Use of renewable energy like solar, wind, geothermal, biomass, and hydropower for manufacturing combustion air for a fossil fuel burner and firebox

Abstract

Invented is a method of making combustion air for a fossil fuel burner, as a coal burning power plant, oil refinery or gas fired household appliance. Combustion air is made from solar, wind, biomass, hydropower or geothermal. A staged progression using lower cost greenhouses, or flatplates, or solarponds, feed warm air to higher cost concentrator solar collectors. Wind energy, biomass, geothermal energy heat and compress combustion air. Hydropower also heats and compresses combustion air. Solar evaporation from salt or impure water creates water or local rain for the hydropower system. Combustion air thus is made economically hot, compressed and high velocity, and placed into a heavily insulated pipes for long distance transmission to a distant power plant.

Description

PRIOR ART[0001]Methods of making hot and warm air from renewable energies abound. Commonly referred to as solar, wind, biomass, or geothermal, or tidal energy; renewable energy can make hot air, compress air, and blow air. Nix in U.S. Pat. No. 5,308,187 (issued May 3, 1994) outlines a method of reducing fuel consumption for a fossil fuel burner. Air is pre-heated by solar energy, using a parking lot like surface. The transparent clear covering heats an opaque thermal conducting mass. This thermal conducting mass then transfers heat to underground pipes. The hot air is sucked into a firebox in a coal burning power plant. The pre-warmed air reduces the amount of fuel that needs to be burned. The invented device improves upon Nix, to include higher temperatures, and higher compression of the air. This makes for a more efficient combustion, reducing the amount of carbon dioxide created, and also reduces drastically the amount of fossil fuels needed.[0002]Cottle in U.S. Pat. No. 608,755 ...

Benefits of technology

[0108]The invented device improves upon Nix, U.S. Pat. No. 5,308,187 (issued May 3, 1994). Nix claims a system of heating air with solar energy and for supplying air to a fossil fuel burner. However, the system described only supplies air in the low temperature range. To adequately power a large-scale power plant, a coal burning power plant will need temperatures on upwards above 750 F degrees. Often the interior of a firebox of a coal power plant can approach 1,000 F degrees. By pre-heating air to high
