Evaluating fuel consumption factor for energy conservation and carbon neutral on an industrial thermal power unit

摘要

Energy conservation was crucial for operating one industrial power device unit, because the better energy management was beneficial for decreasing the cost during the operation. On the other hand, in a carbon-neutral context, decreasing the Greenhouse gas (GHG) emission was as important as the energy conservation. In this paper, the direct method of the evaluation on the fuel consumption for the energy management was investigated. The fuel consumption factor for the energy conservation was studied in terms of ten different types of the single fuel consumption factor, the average value of the single fuel consumption factor, and the total fuel consumption factor. The result showed that the maximum of the fuel consumption factor was from the backpressure in the turbine part. The fuel consumption factor decreased from 12.65 g/kWh to 9.23 g/kWh after the optimization during the operation. The effect for the energy conservation could reach over 80%, and the cost saving for the optimization could be over 4.65 million US dollars for one year on one power station in China. the goal on the analysis of the fuel consumption factor was controlling the use of the coal, and thus also controlling the CO2 emission.
