ABSTRACT:
A burner is provided for heating a stream of combustion supporting gas, like air. The burner has a main feed pipe extending across the stream of combustion supporting gas. The main feed pipe has an inlet for receiving a fuel gas from a fuel gas source, and at least one outlet for producing a main jet of fuel gas substantially in the direction of the stream. The burner also has two parallel auxiliary feed pipes extending across the stream of combustion supporting gas, at a predetermined distance downstream from the main pipe and on each side of the main jet. Each of the auxiliary feed pipes has an inlet for receiving fuel gas from the fuel gas source, and at least one outlet for producing an auxiliary jet of fuel gas in the direction of the stream. The burner further has two bluff-body devices in front of the outlets of both the auxiliary feed pipes respectively. Each of the bluff-body devices has a hole aligned with each corresponding outlet in order to produce a stable pilot flame adjacent to the main jet of fuel gas for ignition thereof. This burner is useful since it allows for a better mixing of the fuel gas with the stream of combustion supporting gas. Such in turn allows for a better combustion of the fuel gas and, hence, a reduction of pollutant emissions.
