PROBLEM TO BE SOLVED: To provide a syngas supply system capable of stably supplying syngas produced from coal as fuel for power generation or particularly for a petrochemical plant which requires long-term stable fuel supply.SOLUTION: A syngas supply system comprises: first header piping 12a and second header piping 12b which are connected to a plurality of gasification furnaces and at least one gas user; connection piping 22 which connects the first header piping 12a and the second header piping 12b; a connection valve 24 installed on the connection piping; and pressure detection means 26 A and 26B which are installed on both sides of the connection valve on the connection piping. When values detected by the pressure detection means 26A and 26B are lower than a predetermined threshold, the syngas supply system performs stably supply of syngas to the gas user 20A in a manner that sends the syngas from one header piping to the other header piping by opening the connection valve 24. |
