Detailed description of the invention
Below in conjunction with specific embodiment, this utility model is expanded on further, it should be appreciated that these embodiments are merely to illustrate this
Utility model rather than limit scope of the present utility model.In addition, it is to be understood that reading the content that this utility model is lectured
Afterwards, this utility model can be made various changes or modifications by those skilled in the art, and these equivalent form of values also fall within application
Appended claims limited range.
Seeing Fig. 1 is this utility model structural representation, and this structure one biomass hot water boiler, it includes body of heater, stove
Body includes the burner hearth 5 being arranged in inner water sleeve 15, and body of heater is arranged on base 12, and bottom of furnace body side is provided with secondary air channel
11, primary air piping 13, described secondary is in charge of, primary air piping 13 is connected with aerator by air preheater, inner water sleeve 15 peripheral hardware
Being equipped with outer water jacket 14, outer water jacket 14 top and upper right side are respectively arranged with row steam hole 1, apopore 2, and outer water jacket 14 lower right side sets
Being equipped with inlet opening 19, burner hearth 5 inner bottom part is provided with fire grate segment 10, is provided with secondary air separating pipe arrangement vertically near burner hearth 5 inwall
8, secondary air hole 7 is distributed on secondary air separating pipe arrangement 8, furnace body outer wall offers firedoor hole 9, and firedoor hole 9 is connected with charging hole 6,
Burner hearth 5 is obliquely above provided with horizontal water tube 3, and horizontal water tube 3 is provided above secondary furnace 4, and the horizontal side of secondary furnace 4 connects fall
Dirt room 23, dust-settling compartment 23 periphery is provided with inner water sleeve 15, is provided with smoke baffle plate 16, is provided with below dust-settling compartment 23 in dust-settling compartment 23
Triple-travel smoke pipe 17, triple-travel smoke pipe 17 is gradually reduced from the flue gas circulation area of every stroke smoke pipe of smoke inlet to outlet flue,
The end of triple-travel smoke pipe 17 is connected to venthole 18, and venthole 18 is connected with air-introduced machine 20, air-introduced machine 20 and Water-tight dust catcher
21 connect, and Water-tight dust catcher 21 end connects chimney 22.
Boiler combustion part is made up of clinker area, solid combustion district, gas combustion district from down to up.Solid combustion district makes pressure
Briquette fuel primary combustion on fire grate segment 10, produces a large amount of fuel gas, and fuel gas is near fire grate segment 10 superjacent air space
Burn smoothly in the case of being equipped with enough secondary wind in gas combustion district, secondary wind control on secondary air separating pipe arrangement 8, is distributed, permissible
Increase burning insufficient material oxygen in air to be combined, make burning more abundant, improve efficiency of combustion, it is to avoid black smoke produces.
High-temperature flue gas is first with the horizontal water tube 3 that relatively low velocity transversal flow is staggered in arrangement, subsequently into dust-settling compartment 23, and a large amount of flying dusts herein
Stopping due to action of gravity, flue gas enters triple-travel smoke pipe 17 subsequently, and every stroke fire tube flue gas circulation area is gradually reduced, and makes
Flue gas washes away fire tube with of a relatively high speed all the time.
First air and secondary wind air flow rate proportioning are 4:6, and so purpose of distribution is: First air makes fuel in solid phase combustion district
Low temperature half gasification, and combustion, effectively reduces burner hearth 5 slagging scorification phenomenon and produces, and secondary wind makes volatile matter at the whole after-flame in gas combustion district.
Secondary wind blows to burner hearth 5 at a certain angle from secondary air channel 11, forms swirl type air velocity distribution, so can make combustion in burner hearth 5
The flame that makes a fire is drawn close to centre, improves flame temperature, and the most also prolongation flame is in burner hearth 5 time of staying, abundant to charcoal and volatile matter
Burning plays an important role.
High-temperature flue gas is with 3～5m/s speed transversal flow stagger arrangement horizontal water tubes 3, under effectively preventing a large amount of flying dust from entering with flue gas
One-level heat-absorbent surface, simultaneously because flue-gas temperature is higher, horizontal water tube 3 absorbs a part of radiations heat energy, and flue gas is with 14～16m/s afterwards
Speed flows through triple-travel smoke pipe 17, has the most both ensured the caloric receptivity of boiler, simultaneously because flue gas is shorter at cigarette intraductal retention time,
Can effectively prevent alkali metal ash from separating out.Apparatus structure is simple, and fuel burns rationally, and boiler combustion efficiency is high, will not produce dense black
Cigarette, pollutes little, and fuel combustion can maximally utilize.
