摘要： An apparatus and method for recovery of waste heat in a boiler system, wherein heat from the low pressure steam in the feed water tank, which otherwise would be lost through dissipation, is used for other applications. Particularly, the waste heat energy recovered in the form of low pressure steam can be used to heat make-up water for the boiler system.

摘要： A steam power plant includes a first steam power plant, a second steam power plant, and an inter-unit. The first steam power plant includes a boiler, a high-pressure turbine, a first reheat line, a first feed water heater, and a high-pressure extraction steam line. The second steam power plant includes a boiler, a high-pressure turbine, a first reheat line, a first feed water heater, and a high-pressure extraction steam line. The inter-unit connected extraction steam line connects the high-pressure extraction steam line of the first steam power plant with the high-pressure extraction steam line of the second steam power plant.

摘要： An injection feedwater heater for a steam power generating system includes at least one main heater body and at least one injection nozzle. The main heater body has at least one heat exchange compartment, at least one water inlet, at least one steam inlet, and at least one water outlet formed on the main heater body. The injection nozzle is provided in the main heater body at a position adjacent to the water inlet, wherein a predetermined amount of condensate water is arranged to be pumped into the main heater body through the water inlet. The condensate water passing through the water inlet is arranged to be injected into the heat exchange compartment through the injection nozzle for creating a negative pressure in the heat exchange compartment. The negative pressure drawing a predetermined amount of steam to enter the heat exchange compartment for mixing with the condensate water.

摘要： A steam turbine plant includes a high-medium pressure turbine having a high-pressure turbine section provided at one end portion in an axial direction and a medium-pressure turbine section provided at the other end portion; a low-pressure turbine disposed coaxially with the high-medium pressure turbine; a condenser configured to cool steam used in the low-pressure turbine to condense the steam into condensate; and a feed-water heater configured to heat the condensate with steam discharged from the high-pressure turbine section. The plant also includes a low-pressure moisture separating and heating device configured to remove moisture of steam discharged from the medium-pressure turbine section, and to heat the steam with a part of steam to be sent to an inlet portion of the high-pressure turbine section and a part of steam to be sent to an inlet portion of the medium-pressure turbine section from an outlet portion of the high-pressure turbine section.

摘要： The once-through boiler includes a water supply and at least an economizer, an evaporator superheater. No valves are provided between the economizer, the evaporator and the superheater. The high-pressure turbine includes a control valve. The method for low load operation of a power plant with a once-through boiler and a high pressure turbine includes providing a parameter indicative of the stable operation of the once-through boiler in once-through operation, and on the basis of this parameter adjusting the control valve in order to regulate the pressure within the economizer and evaporator and/or adjusting the temperature of the water supplied to the economizer.

摘要： Disclosed is a Once-Through Steam Generator (OTSG) coil (52) and method, comprising a plurality of vertically arranged serpentine conduits (90) in a horizontal heat recovery steam generator (HRSG) that replaces a traditional natural circulation HP evaporator for producing super-critical steam. The OTSG comprises a lower equalization header system (130) that promotes system stability in multiple operating conditions. The equalization header allows a partial flow of fluid from the lower serpentine curved flow path (120) through an equalization conduit (125) into the equalization header (130) Disclosed also are: a flow restriction device in serpentine conduits; drainage structure from serpentine conduits through the equalization header, a drainage expansion section to accommodate stresses, and drainage bypass connections; and flow through serpentine conduits in upstream and downstream directions, mixed flow directions and longitudinally staggered directions.

摘要： A preheating system for preheating fluid medium to be fed into the HRSG is disclosed. The system includes a feed line and a recirculation line. The feed line is adapted to feed the fluid medium to a Low Pressure Economizer (LPE) of the HRSG. The feed line is adapted to be adjoined to an inlet of the LPE, and an outlet of the LPE enables therefrom the flow of the fluid medium in further portion of the HRSG. The recirculation line is adapted to be connected between the outlet and the inlet of the LPE, in parallel to LPE to recirculate the fluid medium to the LPE. A particular method of preheating using such a system is equally disclosed.

摘要： A method for improving pulp mill steam cycle efficiency includes the steps of providing at least one deaerator tank having a first pressure, and lowering the pressure of said deaerator tank to a second pressure. Feedwater is supplied to a pre-economizer, where it is heated. The water is then delivered to at least one feedwater heater, where it is heated. The water is then delivered to an economizer. By this method boiler steam rate is increased while boiler efficiency is maintained and turbine extraction for deaerator and feedwater heating is minimized.
