112 full combustion of room, the heat of generation is passed in reservoir chamber 12 by the inner wall of burning gallery 111 carries out heating evaporation to water,
Meanwhile the flue gas for generation of burning passes through the first return duct 121 and the second return duct 122, can further utilize smoke pre-heating, together
When the first return duct 121 and the second return duct 122 between be provided with turbine boosted fan 2, and enhanced by turbine boosted fan 2
Pressure enables flue gas to be smoothly discharged, and the water in the reservoir chamber 12 for being also is accelerated by thermal evaporation.
The utility model has the technical effect that following aspect: passing through the burning for forming burning gallery and reversing chamber
Room, full combustion oil gas play the role of energy conservation and environmental protection and increase heat, and passes through the first return duct and the second return duct energy
Flue gas is enough conveyed, and makes the water boiling in water tank generate steam by the heat that flue gas conveys, steam is recycled to carry out
Power generation, and the first return duct and the second return duct are thermally conductive fast, can reduce heat and are expelled directly out with flue gas, are suitable for boiler hot
It recycles；In addition, the first return duct and the second return duct all with silica, kaolin, allophane powder, attapulgite powder,
Glass bead, bamboo charcoal powder, mineral wool, fibroin fiber, talcum powder, cellulose pulp and green body reinforcing agent calcium lignosulfonate
With sintering aid silicon nitride magnesium based on raw material, by mixing, rub and be prepared ceramic blank pipe, place by positive silicic acid
Immersion infiltration is carried out in hydrogel made from ethyl ester, calcium salt, magnesium salts and nitric acid, can close the gap in ceramic blank pipe, and
Hydrogel with the antioxygenic property that can be improved ceramic tube after ceramic form mixed sintering, further increase ceramic tube usability
Can, it is able to bear flue gas and corrosion, has the advantages that hardness is high, corrosion-resistant and long service life.
Certainly, the representative instance of above only the utility model, in addition to this, the utility model can also have other a variety of
Specific embodiment, all technical solutions formed using equivalent substitution or equivalent transformation all fall within the requires of the utility model protection
Within the scope of.
