Indouesian coal is an important complement for fuel coal used for power generation in eastern coastal region of our country

but most of said coal only can be utilized for bituminous coal fired boilers after mixing and blending. Results of study in laboratory for burning behaviors of a classical indonesian single coal sort and its blended coal

as well as test situation for utilizing said coal on 300 MW unit

have been presented. Results of analysis by using sedimentation stove and thermal balance show that the indonesian single coal has many features

such as ultrahigh volatile content and water content

low ash content

low ash fusing point

and low calorific value

boasting behaviors as extremely easy to fire

extremely easy to burnout

and seriously slagging. After coal blending

the ignition and slagging behaviors of said coal have been obviously improved

temperature field in the furnace and slagging tendency being also obviously improved

but having certain influence upon the drying capacity of coal pulverizer.
