is realized by following technical scheme: this novel smoke-less power-saving boiler, comprise body of heater 1, flue 7, fire door 8, bank up a fire the door 9, its improvements are also to connect a secondary combustion chamber 6 by distributing heat pipe 5 on the primary zone 3 of body of heater 1, be provided with a steam generation device 4 in the primary zone 3, one end of steam generation device 4 is connected with automatic water supply tank 4-1 by upper hose 4-2, the other end communicates with steam storage tank 4-4 by connecting tube 4-3, and the rear portion of body of heater 1 is provided with preheating coal bunker 10.

Above-mentioned novel smoke-less power-saving boiler at water-cooled pipe type fire grate 2, is equipped with steam jet 4-9 in primary zone 3 and the secondary combustion chamber 6, and steam jet 4-9 divides three layers of setting up and down, at least 2 every layer.

Above-mentioned novel smoke-less power-saving boiler is equipped with on the described preheating coal bunker 10 and covers 10-1.

Above-mentioned novel smoke-less power-saving boiler is equipped with steam control valve 4-5 and 4-6 on connecting tube 4-7 and connecting tube 4-8.

Above-mentioned novel smoke-less power-saving boiler, totally 9 of distributing heat pipes 5.

Above-mentioned novel smoke-less power-saving boiler is provided with manhole 11 and port lid 11-1 at the two ends of the secondary combustion chamber 6 of body of heater 1.

Above-mentioned novel smoke-less power-saving boiler, its water-cooled pipe type fire grate 2 is the 5-9 root.

Structures such as the twice combustion chamber of this type of furnace, steam auxiliary combustion equipment, distributing heat pipe and water-cooled pipe type fire grate have increased the heating surface area of boiler water wall greatly, make the thermal efficiency of boiler have and significantly improve; The flue dust that the preheating coal bunker discharges when making coal significantly reduces.This stove result on trial: stable, safe and reliable, the thermal efficiency is high, the economize on electricity of economizing on coal, smoke medicining dust-removing effect are good.Go for any type of furnace of available thermal power in the 0.02-1.4MW scope, adapt to all types of assorted coals, raw coal, mixed coal, have excellent generalization values, range of application is very extensive.
