Abstract

Ce dispositif permet l'emploi de combustibles solides pulvérisés pauvres (charbon, lignite, tourbe) et de leurs dérivés pendant les périodes de démarrage à froid et de soutien aux basses charges chambres de combustion. This device allows the use of solid fuels poor pulverized (coal, lignite, peat) and their derivatives during cold start periods and support for low load combustion chambers.

Le brûleur d'allumage (1) comporte un allumeur d'ap­ point et d'alllumage fonctionnant avec du gaz produit par la gazéification (6) du combustible pauvre et un allumeur principal fonctionnant avec le combustible pauvre pulvérisé (5). L'air de combustion est réchauffé (10) par le gaz produit par la gazéification (6). En particulier, l'air de combustion envoyé à la sortie de l'allumeur d'allumage est mis en turbulence. The ignition burner (1) has an ap igniter ignition point operating with gas produced by the gasification (6) of lean fuel and an igniter main working with pulverized lean fuel (5). The combustion air is heated (10) by the gas produced by gasification (6). In particular, the combustion air sent to the ignition igniter output is turned on turbulence.

Application: Appareils divers à combustion y compris les générateurs de vapeur des centrales thermiques. Application: Various combustion appliances including steam generators in thermal power plants.
