Fuel gas mixing system for power station

The utility model relates to a fuel gas mixing system, in particular to a fuel gas mixing system for a power station. Comprising a natural gas filtering, heating and metering flow control branch and a control system, and further comprises a synthesis gas filtering and metering flow control branch and a mixed gas mixing pressure stabilizing circuit. And the natural gas filtering, heating and metering flow control branch and the synthesis gas filtering and metering flow control branch are connected in parallel and then are connected with the mixed gas mixing pressure stabilizing circuit and the control system through a gas conveying pipeline. The parameter range in each branch module is set according to the gas transmission requirements of gas turbines of different models so as to meet the power generation requirements of the gas turbines of different models. The low-calorific-value and low-cost synthesis gas of a petrochemical refining plant is utilized for combustion for power generation, the use cost of natu
