reduction of ash deposition during upgraded brown coal (UBC) combustion and to understand the reduction mechanisms of ash deposition. The melting temperature of the UBC ash is 1494 K, which is relatively lower than that of bituminous coal ash. Before the actual ash deposition

2. Upgraded Brown Coal || KOBE STEEL, LTD.

By removing the moisture, Kobe Steels UBC Process raises the heat value, thereby converting brown coal into a high-grade energy resource. When UBC is used in thermal power generation, ash content and sulfur oxide emissions can be reduced even more than with bituminous coal, and CO 2 emissions can be more easily curbed than with brown coal.

ANALYSIS OF UBC UTILIZATION IN THE EXISTING COAL POWER ...

With the advanced technologies, such as Upgraded Brown Coal (UBC) process, LRC can be used optimally, particularly for the power plant. Suralaya Generation Business Unit (SGBU), which is the largest coal power plant in Indonesia, recently has to use lignite coal or low rank coal because the price of medium and high rank coal is too expensive.

4D2. Low-rank Coal Upgrading Technology (UBC Process)

Since the upgraded coal produced in the UBC process is still in a powder form, for transportation to non-local customers it is formed into briquettes. Using a double roll briquetter, the upgraded coal can easily be briquetted without the use of a binder. Photo 1 shows a picture of upgraded-coal briquettes. ˜ 2. Development target˜ 1) Upgrading cost˜

Change of combustion characteristics of Indonesian low ...

Upgraded brown coal (UBC) process has been developed to produce a dry upgraded coal which is comparable with a bituminous coal. Differential thermal and thermogravimetry analyses (DTA–TG) have been applied to study the combustion characteristics of some Indonesian raw and upgraded coals produced by the UBC process.
