When grate area less than 0.035m
2The time, between vertical water jacket and the retort heat-insulation layer is housed.
On the madial wall that is positioned at the vertical water jacket part above the retort mouth, be provided with fin or heat exchanger tube.
Below vertical water jacket, be connected to and adopt the hot plate cover, at grate area less than 0.035m
2The time, adopt between hot plate cover and the retort heat-insulation layer is housed.
Between retort mouth and horizontal water jacket adjusting-flow board is housed, adjusting-flow board is by annular base, and half tube and loam cake are formed, and the half tube blocks the chimney porch, forms exhaust gases passes between half tube and the vertical water jacket.
Be provided with secondary wind inleting tube in the retort outside.
Be provided with the charge heating chamber below fire grate, it is made up of with the reverberation bowl that is positioned at furnace bottom the bottom of retort, and the relative fire door of reverberation bowl place has air inlet.
When burning was loose coal, horizontal water jacket was two-layer, and lower layer of water par cover is connected with vertical water jacket and forms burner hearth, is provided with the oblique triangle fin on the top of burner hearth, is provided with heat exchanger tube between the two-layer horizontal water jacket.Fire door place between two-layer horizontal water jacket is provided with adjusting-flow board, and adjusting-flow board is by annular base, and half tube and loam cake are formed, and the half tube blocks the chimney porch, forms exhaust gases passes between half tube and the vertical water jacket.
Below in conjunction with drawings and Examples the utility model is further described.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the vertical view of Fig. 1.
Fig. 3 is the structural representation of another embodiment of the present utility model.
Fig. 4 is the A-A profile of Fig. 3.
Fig. 5 is the B-B profile of Fig. 1.
Fig. 1,2 illustrated embodiments are to burn the heating stove of honeycomb briquette, and it is made up of body of heater 16, heat exchanging water-jacket and secondary heat exchange water.A heat exchanging water-jacket is the ladder water jacket, and the ladder water jacket is made up of with vertical water jacket 4 horizontal water jacket 7, and the two is connected.Horizontal water jacket 7 is positioned at retort mouth top, and vertical water jacket 4 is positioned at around the upper furnace.Return pipe 15 is equipped with in vertical water jacket bottom, and the grate area of present embodiment is less than 0.035m
2So, between vertical water jacket 4 and the retort 3 heat-insulation layer is housed.In order to strengthen heat exchange area, on the madial wall that is positioned at the vertical water jacket 4 above the retort mouth, be welded with fin 6.In order further to gather the heat that burner hearth sheds, below vertical water jacket 4, be connected to and adopt hot plate cover 17, adopting hot plate cover 17 can be the downward extension of vertical water jacket either side wallboard.Adopting hot plate cover 17 extends to below the retort middle part.Adopt between hot plate cover 17 and the retort heat-insulation layer is housed.
Secondary heat exchange water jacket 12 is the fume afterheat heat exchanging water-jacket, and it directly is connected with horizontal water jacket 7, and secondary heat exchange water jacket 12 peripheries are equipped with heat-insulation layer 11.The secondary heat exchange water jacket is again the part of smoke box, for increasing heat exchange area, be provided with fin or heat exchanger tube 13 in the certain altitude of high-temperature fuel gas porch, the current in the logical secondary heat exchange water jacket two side of heat exchanger tube 13 structures are discharged by the chimney 9 of secondary heat exchange water jacket top after the combustion gas heat exchange.Outlet pipe 10 is located at the top of secondary heat exchange water jacket 12.
Adjusting-flow board 5 is contained between retort mouth and the horizontal water jacket 7, and adjusting-flow board 5 is by annular base, and half tube and loam cake are formed.Half tube shelves are lived flue 14 porch, form exhaust gases passes between half tube and the vertical water jacket.Can further improve the thermal efficiency, take off adjusting-flow board when cooking.
Be provided with secondary wind inleting tube 19 in retort 3 outsides, secondary wind inleting tube 19 passes heat-insulation layer through to retort mouth place by furnace bottom, exceeds 10mm than retort mouth.At gas outlet, do not have the preceding aerating oxygen of secondary heat exchange like this, carbon monoxide is burnt away.Secondary air also can be made air intake passage in the retort wall, it is more even that many places air outlet ventilation is established in the inboard, plane on the furnace wall.
