Abrégé

The invention relates to the treatment of livestock waste and, in particular, liquids, such as those from pig farms (pig purines), in order to separate and recover fertiliser material contained therein in the form of a concentrate or solid product, for use as a fertiliser which can be transported to remote agricultural areas once the water has been separated by vaporisation. The invention also relates to the treatment of the water thus separated and to the recycling thereof in the process, providing a "zero waste" process and producing a considerable water consumption saving.

This invention advances the related state-of-the-art by eliminating the physical EO window used by electro-optical imaging infrared seekers for tactical missiles and high-altitude endo-atmospheric interceptors, widely employed in integrated defense systems. This invention increases the probability of intercepting exo-atmospheric ballistic warheads by exo-atmospheric interceptors, and eliminates the existing altitude "gap" of interception, as well as the geographical limitations posed by the mesospheric Noctilucent Clouds. The problem of protecting an imaging EO sensor from aeroheating is solved in this invention by a special purpose device which is enabled immediately after the nose cone ejection event. The role of said device is to augment the sensor fixed sunshade and cavity lengths in the forward direction, and by doing so, the resulting new cavity enables the optimal injection of an optically inert gas into the new extended cavity in front of the sensor, thus effectively blocking the entry of the compressed hot air into the sensor cavity, while simultaneously avoiding any adverse effects of inducing flow instabilities in the flow as well as the disturbance of the injected gas flow on sensor structures. Having a greater length for the hot gas to penetrate, eliminates also the penetration of suspended particles in oncoming air stream.

Abrégé

The invention relates to a method for generating energy using thermal cycles with high-pressure and moderate-temperature steam, which can be used to improve the energy and operational efficiency involved in converting heat energy into mechanical or electrical energy, using thermal cycles in which the temperature of the steam is limited to moderate values during the generation thereof. The method comprises the following steps: a) generating steam at a pressure above 65 bar and a moderate temperature below 400°C; b) expanding said steam in a steam turbine, such as to obtain steam having an intermediate pressure of between 10 and 40 bar and a moderate moisture content below 15%; c) drying the steam using a moisture separator and heating the steam; d) expanding the steam in the turbine; and e) heating boiler water used to generate the steam, using a plurality of operations comprising the extraction of steam from the turbine, in order to exchange heat with the boiler water.
