GAS TURBINE COMBUSTOR WITH FUEL RATE CONTROLLABILITY

摘要

PURPOSE: A gas turbine combustor capable of controlling a fuel supply amount is provided to supply the same amount of fuel to each of multiple combustor cans by maintaining the same fuel supply differential pressure about the combustor cans, thereby maintaining a temperature of flame in each of the combustor cans to be constant. CONSTITUTION: A gas turbine combustor includes a manifold, multiple combustor cans (120) and multiple variable orifices (130). The manifold includes multiple outlets. The combustor cans formed to combust the fuel are respectively connected to the outlets to receive fuel from the manifold. The variable orifices corresponding to the combustor cans control a fuel supply amount for each of the combustor cans.
