Abstract

The utility model discloses a reverse combustion coal-to-gas environmental protection boiler. In the boiler, a coal gas generator is arranged above a fire grate, and a gas storage chamber is arranged below the fire grate; the gas storage chamber is connected with a coal gas ignition chamber by a coal gas channel, and the coal gas ignition chamber is connected with a fire tube of a heat exchange chamber. The boiler is characterized in that the coal gas channel is arranged below the fire grate. Due to the adoption of the reverse combustion boiler structure, the boiler has the advantages of complete burning of fuel, high heat exchange rate of the boiler, little emission of smoke gases and good effects of energy conservation and environmental protection; due to the full consideration of requirements of users, the boiler can be widely applied to heating, water burning and bathing, etc.

Description

The anti-coal that burns of normal pressure changes compression ring guarantor boiler

Affiliated technical field

The utility model relates to a kind of civilian normal pressure gas boiler.

Background technology

At present, the heating of selling on the market, heat up water, bath boiler, common project organization is: body of heater is provided with water jacket samdwich or comb, is provided with ash-falling chamber, fire grate, combustion chamber in the body of heater from down to up successively; Coal-fired directly burning, the problem that this boiler exists is that fuel combustion is insufficient, the particle that floats in the flue gas is more.

Summary of the invention

The utility model provides the anti-coal that burns of a kind of normal pressure to change compression ring and protect boiler, be primarily aimed at that present civilian normal-pressure boiler fuel combustion is insufficient, the thermal efficiency is low, flue gas is big, function singleness shortcoming.By making fire coal be converted into fuel gas and fully burning and to the optimal design of boiler combination property, it is become have the higher thermal efficiency, soot emissions are little, the energy-conservation gas boiler of civilian efficient multi-purpose that function is more complete.

The purpose of this utility model is achieved through the following technical solutions:

Normal pressure is counter to burn coal changes compression ring and protects boiler, be gas generating chamber above the grate, be air storage chamber below the grate, and air storage chamber is by gas passage connection coal gas pilot chamber, and the fire tube of pilot chamber connection heat-exchanging chamber is characterized in that: gas passage be located at grate below.

The fire tube bottom that vertically distributes in the heat-exchanging chamber is provided with the dedusting mouth.

The water jacket of heat-exchanging chamber communicates with the water jacket of gas generating chamber, air storage chamber, coal gas pilot chamber.

The beneficial effects of the utility model are: owing to adopted anti-burning furnace structure to make fuel combustion more abundant, boiler hot exchange rate height, soot emissions are little, and are energy-conservation good with environment protecting; Owing to fully take into account user's demand, the utility model can be widely used in heating, heats up water, bathing, etc. purposes.

Among the figure, 1, air storage chamber, 2, grate, 3, gas generating chamber, 4, gas passage, 5, coal gas pilot chamber, 6, the dedusting mouth, 7, heat-exchanging chamber, 8, air storage chamber, 9, grate, 10, gas generating chamber, 11, the dedusting mouth, 12, heat-exchanging chamber, 13, the coal gas pilot chamber, 14, gas passage.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 the utility model embodiment 1, in the drawings as can be seen, present embodiment is a horizontal boiler, above the grate (2) is gas generating chamber (3), it below the grate air storage chamber (2), air storage chamber laterally connects coal gas pilot chamber (5) by gas passage (4), and pilot chamber connects the fire tube of heat-exchanging chamber (7), it is characterized in that: gas passage be located at grate (2) below.

The fire tube bottom that vertically distributes in the heat-exchanging chamber is provided with dedusting mouth (6).

Fig. 2 is embodiment 2 of the present utility model, and what it was different with embodiment 1 is that body of heater is vertical, and coal gas pilot chamber (13) vertically is connected with heat-exchanging chamber (12) fire tube.

Its operation logic is, during boiler operatiopn, in fire coal, add suitable water or steam, fire coal ignites, regulating air quantity and steam vapour amount makes fire coal be converted into coal gas, coal gas enters after the coal gas pilot chamber, under strong general mood stream impacts, burning forms the power scene of a fire and enters heat exchanger, because the inner fire tube of heat exchanger is longer, has prolonged the time that gas fire stops in heat exchanger, increased combustion intensity, improve the thermal efficiency, thereby realized energy-efficient purpose, reached the purpose that reduces pollutant emission.

Claims

1, the anti-coal that burns of a kind of normal pressure changes compression ring guarantor boiler, above the grate (2,9) is gas generating chamber (3,10), below the grate air storage chamber (1,8), air storage chamber connects coal gas pilot chamber (5,13) by gas passage (4,14), pilot chamber connects the fire tube of heat-exchanging chamber (7,12), it is characterized in that: gas passage (4,14) be located at grate below.

2, the anti-coal that burns of normal pressure according to claim 1 changes compression ring guarantor boiler, and it is characterized in that: the fire tube bottom that vertically distributes in the heat-exchanging chamber is provided with dedusting mouth (6,11).
