ABSTRACT:
This invention is directed to the suspension firing of a comminuted combustible material and the supporting structure for such suspension firing. The combustible material is introduced to a burner head which results in the combustible material expanding in a circular pattern. Inside of this circular pattern there is an outwardly directed flame to contact the combustible material. The result is an immediate ignition of the combustible material and the complete burning of the combustible material. There is also a refractory near the burner head. After the refractory has been heated to a desired temperature the outwardly directed flame can be discontinued and the heat energy from the refractory material is sufficient to assist in the immediate firing of the combustible material. A result of this is that an auxiliary fuel such as fuel oil or natural gas is not required, after the refractory has reached the desired temperature to sustain combustion of the combustible material. Further, with the complete burning of the combustible material there is less possibility of particulate matter being introduced into the atmosphere as pollutants and also less possibility of particulate matter condensing out on boiler tubes in a furnace. Another factor of this invention is that the burner head and supporting equipment can be removed from the hot furnace and repaired outside the hot furnace or another burner head can be introduced into the hot furnace. This means that it is not necessary to cool the hot furnace before working on the burner head.
