Natural gas combustion on the surfaces of walls and heating chamber roofs of heating furnaces.
Disk-flame burner construction provides uniform heating of furnace lining till temperature 1250-1340 °С and excludes local products overheating. The rate of metal burnout is not exceed 0,5 – 1,0% in comparison with 2,0 – 2,5% for conventional methods of heating. Detail of mentioned burner construction is use of multiband air swirler with terminal resistance for maintenance of air pressure before burner no more than 1,2 kPa. It’s allow to refuse from high pressure blowers.
Realization of heating technique by radiation mainly with use of disk-flame burners provides fuel consumption reduction on 30 – 35% and heat unit capacity increase. The natural gas consumption is decreased from 70 nm3/h till 40 nm3/h for furnace with 1,75 m2 floor aria.
