In order to ensure the micro gas turbine can be reliably and safely operated on the plain and plateau area not less than 4500 m

this technical solution was designed by reducing flow number of single centrifugal fuel atomized nozzle

considering the parameter matching of oil supply control system. When the ignition and fuel supply quantity at starting process was reduced

and the coupling of nozzle and oil control system was changed

the problem of starting over temperature on the plateau was solved. The test on plain and plateau showed that the success rate of ignition start-up was 100%

the highest exhaust temperature was 720℃ through plateau starting process

which was consistent with the state of the original design working environment on the plain

and the starting time was less than 40s. This can guarantee the safety of ignition and starting process and reliability on plain and plateau

helping to satisfy gas turbine property on the condition of plain and plateau.
