In addition to BBQ, it is possible to grill in the Q-series smokers, for that purpose we have developed a special coal tub. The coal tub must me placed to the bottom of the smoke drawer, the fat tubs must be removed. The specific shape and the perforation of the material of the coal tub guarantee a sufficient air circulation, as a result the coal stays “vivid”. The intensity of the air circulation can be regulated with the shutters that are at the ends of the chimneys and with the door of the heating compartment. It is possible to grill using grilling coal or grilling briquette. Grilling coal can be “produced” before grilling in the heating compartment by burning firewood, as a result of this the coal is generated.
