In FIG. 5, generally speaking, cartridge 18 includes adjustable valve 4, holder cartridge 5, valve fixer 6, cartridge cap 7 and pipe supporter 8. The adjustable valve 4 is inside holder cartridge 5, and fixed via valve fixer 6 and screws, the adjusting rod and knob of adjustable valve 4 are out of the holder cari:ridge 5. The pipe supporter 8 with flange is fixed on lower place on pipe 9, the lower end of pipe 9 sits on the gas outlet of adjustable valve 4. The cartridge cap 7 with thread holes around the center hole is mounted on the upper end of holder cartridge 5, the screws can fix cartridge cap 7 and pipe supporter 8 together. The adjustable valve 4 is referred to herein as means for the adjustment of propane gas flowing volume.
Generally furthermore speaking the manner of operation of cartridge 18, cartridge 18 transports propane gas from the inlet of adjustable valve 4 to the outlet of adjustable valve 4, and then to pipe 9, adjusting the knob of adjustable valve 4 to make the combusting flames big or small. The inlet of adjustable valve 4 connecting with hose 3, the outlet connecting with pipe 9, shown in FIG. 5.
Speaking only generally concerning the operating manner and purpose of the hose 3, when it is desired to activate propane, turning on propane valve 2, which is on propane tank 1, the propane gas flows into the hose 3, hose 3 links with propane valve 2 and adjustable valve 4, the flexible length of hose 3 depends on covering range need of burner head 19, hose 3 can be coiled and extended, and makes pipe 9 and burner head 19 in a portable and moveable operating manner to melt snow or ice in a desired area, also a certain extent of moving propane tank 1 helps hose 3 and burner head 19 cover more wide range, best view in FIG. 2.
Concerning the manner of operation of burner head 19, burner head 19 jets the flames downwardly. The propane gas comes from the pipe 9 and flows into the burner chamber i5.

Finally the mixed air and gas move out of the downward holes, which are made on the burner chamber 15. When it is desired to activate the burner head 19, press the igniter 13 button, the igniter 13 is energized, the instant spark comes out of the spark needle on the igniter 13, and ignites the air and gas mixture, the burner chamber 15 sprays a number of combusting flames downwardly for melting snow or ice directly, best view in FIG.4. The configuration and structure on igniter 13 will be described in more detail hereinafter.
Considering the purpose and manner of operation of the windproof elements 16, the windproof elements 16 include a plurality of superheated catalyzer element, which can relight mixed gas and air, and fixed on a frame, which incorporate the windproof elements 16. The windproof elements 16 are mounted on the lower end inside the enclosure 11, where is open downwardly, when the flames go through, the windproof elements 16 are red-hot. The main character of windproof element is when it is heated to red-hot by flames, even if the flames disappear, the windproof elements 16 can relight the mixed air and gas again quickly thereof, preventing flames from wind, best view in FIG.4 Igniter 13 comprises igniter button, piezo, wire and spark nozzle, which incorporate an igniter 13. Igniter button and piezo are mounted on the enclosure 11 shown in FIG.1 and FIG.2. The igniter wire is located inside the igniter wire pipe 12, the spark needle is mounted on the side of enclosure 11 and facing inside enclosure 11, the spark nozzle is perpendicular to the flowing direction of air and gas mixture, best: view in F1G.5.
In practice of the present invention, shown in FIGS, as mentioned above, the burner chamber 15 is positioned inside enclosure 11, a certain range of space between around burner chamber 15 edges and inside walls of enclosure 11 herein is required for a necessary air volume for combustion. It is apparent that needed air for combustion passes through the space clearances between around burner chamber 15 edges and inside walls of enclosure 11 to the inside enclosure 11, and then flows into the holes on pipe 9 described above, finally fixed with gas in the burner chamber 15. As propane combusting character that limits of inflammability, the percentage of gas in air mixture is at lower limit 2.4% and at upper limit 9.6%, thus a certain ratio range of area between gas gate area and total area of those holes on pipe 9 will be decided.
As mentioned above, the particularly advantageous embodiment of the invention illustrated, the jetting flames combust and melt snow or ice directly; flexible coiled and extended length of hose 3 makes the burner head 19 cover a desired range to melt snow or ice, also can move propane tank 1 on a cart to help burner head 19 and hose 9 cover more wide range; hose 3, pipe 9 and burner head 19 are portable and moveable to melt snow or ice;
windproof elements 16 prevent flames from wind; on the combination of hose 3, cartridge 18, pipe 9, rubber sleeve 10 and burner head 19 except propane tank 1 and propane valve 2, the inlet end of gas on the hose 3 can also put on the propane tank of a gas grill to take the heating source, no need for another propane tank when a gas grill exists;
the combination of burner head 19 with a partial pipe and a gas grill can be a complete grill for barbeque, when the snow burner is needed in winter, take out burner head 19 and adjustable valve 4 from the grill, assemble with other parts mentioned above as a complete combusting snow burner.
