    • A power generation system that includes a heat source loop, a heat engine loop, and a heat reclaiming loop. The heat can be waste heat from a steam turbine, industrial process or refrigeration or air-conditioning system, solar heat collectors or geothermal sources. The heat source loop may also include a heat storage medium to allow continuous operation even when the source of heat is intermittent. Heat from the heat source loop is introduced into the heat reclaiming loop or turbine loop. In the turbine loop a working fluid is boiled, injected into the turbine, recovered condensed and recycled. The power generation system further includes a heat reclaiming loop having a fluid that extracts heat from the turbine loop. The fluid of the heat reclaiming loop is then raised to a higher temperature and then placed in heat exchange relationship with the working fluid of the turbine loop. The power generating system is capable of using low temperature waste heat is approximately of 150 degrees F or less. The turbine includes one or more blades mounted on a rotating member. The turbine also includes one or more nozzles capable of introducing the gaseous working fluid, at a very shallow angle on to the surface of the blade or blades at a very high velocity. The pressure differential between the upstream and downstream surfaces of the blade as well as the change in direction of the high velocity hot gas flow create a combined force to impart rotation to the rotary member.

    • An intercooled gas turbine driven powerplant (10) employing a high pressure two-pass heat exchanger (42) down stream of the final stage of compression (22) is disclosed herein. The flow of hot, highly compressed air is cooled in the first pass (54) of the high pressure heat exchanger by a counter current in-tube flow of either water (76) alone, or preferably, of a cold methane/water (76, 78) mixture. The flow of air, thus cooled, is then available, in the second pass (56) of the high pressure heat exchanger (42), to accept exhaust heat or the low grade heat, usually rejected, that is found in the heated fluid from the intercooler (36). The cool air is thus preheated, by the return to the cycle of exhaust heat, intercooler heat, and/or low grade heat from the operation of ancillary equipment prior to its entry into the combustor (48). Additionally, if a methane/water two-phase feed is used to cool the first stage (54) of the heat exchanger (42), the superheated mixture of steam and methane produced by the heat exchanger provides the ingredients to produce a low NOx fuel for the gas turbine combustor (48). Thus the first pass (54) of the high pressure heat exchanger (42) cools the high pressure discharge air flow and simultaneously generates the low NOx fuel gas (or if water alone is used, a quantity of steam for use in any industrial process). The second pass (56) of the high pressure heat exchanger (42) reheats the air flow with the exhaust heat or intercooler heat and simultaneously cools the water (or other heat transfer fluid) and returns that cold fluid to the intercooler (36) or exhaust heat exchanger. In an alternative embodiment, the dual heat exchanger (42) is positioned as an intercooler between stages of compressor (20, 22) instead of downstream of the final stage of compression (22). The first pass (54) of the dual exchanger preheats the fuel (78), which is then routed to a fuel superheater (166) in the exhaust gas stream prior to being injected into the combustor (48). The intercooled air from the final compressor stage (22) is routed to an exhaust heat recuperator (174), where it is heated prior to being injected into the combustor (48).

    • The invention relates to power engineering, more specifically to the transformation of kinetic energy of a solid flow of working medium into electric energy and can be used for wind, thermal and hydraulic power plants and for recovering the energy of thermoinductive flows from a heat recovery boiler involving direct contact between water and combustion products. The inventive device comprises a bearing skeleton (2) arranged on a base (1) in such a way it is rotatable and fixable in any position. The bearing skeleton (2) comprises tiered platforms (3, 3', 3'') provided with a separate constrictor (5, 5', 5'') and with at least one centrifugal turbine (4, 4', 4'') mounted thereon. The first input of each turbine is tangentially connected to a cylindrical body (14) of each corresponding turbine (4, 4', 4'') by means of a corresponding manifold (17, 17', 17'') and hermetically connected to the output of the corresponding constrictor (5, 5', 5'') arranged on the same stage. The output of each turbine (4, 4') is correspondingly connected to the second input of the corresponding downstream turbine (4', 4''), thereby forming a chain of series connected turbines (4, 4', 4'') and producing a successive injection of part of the working flow from said downstream turbine (4) into upstream turbines (4', 4'').
