Coal Quality & Handling for Power Plant
Background & About the Course
Coal is primarily used in the Steam Power Plant (PLTU) industry, as well as in the Cement, Textile, Metal, and other industries. Each coal consumer has specific requirements tailored to their combustion needs. These requirements include size, moisture content, ash content, calorific value, Hardgrove Grindability Index, sulfur content, ash fusion temperature, and more.
This training is essential to ensure the proper selection and utilization of coal for improved efficiency in power generation.
Course Objectives
- Ensure the effective selection and utilization of coal to enhance power plant efficiency.
Who Should Attend
This training is recommended for:
- Coal-producing companies, both large and small
- Coal traders
- Users of coal, such as Steam Power Plants (PLTU), Cement, Textile, and Metal industries
- Participants from departments such as Planning, Crushing Plant, Coal Preparation Plant, Coal Trading, Coal Handling, Marketing, and Quality Control.

About the Course Leader
Slamet Suprapto, M.Sc. is a retired researcher from the Mineral and Coal Technology Research and Development Center (PPPTMB – tekMIRA), specializing in coal characterization and gasification. His extensive knowledge in coal characterization has led to the establishment of standards still used in tekMIRA’s coal laboratory. His research in coal gasification culminated in the development of a Diesel Power Plant (PLTD) using a dual-fuel system, combining diesel oil and gas produced from coal gas, with a composition of 60% coal gas and 40% diesel oil.
Currently, he is an adjunct instructor at the Mineral and Coal Technology Training Center and teaches courses on coal characterization and utilization technology, while also serving as a private consultant in coal technology.
