TL;DR: A comprehensive three-dimensional computational fluid dynamics (CFD) model is developed, which allows us to describe complex phenomena that occur in the combustion chamber of the CFB boiler burning coal and syngas produced from coal sludge.

TL;DR: The results indicate that the syngas supply leads to an increase in local temperature and carbon dioxide concentrations, and the proposed concept is not advisable as it may lead to frequent emergency stops of the CFB boiler.

TL;DR: In this paper, the possibilities of integrating the adsorption aggregate with a combined cycle gas turbine and its impact on the operation of all devices were discussed, and the obtained results confirm that the adorption aggregation, using a low grade of thermal energy, does not affect the operation and allows the production of electricity at a constant level, while the calculated chemical fuel energy utilisation factor was 85.7% in cogeneration and 75.6% in trigeneration.

TL;DR: In this paper, a 10 kW polymer exchange membrane fuel cell (PEMFC) stack consisting of two 5 kW modules, connected in series with a multi-function controller unit was constructed and tested.

TL;DR: In this article, the authors present a CFD study on flow characteristics in the centrifugal fan in nominal and off-design conditions, using ANSYS CFX package to determine the performance curve of the fan.
