    摘要： A high temperature steam valve has a valve casing including a main steam inlet, a main steam outlet and a valve chest. The high temperature steam valve also has a valve seat positioned in the valve chest, a valve element facing the valve seat, and a valve rod slidably penetrating the valve casing to drive the valve element. A cooling steam hole is provided to surround a valve-rod penetrating portion of the valve casing. Cooling steam can be poured into the cooling steam hole from outside through a cooling steam inlet hole and steam having finished heat exchange can be exhausted from a cooling steam outlet hole into the valve chest. The sliding portion between the valve rod provided in the valve-rod penetrating portion of the valve casing and bush is cooled to prevent oxidized scale from depositing on the sliding portion.

    摘要： A turbine system and method for power generation has an electric generator, a reformer, a cooler, a fuel compressor, an air compressor, a combustor, a turbine, an evaporator. The reformer reforms fuel containing a mixture of hydrocarbon gas and steam to produce hydrogen and carbon dioxide. To enhance reformation, the reformation is carried out under pressure at 7 ata or less. To aid compression, the cooler cools the reformed fuel before the compressor compresses the reformed fuel. The combustor burns air compressed by the air compressor, which is driven by the turbine, and the reformed fuel received from the fuel compressor to generate hot gas. The turbine receives the hot gas from the combustor and drives the generator to generate electricity. The reformer receives the hot gas discharged from the turbine as a heat source to heat the fuel and chemically reform the fuel.
