Combined fuel cell?gas turbine plant for highly efficient power generation from renewable energy sources
The impact of renewable energy sources on today's energy supply substantiates the importance of hydrogen as an energy carrier. Hydrogen can be directly produced from solar energy and is considered a promising technology for temporary storage of electrical energy from wind turbines and photovoltaic systems. The generation of electrical energy from stored hydrogen requires highly efficient systems ...

The 700?C steam turbine power plant ? status of development and outlook
This paper appraises the current development status of the 700?C steam power plant under consideration of process optimisation as well as design aspects of the steam turbine and steam generator. The results for a compact arrangement of the steam turbine and steam generator are also presented. Based on a cycle analysis, a net efficiency between 49.3% and 51.4% can be achieved with the 700?C steam ...

Quantifying Combined Heat and Power (CHP) activity
In CHP plants without heat rejection facilities power, output is complementary to the recovery of heat, and all activity is cogeneration. CHP plants with heat rejection facilities can operate a mix of cogeneration and condensing activities. Quantifying the energy flows of both activities properly requires knowledge of the design power-to-heat ratios of the CHP processes (steam and gas turbines, ...

A Structured Approach to Steam System Improvement through Utility System Design and Optimisation
Optimal operation of site utility systems is becoming an increasingly important part of any successful business strategy as environmental, legislative and commercial pressures grow. A reliable steam model allows a clear understanding of the system and of any operational constraints. It can also be used to determine the true cost of improvement projects, relating any changes in steam demand back ...
