Dresser-Rand Manufactures Largest Single-Casing Steam Turbine Another milestone achievement has been reached by Dresser-Rand -- its Steam Turbine Strategic Business Unit (SBU) recently completed production and testing of the largest single-casing steam turbine ever produced by the company. The landmark unit is the result of nearly 16 months of engineering and production, according to Mike McGuinness, sales and marketing manager for Dresser-Rand's Steam Turbine SBU. “This is a 69 MW steam turbine measuring 24 feet in length. When coupled to the generator, the length of the unit measures more than 49 feet.” The unit is a double-controlled extraction/ condensing turbine that will be used to generate power by a major paper manufacturer in the southeastern United States. “This steam turbine is part of the client’s overall effort to reduce power generation costs at their facility,” McGuinness added. “Steam for the turbine will be generated by a boiler fired by tree bark and petroleum coke (which replaces an older, natural gas-fired boiler), making the system more economical as the price of natural gas rises.” By replacing the gas-fired boiler with the more flexible bark-and-coke-fired boiler, the client anticipates reducing overall purchased power by 90 percent, and reducing natural gas consumption for steam generation by 70 percent. Additionally, the two extraction steam pressure levels produced will be used in the papermaking processes. The success of the project is the result of teamwork and innovation, according to McGuinness. “Every team member contributed and worked efficiently to meet the requirements of the project, with these very favorable results.” With decades of experience in designing, manufacturing and servicing steam turbines, Dresser-Rand provides unmatched knowledge in a full range of standard products as well as custom-engineered solutions. Dresser-Rand’s worldwide installed steam turbine equipment base includes approximately 62,000 units in more than 100 countries.
