Claims (11)

  1. Ensemble de brûleur pour appareil mobile chauffable, en particulier pour appareil mobile de cuisson (10), présentant
    un brûleur (20) produisait une flamme, une chambre de combustion (22) dans laquelle débouche la flamme du brûleur (20) et un conduit (24) d'évacuation de fumée qui conduit de la chambre de combustion (22) à une sortie (42) de gaz de fumée,
    le conduit (24) de gaz de fumée présentant une première longueur définie (LA) de conduit et présentant en outre un conduit de dérivation (38) qui conduit du brûleur (20) à la sortie (42) de gaz de fumée,
    le conduit de dérivation (38) présentant une deuxième longueur définie (LB) de conduit plus courte que la première longueur (LA) de conduit, caractérisé en ce que
    le conduit (24) de gaz de fumée est plus long que le conduit de dérivation (38) d'un facteur de 10 ou plus et
