Abstract
A fuel staging system comprises a splitter valve arranged to split an input fuel stream into a pilot fuel stream and a main fuel stream, the splitter valve comprising a spool slidable within a bore, the spool and bore together defining first and second control chambers, the fluid pressures in which determine the position occupied by the spool, the system further comprising a control line which, in use, controls fuel delivery through a plurality of main burners, the fluid pressure in the control line being a combination of the fluid pressures in the first and second control chambers.
