Description

The twin furnace hot-water boiler

Technical field

The utility model relates to a kind of twin furnace hot-water boiler, belongs to the coal normal-pressure hot-water boiler that looses.

Background technology

At present, most boilers are single burner hearth, during coal combustion because the air feed deficiency, coal can not fully burn, a large amount of volatile matters of overflowing are hanging down under the condition of furnace temperature and anoxic, decompose and be cracked into fine carbon black particle to enter chimney with air-flow, form " over-emitting black exhaust ", this not only wastes energy, and serious environment pollution.For addressing this problem, general all afterbodys in the combustion chamber add various dedusters, invest very greatly, but effect is not very good, and the secondary pollution problem is arranged again after the dedusting.In addition, coal gasification combustion also is a kind of dust collection method of pursuing at present, but this method is strict to ature of coal, is difficult to generally promote.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of twin furnace hot-water boiler is provided, the carbon black particle that it volatilizes in the time of can making coal combustion enters another burner hearth secondary and fully burns, and then has solved " over-emitting black exhaust " problem, and it does not need to set up cleaner, be applicable to various fire coals, improve heat utilization efficiency effectively, saved the energy, rational in infrastructure, cost is low, and environmental pollution is little.

The purpose of this utility model is to realize like this, it comprises drum, flue tube, chimney, burner hearth, water fire grate, firing door, air door, its drum below has been arranged side by side left and right two burner hearths, left and right burner hearth front end is provided with firing door and air door, the water fire grate is equipped with in inside, and water fire grate top is left and right combustion chamber, and the below is left and right air compartment, the rear portion of left and right air compartment is provided with horizontal baffle and vertical clapboard, forms left smoke chamber and right smoke chamber; Be respectively equipped with left and right flue door on the horizontal baffle of left and right smoke chamber, it communicates with left and right combustion chamber respectively; Be respectively equipped with left and right gas door on the vertical clapboard of left and right smoke chamber, it communicates with left and right air compartment respectively, and left and right flue door and left and right gas door place are equipped with two-way panel turnover switch; Communicate with each other by intercommunicating pore between left and right smoke chamber; The front upper part of left and right combustion chamber is provided with left and right cigarette hole, communicates with flue tube in the drum, and two-way cigarette hole panel turnover switch is equipped with at place, left and right cigarette hole.

Compared with prior art, advantage of the present utility model is:

1, because two burner hearths are arranged, can replace coal, the unburned volatile matter in the burner hearth of coal is introduced another burner hearth carry out second-time burning, therefore, structure is more reasonable, and is fully coal-fired, over-emitting black exhaust not, fuel savings 20-30%, low in the pollution of the environment;

2, be applicable to the fire coal of various quality, so applied range is convenient to promote the use of;

3, do not need to set up cleaner, significantly reduced fund input, reduced production cost, do not have the secondary pollution problem.

The specific embodiment

Below in conjunction with drawings and Examples in detail the utility model is described in detail.

The utility model drum 2 belows have been arranged side by side left and right two

burner hearths

25,24; Left and

right burner hearth

25,24 front ends are provided with firing door 15 and air door 17, water fire grate 13 is equipped with in inside, water fire grate 13 tops are left and

right combustion chamber

20,14, the below is left and right air compartment 18,12, the rear portion of left and right air compartment 18,12 is provided with horizontal baffle 5 and vertical clapboard 11, forms left smoke chamber 22 and right smoke chamber 10; Be respectively equipped with left and right flue door 23,6 on the horizontal baffle 5 of left and

right smoke chamber

22,10, it communicates with left and

right combustion chamber

20,14 respectively; Be respectively equipped with left and

right gas door

21,9 on the vertical clapboard 11 of left and

right smoke chamber

22,10, it communicates with left and right air compartment 18,12 respectively, and left and right flue door 23,6 and left and

right gas door

21,9 places are equipped with two-way panel turnover switch 7; 22,10 of left and right smoke chambers communicate with each other by intercommunicating pore 8; The front upper part of left and

right combustion chamber

20,14 is provided with left and right cigarette hole 19,16, communicates with flue tube 3 in the drum 2, and two-way cigarette hole panel turnover switch 1 is equipped with at 19,16 places, left and right cigarette hole.

During the utility model work, left and

right burner hearth

25,24 can replace coal.Such as, during coal, the coals in the right bearth 24 are in the coke high-temp combustion stage in left hearth 25.Open left flue door 23 and right gas door 9 by two-way panel turnover switch 7 this moment, closes left gas door 21 and right flue door 6, opens right cigarette hole 16 by two-way cigarette hole reprint switch 1, closes left cigarette hole 19.Like this, the flue gas of the unburned volatile carbon black track producing particle that produces in the combustion chamber, a left side 20 is under chimney 4 suction functions, enter in the right air compartment 12 by left flue door 23, intercommunicating pore 8, right gas door 9, upwards by the coke layer fully burning once more of high-temp combustion, the hot gas in the right combustion chamber 14 enters flue tube 3 by right cigarette hole 16 and discharges from chimney 4.This process needs about one hour altogether, and this moment, left hearth 25 interior coals were in the coke high-temp combustion stage.Then, open right flue door 6 and left gas door 21, close left flue door 23 and right gas door 9, open left cigarette hole 19, close right cigarette hole 16 by two-way cigarette hole panel turnover switch 1 by two-way panel turnover switch 7.Like this, opposite with said process, the flue gas in the right combustion chamber 14 enters in the left air compartment 18 by right flue door 6, intercommunicating pore 8, left gas door 21, through fully entering flue tube 3 from chimney 4 discharges by left cigarette hole 19 after the burning.So come and go alternation, realize coal-fired abundant burning.

The utility model can be used for heat supply water, heating, bathing etc., and is easy to use, economizes on coal and pollution-free.
