The specific embodiment
A kind of burning of heating system and heat-exchange system comprise the combustion system of bottom and the heat-exchange system on top, and described combustion system comprises the combustion boat 2 in the combustion chamber 1; Described heat-exchange system is the composite construction of plate-type heat-exchange pipe 4 and pipe type heat transfer pipe 10 and splitter 5 compositions.
The structure of described plate-type heat-exchange pipe 4 is: the plate-type heat-exchange pipe 4 of some internal run-throughs, plate-type heat-exchange pipe 4 is positioned on the splitter 5, be distributed with some through holes on the splitter 5, the pipe of plate-type heat-exchange pipe 4 internal run-throughs is horizontally set, be provided with the slit between the plate-type heat-exchange pipe 4, each slit is corresponding with each through hole of splitter 5, and the flue gas in the combustion chamber 1 flows from bottom to top from the slit between the board-like heat exchanger tube 4, and plate-type heat-exchange pipe 4 internal run-through pipes communicate with the hot air discharge mouth of heating system; Described pipe type heat transfer tubular construction is: the upper end, slit between the plate-type heat-exchange pipe 4 communicates with the upper end of pipe type heat transfer pipe 10, pipe type heat transfer pipe 10 is straight-through shape structure, the lower end of pipe type heat transfer pipe 10 communicates with exhaust opening, the peripheral outlet end of pipe type heat transfer pipe 10 communicates with the hot air discharge mouth of heating system, and entrance point communicates with air inlet by cross flow fan.
Combustion boat 2 integral body are a cell body, and the bottom surface of cell body is provided with some bottom surfaces air vent; The waist of cell body is provided with an air inlet; The top of cell body is provided with some air vents of going up, and air vent, air inlet and last air vent all communicate with blast pipe 8.Described plate-type heat-exchange pipe 4 is preferably ten.Pipe type heat transfer pipe 10 is preferably four.
By 6 chargings of tilting feed pipe, fuel in the combustion boat 2 is by behind fire rod 21 ignition combustions, hot gas and flue gas are together by at first disperseing flue gas and hot gas by the through hole on the splitter 5 by splitter 5, hot gas and flue gas are by the slit between the plate-type heat-exchange pipe 4 then, by slit flue gas and the hot gas between the plate-type heat-exchange pipe 4, the part heat is transmitted in the pipe of plate-type heat-exchange pipe 4 internal run-throughs by plate-type heat-exchange pipe 4 heat, and heat is discharged by the heat floss hole of heating system again.
Hot gas by the slit between the plate-type heat-exchange pipe 4 and flue gas are again by pipe type heat transfer pipe 10, the heat that pipe type heat transfer pipe 10 absorbs is transmitted to outside the pipe type heat transfer pipe by tube wall, the outer hot gas of pipe type heat transfer pipe imports the hot gas of discharging in the plate-type heat-exchange pipe 4, be discharged to the heat floss hole then together, after cross flow fan is opened, improved the flow velocity that hot gas is discharged.
So at first be plate-type heat-exchange, and then be pipe type heat transfer, two kinds of complex method heat absorptions.
Plate-type heat-exchange pipe 4 inner chambers are by the heat of the flue gas of outside conduction heating, and the hot gas in the plate-type heat-exchange pipe comes out by thermovent.Flow through the pipe type heat transfer pipe again through the flue gas behind the plate-type heat-exchange pipe seam crack, the outer reverse Quilt with air conditioning heating of pipe type heat transfer pipe, distribute by thermovent the heating back, and secondary absorbs heat like this, reduces thermal loss.There is not the flue gas of heat to discharge outdoor by discharge flue.The pipe heat exchanger at body of heater middle part, the mode that adopts flue gas in heat exchanger tube, to flow, 1, makes things convenient for deashing, 2, the moving air drag minimum of cold air plate-pipe clamp laminar flow, 3, cold air can cool off and reclaim the heat in the red-hot combustion chamber, increased the recuperation of heat ability, prolonged the life-span of furnace internal-lining, 4, make the convection flow fan installation site be in more rational state.
For guaranteeing abundant burning, adopt three times the air feed structure.The combustion boat bottom is a wind, and air quantity is the 60-80% of total blast volume; The combustion boat waist is established secondary wind, and air quantity is the 20-30% of total blast volume; Introduce a small amount of tertiary air from feeder sleeve, account for the 10-15% of total blast volume.
The air inlet of combustion boat 2 oral areas and granular fuel charging aperture share, and the granular fuel charging aperture is skewed, and discharge end is lower than feed end; Feed end is provided with dispenser, and dispenser and split-pole gear motor are in transmission connection.In feed, there is a spot of oxygen to bring into.
The bottom of combustion boat is provided with grey box, and dispenser adds granular fuel by material inlet, and dispenser is positioned at feed pipe.
Cross flow fan is electrically connected with blast switch, opens blast switch 31 and just can start cross flow fan.The plate-type heat exchange structure of burner part, 1, can be under the situation that does not increase the body of heater width, increase heat exchange area to greatest extent, prolong smoke heat exchange distance, 2, reduce fume side and air side flow resistance significantly, reduce power of fan, 3, this structure has also taken into full account the convenience of cigarette ash cleaning, open the top cover plate, can completely coming out in whole heat exchanger inside, makes deashing more thorough, and 4, be installed in plate type heat exchanger smoke inlet flue gas shunting plate, the flue gas that enters heat exchanger is evenly distributed, to give full play to the heat exchange performance of heat exchanger.
