This patent application has not been assigned to a company or institution.
The following quote was obtained by the news editors from the background information supplied by the inventors: "The present invention relates to fossil fuel combustion and, more particularly, to controlling pollutants and greenhouse gassed created by fossil fuel combustion. Fossil fuel combustion is a major contributor to greenhouse gas emissions and a significant contributing factor to global warming, or climate change. Banning the use of fossil fuel resources is not a viable solution to control the emission of greenhouses, because many developing and third world countries have no alternative source of energy. At the same time, pollution has no respect for international boundaries and touches all of us sharing the planet.
"The present invention provides an apparatus and method for cleaning flue gasses of industrial or domestic coal and gas furnaces. Burning fossil fuels such as coal, oil and gas results in serious air pollution. The manner in which conventional smoke cleaners, called scrubbers, operate is well known. Systems known as wet scrubbers shower lime water on the rising flue gasses to precipitate or physically remove particulates from the exhaust gasses. Venturi type scrubbers mix lime water and smoke in a confined space. Dry scrubbers utilize chemicals and electrostatic precipitators to intercept and remove pollutants by using opposing magnetic fields. Regardless of the scrubber type, subsequent to their treatment, all such treated exhausts are released into the atmosphere.
"Present technologies are not perfect and can be improved by diminishing the imperfections that are presented in their application. The improvement of the present invention can be applied to wet scrubbers showering flue gases with lime water or chemical, to Venturi scrubbers mixing flue gases and liquid scrubbers in a restrictive passage, to resonator scrubbers in which the flue gas is cleaned by using jets of vapor, water or chemicals that are intercepted by sonic shock waves, to electrostatic precipitators where opposing polarities precipitate polluting particles.
"For example precooling the exhausts is imperative because hot flue gas rise so rapidly that the duration of time that the exhausts contact and engage with the respective treating solution, its contact time, is very short, with insufficient time to absorb all the contaminants present in the exhausts. This is particularly the case with wet scrubbers, but this condition is also present with Venturi scrubbers that also suffer from short contact time.
"Another significant problem with Venturi scrubbers is presented by the very confined area where the mixing of exhaust gasses and the treating solution. This limits the mixture of exhaust gasses to treating solution to a ratio of 1 to 1, which allows some contaminants to escape untreated.
"According to aspects of the present invention essentially resides in providing a different and more efficient method and plant to clean flue gas caused by combustion of fossil fuels and to avoid shortcomings and inefficiencies encountered in prior art.
"Leaving coal underground and unutilized presents a wasted asset. As from the story by Jesus, who praised the two servant who used the talents received and profited and condemned the servant who dug a hole in the ground and wasted the talent received. Progress is driven by faith not by fear. Coal has a reason to be on earth that is for it to be used wisely for the benefit of all. In fact electricity consumption generated by coal and standard of living go hand in hand, if one increases so does the other.
"Two groups of contenders occupy the media debate on pollution. However, the proverbial elephant in the living room that nobody seems to see, presents the greatest cause of pollution: it is that only a small part of the heat created by the combustion of fossil fuels is actually used, the rest is wasted causing a greater pollution than any other source.
"As can be seen, there is a need for improving the efficiency of fossil fuel combustion so that we would only need half of the plants in use and still generate the same amount of electricity and yet output only half of the pollutants."
In addition to the background information obtained for this patent application, VerticalNews journalists also obtained the inventor's summary information for this patent application: "In one aspect of the present invention a vacuum chamber boiler is provided which includes an elongate body having a sidewall defining a cavity therein. The cavity has a sealing plate extending across the cavity and sealingly engaging with an interior surface of the sidewall to define a boiler chamber in a lower portion of the cavity and a vacuum chamber in an upper portion of the cavity. A smokestack is substantially contained within the boiler chamber and extends from a first opening at a bottom of the boiler chamber to a second opening in the sealing plate. The smokestack is adapted to communicate exhausts received from a furnace through the first opening and the second opening, where the second opening is in communication with the vacuum chamber. The boiler is adapted to receive a source of liquid for producing steam, and the vacuum chamber is adapted to receive a vacuum source applied to an outlet of thed vacuum chamber.
"In preferred embodiments of the invention the smokestack is articulated within the boiler chamber. In other aspects of the invention the smokestack is articulated along a width, a length and a height of the boiler chamber. In certain preferred aspects of the invention, the length of the smoke stack within the boiler chamber is selected such as to approach equilibrium of the exhausts temperature at the sealing plate opening with the temperature of the source of liquid producing for producing steam.
"In other aspects of the invention, the vacuum source comprises a vacuum pump, connected to the vacuum chamber outlet via a conduit, wherein the vacuum pump is submerged in a circulating source of cooling fluid contained within a vacuum station external to the vacuum chamber boiler. In preferred embodiments of the invention, the vacuum source comprises a plurality of vacuum pumps submerged in the vacuum station and each vacuum pump is connected to the vacuum chamber via a separate conduit.
"In yet another aspect of the invention, a bath scrubber is disclosed and claimed which includes a main chamber defined by an outer wall of the bath scrubber. The main chamber has a lower portion adapted to contain a volume of a of chemical water bath to a fill line in the main chamber and an upper portion defined above the fill line. An inlet defined in said lower portion is adapted to receive exhausts from fossil fuel combustion contained in a furnace. The bath scrubber further includes a perforated plate extending across the lateral and longitudinal aspects of the main chamber beneath the fill line and has an outlet defined in the upper portion which adapted to evacuate exhausts from the bath scrubber. In other aspects of the invention the bath scrubber further comprises a plurality spray nozzles projecting into the upper portion of the main chamber. A pump may also provide a pressurized source of chemical water to the spray nozzles.
"In other aspects, the bath scrubber is provisioned with a plurality of ultrasonic emitters positioned proximal the perforated plate and the emitters are arrayed to foment the exhausts within the chemical water bath.
"In yet another aspect, the bath scrubber includes a vacuum source connected to the outlet. The vacuum source includes: a vacuum pump, connected to the outlet via a conduit and the vacuum pump is submerged in a circulating source of cooling fluid contained within a vacuum station external to the bath scrubber. In preferred aspects, the vacuum source includes a plurality of said vacuum pumps submerged in the vacuum station and each vacuum pump connected to the vacuum chamber via a separate conduit.
"The invention also includes an apparatus for cleaning flue gas, comprising: a vacuum chamber boiler; a bath scrubber: and at least one vacuum station external to said vacuum chamber boiler and the bath scrubber.
"These and other features, aspects and advantages of the present invention will become better understood with reference to the following drawings, description and claims.
