The controllable pulsating combustion has very strong effect on intensifying the combustion and heat transfer for its periodic violent gas flow turbulence

and is a clean combustion technology with low emission of pollutants NO

x

and smoke.The working principle

thermal system

and noise removal measures of modified Rijke pulsating burners have been presented

and comparison with traditional 0.5 t/h oil-fired boiler being carried out.Results show that the volume and shape of fuel oil pulsating boiler are similar to that of traditional oil-fired boiler

however

the furnace volume

the radiation heating surface

and the convection heating surface has reduced 55%

44.5%

and 13.5% respectively

while the heat transfer efficiency has enhanced more than 30%

the output capacity reaches 0.7 t/h

thermal efficiency to be 86%

heightening 2%

and the noise level

<

70 dB.
