A leadership position in dry low emissions (DLE) technology is being claimed by Rolls-Royce Industrial & Marine Gas Turbines. Following a US$38 million development program, the first Coberra 6000 (RB211) gas turbine fitted with a DLE combustion system started commercial service in 1994 at a gas transmission station in Washington State, U.S.A. A major advantage of the technology is that it can be retrofitted to existing RB211 machines simply by exchanging the combustion module. A typical conversion time, depending on the particular package confirmation, is said to be about five to eight weeks. The RB211 gas turbine comprises five modules, each fully interchangeable with similar factory-overhauled and balanced replacements. The DLE version of the combustion module is fitted with nine combustor cans situated around the periphery of the chamber. This provides the extra phased combustion technology without increasing the length. This paper describes the performance, operation and exhaust emission aspects for these turbines.
