摘要： A method and a device for generating superheated steam from a working medium, which includes the following steps: feeding of a working medium in the liquid phase to a specific heating tube and temperature regulation of the specific heating tube. Furthermore, the specific heating tube is temperature-regulated with a defined amount of thermal energy, as a result of which superheated steam is formed in the specific heating tube from the working medium fed in the liquid phase, the superheated steam then departing from the specific heating tube.

摘要： The present invention intends to highly accurately control a temperature of superheated steam at a high response speed, and provides a superheated steam generator that inductively heats a heating metal body in contact with steam using an induction coil, and thereby heats the steam in contact with the heating metal body to generate superheated steam. In addition, a frequency of an AC power supply connected to the induction coil is 50 Hz or 60 Hz, and a thickness between an induction coil side surface of the heating metal body facing toward the induction coil and a steam contact surface of the heating metal body in contact with the steam is 10 mm or less.

摘要： A system includes a heat recovery steam generator (HRSG) including a plurality of evaporator sections. At least one evaporator section includes a natural circulation evaporator configured to generate a saturated steam, a once-through evaporator configured to generate a first superheated steam, a first superheater configured to receive the saturated steam from the natural circulation evaporator, and a second superheater configured to receive the first superheated steam from the once-through evaporator.

摘要： A boiler-heating assembly of a power plant has a fire chamber bounded by four vertical walls each supporting two main burners and two associated ignition burners. Each ignition burner has a cylindrical open-ended chamber with a central pipe terminating in an oil nozzle, a double-walled nozzle tube whose interspace optionally carries a mixture of air with brown-coal dust or oil set in rotation by a tangential feed, and a blower driving air axially through the chamber in an inner and an outer air stream separated by the double-walled nozzle. An annular baffle on the oil nozzle has a solid frustoconical rear surface deflecting the inner air stream radially outward across the air/fuel mixture exiting from the interspace and into contact with the outer air stream, both air streams corotating with that mixture.

摘要： Fuel and a first portion of combustion air are introduced into the furnace (10) of a fossil fuel-fired steam generator in a first zone (30) remote from the gas outlet (14) of the furnace. A second portion of the combustion air, termed overfire air, is introduced into the furnace in a second zone (60) spaced from the first zone (30) intermediate the first zone and the gas outlet of the furnace. The outlet temperature of the superheat steam conveyed through the superheater surface (24) is regulated by selectively directing the overfire air introduced into the furnace towards the gas outlet of the furnace to increase the superheat steam outlet temperature and selectively directing the overfire air introduced into the furnace away from the gas outlet of the furnace to decrease the steam superheat outlet temperature.Further, the formation of oxides of nitrogen during combustion of the fuel in the furnace is controlled by selectively proportioning the air between the first and second portion so as to introduce into the first zone a quantity of air less than the stoichiometric amount required for the fuel introduced thereto and so as to introduce into the second zone a quantity of air sufficient to substantially complete combustion of the fuel within the furnace.
摘要翻译：燃料和燃烧空气的第一部分被引入远离炉的气体出口（14）的第一区（30）中的化石燃料燃烧蒸汽发生器的炉（10）中。称为过火空气的燃烧空气的第二部分在与炉的第一区和气体出口之间的第一区（30）间隔开的第二区（60）中被引入炉中。通过过热器表面（24）输送的过热蒸汽的出口温度通过选择性地将引入炉中的过热空气引导到炉的气体出口来调节，以增加过热蒸汽出口温度，并选择性地将引入的过热空气引导到炉子远离炉子的气体出口，以减少蒸汽过热出口温度。此外，通过选择性地将第一和第二部分之间的空气配比来控制在燃烧器中燃烧燃烧期间形成氮氧化物，以便将第一和第二部分之间的空气量排入少于燃料所需的化学计量量引入并且向第二区域引入足以基本上完全燃烧炉内的燃料的空气量。
