The specific embodiment
A kind of non-pressure hot water generator, its structure as shown in Figure 1, 2.The combustion chamber 8 that cover is formed in comprising, the outer shape of combustion chamber 8 and the similar water receptacle of common combustion chamber shape, combustion chamber 8 walls are the hollow-core construction that sheet metal is made, dress water in it.The top of combustion chamber 8 is to have circular combustion chamber top, and middle part, combustion chamber top has circular hole, is fire door 3.The intermediate space of combustion chamber 8 is a burner hearth 16, and flue 2 is arranged in the burner hearth 16.Flue 2 is small-sized heaters, and the bottom of flue 2 is connected by the lower space of water inlet pipe 9 with combustion chamber 8.The top of the bottom of combustion chamber 8 and stove 10 bridges is suitable, and is distributed with the interface with grate 10 intracavity inter-connections.Flue 10 is arranged at burner hearth 16 tops, and the bottom of flue 10 has blowoff valve 12.The below of grate 10 is and grate 10 bottom shape adapting that the top of grate 10 is furnished with the interface with combustion chamber 8 intracavity inter-connections.The below of grate 10 is the air channel, and described air channel is the inlet and the passage of coal burning required air in the burner hearth 16, also is the passing away of last ashes after the fuel combustion.Drawer 13 is installed on the air channel, and drawer 13 can carry coal ash, by regulating the position of drawer 13, can control the size of air door air intake vent.The outside of combustion chamber 8 is an overcoat 6, the hollow-core construction that overcoat wall is also made for sheet metal.Space between overcoat 6 and the combustion chamber 8 is the passage that burner hearth 16 leads to chimney, and flue outlet 15 and the sparge pipe 14 that is connected with chimney arranged at the bottom of this passage, and the water of sparge pipe 14 ejections can absorb dust granules in the flue gas.The bottom of overcoat 6 is connected with water inlet pipe 11.Fire door 3 is placed with pot frame 4.
Water is come in from the water inlet pipe 15 of jacket bottom, and the water in the overcoat 6 accept that the heat of hot gas constantly heats up in the sandwich passage, and the water that temperature is high rises gradually.The higher water of overcoat 6 head temperature causes hollow grate 10 through tube connector 7, and the water in the grate 10 raises through heating-up temperature, cover 8 in constantly rising to.The top of cover 8 in the water part of interior cover 8 directly rises to, a part is in tube connector 9 causes the flue 2 at burner hearth 16 middle parts in addition.Water part in the flue 2 enters the annular heated body 5 that is positioned at burner hearth 16 tops from the bottom through tube connector 17, and another part enters annular heated body 5 from the top through tube connector 17.The top of cover 8 in the water of annular heated body 5 enters after heating, the hot water at cover 8 tops causes outside the stove through hot water outlet pipe 1 in arriving.The effect of parts such as the flue 2 in the burner hearth 16, tube connector 17 has two: the one, and the water in the heating flue 2, the one, the space in the separated furnace 16 helps to the ventilation of the fuel in the burner hearth 16, for fuel provides sufficient oxygen.Fuel ashes in the burner hearth 16 fall into 13 li in drawer in the air channel.
