Abstract
The utility model relates to a heat exchanger for coal stoves, which is suitable for stoves such as small-size heating stoves, water stoves, etc. The existing heating stove generally has the problems of low heat efficiency and difficult cooking. The heat exchange surface is increased by improving heat absorption sheets and increasing radiating fins in the heat exchanger, wherein the heat radiation area is increased in multiples; the heat exchange capability is greatly improved; water circulation can be promoted; the heat efficiency is obviously increased; the needs of heating and cooking can be well satisfied.
Description
The utility model is a kind of coal furnace heat exchanger, can be used for heating stove drinking water boiler etc.
The present heating stove that uses, its heat exchanger as shown in Figure 1, the heat that coal combustion produces passes to inwall (1) by the boiler clothing of being made by mud (or seat clay) and passes in the recirculated water by the inwall steel plate.Its heat exchange area is the surface area of drum inwall, heat exchange area, and particularly area of dissipation is very little, and a large amount of heats run off with flue gas.Though the heating stove that has has increased heat absorbing sheet (3) at the fire door place, since the suitable flow of flue gas direction arrangement of heat absorbing sheet, flue gas parallel baffled heat absorbing sheet, the heat exchange weak effect, heating installation heats up slow, and the thermal efficiency is low, the coal-fired waste seriously.And the distance of coal-fired and fire door is bigger, greatly reduces the firepower of fire door, the cooking difficulty.
The purpose of this utility model provides a kind of new type heat exchanger.It can improve the thermal efficiency of heating stove significantly, guarantees heating.And can provide enough firepower to be used for cooking.
The structure of this new type heat exchanger as shown in Figure 2.Its heat absorbing side is advisable the quantity that present vertical heat absorbing sheet is modified into horizontal heat absorbing sheet (3) heat absorbing sheet vertical with flue gas flow direction with the 3-4 layer.Be unfavorable for heat absorption very little, then too big too much to flue gas resistance, unfavorable to burning of coal.Every layer of uniform an amount of pore of heat absorbing sheet (10), the pore of adjacent layer will stagger (as Fig. 4), make the directly vertical heating heat absorbing sheet of flue gas by pore, and therefore, heat absorbing sheet can absorb heat to greatest extent.The ring cover (9) that can rotate adjusting is arranged on the heat absorbing sheet, have on the ring cover with heat absorbing sheet on identical pore (as Fig. 3).There is collection fire tube (4) the heat absorbing sheet inboard, on the collection fire tube collection fire-cylinder cover (5) is arranged.Heat radiation side at heat exchanger has increased the vertically fin (8) of (or helical form) layout.Fin can be made " I " shape, " V ", " U " shape or other shape.
The utility model heat exchanger is compared with existing product, and the horizontal heat absorbing sheet vertical with flue gas flow direction adopted in heat absorption, and endotherm area is big, and heat absorbing sheet can absorb the heat in the flue gas to greatest extent, and endothermic effect significantly improves.Heat radiation side has increased fin, and area of dissipation is multiplied than existing product, and can promote the circulation of water, so the thermal efficiency improves a lot.Laterally distance coal-fired and fire door has been dwindled in the employing of heat absorbing sheet, guarantees that cooking has enough firepower, so this heat exchanger not only can satisfy the needs of heating and cooking well, and thermal efficiency height, save coal-fired.
Description of drawings: 1, inwall 2, outer wall 3, heat absorbing sheet 4, collection fire tube 5, collection fire-cylinder cover 6, recirculated water go out 7, recirculated water inlet 8, fin 9, ring cover 10, pore.
The utility model heat exchanger manufacturing process technology relatively tube is single, can use steel plate, and steel pipe processing is welded, and also can adopt the cast-in-block method to make.Using method: cover the collection fire-cylinder cover during heating, the swivel becket female cap, making pore on the ring cover overlap flue gas with pore on the heat absorbing sheet flows out through heat absorbing sheet, recirculated water obtains maximum heat, during cooking, opens the collection fire-cylinder cover, the swivel becket female cap, sealing heat absorbing sheet pore, flue gas are all flowed out by collection fire tube, guarantee that cooking has enough firepower.
Claims (1)
1, a kind of coal furnace heat exchanger is characterized in that heat absorbing side adopts and the heat absorbing sheet of flue gas stream to vertical lateral arrangement, and heat radiation side has increased the fin that can be made into different shape.
