Preferably, some smoke box water pipes be connected with boiler intracavity are provided with the smoke box inwall place of junction, combustion chamber.
Preferably, be provided with some short pieces be communicated with boiler intracavity by external pipe near fire door inwall place inside described fire door, it is higher that smoke box and fire door place accept flame energy, is provided with pipeline herein and at utmost can utilizes heat.
Preferably, described inner conduit is 4 groups, and about described combustion chamber, two groups vertically arrange, and is that one end is inclined upwardly setting at upper and lower two groups, vertically and be obliquely installed can make water be heated after convection circulation up and down.
Preferably, boiler water filling port is positioned at upper boiler, and top water filling can make water first through the preheating of smoke pipe, more makes full use of waste heat.
Usefulness of the present utility model is that the heat heating surface area that many water pipe structures make combustion gas in combustion chamber and smoke pipe increases, Energy harvesting for the direct-fired fire door of combustion gas and flue is more scientific and reasonable, make water forced circulation outside combustion chamber, the water of the identical initial temperature of heating equal in quality, save combustion gas more than 5%, heat time shortens, utilization rate and efficiency all have lifting, and water pipe can adopt with miscellaneous part connected mode and welds various ways such as casting, reduce difficulty of processing, save production cost.

Detailed description of the invention
Embodiment one:
The structural representation of embodiment 1 and section of combustion chamber structural representation as depicted in figs. 1 and 2, a kind of gas fired-boiler comprises boiler shell, be positioned at the combustion chamber 1 below boiler internal, the fire door 3 just right with combustion chamber, the smoke box 2 of three built-in return structures and the smoke pipe 9 be communicated with smoke box, it is boiler intracavity 8 above combustion chamber 1, in combustion chamber 1, the inner place near inwall is provided with 4 groups of inner conduits 6, the left and right sides, combustion chamber 1 water pipe is vertically placed, be that one end is inclined upwardly setting in upper and lower both sides, inner conduit 6 can make water and combustion chamber contact area increase when not affecting gas flame normal combustion, improve heat transfer efficiency, smoke box 2 is provided with some smoke box water pipes 6 in the place near combustion chamber 1 end, the inwall of fire door 3 is provided with many short pieces 5, short piece 5 is communicated with boiler intracavity 8 by pipeline outside boiler, the direct heating of flame can be accepted, end in combustion chamber 1 of the flame of fuel gas buring and fire door 3 place have very high heat, arrange at this heat that water pipe effectively can utilize flame envelope part.The present embodiment water circulation is: combustion chamber is heated, the water convection circulation in inner conduit; Near combustion chamber, water temperature improves, and forms water circulation at boiler intracavity.The endless form of this embodiment is Natural Circulation, relies on the heat temperature raising of water to realize convection current, increases than traditional combustion chamber heating surface (area) (HS.
Embodiment two:
If Fig. 2 is the utility model embodiment two section of combustion chamber structural representation, compared with embodiment 1, one deck sleeve pipe 4 is added outside combustion chamber 1, be provided with between combustion chamber 1 and sleeve pipe 4 some by inner conduit 7 and and inner conduit 7 be combined to form the cannula cavity 41 of continuous water channel, being opened by the two ends baffle for separating of one or more water pipes among inner conduit 7 specifically makes it be connected according to pre-designed circuit, so just forms water channel with cannula cavity 41.One end of water channel is communicated with described boiler intracavity 8, and the other end is communicated with boiler delivery port by the outlet pipe 51 be located on affiliated sleeve pipe.The endless form of the present embodiment water is: water enters boiler intracavity 8 and carries out preheating at top flue 9 place after entering the water inlet on top, then the water channel formed by sleeve pipe 4, combustion chamber 1, water-stop sheet 41 and inner conduit 7 through the water of preheating is flowed, flowed out from delivery port by outlet pipe 51 after chamber wall circulation, complete whole circulation.This embodiment adopts forced circulation, make water in combustion chamber, keep flowing as much as possible, one whole boiler water to have been heated releasing different from tradition, heating energy through preheating and chamber wall keeps continuously hot water to flow out, substantially increase boiler efficiency, such as initial temperature is that 1 ton of water of 18 DEG C is heated to 42 DEG C, and plain cylindrical furnace needs the combustion gas of 4 ~ 5 cubic metres, and the boiler using the present embodiment to provide only needs the combustion gas of about 3 cubic metres, Be very effective.
The utility model can increase the heating surface (area) (HS of water effectively, the flue that rear end, Appropriate application combustion chamber temperature is higher and fire door heat, water is convection circulation in water pipe, after improvement, forced circulation makes current more scientific and reasonable, effectively can transmit temperature, the utilization rate of combustion gas can be made effectively to be promoted, simultaneously because water pipe adopts multiple processing mode, reduce production cost.
