Power generation equipment (10) comprises a compressor (11,12) into which finely dispersed water is directed. Air compressed by the compressor (11,12) is directed into combustion equipment (13) where it is mixed with steam and fuel before combustion takes place. The resultant combustion products pass through two turbines (14,15), the second of which (15) is a power turbine. The exhaust efflux from the power turbine (15) is then cooled to such an extent that its pressure falls to below atmospheric pressure. The carbon dioxide is removed from the efflux by means of a sequestration membrane (33) before the pressure of the efflux is raised to above atmospheric pressure by a further compressor (16) driven by the power turbine (15). The equipment (10) is very efficient and produces low levels of pollution.
Power generation equipment comprising air compression equipment, means to inject finely dispersed water into the air intake of said air compression equipment, combustion equipment for mixing air compressed by said air compression equipment with a suitable fuel and supporting the combustion of that mixture, turbine equipment to receive and be driven by the exhaust products of said combustion and in turn to drive said air compression equipment, power turbine equipment to receive and be driven by the exhaust efflux of said turbine equipment, heat exchange equipment positioned to receive the exhaust efflux of said power turbine equipment and place that exhaust efflux in heat exchange relationship with water to thereby cool that exhaust efflux and generate steam from said water, means to substantially remove carbon dioxide from the efflux exhausted from said heat exchange equipment and additional compression equipment driven by said power turbine equipment and positioned to receive and compress the exhaust efflux from said carbon dioxide removal equipment, said steam generated from said water in heat exchange relationship with said turbine exhaust efflux being directed to said combustion equipment to enhance the combustion process sustained thereby.
