Abstract

The utility model discloses a flue heat exchanger of small boiler and pertains to heat exchange device of the boiler flue waste heat. The exchanger can fully absorb waste heat and improve heating efficiency of the boiler by increasing heat exchange area. The technology points essentially consist of that one section of the inner wall of the flue is provided with sheety hollow fire prevention plates and the area of each hollow fire prevention plate accounts for more than 1/2 of the flue section. The hollow of the fire prevention plates is communicated with the flue duct water jacket. The other section of the flue is provided with sheety salients and the area of each salient accounts for less than 1/2 of the flue area. The middle of each two salients is fixed with a hollow spoiler that is communicated with the flue duct water jacket by the pipe.

Description

A kind of chimney heat exchanger of miniature boiler
One, technical field
The utility model relates to the heat-exchange device of a kind of heat-exchange device of miniature boiler, particularly flue residue heat.
Two, background technology
General miniature boiler improves result of use in order to save the energy, except heating up water, cook as common cooking stove, has also increased water jacket at body of heater, flue, and the heat of water jacket interior heat water is heated by the heating installation bag that is installed in each room.The burner hearth of miniature boiler is very little, and the red-hot flue gas of fuel combustion enters flue soon.In order fully to absorb the waste heat of flue gas in the flue, except the flue outer wall is set up water jacket, the stove that has has also been set up the heat-absorbing water pipe of different shape in flue.In order to improve the thermal efficiency of miniature boiler, fuel saving reduces operating cost, also has great potentialities and can excavate aspect utilizing at flue residue heat.
Three, summary of the invention
The purpose of this utility model provides a kind of chimney heat exchanger of miniature boiler.It improves the circulating pathway of flue gas by increasing heat exchange area, and the heat of flue gas in the flue more is absorbed and used.Its technical scheme is: the hot-water coil pipe around flue is housed in the flue water jacket, and the intake-outlet of coil pipe is drawn separately.On one section inwall in flue hollow from level to level fire-proof plate is arranged, each hollow fire-proof plate occupies flue section 1/2nd above areas.Neighbouring two hollow fire-proof plates respectively from the walling of flue relative both sides stretch out, the hollow and flue water jacket of fire-proof plate communicates.The projection from level to level that distributes is up and down arranged on the inwall of another section of flue, and each projection occupies the flue section less than 1/2nd areas.Hollow choked flow cake is equipped with in every two-layer protruding centre position at the flue center, and the choked flow cake is communicated with the flue water jacket by pipeline.
The chimney heat exchanger of this miniature boiler has prolonged the flue gas circulating pathway, has increased the flue gas heat exchange area, and heat exchange efficiency improves, and has saved fuel, except cooking, heat the drink bath water of also can serving the meals, can also reduce the pollution of soot emissions.
Four, description of drawings
Described in detail below in conjunction with the utility model embodiment accompanying drawing:
Fig. 1 is the structural representation of the utility model miniature boiler chimney heat exchanger.
Five, the specific embodiment
As shown in Figure 1, the utility model chimney heat exchanger and boiler furnace join.Hot-water coil pipe 2 around flue is arranged in flue water jacket 1, and its intake-outlet 5 is drawn separately, joins to serving the meals with running water pipe and drinks the hot water that bathing is used.On one section inwall in flue, hollow from level to level fire-proof plate 6 is arranged, each fire-proof plate occupies the area of flue section more than 1/2nd, neighbouring two hollow fire-proof plates respectively from the walling of flue relatively both sides stretch out, the inner chamber of fire-proof plate communicates with flue water jacket 1.Another section in flue has up and down the projection 4 from level to level that distributes on the flue inwall, each projection occupies the flue section less than 1/2nd area.Projection is hollow, and its inner chamber communicates with the flue water jacket.The levels projection staggers mutually in the position of vertical direction.Spoiler 3 is equipped with in centre position in the every two-layer projection in flue center, and its stops flue gas flue of directly overflowing, and increase and walling of flue and protruding fully contacting are passed to water jacket with heat.Choked flow cake 3 is hollow, is communicated with water jacket 1 by pipeline.On the walling of flue between the two-layer projection, have ash removing opening, can clear up the choked flow cake and projection is amassed the cigarette ash that falls.Last cigarette ash is discharged from the flue bottom.

Claims (3)
