Before installation of Shock Pulse Generator:
Year 2010, after 10 weeks of boiler operation
Large slagging / deposits are visible at the membrane walls and at the refractory.
Several times, large size slag lunks were falling down after some time due to heavy weight and blocked the deslagger or damaged the stoker
After installation of the Shock Pulse Generator: Year 2015, after 12 weeks of operation
Slag and deposits are cleaned off from membrane wall and from refractory by the Shock Pulses of the SPG.
There were no further blockages of the deslagger, nor damages to the stoker.
