Abstract
The present invention provides a valve and a low pressure drop combustor bypass. The valve simultaneously controls both the supply of air to the premixer, and the amount of air directed into a large bypass duct. Air entering the bypass duct is reintroduced into the gas flowpath as dilution air downstream of the combustion zone. At low power settings the valve directs most of the air to the bypass duct, in effect bypassing the fixed area dilution ports, whereby the pressure drop across the combustor may be controlled at an optimal level.
