Boiler Cleaning Applications

Boilers for power generation both for onsite use and for export and sale to electricity distribution companies always work most efficiently when build up on heat exchange surfaces is minimized.

Primasonics® Acoustic cleaners can be designed into boilers to minimize the size of walkways required for retractable soot blowers and to offer the all round cleaning that can be achieved with acoustic cleaning.

As Acoustic Cleaning utilises very diffractive low frequency sound waves cleaning can be achieved on all surface areas no matter how they are orientated.
This means that rather than just forcing a gas path to maintain differential pressure across the boiler acoustic cleaners clean all the heat exchange surfaces maintaining thermal efficiency as well as differential pressure.

Selective catalytic converter’s or SCR’s are used to remove NOx from flue gases. Within the unit ammonia is added to the gasses which combines with NOx to form water and nitrogen. SCRs consist of one or more banks of catalyst blocks through which the flue gas must flow. Unfortunately honeycomb catalyst blocks are often blinded and blocked due to solid particle build up.
Primasonics® Acoustic Cleaners are used to ensure the particles are excited and can be carried with the gas stream to a suitable filtration or ESP system. A partially blocked catalyst layer can disrupt flow forcing all the gasses through a small number of catalyst blocks which reduces the effectiveness of the unit. Acoustic Cleaners are used either to replace soot blowing systems when fitted to new equipment or can work along side existing flow aids when retrofitted to existing units.
