US Patent:

7603841, Oct 20, 2009

Filed:

Feb 28, 2006

Appl. No.:

11/365969

Inventors:

Robert C. Steele - Woodinville WA, US
Ryan G. Edmonds - Renton WA, US
Joseph T. Williams - Kirkland WA, US
Stephen P. Baldwin - Winchester MA, US

Assignee:

Ramgen Power Systems, LLC - Bellevue WA

International Classification:

F23R 3/18

US Classification:

60 39465, 60737, 60749

Abstract:

A trapped vortex combustor. The trapped vortex combustor is configured for receiving a lean premixed gaseous fuel and oxidant stream, where the fuel includes hydrogen gas. The trapped vortex combustor is configured to receive the lean premixed fuel and oxidant stream at a velocity which significantly exceeds combustion flame speed in a selected lean premixed fuel and oxidant mixture. The combustor is configured to operate at relatively high bulk fluid velocities while maintaining stable combustion, and low NOx emissions. The combustor is useful in gas turbines in a process of burning synfuels, as it offers the opportunity to avoid use of diluent gas to reduce combustion temperatures. The combustor also offers the possibility of avoiding the use of selected catalytic reaction units for removal of oxides of nitrogen from combustion gases exiting a gas turbine.
