FIELD: transport.

SUBSTANCE: invention relates to navy exploiting high-navigability and high-speed vessels with power plants running on hydrogen fuel and the product of thermal dissociation of steam, that is, hydrogen and oxygen. Note here that sweet water stored in tanks is used as a heat carrier. This vessel comprises surface hull mounted at streamlined supports of underwater hulls, starting steam plant arranged in surface hull, sweet water tanks, main power plants with steam condensers to use sweet water as power carrier to produce useful power. Said power plants include gas turbine plant and steam plant engaged by shaft with electrical generator connected in electrical protection hardware. Steam units running of used hydrogen and oxygen of thermal dissociation gas turbines are connected via steam lines with steam collectors and plasma chemical heaters of said main power plants and refrigerators for cooling of said used hydrogen and oxygen. Steam units are connected to cooling system running on liquid metal heat carrier of the main power plants connected to steam turbines connected to electrical generators connected to switchboards and to capacitors. Plasma chemical heaters and reactors with their power supplies, motors connected with screw propellers are arranged in underwater hulls. It differs from known designs in that thermal dissociation gas turbine to produce useful power, hydrogen and oxygen incorporates plasma chemical heaters arranged regularly in circle to heat steam to temperature over 2000°C.Said plasma chemical heaters are connected to power supply and connected, on one side, via valve gear with high-temperature and high-pressure steam collector and, on opposite side, with reactors for thermal dissociation of steam to produce hydrogen and oxygen their temperature exceeding 2500°C. Threes are connected to power supply including HF generators and capacitor bank connected with diverging nozzles and cylinders of wave compressors. The latter incorporate water or liquid metal injectors connected to gas turbine fitted on the shaft engaged with electrical generator. Said turbine is provided with discharge pipe to force used hydrogen and oxygen into steam unit. Or, thermal dissociation gas turbine incorporates plasma chemical reactors for thermal dissociation of steam and production of hydrogen and oxygen with temperature over 2500°C and high pressure. Said reactors are connected via valves gears with high-pressure and high-temperature steam collectors on one side and, on the other side, with cylinders connected to aforesaid diverging nozzle and cylinders of wave compressors provided with water or liquid metal injectors connected with gas turbine. Said turbine is provided with discharge pipe to force used hydrogen and oxygen into steam unit. Also, it differs in that plasma chemical heaters, plasma chemical reactors for thermal dissociation of steam and production of hydrogen and oxygen with temperature over 2500°C, or plasma chemical reactors, diverging nozzles and wave compressor cylinders are provided with jackets for circulation of aforesaid coolants for cooling reactors for thermal dissociation of steam and production of hydrogen and oxygen with temperature over 2500°C and high pressure. Also, it differs in that plasma chemical heaters or reactors incorporate housing with jacket, cover and cap and electrode-cathode secured in housing, in electric insulation ply. Said cathode communicates with cooled nozzle, the anode, arranged at the angle to axes of said reactors. Or, plasma chemical heaters or reactors are arranged in one unit with light ionising additive injectors built therein and arranged in the axis of reactors. Note here that valve mechanism with high-pressure-and-temperature inlet valve is arranged at plasma chemical heater housing. Also, it differs in that valve mechanism comprises steam feed pipe and discharge valve with constrictor and spring. The latter is composed of tubular slider plugged on one side and fitted in cylinder secured at the housing. Said cylinder has openings in it and inlet valve tubular slider walls to intake steam in plasma chemical heater or reactor. Its differs in that said reactor is made of ceramic material with circular inductor arranged thereon and composed of copper pipes with jacket for circulation and cooling of reactor walls and inductor by water. Also, it differs in that steam plat for combustion of hydrogen and oxygen incorporates axial compressor connected with long pipes, combustion chambers arranged regularly in circle. They include injectors to ignite hydrogen in oxygen by injection of gaseous jets of conducting fluid thermal dissociation products with diverging nozzles and wave compressor cylinders connected to steam turbine. The latter is fitted on shaft engaged with electrical generator and incorporates branch pipe to discharge used steam into condenser. Besides, it differs in that said injector comprises casing with conducting liquid feed pipes. Said pipes are connected to cylindrical channels arranged inside the casing in insulating material ply. Electrodes connected to pulse generator are arranged on one side of said channels while, on opposite side, nozzle are arranged directed at the angle to each other and communicated with blast chamber of injector that has perforated bottom for escape of gas jets.

EFFECT: clean atmosphere.
