Abstract:
1. An air-gas mixing assembly adapted to be coupled to an endothermic generator comprising: a gas inlet line constructed and arranged for coupling to a pressurized source of a hydrocarbon gas; an air inlet line constructed and arranged for coupling to a pressurized source of air; an air-gas junction communicating with the gas inlet line and the air inlet line and with the endothermic generator; and an injection valve assembly in the gas inlet line upstream of the air-gas junction, through which a volume of hydrocarbon gas is injected under pressure into the air-gas junction, the injection valve assembly including a controlled member that regulates the volume of the hydrocarbon gas injection in response to a control signal thereby providing a controlled mixture of air and hydrocarbon gas to the endothermic generator.
