4) ESP HOPPER HEATERS
Hopper heaters for efficient removal of ash on electrostatic precipitator
normally called ESP Hopper Heaters. Due to Flue gas condensation ,Fly ash
hoppers experience 'pluggage' problems. Marathon supplies electric surface
heating system for fly ash hoppers on electrostatic precipitator in all type of
industries who face the problem of blockage in Hoppers. The blockage is so
severe that often pneumatic drilling equipment and explosives are required to
free the system. This problem, known as Flash Freezing, is extremely
inconvenient and very costly.
Due to moisture content and low temperature inside hoppers, choking &
accumulation of fly ash occurs to maintain temperature inside hoppers for
effective flow of fly ash to ash disposal system. to remove these kind of
problems, we have to use ESP hoppers heaters, so that they heat up the hopper
and hopper get clean which got blocked by dust & ash.
