Described air intake pre-heating energy-saving boiler, it is characterized in that: described waste heat reservoir chamber sidewall top arranges smoke inlet, the bottom is communicated with Waste gas outlet, and the flue gas that boundling fire tube backhaul chamber discharges enters the waste heat reservoir chamber by the smoke inlet of sidewall top, is discharged by the Waste gas outlet of bottom again.
Described air intake pre-heating energy-saving boiler is characterized in that: in the described waste heat reservoir chamber heat storage is housed, described heat storage is placed on the support network of savings indoor horizontal installation.
Described air intake pre-heating energy-saving boiler is characterized in that: hotair chamber one side of the adjacent wall of described waste heat reservoir chamber and hotair chamber is equipped with fin.
Described air intake pre-heating energy-saving boiler is characterized in that: described waste heat reservoir chamber top arranges regenerator and puts clearly mouth.
The beneficial effects of the utility model are: the fume afterheat that is arranged so that of waste heat reservoir chamber and hotair chamber occurs in boiler internal to the heating process of cold air, reduced the loss of heat, heat storage in the waste heat reservoir chamber can absorb the waste heat in the flue gas to a greater extent, to the heating of cold air high efficiency smooth more, can play simultaneously the effect that absorbs flue dust and pernicious gas, regenerator is put clearly mouth and is used for clearing up and change heat storage in the waste heat reservoir chamber, and the setting of fin can make the waste heat reservoir chamber that the efficiency of heating surface of hotair chamber is further improved.

Among the figure, 1-body of heater, 2-high-temperature flue gas mouth, 3-hotair chamber, the 4-hot air inlet, 5-stereo burning chamber, 6-waste heat reservoir chamber, the 7-Waste gas outlet, 8-heat collecting chamber, 9-boundling fire tube backhaul chamber, 10-re-firing chamber, the positive combustion chamber of 11-, 12-cool air inlet, the 13-smoke inlet, 14-support network, 15-water jacket, the 16-regenerator is put clearly mouth, 17-heat storage, 18-fin.
The specific embodiment
Such as Fig. 1 and 2, body of heater 1 is rectangular structure, and hotair chamber 3 is arranged on body of heater 1 positive centre position, and its outer side-lower is cool air inlet 12, and cold air enters hotair chamber 3 through entrance.There is outlet to be communicated with the hot air inlet 4 of re-firing chamber 10 at hotair chamber 3 inside fronts.Stereo burning chamber 5 is positioned at hotair chamber 3 rears, and it comprises the re-firing chamber 10 on top and the positive combustion chamber 11 of bottom.High-temperature flue gas mouth 2 also is set below stereo burning chamber 5, by high-temperature flue gas mouth 2 positive combustion chamber 11 is communicated with heat collecting chamber 8.Heat collecting chamber 8 is positioned at the position of furnace body inside below, 5 both sides, stereo burning chamber, be boundling fire tube backhaul chamber 9 above it, and heat collecting chamber 8 communicates with boundling fire tube backhaul chamber 9.The skin of body of heater 1 is water jacket 15.
Such as Fig. 3 to 5, hotair chamber 3 places in the waste heat reservoir chamber 6, the top of this waste heat reservoir chamber 6 connects the outlet of boundling fire tube backhaul chamber 9 by smoke inlet 13, the flue gas of discharging in the boundling fire tube backhaul chamber 9 is imported in the waste heat reservoir chamber 6, deposit heat storage 17 in the waste heat reservoir chamber 6 and absorb waste heat in the flue gas.Waste heat reservoir chamber 6 tops arrange regenerator and put clearly mouth 16, are used for placing or cleaning heat storage 17.The upper wall in hotair chamber one side of common sidewall at waste heat reservoir chamber 6 and hotair chamber 3 has fin 18.The bottom of waste heat reservoir chamber 6 is support network 14, connects the Waste gas outlet 7 of body of heater 1 bottom.
