Siemens Power Generation, Inc. - Orlando FL

International Classification:

F25B 27/00

US Classification:

622383, 62304, 60 395, 261 88

Abstract:

The exhaust gas of a turbine engine can include water vapor. Aspects of the invention relate to various systems for recovering water from the exhaust gas of a gas turbine engine. In one system, a portion of the exhaust gas can be routed to an absorption chiller. In another system, a portion of the exhaust gas can be routed to a direct contact heat exchanger. In a third system, a portion of the exhaust gas can be routed to a fin-fan cooler. In each of these systems, the portion of gas can be cooled below its dew point temperature to release a portion of its humidity as liquid water. Aspects of the invention can be used with the turbine exhaust of simple and combined cycle power plants. A water recovery system according to aspects of the invention can minimize or eliminate a power plant's dependence on local water sources.

Assignee:

Siemens Energy, Inc. - Orlando FL

International Classification:

F02C 6/04

US Classification:

60785, 60782, 60795

Abstract:

Aspects of the invention relate to a system and method for operating a turbine engine assembly. The turbine engine assembly has a turbine engine having a compressor section, a combustor section and a turbine section. The combustor section has a lower T_PZ limit and the turbine engine has a design load. The assembly further includes at least one air bleed line from the compressor and at least one valve for controlling air flow through the bleed line. Control structure is provided for opening the valve to allow bleed air to flow through the bleed line when an operating load is less than the design load. The flow rate through the bleed line is increased as the operating load is decreased, reducing the power delivered by the turbine assembly while maintaining the T_PZ above a lower T_PZ limit. A method for operating a turbine engine assembly is also disclosed.

Abstract:

A cooling system for turbine engines for controlling cooling of rotor cooling air and heating of fuel gas is disclosed. The cooling system may be formed from a housing formed from a main plenum, a rotor air cooler positioned at least partially in the main plenum and a fuel gas heater positioned at least partially in the main plenum downstream from rotor air cooler. The cooling system may include a by-pass plenum for returning used cooling air back to a region upstream of the rotor air cooler. An exhaust fluid control device may control fluid flow out of the first exhaust opening at the second end of the main plenum, and a by-pass fluid control device may control fluid flow into the by-pass inlet opening of the by-pass plenum. The control devices and a fan may control circulation of cooling fluids through the main plenum.

International Classification:

F02C 618
F02C 7224

US Classification:

60 39182

Abstract:

An improved system for recovering waste heat from a combustion turbine in a combined cycle power plant of the type that includes at least one combustion turbine and at least one steam turbine includes a first heat recovery system for heating condensate in the steam turbine cycle with heat from the hot exhaust gases from the combustion-type turbine, and a second heat recovery system for heating the fuel that is used in the combustion turbine with heat from the exhaust gases. The second system permits recovery of heat energy that is not recovered by the first system, thereby improving plant efficiency.

Gerald A. Myers - Longwood FL

Assignee:

Westinghouse Electric Corp. - Pittsburgh PA

International Classification:

F01K 700

US Classification:

60 39182

Abstract:

A deaerating subsystem in a combined cycle power plant includes a deaerator and a storage tank coupled to the deaerator, the deaerating subsystem being adapted for isolation of the deaerator when it is defective even while the overall combined cycle power plant is operating. Blind flanges are provided in a downcomer and in vapor risers between the deaerator and the storage tank for such isolation. Also provided is a condensate bypass for preventing the reception of the condensate by the deaerator, and for enabling the storage tank to receive the condensate directly. Thermal energy is input into the storage tank such that controlled amounts of heated condensate from the steam generator, and controlled amounts of dry steam can be input to the storage tank while the deaerator is isolated for repairs.

International Classification:

F02C 618
F02C 7224

US Classification:

60 3902

Abstract:

The efficiency of a combined cycle power plant is improved by preheating fuel supplied to a combustion turbine. The flow rate of feed water through an economizer section of a heat recovery steam generator is increased, and the excess flow, over that required to sustain saturated steam production in an evaporator section, is flowed through a heat exchanger to preheat the fuel.

International Classification:

F01K 1302

US Classification:

60660

Abstract:

In a combined steam generator-turbine system, a drain type is provided in front of the stop valve to drain the first steam supply with the stop valve closed until the temperature of the valve and/or the temperature of the steam exceeds the temperature of saturation by a predetermined amount, and logic circuitry is provided to generate permissive signals which combine to allow successive admission of steam to the gland seal and to the steam turbine.
