① Suitable for dry and arid areas. Good for water conservation.
② The last stage blade is designed for this type of steam turbine specially; therefore the steam turbine is of high-efficiency, safe, reliable and suitable for the working condition with high exhaust pressure and wide range changing.
③ Both the adoption of full three-dimensional flow for low pressure stage and the through-flow with a smooth access ramp improves efficiency.
④ The rear bearing is floor type to improve shafting stability.
⑤ The low-pressure casing adopts linked tube to jet water, which has solved the problem of LP casing overheating when back pressure is very high in summer.
⑥ Both the second stage and the third stage from the last adopt the honeycomb type gland, which plays the role of dehumidification and improving efficiency.
