M40 backpressure turbine is single backpressure turbine.Its rotor uses a velocity-compounded stage impeller.Nozzle pitch diameter is 1040mm.Its speed regulating system can use KOEI electronic speed governing,and also can use woodward TG17 or TG13 mechanical governor,not forced lubrication. Its speed of main shaft is 1500-4500r/min,and it can achieve gear shaft output to installation of gearbox according to user requirements.The main feature of moders is the use of low –temperature,low-pressure steam as steam source dragging revolving mechanical doing work to realize the energy stave using for energy conservation and economize on raw materials.
