“It was more exciting than a thesis, to work directly with commercial products and have a direct impact on the aerospace industry,” said Calvin Cai, a Seattle, Washington native who is pursuing a master’s degree in mechanical engineering. Everyone wanted to see students and faculty launch a Learjet to test sensors developed by Sensatek Propulsion Technology. Results of these models are presented and compared to the test results.Along with a television camera crew, a small group of curious onlookers recently gathered next to the airline on the Embry-Riddle Aeronautical University campus in Daytona Beach, Florida. Additionally, Westinghouse has been conducting computational fluid dynamic (CFD) and chemical kinetic studies to assist in the design of the combustor and to help optimize the operation of the combustor.
#Westinghouse j34 combustor update
This paper provides an update on the development and testing of this MASB combustor.

The application requirements indicate that a rich-quench-lean (RQL) combustor is necessary and the multi-annular swirl burner (MASB) was selected for further development. The 1600☏ (870☌) oxidizer must also be utilized to cool the combustor as much as possible, though a small amount of compressor discharge air at a lower temperature 700☏ (about 370☌) may be used. Oxidizer has been cleaned of particulates and alkali by HGCU system, and has also been partially depleted in oxygen.

The fuel must be burned with the vitiated air from the pressurized fluidized bed combustor (PFBC). The fuel-bound nitrogen is significant because it will selectively convert to NOx if the fuel is burned under the highly oxidizing conditions of standard combustion turbine combustors. It also contains significant fuel bound nitrogen present as ammonia and other compounds. The syngas entering the topping combustor has been previously cleaned of particulates and alkali by the hot gas cleanup (HGCU) system. The topping combustor in this cycle must utilize a low heating value syngas from the carbonizer at approximately 1600☏ (870☌) and 150 to 210 psi (1.0 to 1.4 MPa). This paper concentrates on the design and test of the topping combustor. Westinghouse is participating in the development of the high temperature gas cleanup equipment and the topping combustor. Since this temperature is well below the current combustion turbine combustor outlet operating temperature of 2350☏ (1290☌) to reach commercialization, a topping combustor and hot gas cleanup (HGCU) equipment must be developed. Both these units operate a nominal 1600☏ (870☌) for optimal sulfur capture. Foster Wheeler is developing a carbonizer (a partial gasifier) and a pressurized fluidized bed combustor.
