FIELD: power industry.
SUBSTANCE: invention refers to power industry. Method of switching fuel feed to combustion chamber from pre-mixed first fuel to premixed second fuel involves reduction and stop of premixed first fuel feed and further start of premixed second fuel feed. In the intermediate phase after termination of premixed first fuel feed and before the start of premixed second fuel feed, combustion chamber operates with pilot oil of one or more types, generating diffusion flame only.
EFFECT: increased operation life of equipment.
