Abstract:
Heat and electricity generating apparatus (201) for a boiler system (202) for use in a residential or small-scale building. The heat and electricity generating 5 apparatus (201) comprises a centrifugal air compressor (203), a turbo-expander (204) and an electric generator (205) operatively connected by a rotatable drive shaft (206) and further comprises a high-pressure combustor (207), a first air-to- air heat exchanger (208), a second air-to-fluid heat exchanger (209) and a diverter gate (222). In operation, a method of heat transfer is performed in which combustion product gas issued by the high-pressure combustor (207) is passed to the first heat exchanger (208) either through the turbo-expander (204) or directly, to heat compressed air issued by the centrifugal air compressor (203) prior to entry into the high-pressure combustor (207), and is then passed through the second heat exchanger (209), to heat a heat-conveying fluid.

Abstract:
The present invention comprises a highly supercharged, regenerative gas-turbine system. The gas turbine comprises a compressor, a regenerator, a combustor, and an expander. A pre-compressor pressurizes air going into the compressor section of the gas turbine. A cooler lowers the temperature of the air going into the compressor. The compressor pressurizes air, which then flows through the regenerator, which heats the air before it enters the combustor. The combustor further heats the air which then flows through the expander and then the regenerator. A post-expander is preferably located downstream of the regenerator. The post-expander is a second expander that receives high-pressure gas exiting the regenerator. The post-expander preferably drives the pre-compressor. The preferred pre-compressor and post-expander are toroidal intersecting vane machines (TIVMs), which are positive-displacement rotary devices. Numerous alternated embodiments of this basic system are described.

The HRSG is formed by a plurality of heat exchangers (25, 29, 32) including steam/water drums (26, 30, 33), each having a surface blowdowns connection (40-42, 53-56). The HRSG feeds a steam turbine (12).
Abstract:
A microturbine power generating system includes a primary compressor, an electrical generator and a turbine that can be rotated as a unit. Hot, expanding gases resulting from combustion are expanded through the turbine, and the resulting turbine power is used for powering the electrical generator. The microturbine power generating system further includes an auxiliary compressor that is driven by the turbine power. During operation of the system, a small portion of air can be bled off the primary compressor and further compressed in the auxiliary compressor to provided an auxiliary supply of pressurized air.

Abstract:
A disc turbine engine with a multi disc engine where each disc engine includes a turbine blade, a low-pressure compressor blade, a high-pressure compressor blade, and a bearing. Each disc engine runs freely and individually, counter-rotating directions from each other and around a fixed shaft. Each disc engine has its own cooling system. The compressor's blades act as cooling fins for the turbine blade. A coolant, such as liquid hydrogen is used to fill the hollow body of the high-pressure compressor, the hollow body of the lower pressure compressor, and the hollow body of the turbine blade with a connection chamber in between the hollow blades as a sealed system. The nozzle is filled with a coolant inside the hollow bodies of the nozzle and guide fan as a sealed system.
