Applications Of Soot Blower:
Benefits of Sonic Cleaning:
Sonic Soot Blower based on the principles of kinetic activation of dust particles using sound waves at frequencies that are normally between 125-400 Hz. The sound waves are generated by a special bell shaped sound emitter powered by air and controlled electrically by a solenoid valve. The kinetic energy imparted to the dust particles cause them to vibrate, break their bonds with other particles and the surface to which they cling. These fluidized particles are then dispersed by gravity or by gas stream pressure.These sound waves can also be used to fluidize dust to facilitate removal from hoppers, bins etc. Where ever there is a problem with dust plugging , dust build or dust flow , the system may provide the answer to the problem High energy low frequency Sonic power systems are engineered and designed for corrosive and high temp. Environments. Their fundamental frequencies at 142 Db are in the optimum range to fluidize soot and dust clinging to the tubes and surfaces.The sound waves are generated in a special sound emitter which is designed to withstand temperatures of as much as 1000 deg. C, so that it can be mounted almost at any point on the boiler wall.
Benefits of Sonic Soot Blowing:
No requirement of costly steam - works on pressurized service air ( at 5-6 kg/ cm2 )
Fully Automatic continuous cleaning - controlled by a microprocessor, the system works on-line continuously, as per designed program & keeps on cleaning the equipment with increased efficiency.
Effective cleaning - Sonic leaning achieves a uniform cleaning effect & cleans the inaccessible areas also.
Reduced operating costs -operating cost of sonic blower is very less, it requires compressed air only during the isolation period & rest of the time air is not required.
Increased equipment availability - sonic cleaning drastically reduces the equipment downtime by keeping clean the system.
Low maintenance - there are no moving parts & design features are very simple so the sonic system requires very minor service.
