The invention relates to a system capable of supplying coal gas to a power plant boiler. The system comprises a coal gas generating furnace and a power plant starting furnace, wherein the coal gas generating furnace is used for receiving oxygen, steam and coal powder, so that the oxygen, steam and coal power can react in a hearth of the coal gas generating furnace to generate coal gas; the power plant starting furnace comprises a combustion chamber, a first dust remover, a heat exchange channel, a heat exchanger, a gas-liquid separator and a steam header; the coal gas generating furnace, the combustion chamber, the first dust remover and the heat exchange channel are sequentially connected with the power plant boiler along the coal gas flowing direction, so that the coal gas can enter theheat exchange channel after passing through the combustion chamber where fire is stopped and can enter the power plant boiler after passing through the heat exchange channel, that is, the cooled coalgas without dust can be su
