We have TurboCare gas turbine. Since 1 month ago it is failing to start due to an unknown reason.
The starting system is diesel engine connecting with turqe converter type (VOITH Torque Converter EL9 YGTM 4.0-86).
The tubine starts to purge then ignition but when the speed become 1500RPM it is stopped by thermo regulation (temperature increase inside turbine).
We checked pilot and main fuel gas but all were ok.
I think the problem in the turqe converter but (turqe converter not accelerating the turbine to self sustained speed. Maybe variable guide vane not opening. Actualy I dont know if this guide vane will change opening during startup or not, and if yes, how this control will work.
Please help me to solve this problem.
