L'invention concerne un procédé de fonctionnement d'un brûleur hybride (20) présentant un brûleur à prémélange (22) et un brûleur pilote (21). Le brûleur à prémélange (22) comprend un canal d'acheminement d'air de prémélange (4) dans lequel débouche un canal d'acheminement de combustible de prémélange (8, 12, 16). Le brûleur pilote (21) comprend un canal d'acheminement d'air (3) et un canal d'acheminement de combustible (1, 2) pour du combustible liquide et/ou gazeux. Lors du fonctionnement du brûleur hybride (20), de l'air est acheminé par l'intermédiaire du canal d'acheminement d'air (3) et par l'intermédiaire du canal d'acheminement d'air de prémélange (4), de l'huile est acheminée par l'intermédiaire du canal d'acheminement de combustible (1) et de l'eau est acheminée par l'intermédiaire du canal d'acheminement de combustible de prémélange (8, 12, 16).
