The technical scheme that realizes above-mentioned purpose is as follows:
A kind of water vapour coal furnace, primary structure is a furnace, the heating installation body of heater is divided into inside and outside two-layer, in internal layer body of heater 5, set gradually water layer fire road traction plectane 7, fiery road towing plate 9 from top to bottom, be provided with many fire tubes 8 along separate routes on water layer fire road traction plectane 7, fire tube 8 is crooked downward vertically and be connected with fiery road towing plate 9 along separate routes, is provided with many heating calancrias 10 on fiery road towing plate 9, heating calancria 10 be bent downwardly and be divided into parallel two-layer, cross arrangement between the two-layer heating calancria.
Be provided with bottom cleaning door 8 in the furnace bottom, bottom cleaning door 8 positions are parallel with fiery road towing plate 9, are provided with top cleaning door 18 on furnace top, and the position of top cleaning door 18 is parallel with water layer fire road traction plectane 7.
When the utility model uses coal is added in the combustion furnace from charge door 21, the hot gas that burning produces is in quirk 20 enters internal layer body of heater 5, and from bottom to top respectively with heating calancria 10, fiery road towing plate 9, fire tube 8, water layer fire road traction plectane 7 fully contact along separate routes, in the water that transfer of heat is filled with in the above-mentioned parts, when the water in the stove reaches the temperature that needs, hot water is drawn use by the outlet pipe 19 that is located on the outer body of heater 13 of combustion furnace.Flue gas is discharged from the floss hole 2 that is located on the outer body of heater, also is provided with water supply mouth 3 on outer body of heater, by water supply mouth 3 cold water is added in the stove when the water in the stove is used to certain limit.
The utlity model has following beneficial effect:
1. simple in structure, primary structure of the present utility model is furnace and combustion furnace, is provided with heating pipe built-in in furnace, and is simple in structure, convenient production.
2. thermal efficiency height, energy savings is compared with traditional gas burner, and the heating calancria of setting up, water layer fire road traction plectane, fire tube, water layer fire road traction plectane have increased the area that contacts with hot-air greatly along separate routes, heat can be absorbed in a large number, thermal efficiency height.
