Problems solved by technology

Present processes release large volumes of gas into the atmosphere, resulting in a loss of energy, especially the latent heat of any condensable vapor, resulting in low thermal efficiencies.

[0058] Combustion / incineration of materials that produce water vapor, e.g. wet combustibles. While some emphasis is on biomass fuels, the process could have application to the combustion of (a) solid / liquid fossils fuels; (b) fuels intermediate between the two i.e. lignite (brown coal), peat, etc, where the high moisture content is a deterrent to their use; (c) Diverse fuels, such as Tire Derived Fuel (TDF), and various sludges, etc. (2) Diverse processes such the smelting of ores; wet oxidation; chemical, electrochemical, metallurgical processes (blast furnaces), and intermediary operations such as: drying; stripping, extraction; boiling and the like.

[0059] In FIG. 3, there is shown an arrangement wherein the increase in pressure of the source process cannot be carried out, then the gases from the source process are turbo-compressed to the desired pressure, with the temperature increased by the compression. For example in the drying of pulp or paper, enormous quantities of air and...

Abstract

The invention relates to gaseous sources from which to reclaim energy using a pressurized direct contact heat exchanger, and in particular, those sources containing a condensable vapor. While the main applications involve water as the condensable vapor, the process is applicable to other vapors, e.g. those in the chemical and petroleum industries where various organic solvents are used. The reclaimed energy can be in the form of a hot fluid, process steam and or electricity. It has particular application to: a pressure combustion furnace and the DOE's Clean Coal Technology; the combustion of wet fuels (biomass, peat); pulp & paper; electrolysis of alumina or water; detoxidation, thermal depolymerization, enhanced oil recovery (and sequestering of carbon dioxide), phytotechnology,
