摘要:
An apparatus for measuring six-degree-of-freedom motions by using three-facet reflector, the six-degree-of-freedom motions of an object being measured by using the laser beam proceeding from a laser light source, comprising: a multiple facet reflector in the form of a trigonal pyramid, the multiple facet reflector being fixed on the object for measurement and able to reflect the laser beam in three directions; three position-sensitive detectors for measuring the position and intensity of the laser light points formed on their surfaces, with the movement of the multiple facet reflector, and then providing output signals; and a controlling section for analyzing six-degree-of-freedom motions of the multiple facet reflector by using the position and intensity of the laser light points output from the three position-sensitive detectors. (FIG. 4).
摘要:
Disclosed is a triple swirl gas turbine combustor using various fuels such as coal gas, DiMethyl Ether, and waste gas generated in an ironworks in a gas turbine. The triple swirl gas turbine combustor combusts three different fuels simultaneously or individually and various fuels such as LCV gas and HCV gas so that fuel flexibility can be improved. Swirl generated in a second swirler of the triple swirler is reversely jetted to increase a mixing degree of a fuel-air mixture and an intensity of a turbulent flow so that combustion efficiency can be increased, harmful exhaust gas can be reduced and vibration can be reduced.
摘要:
Disclosed herein are a fuel nozzle of a gas turbine combustor for dimethyl ether (DME, CH3OCH3) and a design method thereof. The fuel nozzle includes a pilot fuel injection hole formed at the center of the nozzle and a plurality of fuel injection ports formed at equiangular positions around the pilot fuel injection hole to inject DME. Each of the fuel injection ports includes a pair of upper and lower DME injection orifices communicating with a fuel-air mixture injection swirler. The upper DME injection orifice becomes gradually wider, whereas the lower DME injection orifice becomes gradually narrower. Thus, DME can be optimally combusted in the gas turbine combustor, thereby achieving cost reduction of power plants, enhancement in reliability of the power plants, and diversification of usable fuel.
