Abstract

To apply the properties of water, once vaporized, combust at a temperature above 1,500 degrees Fahrenheit, the exhaust heat from a combustion chamber and from the super-heated steam heading for cooling at a conventional power plant is to be utilized to vaporize water for combustion in the combustion chamber heated above the required temperature in order to super-heat the steam for power generation thereby reduce conventional fuel consumption commensurate with the amount of heat generated by the water-converted fuel and to utilize water to be vaporized for condensation of the left-over from the combusted fossil fuel mixed with CaCO3 so as to neutralize acidity in the waste, to prevent pollutants from air-borning and to convert the residue-air to usable gas.

The exhaust heat at a nuclear power plant can likewise be tapped for additional power generation.

Description

When the applicant of the said patent, Donald H. Choi, attended the first chemistry class at Choongang Middle School in Seoul, Korea, in 1942, the chemnistry teacher recalled insufficient water the firefighters squirted onto the fire on the main brick building of the school helped fuel the fire instead. Consequently, the building was left to burn down.

Taking a lesson from this, I tried to promote use of water as a fuel in my later years, but made no progress. In the process, however, I learned that the temperature of the steam to run the turbine at a power plant is around 1,000 decrees Fahrenheit and it had to be cooled for recycling through the cooling tower to the coil around the combustion chamber with a temperature above 1,500 degrees Fahrenheit while another exhaust heat is sent up to the air through the chimney from the combustion chamber.

I asked myself: Why not utilize the exhaust heat to convert water to fuel and feed it into the combustion chamber? Hydrogen and oxygen in water separate and burn at high temperture estimated above 1,500 degrees Fahrenheit? I convinced myself it would since the combustion chamber may provide enough space for the explosion of hydrogen. That's why I decided to apply for patent right on the utilization of exhaust heat to convert water to fuel.

If and when the exhaust heat converts enough water to fuel—high temperature steam—to operate a power plant, the converted-water-fuel may replace conventional fuel so long as the combustion chamber maintains optimum temperature estimated above 1,500 degrees F.

In the event the exhaust heat fails to convert enough water to fuel to operate the plant, it would certainly augment the conventional fuel. In such a case, the water to be heated by the exhaust heat emanating from the combustion chamber would condense the acid and other pollutants going out to the chimney. This enable to trap them for neutralization with chemical agents such as CaCo3.

When coal, converted-water-fuel and CaCO3 are combusted in the combustion chamber, gas may be generated. When soot and pollutants are removed from the outgoing exhaust, it would be usable gas for use in additional combustion chamber or for public utitlities. [0006]
