Summary of the invention:

The purpose of this utility model is to provide a kind of simple in structure, with low cost, safe and reliable, easy installation and removal, also can enter a kind of non-pressure boiler device of maintenance in the boiler body.The purpose of this utility model is achieved in that it comprises the outer heat exchange housing of body of heater, the heat radiation smoke exhaust pipe, water inlet, the boiler jacket body, atmospheric communicating pipe, swan neck in the heat radiation, the 3rd layer of heated body, the 3rd layer of string water pipe, heat radiation is swan neck down, water, flue outlet, the flue connecting box, delivery port, second layer string water tubule, string water extra heavy pipe, manage in the string water, the furnace enclosure body, fire door, the ashes chamber, second layer heated body, the ground floor heated body, the burner hearth heating tube, water return outlet, the internal furnace body, circular radiator, the smoking deferent, motor, blower fan.The boiler jacket body is above the furnace enclosure body, boiler jacket body and furnace enclosure body are welded to connect, there is water in space in the boiler jacket body, swan neck in the heat radiation, the 3rd layer of heated body, the 3rd layer of string water pipe, heat radiation is swan neck down, water, flue outlet, the flue connecting box, delivery port, second layer string water tubule, string water extra heavy pipe, manage in the string water, the furnace enclosure body, fire door, the ashes chamber, second layer heated body, the ground floor heated body is in water, there is the 3rd layer of heated body second layer heated body top, there is the ground floor heated body below, the flue outlet of second layer heated body and flue connecting box connect and compose and being connected of the 3rd layer of heated body, second layer heated body and ground floor heated body are welded to connect, the circular radiator top and the swan neck down that dispels the heat, the below is connected with the burner hearth heating tube.Have in the circular radiator in the string water and manage.Have in the string water on the heat radiation smoke exhaust pipe in the outer heat exchange housing of body of heater and manage.Have in the string water on the heat radiation smoke exhaust pipe 2 in the outer heat exchange housing 1 of body of heater and manage 16.The utility model has the advantages that: simple in structure, with low cost, safe and reliable.With common diffusing coal is fuel, uses the reverse burning of double-layer grate, and raw coal is carried out the preheating destructive distillation, and oxygen carbon after forming the destructive distillation coal and transforming and half coal vapour make combustible and volatilization powder high temperature after-flame in the coal that looses in the indoor integrated burning of grate firing up and down.Combustion temperature in hearth is higher 170～200 ℃ than former diffusing coal temperature, can save energy 30～35% on year-on-year basis.Adopt nature and air inducing, do not need air blast, the water treatment flue dust is arranged in addition.Move dustless, noiselessness.Water temperature can maintain the temperature at 60～70 ℃ in the stove under the non-stop-machine duty of operation, and backwater is at 45～55 ℃.The utility model boiler body heating surface is 3～4 times of normal boiler.Other same model stove of hot water Capacity Ratio is big 5 times.But the boiler replace tubes is repaired.

Description of drawings:

Fig. 1 is the three-dimensional section principle schematic of the utility model syndeton; Fig. 2 is the utility model second layer heated body and ground floor heated body syndeton principle schematic perspective view; Fig. 3 is outer heat exchange housing section of the utility model body of heater and circular radiator section syndeton principle schematic perspective view.The utility model piece number explanation: the outer heat exchange housing of 1-body of heater, 2-heat radiation smoke exhaust pipe, 3-water inlet, 5-atmospheric communicating pipe, 23-water return outlet, 24-internal furnace body, 26-smoking deferent, 27-motor, 28-blower fan.

The specific embodiment:

Boiler jacket body 4 is above furnace enclosure body 17, boiler jacket body 4 is welded to connect with furnace enclosure body 17, there is water 10 in space in boiler jacket body 4, swan neck 6 in the heat radiation, the 3rd layer of heated body 7, the 3rd layer of string water pipe 8, heat radiation is swan neck 9 down, water 10, flue outlet 11, flue connecting box 12, delivery port 13, second layer string water tubule 14, string water extra heavy pipe 15, manage 16 in the string water, furnace enclosure body 17, fire door 18, ashes chamber 19, second layer heated body 20, ground floor heated body 21 is in water 10, there is the 3rd layer of heated body 7 second layer heated body 20 tops, there is ground floor heated body 21 below, the flue outlet 11 of second layer heated body 20 and flue connecting box 12 connect and compose and being connected of the 3rd layer of heated body 7, second layer heated body 20 is welded to connect with ground floor heated body 21, circular radiator 25 tops and the swan neck 9 down that dispels the heat, the below is connected with burner hearth heating tube 22.Have in the circular radiator 25 in the string water and manage 16.Have in the string water on the heat radiation smoke exhaust pipe 2 in the outer heat exchange housing 1 of body of heater and manage 16.Pipe all is the pipe hollow, that two ends are not sealed in the 3rd layer of string water pipe, second layer string water tubule, the string water, and they are to be welded in the inner chamber of the 3rd layer of heated body, second layer heated body, ground floor heated body, and their inner chamber is walked flame.The pipe turnover in the 3rd layer of string water pipe, second layer string water tubule, string water of water in the body of heater, circulation heating.The utility model course of work: after the diffusing coal in the fire door is burned, flame and cigarette make progress away, through the inner chamber of ground floor heated body, second layer heated body, the 3rd layer of heated body go out to flue outlet through the flue connecting box to heat radiation down the cavity in swan neck, the circular radiator, smoking deferent again through the inner chamber of blower fan, after the chimney on the heat radiation smoke exhaust pipe is discharged flue gas to the heat radiation smoke exhaust pipe.All be water between the pipe in the outer heat exchange housing of body of heater and the outer heat exchange housing of body of heater, circular radiator and the string water.In the process that flame constantly makes progress away, water on one point, the heating of a bit, the mutual promotion that cold water and hot water constantly replace, constantly string is moving in the boiler jacket body for water, water quickens in the pipe to flow in the 3rd layer of string water pipe, in the second layer string water tubule, in the string water, the circulation of quickening, temperature is also in continuous rising, and is too high as temperature, then run away through atmospheric communicating pipe (being safety valve), pressure in the boiler is 0.1MPa, so it is a pressure-less boiler, and blast never.Hot water has arrived the user through delivery port.Water pipe through the user has arrived water return outlet again, re-injects in the boiler jacket body, participates in thermal cycle again.Water is not much of that, adds water through water inlet.If fall in the sensation stove water or 3 years after, suspection be pipe broken or pipe on incrustation scale many, boiler thermal output is low, then the water in the boiler jacket body is bled off, the maintenance personal enters into the inside from meeting mouth, and bad parts such as pipe are changed.Atmospheric communicating pipe boiler jacket body top any old place can.Water inlet, delivery port, water return outlet can at boiler jacket body top any old place.
