Abstract (en)
[origin: CA2003021A1] A device is divulged for controlling and regulating the gas supply to the burner of a boiler or similar, which device comprises a piloted regulator (R) with a leak valve (8) for the gas flow. The burner is also fed with pressurized air and opening of the leak valve is slaved to the flow of this pressurized air so that the ratio between the two air and gas flows permanently has a value providing excellent combustion of the air-gas mixture in the burner.
Abstract (fr)
Il s'agit d un dispositif pour commander et régler l'alimentation en gaz du brûleur d'une chaudière ou analogue, dispositif comprenant un régulateur piloté (R) à valve de fuite (8) pour le débit du gaz. Le brûleur est également alimenté en air sous pression et l'ouverture de la valve de fuite est asservie au débit de cet air sous pression de façon à donner en permanence au rapport entre les deux débits d'air et de gaz une valeur assurant une excellente combustion du mélange air-gaz dans le brûleur.
