Process for superheated steam

Disclosed is a process for the preparation of superheated of steam by transferring heat from at least a fraction of a high pressure steam to a lower pressure steam to produce a superheated, lower pressure steam. The high pressure steam can be generated by recovering heat from a heat producing chemical process such as, for example, the partial oxidation of carbonaceous materials. The lower pressure steam can be generated by reducing the pressure of a portion of the high pressure steam or by recovering heat from one or more chemical processes. The superheated, lower pressure steam may used to generate electricity in a steam turbine, operate a steam turbine drive, or as a heat source. Also disclosed is a process for driving a steam turbine using superheated steam produced by the process of the invention.

Method and system for combing solar energy thermal power generation with biomass power generation

The invention relates to a method and a system for combining solar energy thermal power generation with biomass power generation. When the method is used for generating electricity in the daytime (a fine day), one path of heat transfer oil heated in a heat collection field passes through a heat exchanger to ensure that counter-flow water is heated up into superheated steam at the temperature of between 360 and 380 DEG C; and the other path of the heat transfer oil heated in the heat collection field passes through the heat exchanger to heat up a fused salt so as to perform energy storage. The water heated in a water cooled wall of a biomass boiler is changed into steam which enters a steam header and a steam-water separator, then is heated to the temperature of between 535 and 545 DDEG C after being sent into a super-heater of the boiler together with the steam at the temperature of between 360 and 380 DEG C, and then is supplied to a steam turbine to drive a generator to finish the power generation process. During receiving electric valley adjustment, the biomass boiler maintains the minimum stable combustion state. The self power generation of the method and the system can be used for supplying electricity to an electric heater in a fused salt heat storage system to heat the fused salt and perform secondary energy storage for a fused salt heat tank. During the night, or when a solar energy condition is not good, the heat energy stored in the fused salt is released by the heat exchanger to generate electricity.

PCT No. PCT / JP97 / 00573 Sec. 371 Date Jan. 12, 1998 Sec. 102(e) Date Jan. 12, 1998 PCT Filed Feb. 27, 1997 PCT Pub. No. WO97 / 32161 PCT Pub. Date Sep. 4, 1997According to the present invention, boiler water is pressurized so that its boiling point is set at approximately 200 DEG C. to 320 DEG C. The boiler water is heated in at least two stages. Thermal energy of gases containing chlorine compounds is used to heat the water to its boiling point. Thermal energy of gases which do not contain chlorine compounds is used to heat the water from its boiling point until superheated steam of a given temperature is generated. The heating which uses the thermal energy of gases containing chlorine compounds is accomplished using the thermal energy from the combustion of pyrolysis gases obtained from a pyrolysis means in which waste material is supplied into a chamber containing a fluidized bed medium which has been heated to at least 300 DEG C., and a pyrolytic reaction is induced. The heating which uses the thermal energy of gases which do not contain chlorine compounds is accomplished using the thermal energy obtained from a char combustion means to combust char in which a char mixture consisting of unpyrolyzed residue and fluidized bed medium removed from the pyrolysis means is fluidized by a stream of air, and the unpyrolyzed residue is combusted.
