Black starting

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.

Thomas Thomson received his M.D. degree at Edinburgh in 1799, where he was inspired by Joseph Black. Starting in 1800 he lectured on chemistry at Edinburgh and published the first edition of his comprehensive A System of Chemistry in 1802. Thomson visited Dalton in 1804 and enthusiastically adopted his atomic theory. Interestingly, the first published statement of Dalton s theory appeared In the third edition (1807) of Thomson s five-volume chemical treatise. ... 

Some of the vital and essential loads are required when the plant is to be started up, and there is no normal power available. In this situation the starting up of the plant is called black starting . The emergency generator must be started from a source of power, which is usually a high capacity storage battery and a DC starter motor, or a fully charged air receiver and a pnemnatic starter motor.
