System for Generating Hot Water and/or Steam with High-Temperature Storage for Use in a Gas Turbine Power Plant

Simple SummaryContent extracted from patent full text and abstract with AI.

The invention is a high-temperature storage system designed for producing hot water and/or steam, specifically for use in gas turbine power plants. It can be charged using both external (such as surplus electricity, solar heat, or industrial waste heat) and internal heat sources. The heated water or steam can then be injected into the gas turbine cycle at various points to enhance performance. The system features a flexible storage medium and design, enabling efficient conversion, storage, and on-demand delivery of heat at high pressures and temperatures.

Use CasesContent extracted from patent full text and abstract with AI.

• Improving efficiency and flexibility of gas turbine power plants by storing and providing high-temperature water or steam on demand.
• Integration of renewable energy sources (e.g., wind or solar) through thermal storage of surplus energy for later use in power generation.
• Utilizing waste heat from industrial processes for electricity and heat generation in combined heat and power plants.
• Supplying district heating systems with hot water from thermal storage.
• Fast power plant start-up and enhanced load-following capabilities during electricity demand peaks.

BenefitsContent extracted from patent full text and abstract with AI.

• Enhances efficiency and output of gas turbine power plants by utilizing stored thermal energy at high temperature and pressure.

Patent Abstract

The invention relates to a system for producing hot water and/or steam having a high-temperature reservoir for use in a gas turbine power station, wherein the energy for charging is provided from at least one external energy source and/or from an internal energy source of the gas turbine power station, and wherein the hot water and/or the steam (D) can be delivered in an open process for injection into a fluid stream between the compressor and the turbine and/or the turbine of the gas turbine power station, wherein at least one channel (4) leads through the high-temperature reservoir (2.2), and by heat transfer an increase in pressure and/or temperature of the water (W)/hot water (HW) can be achieved in such a way that hot water (W) and/or steam (D) comes out from the channel (4) at an outlet temperature (T2) > the inlet temperature (T1), wherein the high-temperature reservoir (2.2) has connections for direct and/or indirect charging which for direct charging are coupled to at least one external energy source and/or for indirect charging are coupled to an external energy source which supplies electrical energy.
