Title: Gas turbine combustor
Inventor: TSUKAHARA SATOSHI
IPC: F23R3/26
Filed: 1990-09-14
Abstract: PURPOSE:To reduce NOX discharge concentration and to reduce incurring of a pressure loss during low load operation by a method wherein a flow rate control valve for air for generating air-fuel premixture is provided, a plurality of fuel nozzles are divided into a plurality of sets, and a fuel flow rate and an air flow rate for generating air-fuel premixture are controlled according to a load. CONSTITUTION:Fuel fed in an inner cylinder 101 through a fuel nozzle 103 is burnt in a combustion chamber 115 as the fuel is mixed with air entering in a swirl state through an air hole 108. Meanwhile, fuel fed in a premixing chamber 114 through a nozzle 104 is mixed with air entering in a swirl state through an air hole 109 and air from an air hole 107 through an air hole 116 having a flow rate control valve 106 to produce combustible air-fuel premiture, which is burnt in the combustion chamber 115. A fuel flow rate control valve selects a system through which fuel is fed and a system through which no fuel is fed and controls a fuel flow rate of each system as a whole fuel flow rate responding to a load is fed. The air flow rate control valve 106 located at the inlet of a premixture chamber controls an air flow rate fed to the premixture chamber. This constitution causes the flow of a whole fuel flow rate, responding to a load, through the fuel nozzles 103 and 104 during high load operation and keeps a flow rate ratio between fuel and air at a given value.

IPC: G06F17/50
Filed: 1993-09-29
Abstract: PURPOSE: To provide an improved structure designing system and its method. CONSTITUTION: The sensitivity of a performance function (Sensitivity Data Set: SDS) in a circuit is decided for at least one physical parameter at first (step 30). Then, the estimated distribution of a design function is calculated through the user of an SDS value and a random parameter value (step 40). As a result, a tail is correctly calculated through the use of the parameter corresponding to the estimated distribution (step 50) and compared with a prescribed design target (step 60). Unless the prescribed set target coincides with the calculated tail, design is changed (step 70) and a calculation step is repeated till both coincide.
