M20

M20 backpressure turbine is single stage backpressure.Its rotor uses a velocity-compounded stage impeller..Nozzle pitch diameter is 624mm.Its speed regulating system can use KOEI electronic speed governing,and also can use woodward TG17 or TG13 mechanical governor,non-forced lubrication.Its speed of main shaft is 1500~4500r/min and it can achieve gear shaft output to installation of gearbox according to customer requirements.The main features of models is the of low-temperature,low-pressure,low-differential pressure steam ad steam source dragging turbo-dynamo doing work to realize the energy conservation.When ordering,please send us the following informations.1.What kind of driven machinery to be used.2.Number of units required.3.Required output.4.Required speed and direction of driven machinery.5.Steam parameters:(a)Inlet pressure(b)Inlet temperature or superheat degree(c)Exhaust pressure6.Destired steam consumption7.Required speed regulating range and foverning method.8.Operation mode:Continuous,intermittent or spare.9.Arrangement mode:Single-deck or double-deck,and requirements concerning the orientation of steam inlet and exhaust piping.10.Ambient condition:Indoor or outdoor,conditions of dust and hazardous gas in air.atmospheric pressure and temperature.11.Colling water conditions:Temperature,water quality.12.Date of delivery and destination.Technical specifications of the prdduct:Trpereted power(KW)Speed (r/m)Inlet pressure MPaInlet remperature℃Exhaust pressure  MPaStearate Kg/KwHcodeB0.132-0.5/0.1513230000.52500.1526.8     M20B0.25-0.6/0.22503000.602500.229.26B0.35-0.98/0.1535030000.983000.1519.4B0.35-0.98/0.235030000.983000.220.2B0.35-0.98/0.335030000.983000.324.2B0.35-0.98/0.535030000.983000.539.6B0.45-0.98/0.1545030000.983000.1518.6B0.45-2.35/0.245030002.352250.218.7B0.55-0.98/0.1555030000.983000.1518.2B0.63-0.98/0.263030000.983000.218B0.75-1.27/0.275030001.273300.217.2Note:The pressure of feed and exhaust steam is absolute pressure.The weight of turbine’s main body is 2.9T.
