Modularized, superheated steam generators comprise a steam module (46), a thermocouple module (41), and an electrode module (45) assembled within a containment enclosure (66). The multi-stage steam module (46) comprises a plurality of first stage pressure vessels (77) surrounding and feeding a second stage pressure vessel (78). The steam module (46) is coaxially surrounded by insulation (48) disposed within a cylindrical shroud (72). The electrode module (45) radiantly heats the steam module with resistive heating elements (119). The thermocouple module (41) includes thermocouples monitoring first stage temperatures within and between pressure vessels (77). PLC computer SCADA software (600) operates the generators. Thermocouple data is analyzed to control heater temperatures, the water feeding system (340), and outputted steam temperature. PLC software (600) provides operating logic (602) establishing a start up subroutine (602), a ramp up subroutine (603), a steady state subroutine (605), and a shut down subroutine (606). |

In a coal fired power plant (17) incorporating a feed-water heater (10), energy is provided to the feed-water heater by pumping geothermal hot water through supply and return pipes (15, 16) from a geothermal reservoir (14) located beneath an adjacent coal seam (19). The coal seam acts as an insulating layer, increasing the temperature of the geothermal reservoir (14). Solar heat collectors (21) and (25) can also be provided to boost the temperature of the geothermal hot water and/or the feed water. |

The invention relates to a method for heat energy transmission between a gaseous, warmer medium on one hand and a liquid, colder medium on the other hand. In order to provide an improved method for heat energy transmission, the invention suggests a method in which the liquid and the gaseous media are passed by each other using a plate heat exchanger, wherein the gaseous medium is cooled down and the water contained therein is condensed out, while the heat energy released due to condensation is transferred to the liquid medium. |

A method of recovering heat energy during blowdown of a steam boiler is described wherein thermal energy is recovered both from flash steam produced by blowdown water and the blowdown water itself. The flash steam is preferably condensed in the feedwater (or any open vented water tank) so as to recover the water volume of the flash steam in addition to its heat energy. |

A feedwater heater for a steam generator or heat recovery boiler or waste heat boiler through which hot gases pass includes two sections which are located side by side so that the temperature of the hot gases at the upstream face of each section is essentially the same. The feedwater flows through a heat exchanger before entering the first section, and here it is heated by water flowing from the upstream face of the first section to the downstream face of the second section. The arrangement is such that all tubes in the two sections remain above the dew point of the hot gases, so that water does not condense on the tubes and unite with oxides of sulfur to form sulfuric acid which will corrode the tubes, yet substantial temperature differentials exist between the water in the sections and hot gases as the gases pass through the sections. |

In a power plant having a boiler for heating a fluid to form a gaseous phase, a power generator for generating electrical power from the gaseous phase, a condenser for condensing the gaseous phase after the gaseous phase has passed through the power generator, a liquid ring pump for evacuating uncondensed gaseous phase from the condenser, and a chiller for cooling seal liquid discharged from the liquid ring pump for re-use in the liquid ring pump, apparatus is provided for utilizing the heat generated during the operation of the chiller to heat a predetermined portion of the fluid supplied to the boiler, thereby reducing the amount of heat which must be provided by the boiler to form a gaseous phase of the fluid so that electricity can be generated. The efficiency of the power plant is thereby increased. |
