Abstract: We show that, in spite of the low heat of combustion of oil shales, use of them on the basis of a new thermal-processing technology that produces high-calorie products (shale tar and fuel gas) makes this type of fuel competitive for thermal power plants (TPPs) in comparison with high-calorie coals. When a certain amount of shale tar and all of the fuel gas are used in a combined cycle of a TPP, the specific fuel consumption for power generation is reduced by 25%. Line diagrams are given for high-efficiency TPPs based on the new technology for the thermal processing of shales.

Keywords: oil shale; OS processing; thermal power plant (TPP); solid heat carrier unit (SHCU); OS of Leningrad deposit; OS of Israel deposit; decomposition carbonates; thermal efficiency; low calorie fuel; combined cycle unit; UTT.
