Abstract
The interface exhaust smoke furnace is characterized in that the bottom of the hearth (7) is fixed on the fire grate (8).The discharge flue (1) is out of the furnace and the import is fixed in the furnace. A water jacket (3) is introduced between the external wall of the furnace and the discharge flue (1) and the hearth (7). The import of the smoke inducing tube (2) is fixed on the upper side of the fire grate (8) in the hearth (7) and the import of the smoke inducing tube (2) is introduced on the inner wall of the discharge flue (1) through the water jacket (3).
Description
One, technical field
The utility model relates to a kind of civilian normal-pressure hot-water boiler, especially interface smoke evacuation stove.
Two, background technology
At present, civilian normal-pressure boiler kind is more, is divided into vertically and horizontal from shape system, on the fuel combustion duty counter-burning type is arranged again, double-layer grate or the like technical scheme.These technology are most, discharge flue all is arranged on top, vertical heater combustion chamber or top, horizontal chamber furnace (oven) combustion chamber one sidewall, discover that a large amount of heats that exist the rising flue gas to carry are mainly used in heating upper strata fuel, and will fail the phenomenon that clean-burning fuel powder takes out of, so both waste fuel and heat energy, again air had been caused smoke contamination simultaneously.
Two, visitor in the invention
The purpose of this utility model is, proposes a kind of interface smoke evacuation stove, and promptly the flue gas that will carry calory burning from combustion boundary is drawn out to smokejack, promotes combustion position, can improve the boiler thermal energy conversion efficiency again.
The technical solution of the utility model is: the burner hearth bottom fixed grate, smokejack is opened on outside the body of heater, import is fixed in the body of heater, be fixed with water jacket between furnace outer wall and smokejack and burner hearth, draw the smoke pipe import and be fixed on burner hearth bottom fire grate upside, draw smoke pipe and open on the smokejack inwall through exporting behind the water jacket.
The utility model in use, during fuel combustion on the fire grate, form the abundant and higher combustion boundary of temperature of burning at the fire grate upside, the fire grate smoke pipe that draws nearby is transported to smokejack with the direct drainage of high-temperature flue gas that combustion boundary produces, so just form in the burner hearth from the top down flow air stream and fire grate downside air stream from bottom to top simultaneously on fire grate combustion boundary blow combustion-supporting duty, and after fully burning in the interface, flue gas clean and high temperature heats water jacket through drawing smoke pipe, not only can be fast and more efficient carry out thermal power transfer, the pollutants such as dust of Pai Chuing also obviously reduce simultaneously, burner hearth combustion heat-exchange high efficiency, save coal fuel, compliance with environmental protection requirements, the features simple structure practicality.
Three, description of drawings
Fig. 1 is the structural representation of the utility model embodiment 1
Fig. 2 be the utility model embodiment 1 draw the smoke pipe distribution schematic diagram
Fig. 3 is the structural representation of the utility model embodiment 2
Four, the specific embodiment
Embodiment 1: body of heater is a vertical heater, smokejack 1 is positioned at burner hearth 7 tops, burner hearth 7 bottom fixed grates 8, smokejack 1 is opened on outside the body of heater, smokejack 1 import is fixed in the body of heater, 7 in furnace outer wall and smokejack 1 and burner hearth are fixed with water jacket 3, draw smoke pipe 2 imports and are fixed on burner hearth 7 bottom fire grates 8 upsides, draw the 3 back outlets of smoke pipe 2 process water jackets and open on smokejack 1 inwall.
A plurality of smoke pipes 2 that draw that evenly distribute in the water jacket 3 draw smoke pipe 2 and are and stand vertically shape, or spiral-shaped.Water jacket 3 tops are delivery port 10 fixedly, and water jacket 3 bottoms are water inlet 11 fixedly.During by water jacket 3 band indoor heatings, circulating hot water flows to the heat radiation pipeline by water jacket 3 through delivery port 10, and backwater flows back to water jacket 3 through water inlet 11.
Burner hearth 7 middle parts have fuel and add mouth 5, and fire grate 8 upsides have except that cinder notch 6 in the burner hearth 7, and cleaning door 9 is arranged at fire grate 8 bottoms.
Evenly distribute in the burner hearth 7 and help hot-water line 4.Help hot-water line 4 to be opened in the water jacket 3, be and stand vertically shape, or spiral-shaped.Help hot-water line 4 through smokejack 1.Help between two openings of hot-water line 4 in water jacket 3 and keep difference in height.Help the effect of hot-water line 4 to be to increase the heat exchange area of water jacket 3.
During fuel combustion on the fire grate 8, form the abundant and higher combustion boundary of temperature of burning at fire grate 8 upsides, fire grate 8 smoke pipe 2 that draws nearby is transported to smokejack 1 with the direct drainage of high-temperature flue gas that combustion boundary produces, so just form in the burner hearth 7 from the top down flow air stream and fire grate 8 downsides air stream from bottom to top simultaneously on fire grate 8 combustion boundary blow combustion-supporting duty, and after fully burning in the interface, flue gas clean and high temperature heats through drawing 2 pairs of water jackets 3 of smoke pipe, not only can be fast and more efficient carry out thermal power transfer, the pollutants such as dust of Pai Chuing also obviously reduce simultaneously, burner hearth 7 combustion heat-exchange high efficiency, save coal fuel, compliance with environmental protection requirements, the features simple structure practicality.
Embodiment 2: body of heater is a horizontal chamber furnace (oven), burner hearth 7 bottom fixed grates 8, smokejack 1 is opened on outside the body of heater, smokejack 1 import is fixed on and is positioned at burner hearth 7 wall tops one side in the body of heater, 7 in furnace outer wall and smokejack 1 and burner hearth are fixed with water jacket 3, draw smoke pipe 2 imports and be fixed on burner hearth 7 bottom fire grates 8 upsides, draw the 3 back outlets of smoke pipe 2 process water jackets and open on smokejack 1 inwall.
Help hot-water line 4 to be opened in the water jacket 3.Help hot-water line 4 through burner hearth 7.Help hot-water line 4 through smokejack 1.Help between two openings of hot-water line 4 in water jacket 3 and keep difference in height.Help the effect of hot-water line 4 to be to increase the heat exchange area of water jacket 3.
