Abstract The invention discloses a gas supply system for feeding gas mixture with measuring balance set used in condition of high temperature and corrosion. The system is composed of measuring set, heating set, mixing gas set and handling tail gas set. Said mixing gas set includes multi gas cylinders, mixing gas cylinder, electric flow meter and vacuum pump. One of said cylinders is connected to the heat balance in the measuring set finally, by through vacuum hose via vacuum valve, floater flow meter connected to the vacuum valve in parallel. The rest of cylinders through the vacuum valve, the electric flow meter, then are connected to the mixing gas cylinder. One part of the output of the mixing gas cylinder via the vacuum valve is connected to reactor in heating furnace, the outer part of the mixing gas cylinder via the vacuum valve is connected to the vacuum pump and the heat balance. The set handling tail gas without pollution and capable of simulating complex atmosphere is installed on the output end of the reactor.
