Abstract

Coal is a cheap fuel, so it is widely used by steam power plants (PLTU). With many PLTUs using coal, the demand for coal  increases and the quality of the coal is decreasing and the price continues to rise. With this problem, it is necessary to improve  coal quality, one of which is by upgrading using a gas exhaust boiler. With using rotary dryer, the coal will be upgraded from low calorie to high calorie by reducing the moisture content, which will then be applied to the tempo cycle software 5.1. After application at cycle tempo 5.1, the best efficiency increase for PLTU can be increased efficiency and decrease coal rate, which is best obtained in the third experiment which achieved 37,041% efficiency with a coal rate of 17,567 kg / s.

Abstract Steam Power Plant (PLTU) is a source of electricity that is widely used in various countries because it has several advantages including technology that has been mature, cheap fuel, and long lifetime. The working principle of the PLTU is to rely on the kinetic energy of steam to produce electrical energy that uses a generator to rotate the turbine. This power plant uses coal or oil as fuel to heat water. The use of coal as fuel is still a mainstay in Indonesia because of the available sources and low prices. However, the use of coal can cause CO2 gas pollution which is harmful to the environment and health. For this reason, the design and characteristics of a good steam turbine are needed in order to produce an effective and optimal combustion with low CO2 emissions. In this review paper, various research results are presented showing that steam turbine designs are innovative, efficient, and environmentally friendly in generating electricity power.
