The Thermal-Watt Furnace
The Thermal-Watt furnace consists of a rotary type engine and an electric generator. It also has a very efficient heat recovery system.
Rotary engines do not have pistons, valves, cams, etc. They consist of only two moving parts, a rotor and elliptic shaft. The life expectancy of a rotary engine is 10 times that of a piston engine.
When an engine burns fuel, it does so with much more precision than an open flame. First the fuel is passed through a finely tuned carburetor and mixed with air in precisely the right ratio. This allows a controlled “ lean burn.” This means less fuel is used to heat the inert gases as compared to an old style furnace, which uses an uncontrolled, open flame. An open, or “lazy” flame burns with an inner core of flame which is too rich and an outer surface which is too lean to create efficient combustion. By contrast, an engine mixes the fuel /air and captures it in a combustion chamber, burning it in ideal conditions to maximize efficiency.
An engine also compresses the fuel-air mixture, so combustion takes place under high pressure. The pressurized molecules in the “compression stroke” greatly accelerate and enhance the chain reaction (pyromation). The chamber pressure is greatly increased, driving the generator and resulting in two sources of energy achieved from one source of fuel. The post combustion temperatures are equivalent to an old style lazy flame furnace. At first glance, it appears to violate the laws of physics. Actually, the thermal Watt furnace simply takes advantage of physics that are not available in the old “lazy flame” furnace design. The second law of thermal-dynamics says you can use the same heat more than once. The Thermal Watt unit does just that to “gift” electricity to the homeowner.
But, there are still more laws of thermo-dynamics to consider… and utilize. When a hydrocarbon burns it produces water. The elevated temperatures turn the water to steam, absorbing about 10 per cent of the available energy. Recapturing this energy is only accomplished by reducing the exhaust below the condensation point of water. The Thermal Watt furnace does this with a “forced exhaust.”
A normal furnace or boiler doesn’t capture this latent heat. The exhaust draft system of normal furnaces and boilers requires temperatures to remain above condensation point, allowing this energy to escape to the atmosphere.
Thermal Watt furnaces utilize the very latest and most efficient energy technology in the world. Various types of generators are employed in Thermal Watt units, depending on which model best suites your needs. In all cases the generators are the brushless, single bearing type, using a sealed maintenance free bearing with a life of 30 years. The life of the generator itself is unknown. The original generators are still running at Hoover Dam.
Our unique heat recovery system is the most efficient on the market. Virtually all of the heat from the engine and exhaust are captured. The overall efficiency of the Thermal-Watt furnace is above 98% which means in most cases it will provide all your annual electricity needs without increasing your heating costs..
In other words, free electricity.
