FIELD: power engineering; burning fuel in various thermal plants and heat exchange apparatus.
SUBSTANCE: proposed multi-jet burner has combustion chamber which is closed on one side and is provided with outer and inner perforated tubes; it is made in form of double tube and is provided with distributing unit for smooth distribution of gas-and-air mixture; it is made in form of cone mounted in inner tube with its vertex directed towards gas-and-air mixture flow; ratio of diameter of outer tube to diameter of inner tube is no less than 1.2 and ratio of area of holes of inner perforated tube to area of holes of outer perforated tube is no less than 1.7. proposed burner excludes back-flash and enhances stable operation due to smooth distribution of gas-and-air flow, thus ensuring stable combustion over entire length of burner.
EFFECT: enhanced safety and reliability.
