1. A combustion-gas supply system, comprising:
a main pipeline, comprising a first sub-pipeline and a second sub-pipeline connected with the first sub-pipeline; and
a multi-functional pipeline,
wherein:
the first sub-pipeline comprises:
a first gas intake pipe, a first gas supply valve and a first gas outlet pipe arranged in sequence, the first gas intake pipe being configured to input the combustion-gas;
a combustion-gas pressure regulating valve located between the first gas supply valve and the first gas outlet pipe; and
a bypass one-way valve, an input end of the bypass one-way valve being in communication with the first gas outlet pipe, an output end of the bypass one-way valve being located between the combustion-gas pressure regulating valve and the first gas supply valve, and the bypass one-way valve permitting flow therethrough in a direction from the input end to the output end, and disallowing flow therethrough in a direction from the output end to the input end;
the second sub-pipeline comprises a combustion-gas supply valve and a gas supply pipe, the first gas outlet pipe being connected with the combustion-gas supply valve and the gas supply pipe being configured to be connected with a turbine engine;
the multi-functional pipeline comprises a second gas intake pipe, a second gas supply valve and a second gas outlet pipe arranged in sequence, the second gas outlet pipe being connected to the first gas outlet pipe; and
the combustion gas comprises a gaseous fuel.
