In the invention, the structure of the furnace core with double layers is adopted; the ventilating pores, a secondary air course and the volatile substances of the fuels in the hearth are burnt in the upper part of the hearth for leading a secondary air inlet gap to gradually increase from the lower to the upper for supplying oxygen and leading the fuels to be more fully burnt, thus achieving the effect of non-smoke burning and improving the thermal efficiency.
Description
Technical field
The present invention relates to a kind of burner.
Background technology
It is combustion-supporting that the gasification burner of prior art mostly is air blast, adopts straight tube property individual layer flue, its combustion instability.Heat exchange is insufficient, and the thermal efficiency is not high.
Summary of the invention
The objective of the invention is to provide a kind of easy to operate, sufficient combustion, the novel high-efficiency and energy-saving air-returning gasification stove that heat exchange area is big.
The object of the present invention is achieved like this: a kind of high-efficient energy-conserving air-returning gasification stove, comprise body of heater, upper of furnace body is a furnace panel, and the bottom is a base, is provided with in the base except that ash bucket, feed inlet and smoke box lay respectively at the both sides of body of heater, all communicate with burner hearth, combustion chamber has inside and outside two-layer outward, is distributed with vent aperture on the internal layer combustion chamber, constitute the secondary oxygen system in the combustion chamber, the combustion chamber bottom is provided with grate and an air channel switch.Combustion chamber is divided into inside and outside two-layer, and the upper part of internal layer is connected with outer field upper part is airtight, has formed annular cavity between the inside and outside two-layer flue, communicates with base, constitutes the twice aeration air channel.Gone to the bottom by inversion bottleneck shape and constitute in the combustion chamber bottom, grate is arranged at bent neck.An air channel switch is turnover plate type structure or board plug type structure.The top of combustion chamber internal layer is the hourglass shape burner that contracts.The feed inlet cross section for be square, rectangle, circle or oval.Smoke box is two air duct type smoke boxes, establishes into mouth respectively in the smoke box upper and lower, constitutes upper flue and lower flue, also is provided with flue switch on the upper flue.
High-efficient energy-conserving air-returning gasification stove provided by the invention is compared based on the cooking stove that burns bavin with existing, and following improvement is arranged:
The one, combustion chamber is divided into inside and outside two-layer, the upper part of internal layer and outer field upper part by airtight be connected to make between the inside and outside two-layer flue formed annular cavity, communicate with base, be called the twice aeration air channel, the middle and upper part branch of its internal layer is distributed with numerous twice aerations space, volatile materials together with secondary air duct and burner hearth fuel makes the oxygen supply of increase gradually from bottom to top of secondary air space in the upper furnace burning, makes the more abundant burning of fuel, reaches the effect of smokeless combustion.Thermal efficiency height only needs 19 minutes with the boiled 4KG water of 1KG faggot, compares with traditional approach, and fuel saving is more than 50%.
The 2nd, gone to the bottom by inversion bottleneck shape and constitute in the combustion chamber bottom, grate is arranged at bent neck, prove through test of many times, its grate so as not to close being advisable of area of flue outlet, its shape of falling the bottleneck is gone to the bottom, have Venturi effect, the fixed carbon of especially suitable lower furnace portion fully burns, and combustion ashes is with gravity fall.
Three is that an air channel adjusting device is that an air channel switch is turnover plate type structure or board plug type structure, can doublely do the dedusting vent passages.
The 4th, the hourglass shape burner that contracts is made on the top of combustion chamber internal layer, is down funnel-form in the lower part, and numerous vent aperture are arranged above, simultaneously, adopts nonmetal resistant to elevated temperatures heat-storing material to make here.By the effect of Venturi effect, strengthened flue gas and Air mixing greatly, form very strong eddy current flame.
The 5th, on the body of heater one side feeding port road fire door is set.Control enters the air capacity in the stove, and its feed inlet can be made and be square, rectangle, circle etc., with oval best.
The 6th, described smoke box is two air channels, and gauge tap is set on upper flue, and when upper flue was closed, combustion-gas flow was forced to enter smoke box by lower flue, and flow process increases, flow velocity descends, and helps the deposition of heat exchange and flue dust.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples.
Fig. 1 is a sectional structure schematic diagram of the present invention.
Fig. 2 is the combustion chamber of the present invention top burner structural representation that contracts.
Fig. 3 is that combustion chamber of the present invention is gone to the bottom and is inverted bottleneck shape structural representation.
The specific embodiment
Structure of the present invention as shown in Figure 1, comprise body of heater 3, body of heater 3 tops are furnace panel 2, and the bottom is a base 7, are provided with in the base 7 except that ash bucket 8, feed inlet 6 and smoke box 11 lay respectively at the both sides of body of heater 3, all communicate, it is characterized in that with burner hearth: two-layer inside and outside having outside the combustion chamber 4, be distributed with vent aperture 1 on the internal layer combustion chamber, constitute the secondary oxygen system in the combustion chamber, combustion chamber 4 bottoms are placed with grate 15 and an air channel switch 9.Fuel joins the burner hearth from feed inlet 6, by an air channel switch 9 of combustion chamber 4 bottoms.Carry out air intake one time, carry out the secondary oxygen supply by secondary air passage 17 and vent aperture 1, the flue that combustion flue gas stream is made of body of heater and combustion chamber skin enters smoke box 11 and discharges.When lighting a fire, open the flue switch 18 of upper flue, upper flue 19 and lower flue 20 are kept clear, avoid the phenomenon of falling the cigarette that causes because of flue resistance.Treat to close flue switch 18 behind the hyperactivity of fire, upper flue 19 is closed, flue gas is discharged through lower flue 20, make full use of the heat of flue gas.
Fig. 2 is the burner structure that contracts on the combustion chamber after improving, and its inlet portion of falling the funnel-form 12 joins with combustion chamber internal layer 5 cylindrical shells.Its burner that contracts extends to aditus laryngis 13, and aditus laryngis 13 tops connect by hourglass shape burner 14, and its cylindrical links to each other with combustion chamber outer 4.Its integral body is the venturi tubulose, and intrinsic Venturi effect helps guiding the secondary wind of secondary intake opening, forms turbulent flame.
Fig. 3 goes to the bottom for a kind of improved combustion chamber, the main bottleneck shape structure of being inverted, and its curved surface tube reducing reducing 16 links to each other with combustion chamber internal layer 5, and its mouth cylindrical part is provided with 15. wind switches 9 of grate and is tubular, and links to each other with bottleneck.Fuel and lime-ash drop to ash bucket gradually with gravity.Its port bridge construction helps reducing combustion chamber to the bottom dispersed heat, helps improving furnace temperature.
