Abstract

The utility model relates to a high efficient energy saving boiler drum, comprising a boiler drum wall 1, a boiler cavity 2, a flue 3, a boiler bridge 4, a dust hole 5 and a fire door 6, wherein, the upper part of the boiler cavity 2 forms a barrel shape, the lower part of the boiler cavity 2 forms a funnel shape, two end surfaces of the funnel are the local extension of the barrel, and two lateral surfaces are composed of sloping plates 10 welded on the two end surfaces; a fire door 6 is positioned on the end surface on one end; the boiler bridge 4 is composed of hollow tubes 9 which are communicated with a heating water box 7. The utility model has the advantages of long service life of the boiler bridge 4, reasonable structure of the boiler cavity 2, ignition with less fuel, high thermal efficiency, etc.

Description

The energy-saving efficient boiler flue

The utility model relates to a kind of boiler furnace flue that uses solid fuel, and is specially adapted to vertical middle and small burn coal boiler.

The lower furnace portion of existing boiler furnace flue is consistent with upper space mostly or only be slightly less than upper space, and its grate is that solid steel are made.Its defective is the yielding even burning ring of grate, and for medium small boiler, more imitation frosted glass greatly then need be piled up in the lower furnace portion space just can open fire.

The purpose of this utility model is that a kind of grate life-span of design is long, opens the easy and high energy-saving efficient boiler flue of the thermal efficiency of fire.

The utility model is achieved in that

A kind of energy-saving efficient boiler flue, relate to the courage wall, burner hearth is positioned at the flue of roof of the furnace, grate, ash-pit, vent, the base plate of flue bottom periphery and heating water tank is welded as a whole, and it is characterized in that upper furnace is a cylindrical shape, the bottom is the infundibulate that the cross section progressively dwindles, and grate is made of the many hollow tubes that are communicated with heating water tank.

Further scheme is, the both ends of the surface of lower furnace portion funnel shaped part be with top one to the part of cylinder, two sides are inclined-planes that swash plate constitutes.

Further scheme is, the inclined-plane is the arch inclined-plane, and hollow tube is welded between two swash plates, and vent is positioned at an end end face.

Further scheme is that the heat pipe that is communicated with heating water tank is housed below the flue in the burner hearth again.

The utility model has the advantages that the grate life-span is long, chamber design is more reasonable, can open fire with less fuel, and thermal efficiency height is best suited for the flue of making middle-size and small-size solid fuel fired boiler.

Below in conjunction with accompanying drawing the utility model is done detailed description.

As Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6 and Fig. 7, a kind of energy-saving efficient boiler flue, relate to courage wall 1, burner hearth 2, be positioned at the flue 3 of roof of the furnace, grate 4, ash-pit 5, vent 6, the base plate 8 of flue 1 bottom periphery and heating water tank is welded as a whole, and burner hearth 2 tops are cylindrical shapes, the bottom is the infundibulate that the cross section progressively dwindles, and the both ends of the surface of funnel shaped part are that extend the part of top cylinder, and two sides are to be welded in the arch inclined-plane that the swash plate 10 on the both ends of the surface constitutes, and vent is positioned on the end end face.Grate 4 is made of 4 pipes (9), and pipe 9 two ends are welded in respectively on two swash plates 10, and is communicated with heating water tank.

The heat pipe 11 that is communicated with heating water tank also is housed below the flue 3 in burner hearth 2.

As Fig. 8 and Fig. 9, this energy-saving efficient boiler flue is applied to the water example of dual-purpose stove of a kind of steamed rice, this boiler furnace flue is except that vent 6 and ash-pit 5, remainder all is wrapped in the heating water tank 7 (being the furnace wall), above heating water tank 7, be provided with steam box 13 that fuse with heating water tank 7 and that be communicated with steam channel 12, above steam box 13, be provided with water storage tank 14, flue 3 enters in the air after steam box 13 and water storage tank 14 middle passing, be communicated with by water pipe 15 and valve 16 between water storage tank 14 and the heating water tank 7, on water storage tank 14 and heating water tank 7, water level meter 17 is housed all, on heating water tank 7, also be equipped with and turn on the tap 18, thermometer, mudholes etc. for conveniently removing the incrustation scale in heat pipe 11 and the hollow tube 9, also are provided with manhole in the relevant position of heating water tank 7.
