Abstract

The utility model relates to a pressure-free screw flue boiler which is composed of a boiler body [4], a flue [8] and a burning chamber [14]. The utility model is characterized in that the inner wall of the upper side of the burning chamber [14] is provided with a brick bracket [12], and the top surface of the burning chamber [14] is provided with a flameproof afterburning brick [11] that is arranged on the brick bracket [12]. The flameproof afterburning brick [11] is provided with a circular fire through hole [13], and the edge of the flameproof afterburning brick [11] is provided with a brick bracket hole [20] of the flameproof afterburning brick. A screw flue [8] in the cylindrical boiler body [4] on the flameproof afterburning brick [11] is welded into a square pipe by an iron plate, and is in a screw spiral body. The lower side of the screw flue [8] and the flameproof afterburning brick [11] are communicated with the burning chamber [14] through the fire through hole [13] and the brick bracket hole [20] of the flameproof afterburning brick. The low position of each layer screw flue [8] on the side wall of the boiler body [4] is provided with an ash removal opening [6]. Since the flue in the boiler body is lengthened, the pressure-free screw flue boiler can fully utilize waste heat of smoke exhausting and reduce heat loss. The pressure-free screw flue boiler burns completely, does not exhausts black smoke, reduces smoke and dust pollution, and is favorable for environment protection. The utility model does not need electric facilities, such as blowers, draught fans, etc., and saves electric charge.

Description

There is not the spiral of pressure flue boiler

Technical field

The utility model belongs to unit, family's heating, heats up water and use miniature boiler, is a kind of spiral flue boiler.

Background technology

Pressure-less boiler of the prior art, the flue in the body of heater is shorter relatively, can not make full use of the waste heat of flue, and generally all is equipped with electronic combustion-supporting equipment such as air blast, air-introduced machine or circulating pump or helps recycle unit.Shortcomings such as there is noise pollution at the peak times of power consumption heatings peak of also need hiding during work, the electricity charge are more.

Summary of the invention

The purpose of this utility model is to avoid above-mentioned weak point of the prior art, provide and adopt spiral spirally flue in a kind of body of heater, the nothing that fully absorbs smoke discharging residual heat is pressed spiral flue boiler, reduce heat loss, improve the thermal efficiency, reduce smoke contamination, during work without non-electric power economized boilers of electronic combustion-supporting facility such as air blast, air-introduced machines.

The purpose of this utility model realizes by following measure:

A kind of nothing is pressed spiral flue boiler, be by body of heater 4, flue 8, combustion chamber 14, fire-resistant afterburning brick 11 is formed, it is characterized in that ashes thorax 19 is arranged at cylindrical furnace 4 bottoms, it above the ashes thorax 19 combustion chamber 14, on 14 upper inside walls of combustion chamber, be installed with 6 brick-supporting racks 12, combustion chamber 14 end faces have fire-resistant afterburning brick 11, be installed on the brick-supporting rack 12, be evenly distributed with 7 circular fire-pulling holes 13 on the fire-resistant afterburning brick 11, be evenly distributed with 6 fire-resistant afterburning brick brick-supporting rack holes 20 on fire-resistant afterburning brick 11 edges, spiral flue 8 above the fire-resistant afterburning brick 11 in the cylindrical furnace 4 is to be welded into the four directions pipe by iron plate, convolution in the shape of a spiral, spiral flue 8 downsides in the body of heater and fire-resistant afterburning brick 11 are by fire-pulling hole 13, fire-resistant afterburning brick bracket hole 20 and combustion chamber 14 communicate, spiral flue 8 upside exhaust openings 1 in the body of heater are cylindrical, bottom lock, spiral flue 8 in the body of heater communicates with cylindrical exhaust opening 1 from the side in the upper end, surface helix flue 8 opens between top and the last layer spiral flue 8 on the fire-resistant afterburning brick 11 resume combustion pipe 10, each helical layer flue 8 lower has cleaning door 6 on body of heater 4 sidewalls, there is dust-exhausting port 7 cleaning door 6 bottom surfaces, fire-resistant sealing brick 5 is arranged between cleaning door 6 and the spiral flue, delivery port 3 and thermometer mouth 2 are arranged at body of heater 4 tops, and body of heater 4 downsides have water inlet pipe 16, fire door 15 and ash door 18.

The utility model compared with prior art has following beneficial effect:

1, the lengthening of the flue in the body of heater can make full use of smoke discharging residual heat, reduces heat loss, improves the thermal efficiency, is sparing in the use of coal.

2, sufficient combustion is not arranged black smoke, reduces smoke contamination, helps environmental protection.

3, need not use air blast, electronic facility such as air-introduced machine, the operation noiselessness is saved the electricity charge, and the peak times of power consumption heating need not be hided peak times of power consumption.
