Abstract
A steam generator a steam turbine driving unit, designed for the use of gaseous propellant, especially hydrogen, containing a gas supply unit, an air feeding unit (20), a steam generator (1) and steam turbine (77). The gas supply unit is provided with a supply container (8), a gas container (18), and with fittings used for filling up and gas supply. The air feeding unit is provided with instruments regulating air flow, and with an air filter (25). The steam generator is provided with a combustion chamber (1) having a ceramics wall, and the cooling pipes (31) adapted for steam generation are arranged in the combustion chamber (1). The steam turbine (77) is driven by the steam obtained from the cooling pipes (31) used for steam generation, and its shaft (36) represents the power output.
Claims23
A steam turbine type propulsion unit for use with gaseous fuel, comprising:
- a gas supply unit, comprising a supply container (8), a gas container (18) connected to the supply container, a filling duct connected to the supply container, and a gas supply duct connected to the supply container;
- an air feeding unit (20), provided with instruments regulating air flow, the air feeding unit being supplied with air through an air filter (25);
- a steam generator (1), comprising a combustion chamber surrounded by a ceramics wall (35a), said steam generator being connected to the gas supply unit and the air feeding unit (2), said steam generator having steam generating cooling pipes (31) adapted for steam generation disposed within the ceramics wall;
- and
- a steam turbine (77) connected to the steam generator and driven by steam obtained from the steam generating cooling pipes (31), the steam turbine providing power output through a shaft (36).
A steam generator propelled by gaseous fuel, said steam generator (1) having a combustion chamber surrounded by an internal ceramics wall (35a) having a frustum shape;
- the ceramics wall (35a) having cooling pipes (31) used for steam generation and arranged in a spiral, the steam generating combustion chamber (1) having a heat insulating coating (35b) on its exterior, a wider end of the combustion chamber (1) being connected with jets (23) arranged practically in a plain sheet, another end being connected with a pipe (2) ducting combustion products.
