<P>PROBLEM TO BE SOLVED: To provide a gas engine system which can know ratio of soot or hydrocarbon in fuel gas of a gas engine on line to continue stable combustion. <P>SOLUTION: The gas engine system 10A includes: a fuel gas supply pipe 12 for supplying fuel gas 11 to the main combustion chamber 101 and sub-combustion chamber 119 of the gas engine; and a laser analysis device 13 for irradiating laser beam 14B onto the fuel gas 11 in the fuel gas supply pipe 12 to measure the gas composition and the soot concentration of the fuel gas 11. The system further includes: a first bypass pipe 33A branched from a branch part 31 of the fuel gas supply pipe 12 and having a first filter 32; and a control means 21 for controlling to introduce the fuel gas 11 into the first bypass pipe 33A when a soot amount is determined to exceed a threshold from a measurement result of the soot concentration by the laser analysis device 13. <P>COPYRIGHT: (C)2012,JPO&INPIT |
