Black start capability

Gas versus steam turbines can involve a major side study. The result can be different for the process and utility sides of the plant as shown in Reference 13. For the gas turbine case, simple cycle versus waste heat boilers can be studied. Usually, waste heat boilers will win out unless the plant is in a cheap gas country. If gas turbines are selected for power generation, black start capability is usually a good investment. 

One of the most dangerous alien species of microfauna is the El-Tor strain, which causes epidemic outbursts of cholera these strains were registered in Kerch and Odessa coastal waters in 1970. In contrast to classical cholera, the El-Tor strain is capable of long-term (over a few months) existence and, most likely, is able to reproduce in brackish-water basins [10]. The way of its penetration to the region is still not clear meanwhile, starting from the moment of its appearance, has been often recorded in the near-shore waters off selected cities on the coast of the Black Sea and the Sea of Azov [11]. The social and economic losses caused by the El-Tor occurrence on the beaches are obvious, though no estimates have yet been made.
