The performance of a steam-gas power unit of a velox-type cycle

Smołka K., Dykas S.

Journal of Power Technologies

2017

Vol. 97, nr 5

343--348

For many years, the Institute of Power Engineering and Turbomachinery of the Silesian University of Technology has been using a Velox-type small-capacity gas-steam power unit for teaching and research purposes. The Velox-type gas-steam cycle is characterized by a much higher ratio of power obtained from the steam turbine and the gas turbine, respectively, compared to classical gas-steam cycles which are now in use worldwide. This paper presents a thermodynamic analysis of the Veloxtype gas-steam cycle as a small capacity combined heat and power plant (CHP). The systems are modelled in the EBSILO Nr Professional. The advantages and drawbacks of the Velox-type cycle compared to the classical one are presented.

Matching of a gas turbine and an upgraded supercritical steam turbine in off-design operation

Kosman W.

Journal of Power Technologies

2015

Vol. 95, nr 1

90--96

The results of the research presented in this paper refer to an upgrade of a power generating unit with a supercritical steam turbine of a moderate live steam temperature. The upgrade project involves replacing the high pressure part with a turbine driven by a high live steam temperature and adding a gas turbine. The aim of the upgrade is to increase power generation efficiency. The specific problem analyzed in the paper corresponds to the matching between the gas and steam turbine especially in off-design conditions. The analysis is based on the numerical modeling of the thermodynamic cycles. Various conditions of the operation were simulated. The results obtained enable efficiency to be assessed in the analyzed variants.
