摘要： In a combined cycle power plant operable on either gas or liquid fuels maximum design efficiency is achieved at the lowest HRSG stack temperatures. This can be optimized for operation on natural gas but for liquid fuel operation consideration must be given to sulfur cold end corrosion. A feedwater recirculation loop is shown which allows for selectively heating feedwater during liquid fuel operation and for non-heating during gas operation. Economizer recirculation is also introduced to prevent economizer steaming.

摘要： In a steam generating system, steam condensate extracted from steam used to reheat boiler water in heaters (H1, . . . , H4) is revaporized in the recuperators-vaporizers (RV1, . . . , RV3) by heat exchange contact with the flue gas from boiler (B). The steam thus formed is recycled to contribute to the reheating of the water fed to the boiler.

摘要： The present invention concerns an integration construction between a steam boiler provided with a combustion chamber and a steam turbine. The steam is conducted from the steam boiler (10) along a connector to the steam turbine (11) for rotating an electric generator (K) producing electricity. The supply water circulated via the steam boiler (10) is vaporized in a vaporizer (190) located in the steam boiler (10) and superheated in a superheater (120). The supply water is conducted into the boiler through an economizer (20) acting as a heat exchanger, where heat is transferred from the flue gases of the boiler into the supply water. The economizer (20) is provided with at least two sections, comprising at least one first economizer section (20a1) and at least one second economizer section (20a2). The supply water is conducted from the first economizer section (20a1) to a supply water preheater formed from a heat exchanger (14), where thermal energy is transferred from bled steams of the steam turbine either directly or via a medium, advantageously water, into the supply water. The supply water preheated with bled steams of the steam turbine is conducted in the steam boiler (10) to the second economizer section (20a2) and further to the vaporizer (190) and the superheater (120) and therethrough, in the form of steam, to the steam turbine. In the integration construction, the temperature of the supply water is raised continuously as the supply water is flowing in the first economizer section (20a1) and from the first economizer section (20a1) to the supply water preheater (14) and threthrough, to the second economizer section (20a2). The connector (13a1.1) leading to the supply water preheater (14) comprises a valve (21) for controlling the bled-steam.

摘要： Methods and systems generate steam and carbon dioxide mixtures suitable for injection to assist in recovering hydrocarbons from oil sands based on concentration of the carbon dioxide in the mixtures as influenced by temperature of water introduced into a direct steam generator. Increasing temperature of the water to above 200° C. before introduction into the direct steam generator may utilize heat from an electrical power generation unit. Enthalpy of this preheated water impacts amount of fuel needed to burn in the direct steam generator and hence the concentration of the carbon dioxide, which may be below 11% by mass percent of the steam.

摘要： The invention concerns a procedure for improving the efficiency of a steam power plant process wherein damp fuel is used, which is dried by conducting at least part of the flue gas flow to a fuel drying process. In addition to the feed water the combustion air is preheated in steam power plants with tapped steams from the turbine, in counter-pressure power plants with tapped steams and/or counter-pressure steams, and in remote heating power plants with tapped steams and/or remote heating water. As taught by the invention, the temperature of the flue gas going to the damp fuel dryer installation (10), or the cooling of the flue gas flow by-passing it, is controlled by taking thermal energy from the flue gas and transferring it to the combustion air and/or the feed water, their quantity and/or temperature being controlled in accordance with the cooling requirements of the flue gases determined by the drying requirements of the damp fuel.
