This Ultra-Compact Combustor (UCC) is fed air with a bulk swirl, resembling gas leaving a compressor without the final set of compressor guide vanes to straighten the flow, at higher than normal Mach numbers for a combustor. The larger Mach numbers in the combustor do not cause a total pressure loss in excess of what Rayleigh theory would.

A gas turbine, also called a combustion turbine, is a type of continuous and internal combustion main elements common to all gas turbine engines are: an upstream rotating gas compressor; a combustor; a downstream turbine on the same shaft as the compressor.; A fourth component is often used to increase efficiency (on turboprops and turbofans), to convert power into . The combustion behavior is evaluated using normal and preheated air at inlet to the combustor. Experimental results from the distributed combustor design using methane fuel showed low levels of NO (high heat release intensity of 36MW/m 3-atm.
Downloadable (with restrictions)! Distributed combustion offers significant performance improvement with near zero emissions for industrial gas turbine applications. Our efforts to further develop zero emission distributed combustion are explored here by utilizing swirl to the flow. The beneficial aspects of distributed swirl combustion using a cylindrical geometry combustor has shown low. 2 Gas Turbine Power Plants Gas turbines are thermodynamic systems that use fuel and air to produce a positive work transfer. They convert the chemical potential energy of the fuel to mechanical energy. The gas turbine operates on an open cycle consisting of a compressor, a combustor, and a turbine combined in series (Figure 2).

The innovative ultra-compact combustor (UCC) is an alternative to traditional turbine engine combustors and has been shown to reduce the combustor length and offer potential improvements in combustion efficiency.
Prior UCC configurations featured a circumferential combustion cavity positioned around the outside diameter (OD) of the engine. The experimental results confirm that this type of high-g T a g g e d P loaded system has great potential to be used as an ultra-compact combustor for a main burner, or as an inter-turbine burner.
Ultra-Compact combustion presents a novel solution to address the demand for increasingly compact, efficient, and low weight aircraft gas turbine engine propulsion systems.

Flashback was demonstrated to be a factor highly high Reynolds number (Re). All these results were intended to contribute to better designs of future combustors. Gas turbine combustors have seen considerable design changes. The original diffusion type combustors were changed to wet combustors by adding water or steam in the combustion zone to restrict the amounts of NO x produced.
Most new turbines have progressed to DLE NO x combustors from the wet diffusion type, which were injected by steam in the primary zone of the combustor. Optimization of gas turbine combustor performance throughout the duty cycle Symposium (International) on Combustion, Vol.

It comprised laboratory-scale swirl burner; operating at ambient pressure, fired vertically upwards with flame stabilized at the end. Gas turbines are extensively used in combined cycle power systems.
These form about 20% of global power generating capacity, normally being fired on natural gas, but this is expected in the future to move towards hydrogen enriched gaseous fuels to reduce CO2 emissions.
Gas turbine combined cycles can give electrical power generation efficiencies of up to 60%, with the aim of increasing this to. intensity. Furthermore, aero engines combustor operates over a wide range of inlet temperatures, fuel-air ratios at flight altitudes with the result that the combustion performance may deteriorate at high altitude.
Combustion efficiency of a gas turbine depends on various processes taking place in the combustor primary Size: KB.
