Solar Thermal Power Plants with concentrating technologies are important for providing a major share of the clean and renewable energy needed in the future. Dish based system is a promising option for power generation since it has high concentration ratio and it does not require a large space. This paper presents a proposed solar dish based combined cycle: air based Brayton cycle as the topping...

In this paper, an innovative power plant, constituted by a gas turbine in combined-cycle fuelled by a synthesis gas (or syngas), produced in a local biomass gasifier, is analyzed. The plant is integrated with an external combustion system, fed by cellulosic biomass, connected to a heat exchanger able to increase the air temperature, as in a regenerative cycle. The combustion products pass throu...

The improvement of gas turbines flexibility has been driven by more use renewable sources power due to environmental concerns. There are different approaches improving turbine flexibility, and they have performance implications for the bottoming cycle in combined (CCGT) operation. CCGT configuration is favourable generating output, higher thermal efficiency that key economic viability electric ...

Biomass based Indirectly Heated combined heat and power plant can be an excellent option for community scale power generation. The thermal performance of such a plant employing air-turbo generator block and bottoming steam turbine block has been analyzed over a range of pressure ratio (2-16) and for different turbine inlet air temperatures (1073, 1273 and 1373K). The conventional GT combustion ...
