Abstract
A fuel control system for a premixed lean burn combustor in a combustion turbine engine, the combustor having at least two stages (P,S,T), the control system including; an air flow evaluation module having means utilising an iterative algorithm to derive an accurate value of total air flow to the combustor, the evaluation module further having means dividing the derived total air flow value into the proportions (Mp, Ms, Mt) required by the combustor stages (p,s, t) and outputting signals in parallel representing the air flow to respective combustor stages (p,s,t), and a control module associated with each stage (p,s,t) of the combustor and responsible for setting the fuel demand signal for the associated combustor stage (p,s,t), each control module being adapted to set the fuel demand signal with reference to an appropriate one of said output signals.
