Abstract
A combustion system and a method for adapting the combustion system to utilize a first fuel when the system has been designed for a second fuel. The method and system provide inlets for adding air to lower the quality of the first fuel to the quality of the second fuel or inlets for adding a third fuel of a higher quality than the second fuel to raise the quality of the first fuel to the level of the quality of the second fuel.
Claims8
A method for adapting a performance of a combustion system for a cooking device, said method comprising the steps of:
- providing a cooking device having a cooking chamber with a heat exchanger in communication with a burner having an air inlet and being connected to a supply of a first fuel, said burner being designed for a specific quality and caloric content of a second fuel;
- determining the quality and the caloric content of the first fuel;
- and
- then adding a gas selected from additional air and a third fuel to the burner dependent on the determined quality and caloric content of the first fuel to create a mixture of the first fuel, air and the gas for burning in the burner, which mixture has the specific quality and caloric content of the second fuel.
A combustion system for heating a cooking chamber of a cooking device, said system comprising a burner having a fan discharging air into a burner shaft, said burner shaft leading to a burner discharge connected to a heat exchange of the cooking chamber, said burner having a feeder for a first fuel, said burner having a nozzle situated in the burner shaft for injecting at least a mixture of the first fuel and air into the burner shaft and an igniter downstream of the nozzle in the shaft, said system being designed to operate with a second fuel having a fixed quality and caloric content, said system having additional feeders disposed upstream and downstream of the nozzle to enable an addition of an additional fluid selected from air and a third fuel of a higher caloric content and quality than the second fuel, so that the quality and caloric content of the mixture being used in the burner can be changed to the standard of the second fuel.
