The specific embodiment
Below in conjunction with drawings and Examples the utility model is described in further details.
Embodiment 1, it comprises flue 1, furnace shell 3, shell 4, smoke pipe 14, heat-exchange tube 5, the turnover joint 6 of heat-exchange tube and combustor interface 11, filling with insulation material between furnace shell 3 and shell 4, be provided with the smoke pipe 14 more than 3 on flue 1 top, the lower end of smoke pipe 14 communicates with flue 1, the upper end of smoke pipe 14 communicates with the fume collecting chamber 15 on furnace shell 3 tops, fume collecting chamber 15 tops are provided with smokejack interface 16, flue 17 runs on the smokejack interface 16, be filled with water between furnace shell 3 and flue 1 and form water jacket, water jacket outer wall direct and smoke pipe 14 carries out heat exchange, thereby make the water storage in the furnace shell 3 be produced higher temperature, generally speaking, hot water temperature in the water jacket is designed to about 85 ℃, is respectively arranged with outlet conduit joint 8 and backwater interface 12 on shell 4, the inner of outlet conduit joint 8 and backwater interface 12 communicates with furnace shell 3 inner chambers respectively, the outer end of outlet conduit joint 8 and backwater interface 12 joins with heating systems such as blower fan radiators respectively, and it mainly is to be used for heating; In order to realize the function of hot-water supply simultaneously, by increasing by one group of copper tube coil in the water jacket between furnace shell and flue again, the i.e. heat exchanger coil 5 that joins with the hot-water supply system, because of the hot water temperature in the water jacket generally is designed to about 85 ℃, hot water in heat exchanger coil 5 and the water jacket carries out heat exchange, generally speaking, circulating water temperature in the heat exchanger coil 5 is reached about 45 ℃, the two ends of heat exchanger coil 5 respectively with shell 4 on the domestic water turnover joint 6 that is provided with join, for the user provides life hot water.Be integrated in the furnace shell 3 by heat exchanger coil, thereby can be embodied as the heat energy that the user both provided heating usefulness, life hot water also can be provided two cover autonomous systems.Match with burner and be connected in the outer end of flue 1, this burner can be selected German prestige rope or the high board burner of Italy's meaning for use, by being connected with control circuit such as controller 10, also can temp probe be set, thereby make all temperature, combustion system, heating etc. all can realize Automatic Control by temp probe interface 9.Consult Fig. 1 to Fig. 3.
For avoiding build-up of limescale, the top of flue 1 can be made into the ramped shaped structure, promptly the flue top is inclined design, impurity such as the incrustation scale that sinks, because of the gravity effect, meeting is landing downwards naturally along the inclined-plane, and reduces the incrusted deposit on flue top.
In order to prevent thermal losses and to prevent that skin temperature is too high, insulating pad layer 13 can be set in the bottom of flue 1, thereby play the effect of heat-insulation and heat-preservation.Simultaneously, also can be provided with shell heat radiation window 7 by shell 4
Regularly clean for convenience, be provided with the sewage discharge joint 19 that is used for blowdown in the body of heater bottom.
Embodiment 2, in order further to improve the thermal efficiency, the utility model has carried out significant improvement to smoke pipe, i.e. suit flue gas baffling sheet 2 in smoke pipe 14, described flue gas baffling sheet 2 comprises baffling lamellar body 22, through hole 23 and tabs 24, is cut with the through hole 23 more than 2 or 2 on straight tabular baffling lamellar body 22, is theoretically, The more the better, the relative baffling lamellar body 22 both sides tabs 24 that barrier effect has been arranged arranged in a crossed manner respectively on the top of each through hole 23.Consult Fig. 4 to Fig. 8.
For convenient processing is handled, we are when processing through hole 23, and does not cut on through hole 23 tops, even cutting part still connects into an integral body with lamellar body, the cutting of through hole 23 is partly stretched out respectively to the left and right, formed the tabs 24 of barrier effect on through hole 23 tops.For easy to process and play barrier effect better, described tabs 24 preferably is made into semicircle shape, theoretically, the radius of tabs 24 equal baffling lamellar body 22 width 1/2nd for best, thereby play barrier effect better; But be easy to process, make the radius of tabs 24 be slightly less than 1/2nd of baffling lamellar body 22 width and get final product.Angle between tabs 24 and the baffling lamellar body 22 is equal to or less than 90 degree.Described flue gas baffling sheet can adopt the sheet material of 0.5 millimeters thick, and material preferably adopts 1Cr18Ni9Ti, and it can bear 900 ℃ flue-gas temperature.For easy to process, the width of baffling lamellar body 22 is little 2 millimeters than the smoke pipe internal diameter, goes out a plurality of semicircle camber lines through punch press, and a first from left parts not outside knuckle on the right side and formed tabs 24 for 90 ° then.
Flue gas baffling sheet is sleeved in the smoke pipe 14, baffling lamellar body 22 be slightly less than or width equals the internal diameter of smoke pipe 14.Make to form between smoke pipe 14 inwalls and the baffling lamellar body 22 to closely cooperate as far as possible, thereby make it to install and use conveniently, can play the choked flow effect better again.Also can pass through to place flue gas baffling sheet in the smoke pipe of traditional vertical fire tube fuel oil, gas fired-boiler, make flue gas be forced to turn back in smoke pipe and upwards move, flue gas prolongs running time in smoke pipe, with the heat exchange enhancing of smoke pipe wall.It mainly is to be applied on fuel oil, combustion gas fire tube hot-water boiler and the domestic small hot-water boiler.Consult Fig. 4 to Fig. 5.
Be that example further specifies now for gas-firing, natural gas burns in flue 1, gas fume after burning directly upwards flows from smoke pipe 14, because of placing flue gas baffling sheet 2 in the smoke pipe 14, make flue gas in smoke pipe, be forced to the operation of turning back, significantly improve the flue gas heat exchange coefficient, through overtesting and calculating: the coefficient of heat transfer of flue gas and smoke pipe wall is up to 98Kcal/m
2℃, be the coefficient of heat transfer (19Kcal/m of original smoke pipe
2℃) 5 times, be the coefficient of heat transfer (27Kcal/m of threaded flue
2℃) 3.5 times.Because the huge raising of the coefficient of heat transfer can reduce 70% with the stream heating surface area, makes this traditional type of furnace reduce 40% on volume and weight, cost significantly reduces.The raising of the coefficient of heat transfer makes exhaust gas temperature reduce to about 110 ℃, and boiler overall thermal efficient can be up to 90%, thereby it is more remarkable to make it energy-saving effect.Owing to set up the flue gas spoiler, make boiler efficiency increase substantially, the boiler structure compactness, volume significantly dwindles.
