Definitions

  • the present invention relates to a reaction-type turbine using steam, gas, or compressed air.
  • a steam turbine is one of motorized devices to convert thermal energy from pressurized steam into mechanical motion. Due to low vibration, great efficiency, and high-speed and large-horsepower, the steam turbine has been widely used as a main engine for thermal power plants and ships.
  • the steam turbine injects high-temperature and high-pressurized steam produced by a boiler from nozzles or fixed blades, and expands the steam to generate a steam flow at high velocity. Then, the high-velocity steam flow is directed to strike turbine blades, which results in impact or reaction that drives a shaft to rotate.
  • the steam turbine may include a plurality of nozzles to convert thermal energy from steam into velocity energy and a plurality of turbine blades arranged in parallel to the nozzles to convert the velocity energy into mechanical motion.
  • pressurized steam flowing into a steam chest from a boiler expands, rotates a turbine shaft coupled to the turbine blades as passing through the nozzles and the turbine blades, and then moves to an exhaust chest.
  • the steam in the exhaust chest is sent to a condenser to be cooled, and then may be returned to the boiler by a feedwater pump or may be exhausted to atmosphere.
  • the conventional steam turbine as described above is characterized in generating rotation torque by a flow of a high velocity steam striking turbine blades that rotate at a high speed, and thus when condensate water is mixed with the steam, the turbine blades may be damaged.
  • the steam flowing into the turbine blades is required to be managed, avoiding the condensate water being generated.
  • the turbine blades need to be manufactured with expensive materials, and assembling such turbine blades is complicated, thereby increasing the manufacturing cost.
  • a force to rotate the turbine axis is in proportion to momentum of steam entering the turbine blades, and the momentum of the steam is determined by various factors, such as the number and the surface area of the turbine blades and an inlet angle of the steam.
  • the steam striking the turbine blades changes velocity and direction, designing the shapes and angles of the blades in consideration of these changes increases design complexity, and thus there is a limitation in manufacturing a high-efficiency turbine.
  • the present invention is to solve the above-mentioned problems of the conventional steam turbine and provide a reaction-type steam turbine which can prevent component damage upon an impact by condensate water generated in steam and thus can facilitate the management of steam, allowing the use of low-cost materials and simplifying assembly process, which contributes to reduction of manufacturing costs.

  • the reaction-type steam turbine is configured such that a jet and rotating unit and a turbine shaft rotate by the repulsive force generated when steam spurts from the jet and rotating unit, so as to generate propulsion force.
  • the operating stability of a steam turbine can be maintained even when condensate water is mixed with the steam, and manufacturing costs can be significantly reduced.
  • the flow resistance of the steam is remarkably reduced or pressure leakage is prevented, thereby obtaining a low-cost and high-efficiency turbine.
