Abstract
The utility model provides a liner of a coal stove for burning bulk coal, which is characterized in that "
The stainless steel inner cylinder has outer cylinder, several upper air inlet holes and lower air inlet holes in the upper and lower cylinder walls, and the inner cylinder above the upper air inlet holes is connected to the air collecting hood connected to the outer cylinder.
Description
The utility model relates to coal furnace, more particularly relates to the flue that the burning Loose-coal stove uses.
The bulk coal-fired flue of combustion of existing public use is for to fire cylindrical shape or the taper flue that forms with refractory material, and during use, flue places the fire grate top, and fire coal is deposited in the flue above the fire grate and burns.Its weak point is because the smoke chamber anoxic causes incomplete combustion and over-emitting black exhaust, not only caused energy waste but also caused air pollution, in addition, owing to making unburnt fritter black coal or black coal particle, anoxic falls again by the coal seam, caused the waste of coal, initially lighted besides or get angry when needing the coal seam normal combustion slow.
The purpose of this utility model provides a kind of coal combustion novel double-layer flue of over-emitting black exhaust not fully that helps.
The purpose of this utility model can realize by following measure:
This flue adopts thin corrosion resistant plate to make, and is made of inner core and urceolus, be "
" the stainless steel inner core of shape has urceolus outward, is respectively equipped with air admission hole on several, air admission hole down on the barrel of inner core upper and lower part, the inner core of last air admission hole top is connected with the gas skirt that is connected with urceolus, urceolus bottom, gas skirt and inner core formation air heat road.
The purpose of this utility model also can realize by following measure:
There is the connecting plate muscle that is connected in inner core top and urceolus top the top of gas skirt.
The utility model once uses the back to place a period of time owing to adopt corrosion resistant plate to make, and does not influence and uses next time, and the life-span is long.As adopt carbon steel, and connect coming off of one deck just begin one deck after once using, can all become fragment in very short time.When using the utility model, because this flue is placed the fire grate top, the part air enters the air heat road of urceolus and inner core formation through fire grate, hot-air after heating enters smoke chamber by last air admission hole, make because anoxic and not burned flue gas is fully burned, both avoid over-emitting black exhaust, increased calorific value again; Simultaneously,, make because anoxic and burning away to after-flame, thereby avoided the waste of coal without clean-burning small coal or coal particle because the portion of hot air enters burning zone by following air admission hole.In addition,, both helped flue gas and fully burnt fully, the initial programming rate of burning zone is accelerated owing to this flue being designed to similar " drum " shape and the urceolus that is placed in its outside is set outer tube is heated air.
Fig. 1 is the structural representation of embodiment of the present utility model;
Be "
" be with urceolus 1 outside the outside of inner core 2 of shape; on the inner core 2; bottom is respectively equipped with air admission hole 7; following air admission hole 8; gas skirt 4 that the outer shroud Zhou Lianyou of the inner core 2 above last air admission hole 7 is connected with urceolus 1; inner core 2, the space that constitutes between gas skirt 4 and urceolus 1 bottom is air heat road 3, air enters air heat road 3 by the fire grate of bottom, behind inner core 2 indirect heat exchanges, pass through last air admission hole 7 respectively, following air admission hole 8 enters smoke chamber, burning zone, for making inner core 2 more firm with urceolus 1 relative connection, outside inner core 1 is suitable for reading, be connected with connecting plate muscle 6 in suitable for reading to urceolus 1, said connecting plate muscle 6 can be a plate, also can be bar at interval, at connecting plate muscle 6 and urceolus 1, the space fill insulant material 5 that gas skirt 4 constitutes.
Claims (2)
1, a kind of novel double-layer flue, it is characterized in that being "
" the stainless steel inner core (2) of shape is outer that urceolus (1) arranged; be respectively equipped with air admission hole several on (7), air admission hole (8) down on the barrel of inner core (2) upper and lower part; the inner core (2) of going up air admission hole 7 tops is connected with the gas skirt (4) that is connected with urceolus (1), urceolus (1) bottom, gas skirt (4) and inner core (2) formation air heat road (3).
2, a kind of novel double-layer flue according to claim 1, it is characterized in that being positioned at gas skirt (4) top has the connecting plate muscle (6) that is connected in inner core (2) top and urceolus (1) top.
