Abstract

The utility model discloses a novel standing smokeless energy-saving boiler, comprising a boiler body (1), a flue (9), a boiler door (10) and a fire sealing door (11); dispersed fire tubes (6) are arranged on the upper part of a combustion chamber (3) in the boiler body (1), and the upper part of the dispersed fire tubes (6) are also connected with a smoke buffering chamber (7) in which a crossly-equipped water cooling pipe (8) is arranged; the utility model is further provided with an air-jetting device and a combustion-supporting device. The side lower end of a steam-producing device is connected with a water-replenishing tank (4-1) by a water-supply pipe (4-2), and the upper end jets the produced steam to the flame above the coal layer in the combustion chamber by a steam jetting pipe (4-4); the combustion-supporting device is composed of a blower (5-1) and a combustion-supporting wind pipe (5-2). The steam-supported combustion plus secondary wind-supported combustion device fully burns the coal in the furnace with a stronger fire behavior, and thus, the thermal efficiency of the boiler is enhanced obviously, saving coal and electricity and with a good smoke and dust eliminating effect. The utility model is suitable for the boilers whose valid thermal efficiency is in the range of 0.02 - 1.4 MW, and is applied to various doped coal, raw coal and mixed coal, with excellent popularization value and very wide application scope.

Description

Novel vertical smoke-less power-saving boiler

Technical field

The utility model relates to a kind of vertical fire coal boiler, relates in particular to a kind of tea and bathes warm three-purpose cooker stove.

Background technology

At present, the most of regional employed vertical fire coal boiler of China is by body of heater, flue, fire door with bank up a fire and constitute, because project organization is simple, ubiquity the intensity of a fire weak, heat up slow, insufficient over-emitting black exhaust that burns, and the thermal efficiency is low to be waited and promptly waste energy and the serious problems of contaminated environment.Though occurring many new methods aspect the vertical boiler improvement, many new type of furnaces also occurred, but still thoroughly do not solved, further improved necessity is arranged.

Summary of the invention

Technical problem to be solved in the utility model is to overcome the defective that existing vertical boiler exists, and provides a kind of and burns that the intensity of a fire is violent, quick heating, sufficient combustion, the thermal efficiency is high and the novel vertical smoke-less power-saving boiler of over-emitting black exhaust not.

Technical problem to be solved in the utility model is realized by following technical scheme: this novel vertical smoke-less power-saving boiler, comprise body of heater, flue, fire door and the door of banking up a fire, its improvements are top, body of heater inner combustion chamber installation distributing fire tube, distributing fire tube top is also connecting the flue gas surge chamber, and horizontal water cooling tube is housed in the flue gas surge chamber; It also is provided with air jet system and auxiliary combustion equipment.

Described novel vertical smoke-less power-saving boiler is characterized in that described dispersion fire tube (6) is the 9-21 root.

Described novel vertical smoke-less power-saving boiler is characterized in that described horizontal water cooling tube is the 2-5 root.

Described novel vertical smoke-less power-saving boiler is characterized in that described auxiliary combustion equipment is made up of blower fan and combustion-supporting airduct.

Described a kind of novel vertical smoke-less power-saving boiler, it is individual to it is characterized in that described combustion-supporting airduct can be established 1-3.

Described novel vertical smoke-less power-saving boiler is characterized in that described spray vapour device is made up of water supply tank, upper hose, steam generation device and steam jet.

Described novel vertical smoke-less power-saving boiler is characterized in that steam jet has 2-4.

Because novel vertical smoke-less power-saving boiler has adopted spray vapour device and auxiliary combustion equipment, the top, combustion chamber is provided with the distributing fire tube, structural designs such as horizontal water cooling tube are housed in the flue gas surge chamber, have increased the heating surface area of boiler water wall greatly, make thermal power transfer more complete; Steam added combustion adds secondary wind auxiliary combustion equipment makes coal more abundant in the burner hearth internal combustion, and the intensity of a fire is more violent, thereby makes boiler thermal output have to significantly improve, the economize on electricity of economizing on coal, and smoke medicining dust-removing effect is good.Be applicable to any type of furnace of available thermal power in the 0.02-1.4MW scope, adapt to all kinds of assorted coals, raw coal, mixed coal, have excellent generalization values, range of application is very extensive.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described in further details:

See also Fig. 1 to shown in Figure 4, this novel vertical smoke-less power-saving boiler comprises body of heater 1, flue 9, fire door 10 and the door 11 of banking up a fire, and distributing fire tube 6 is installed on 3 tops, body of heater 1 inner combustion chamber, disperse fire tube 6 tops also connecting flue gas surge chamber 7, flue gas surge chamber 7 is connected with flue 9.Be provided with manhole 12 in upper of furnace body.Combustion chamber 3 is made up of the boiler inner wall and the distributing fire tube 6 of cylinder type above fire grate 2, and the distributing fire tube can have the 9-21 root.Boiler smoke enters in the flue gas surge chamber 7 by distributing fire tube 6, discharges from flue 9.The horizontal water cooling tube 8 of 3-5 root is housed in the flue gas surge chamber 7, cold water is played heat effect.It also is provided with air jet system and auxiliary combustion equipment.Spray vapour device is made up of water supply tank 4-1, upper hose 4-2, steam generation device 4-3 and steam jet 4-4.The side lower end of steam generation device is connected with water supply tank 4-1 by upper hose 4-2, and the upper end sprays to the steam that produces by steam jet 4-4 the flame of upper end, coal seam in the combustion chamber.Steam jet can have 2-4.Secondary wind auxiliary combustion equipment is made up of blower fan 5-1 and combustion-supporting airduct 5-2, and combustion-supporting airduct can be installed 1-3 around body of heater, and effect can be better.Coal except that giving the heating of stove water, is returned steam generation device 4-3 heating when 3 internal combustion of combustion chamber, the steam of generation constantly enters in the steam jet 4-4, sprays to the flame of top, coal seam; Secondary wind auxiliary combustion equipment also blows to combustion air the flame of top, coal seam by blower fan 5-1 and combustion-supporting airduct 5-2, making small carbon granule reaction in steam, air and the flue gas generate fuel gas such as carbon monoxide, hydrogen fully burns, thereby make that the vertical fire coal boiler reaches really that the intensity of a fire is violent, quick heating, thermal efficiency height, sufficient combustion over-emitting black exhaust not, promptly energy-conservation result of use free from environmental pollution again.
