PROSES MIXING BATUBARA GUNA MEMENUHI PARAMETER KUALITAS BATUBARA YANG DIBUTUHKAN DI PLTU NAGAN RAYA 2 X 110 MW

Abstract

Nagan Raya Regency is one of the new regencies in Aceh Province. Geographically, Nagan Raya Regency. Nagan Raya PLTU operates a power plant with a capacity of 2 x 110 MW to support the electricity needs of the community. Coal production and consumption in Indonesia will be increased, especially as fuel. Nagan Raya PLTU is a steam power plant company. This study aims to determine the value of coal parameters before and after mixing. To conduct laboratory testing, the ASTM D2013/D2013M preparation procedure - 21 standard practice for preparing coal samples for analysis was carried out, previously and then the proximate, ultimate, and calorie testing procedures were carried out in the laboratory. The mixing results using the moisture value statistical method were 17.18% while the boiler specifications were 35% from the moisture value statistical results below the boiler standard that met the boiler standard, it was concluded that the low moisture value had a good impact on the boiler because if the moisture value was low, the heat generated would increase. And the mixing results using the statistical method the ash value is 6.36% while the boiler specification the ash value is 6% from the statistical results the ash value is higher than the boiler specification, it can be concluded that the higher the ash content, the higher the boiler efficiency value. This ash is very susceptible to air pollution levels and causes acid rain which causes rust on equipment.
