Use of Unconventional Fuels in Gas Turbines

Abstract

In several industrial processes, various hydrocarbons, such as low BTU blast furnace gas, syngas, Naphtha, heavy oil and condensate, are available as by-products or residues. Burning such unconventional fuels for combined cycle power generation can be attractive in certain countries due to their low prices or availability compared to natural gas or distillate. In this paper, design and operating experience of combined cycle power plants burning such unconventional fuels, e.g. Bao Shan in China burning LBTU gas, GVK in India burning Naphtha and Api in Italy burning medium Btu gas from heavy oil (refinery bottom) gasification etc. are discussed. The high degree of manufacturers’ ability to develop such projects and design the required equipment — burners/combustors, CC power train and control systems — is illustrated. In addition, the development of Naphtha and condensate burner for GT13E2 is described in short.
