Abstract

The utility model discloses a coal-saving flued stove of high water temperature, belonging to a small-sized domestic boiler. The technical key is that a fire wall is arranged on the connection of a fire box and a chimney flue, a hot water pipe is arranged inside the chimney flue, a water inlet of the water jacket are arranged on one stove leg connected with the water jacket, the water outlet is arranged on top of the water jacket of the chimney flue, three ash removal doors are arranged on the stove body and the chimney flue, a water heater bent pipe which is connected with water supply is arranged inside the water jacket of the chimney flue. The utility model is convenient in removing ash, rapid in heating, high in water temperature, which can save 40 percent of coal at the same condition of heat supply.

Description

High water temperature is economized the coal furnace

One, technical field: the utility model designs a kind of furnace, and furnace is used in particularly a kind of Home Heating, cooking more.

Two, background technology: existing domestic heating stove all is to set up water jacket on body of heater and flue, and what also have installs hot-water line additional in burner hearth and flue, and the shape and structure to fire box that also has is made different improvement.Yet the furnace coal consumption in existing the use is more.For example, the furnace that local Beijing of using, Shandong produce will consume coal 6-7 ton at 200 squares of floor spaces of heating period heating of five months, and heating temperature also is not too desirable.

Three, summary of the invention: the purpose of this utility model provides a kind of high water temperature and economizes the coal furnace, its heat energy utilization rate height, and heat supply water temperature height, coal consumption reduces greatly.Its technical scheme is: with flue (9) place of connection a wall with flues (2) of connecting with water jacket is arranged at burner hearth (1).The two heat extraction water pipes (8) that are communicated with the both sides water jacket are arranged in flue.The pipe bit interval of two heat extraction water pipes staggers, and the distance between two combs and walling of flue and two combs is no more than 2 centimetres.The flue water jacket extends on its stove leg in below, and water jacket water return outlet (12) is arranged on this stove leg.The opposite side relative with water inlet has ash door (11) on the body of heater below the flue.On a side walling of flue parallel with hot-water line hot-water line shoot door (3) is housed, the height of shoot door is identical with the height of hot-water line fitting limit in the flue.At flue water jacket top suit smoke canal elbow (4), there is flue shoot door (5) position that aligns at elbow end face and flue.The water heater bend pipe (13) that connects running water is housed in the flue water jacket.Hot water outlet (6) is contained in flue water jacket top.The structure of this furnace is heated soon hot-water line, and hot water circuit is fast, heat supply water temperature height.Water temperature is more than 80 degree during the stove fire normal combustion.Furnace body deashing is convenient, and service life is long.

Four, description of drawings: Fig. 1 is the structural representation that high water temperature is economized the coal furnace.

Fig. 2 is the partial schematic diagram of bath hot water device bend pipe.

Five, concrete true mode: be described further below in conjunction with accompanying drawing.There is water jacket to absorb heat in the stove in the burner hearth of furnace and flue outside.In furnace chamber, burner hearth 1 has a wall with flues 2 that is communicated with water jacket 10 with the junction of flue 9, and the pyrotechnics of burner hearth is risen enters flue after a wall with flues is raised, and makes the cooker heating above the body of heater fast.The two heat extraction water pipes that are communicated with the water jacket two side are arranged in the flue.The pipe bit interval of this two comb staggers, and the distance between two combs and flue and two combs is no more than 2 centimetres.Around flowing through, each hot-water line can both fully absorb flue gas heat between the hot-water line of flue gas in flue.The flue water jacket extends on its stove leg in below, on this stove leg the backwater mouth of pipe 12 is arranged, and effluent pipe mouth 6 is positioned at flue water jacket top.The intake-outlet discrepancy in elevation increases, and has accelerated the circulation of water in the system.On the body of heater below the flue, the opposite side that water inlet is relative has ash door 11, is used to remove cigarette ash in the stove.On a side walling of flue parallel with hot-water line hot-water line shoot door 3 is housed, the height of shoot door is identical with the height of hot-water line fitting limit in the flue.Be used for clearing up the long-pending cigarette ash that drops on the hot-water line, often deashing keeps the hot-water line cleaning, just makes hot-water line remain higher heat exchanger effectiveness.Suit smoke canal elbow 4 on the flue water jacket.Elbow inserted flue within the walls when stove was installed.There is flue shoot door 5 position that aligns at elbow end face and flue, is used to remove the dust stratification on the walling of flue.Can clean flues the easily dust stratification of each one of above-mentioned each deashing ash door makes the frequent efficiency operation of body of heater.In the flue water jacket of hot-water line shoot door 3 offsides, water heater bend pipe 13 is housed, joins by two interfaces 7 and running water.But its supplying clean hot water or bath water.

This furnace thermal efficiency height under stove fire normal combustion state, keeps more than 80 degree heat supply water temperature.It is remarkable to save coal simultaneously.Under identical heat supply situation, can economize coal more than 40%.
