An Experimental Investigation on the Maximum Loading of a Practical Gas Turbine Combustor

Abstract

The object of this work was to know a pressure effect of the maximum loading for a practical combustion chamber at high pressure condition. Conventional loading parameter indicates inverse proportionality to the squared pressure. In present investigation, flame-out limit of a can type practical combustion chamber related good to the loading parameter only at the atmospheric condition and the maximum loading value was very much dependent on the direction of the fuel jet in the primary zone. Experimental results at high pressure condition showed rapid decrease of maximum loading as the pressure increased in the combustion chamber, especially at the range above 2MPa.
