Coal consumption

• Loss in handling:– Droppings in internal transport:

• Equipment:– Open conveyor;– Dropping from trucks;

• Incompetenct loading/undloading worker;

Coal consumption

• Low Burning efficiency:– High moisture content of coal:

• Unsheltered storage area;

– Boiler:• Old Technology;• Inappropriate maintenance.

– Method: • Inappropriate operation standard;

– Operator:• Incompetent;

Coal consumption

• Loss of steam:– Bad insulation:

• Less effective insulation material;• Lack of inspection and maintenance.

– Loss steam:• Leakage of pipe/connection;

– Non-reuse of steam.

Coal consumption: Objectives

• Achieving 10% reduction of 2005’s coal consumption per unit of crude oil by the end of 2006.
