Oil heater

Oil heater for burning of petroleum fuel comprising:

• a. combustion chamber means including a lower portion front access, a top portion access, and an upper portion rear vent;
• b. air introducing means including a closed annular channel having a plurality of spaced holes in the inner and outer surfaces of the closed channel whereby combustion air flows in all directions, located in a mid portion of said chamber means and connected to an air blower;
• c. fuel droplet tube introducing means supported in an upper portion of said chamber means and connected to a source of fuel through a pump whereby fuel droplets fall from the tube through the closed annular channel where combustion of a portion of the droplets occurs, those droplets not burning at that point continuing their fall through the channel to a vaporizer pan means;
• and
• d. vaporizer pan means located in a lower portion of said chamber means whereby said vaporizer pan means vaporizes excess oil droplets for subsequent burning in the mid portion of the chamber means thereby providing for maximum BTU output.

Waste Oil heater for burning petroleum oil comprising a storage tank including a filler opening, a heat deflector supported on top of said tank, a combustion chamber supported on said heat deflector, a spaced meshed safety screen surrounding the combustion chamber and affixed to the combustion chamber, a combustion air wand having a closed annular channel, the channel being centrally supported in the combustion chamber, the channel including a small and large number of air holes vertically spaced from each other in inner and outer surfaces of the channel for providing combustion air, a diffuser plate including a plurality of holes horizontally spaced from each other, the diffuser plate being circumferentially affixed between the small and large number of holes of said closed annular channel for mixing air with gases forming a resultant vapor which burns, a pipe supporting said air wand-diffuser and connected between said closed annular channel, through said combustion chamber and to a blower supported outside of said combustion chamber, an oil output tube having one end positioned through said combustion chamber adjacent to said center of the closed annular channel and another end connected to a submersible pump in said storage tank, a vaporizer slightly above the heat deflector and affixed to the heat deflector in said combustion chamber, a cam-locked access door in a lower front portion of said combustion chamber for providing access to said vaporizer pan, a vent hole in an upper rear portion of said combustion chamber, a removable top cover in a top of said combustion chamber, and an electrical wall thermostat connected between said pump and blower and a power source whereby said oil pump drops oil into said center of said air wand which has a stream of moving air flowing through the plurality of holes in said closed annular channel after being preheated in said pipe, and the vaporizer pan providing for initial combustion and subsequent boiling of excess petroleum thereby generating maximum BTU from said petroleum.
