Feasibility study on effective use of energy in the cement manufacturing process

Abstract

An investigational study was conducted of a project for energy conservation and greenhouse effect gas reduction by introducing the steam injection gas turbine generator to production facilities of the Siam Cement Industry Corporation (SCI) in Thailand. In the project, studies were made on the following: no purchases of electric power by introduction of the steam injection gas turbine generator; additional heating by gas turbine exhaust gas by introduction of the kiln combustion air heater; remodeling of the preheater of raw materials, and the partial calcination before kiln sintering by introduction of the calcination furnace. As a result of the study, the energy conservation amount was 1,200 toe/y, and the greenhouse effect gas reduction amount was approximately 8,000 t-CO2/y, which led to the reserve power for increased production of clinker by about 18%. The size of investment was 314.5 million Baht in total. As to the evaluation of economical efficiency of the investment, the actual period of ROI was a little less than 5 years, and the internal earning rate was 17.7%, which substantially met with SCI's standards for equipment investment. However, there are problems on the gas supply infrastructure, recovery of the white cement demand, etc. (NEDO)
