Power plant condensate energy storage system

What is a condensate system in a power plant?

Swapan Basu, Ajay Kumar Debnath, inPower Plant Instrumentation and Control Handbook (Second Edition), 2019 After work is done at the turbine, the exhausted steam is cooled in the condenser to form a condensate system.

What is steam condensate system?

This master’s thesis focuses on the design of steam condensate system of steam power plants. Condensate is generated when fractions of extracted steam from the turbine transfer heat to feedwater in the feedwater heaters. Also small amounts of condensate form in steam pipelines due to radiation heat loss.

Can compressed air storage integrate into regenerative subsystem of coal-fired power plant?

A novel compressed air storage system that integrates into the regenerative subsystem of coal-fired power plant is proposed. The mathematical model is established, and the possible coupling schemes are discussed. Furthermore, analyses of thermodynamics, purchased-equipment costs and key parameters are carried out.

How a thermal energy storage system is integrated into a power plant?

The thermal energy storage system is integrated into the power plant in order to reduce the minimal load operation of the auxiliary boilers. The fully charged storage can assume standby operation, which was to-date the operation in the minimal load of an auxiliary boiler.

Can latent heat storage be integrated into a cogeneration power plant?

Here we integrate a megawatt-scale latent heat storage into a cogeneration power plant in Wellesweiler-Neunkirchen, Saarland, Germany. The storage produced superheated steam for at least 15 min at more than 300 °C at a mass flow rate of 8 tonnes per hour. This provided thermal power at 5.46 MW and results in 1.9 MWh thermal capacity.

How does a condensate system work?

The fractions of extracted steam after transferring heat energy (enthalpy of evaporation) to the feedwater in FWHs changes into condensate. The condensate formed is then cascaded backward to lower pressure FWHs in the network or pumped forward to higher pressure FWHs or deaerator, depending on the design of condensate system.