Considering the liquid propane combusting performance, liquid propane heating values after vaporization is 21548 Btu/pound, for a popular 20 Ib liquid propane tank, it has a total of heating values 430980 But. For melting and opening the accumulated snow on a driveway, which snow is height 0.3 m, length 12 m, width 2 m, snow temperature minus 5 Celsius degree, the needed heating capacity is 21394.8 Btu. Therefore theoretically calculation, a full of 20 Ib liquid propane tank energy can melt that driveway snow 20.14 times. It becomes readily apparent that the present invention is practical.
Having illustrated and described the principles of the present invention in a preferred embodiment thereof, it should be readily apparent that various changes and modifications can be made without departing from the scope of the invention as defined in the claims. I
claim all modifications coming within the scope of the accompanying claims.

When it is desired to activate the burner head 19, press the igniter 13 button, the igniter 13 is energized, the instant spark comes out of the spark needle on the igniter 13, and ignites the air and gas mixture, the burner chamber 15 sprays a number of combusting flames downwardly for melting snow or ice directly, best view in FIG.4. The configuration and structure on igniter 13 will be described in more detail hereinafter.
Considering the purpose and manner of operation of the windproof elements 16, the windproof elements 16 include a plurality of superheated catalyzer element, which can relight mixed gas and air, and fixed on a frame, which incorporate the windproof elements 16. The windproof elements 16 are mounted on the lower end inside the enclosure 11, where is open downwardly, when the flames go through, the windproof elements 16 are red-hot. The main character of windproof element is when it is heated to red-hot by flames, even if the flames disappear, the windproof elements 16 can relight the mixed air and gas again quickly thereof, preventing flames from wind, best view in FIG.4 Igniter 13 comprises igniter button, piezo, wire and spark nozzle, which incorporate an igniter 13. Igniter button and piezo are mounted on the enclosure 11 shown in FIG.1 and FIG.2. The igniter wire is located inside the igniter wire pipe 12, the spark needle is mounted on the side of enclosure 11 and facing inside enclosure 11, the spark nozzle is perpendicular to the flowing direction of air and gas mixture, best: view in F1G.5.
In practice of the present invention, shown in FIGS, as mentioned above, the burner chamber 15 is positioned inside enclosure 11, a certain range of space between around burner chamber 15 edges and inside walls of enclosure 11 herein is required for a necessary air volume for combustion. It is apparent that needed air for combustion passes through the space clearances between around burner chamber 15 edges and inside walls of enclosure 11 to the inside enclosure 11, and then flows into the holes on pipe 9 described above, finally fixed with gas in the burner chamber 15. As propane combusting character that limits of inflammability, the percentage of gas in air mixture is at lower limit 2.4% and at upper limit 9.6%, thus a certain ratio range of area between gas gate area and total area of those holes on pipe 9 will be decided.
As mentioned above, the particularly advantageous embodiment of the invention illustrated, the jetting flames combust and melt snow or ice directly; flexible coiled and extended length of hose 3 makes the burner head 19 cover a desired range to melt snow or ice, also can move propane tank 1 on a cart to help burner head 19 and hose 9 cover more wide range; hose 3, pipe 9 and burner head 19 are portable and moveable to melt snow or ice;
windproof elements 16 prevent flames from wind; on the combination of hose 3, cartridge 18, pipe 9, rubber sleeve 10 and burner head 19 except propane tank 1 and propane valve 2, the inlet end of gas on the hose 3 can also put on the propane tank of a gas grill to take the heating source, no need for another propane tank when a gas grill exists;
the combination of burner head 19 with a partial pipe and a gas grill can be a complete grill for barbeque, when the snow burner is needed in winter, take out burner head 19 and adjustable valve 4 from the grill, assemble with other parts mentioned above as a complete combusting snow burner.
Considering the liquid propane combusting performance, liquid propane heating values after vaporization is 21548 Btu/pound, for a popular 20 Ib liquid propane tank, it has a total of heating values 430980 But. For melting and opening the accumulated snow on a driveway, which snow is height 0.3 m, length 12 m, width 2 m, snow temperature minus 5 Celsius degree, the needed heating capacity is 21394.8 Btu. Therefore theoretically calculation, a full of 20 Ib liquid propane tank energy can melt that driveway snow 20.14 times. It becomes readily apparent that the present invention is practical.
Having illustrated and described the principles of the present invention in a preferred embodiment thereof, it should be readily apparent that various changes and modifications can be made without departing from the scope of the invention as defined in the claims. I
claim all modifications coming within the scope of the accompanying claims.
