The test state for admixing combustion of coal imported from Indonesia in boilers of four 350MW units at Huaneng Nantong Power Plant has been presented. In view of the features concerning Indonesia coal

such as high volatile content

high calorific value

and low ash content etc.

some practical and feasible measures for admixing combustion have been put forward. From successful trial combustion

experiences of burning coal sort with high volatile content have been accumulated

expanding the applicable range of fuel coal for boilers

reducing the operation cost of units

obtaining comparatively good economic benefits.
