Abstract
The invention relates to a novel burner nozzle field consisting of nozzle field modules which work with an intensive air pre-heating system and which produce gas impact spots on the material which is to be warmed, which have an average distance of, preferably, less than 150 mm and, in the best case, less than 100 mm. The burners work with a deignited gas outlet and an individual air pre-heating system. The individual nozzle field modules can work in any particular spatial orientation. Burner nozzle fields can be arranged behind each other in order to increase efficiency.
Claims20
A burner nozzle field, particularly for heating moving goods to be heated, comprising:
- A number of nozzle bodies (27), each including an individual air pre-heating structure (22, 45) and each of said nozzle bodies (27) having at least one nozzle opening for generating fuel air jets (32) which are directed toward the goods to be heated, but are not ignited at the point of discharge from the respective nozzle opening so as to form an un-ignited fuel-air jet (32), said nozzle bodies (27) are arranged in spaced relationship that the distance between the centers of the impact spots on the good to be heated is less than 200 mm, and wherein the nozzle openings of the nozzle bodies (27) are disposed at a distance from the combustion chamber wall (5) so as to provide for a recirculation volume between the nozzle opening and the combustion chamber wall (5), wherein the air pre-heating arrangement (22, 45) is so designed that it heats the air supplied to the nozzle bodies to above 500° C., and wherein the discharge speed of the fuel air jet (32) which leaves the nozzle opening in an un-ignited state is at least 50 m/s.
