Abstract
There is a solid fuel combustion apparatus comprising a heated enclosure, a burner connected to the heated enclosure, and a means for providing a solid fuel from a solid fuel reservoir to the heated enclosure. The means for providing a solid fuel aspirates the solid fuel into the heated enclosure by creating a vacuum at a location in the heated enclosure. The vacuum establishes a pressure differential between the location in the heated enclosure and the solid fuel reservoir, which thereby aspirates the solid fuel from the reservoir to the heated enclosure where it is combusted by a flame from the burner.
Claims20
A solid fuel combustion apparatus comprising:
- a heated enclosure;
- means for providing an ignition flame in the heated enclosure;
- a first elongate tube having a first end and a second end opposite the first end, said second end of the first elongate tube extending into the heated enclosure;
- a second elongate tube, the first elongate tube being within and extending along the second elongate tube, the first and second elongate tubes providing a first channel therebetween;
- means for providing solid fuel being connected to the first channel at the first end of the first elongate tube and providing solid fuel thereto;
- a source of pressurized fluid being connected to the first elongate tube at the first end and providing the pressurized fluid to the heated enclosure, whereby the pressurized fluid is released into the heated enclosure thereby creating a pressure differential between the heated enclosure and the solid fuel feeder means along the first channel, said pressure differential aspirating the solid fuel into the heated enclosure where it is ignited by the ignition flame.
A method of supplying a heated enclosure with solid fuel comprising the steps of:
- supplying a stream of pressurized fluid into the interior of the heated enclosure, said stream providing a low pressure region at a location in the heated enclosure;
- connecting the low pressure region to a source of solid fuel, thereby creating a pressure gradient between the source of solid fuel and the low pressure region within the heated enclosure;
- and
- aspirating the solid fuel along the pressure gradient towards the inside of the heated enclosure, the solid fuel being aspirated due to the pressure gradient.
A solid fuel combustion apparatus comprising:
- a heated enclosure;
- a burner connected to the heated enclosure;
- means for providing a solid fuel to the burner;
- and
- means for preheating the solid fuel using thermal energy from the heated enclosure.
A method of supplying a heated enclosure with solid fuel comprising the steps of:
- aspirating the solid fuel from a reservoir through a conduit and into the heated enclosure;
- communicating heated fluid from the heated enclosure to the conduit;
- and
- preheating the solid fuel in the conduit with the heated fluid before the solid fuel enters the heated enclosure.
A solid fuel combustion apparatus comprising:
- a heated enclosure;
- a burner connected to the heated enclosure;
- and
- means for providing a solid fuel from a solid fuel reservoir to the heated enclosure, wherein the means for providing a solid fuel aspirates the solid fuel into the heated enclosure by creating a vacuum at a location in the heated enclosure, thereby establishing a pressure differential between the location in the heated enclosure and the solid fuel reservoir, thereby aspirating the solid fuel from the reservoir to the heated enclosure where it is combusted by a flame from the burner.
