Abstract

The invention relates to a method of supplying coal and sulphur absorbent to a combustor (10) with combustion in a fluidized bed (16). The coal is crushed and sorted into a finer and a coarser fraction. The finer fraction is mixed with water, possibly with oil and/or emulsifier, into a paste. This is pumped into the bed (16) of the combustor (10) via a number of first nozzles (32). The coarser coal fraction is supplied to the combustor pneumatically in dry state, direct or via one or more lock hopper systems (60) and a number of other nozzles (36). The invention also relates to a power plant for application of the method.
