Vaporizing Burner
- HORIZONTAL AIR INTAKE KITS STAGE I AND II
The vaporizing type burner system is very simple to assemble and operate. Fuel can be burned which is unsuitable for fully automatic atomizing burners.
The stage 1, 2 and downdraft kits were developed for conversion of double barrel woodburning heaters to use waste oil as a fuel. Other heaters or boilers can be retrofitted also.
How it works: A combustion chamber built up from used car brake drums with a cast iron skillet in the bottom is heated up. The oil is delivered by a metering pump through a nozzle located above the combustion chamber. Most of the oil falling down into the combustion chamber vaporizes and burns up before hitting the pan in the bottom. Air necessary for combustion is delivered by a blower placed outside the barrel. The air enters the space between the two middle brake drums and the manifold jacket, is heated to a very high degree and blown through air holes inside the brake drums to the inside of the chamber where it mixes with oil vapors. The combustion is very thorough and clean. The mixture is adjusted for smoke and odor free combustion by adjusting the speed of the metering pump and the blower.
Very long burns without cleaning are possible.
The burner is started by placing an oily rag or some pieces of wood in the pan. Attention free operation is reached very quickly.
Capacity: about 50,000 BTU to 120,000 BTU
Electrical service: 110V, 6” flue pipe, 40 mesh oil strainer.
The DOWNDRAFT configuration makes it possible to obtain higher heat output using the same control box and blowers as the horizontal intake system.
ADVANTAGES of the downdraft system:
1) higher output: 70,000BTU -1/2 gal./HR. to 175,000 BTU – 1.2 gal./HR. 2) Easier cleaning 3) Any kind or size of a brake drum can be used 4) No drilling of air holes in the brake drums, no manifold jacket used, no vaporizing pan needed Owners of the horizontal air systems can convert to downdraft by purchasing a downdraft kit.
OPERATION: The fuel pipe is coaxial with the air tube. The combustion air and the fuel delivery are infinitely variable turn of the knob type independent, allowing excellent heat output and air/fuel mixture control. The fuel stream breaks up into droplets upon hitting the head of the cascade assembly. Most of the fuel burns completely without reaching the bottom of the combustion chamber. An annular groove in the base of the cascade assembly retains unburned fuel until it is vaporized, which occurs mostly only during the starting period.
STARTING: A short preheat is necessary. An oily rag and some pieces of wood are needed. Attention free operation is reached very quickly.
CLEANING: Reach in, remove the cascade assembly. The ashes separate from the assembly with a few chipping hammer blows. Other factors pertaining to operation remain similar to the horizontal intake system.
CAPACITY: about 70,000 to 180,000 BTU, 6” flue pipe, 40 mesh oil strainer.
