Fouling in waste heat boilers | Газогенераторы МС

Sometimes steam-side fouling is caused by deposition of salts from steam. Steam-side fouling can increase the tube wall temperatures and cause overheating as discussed in Q8.13. Steam-side fouling is more critical in finned water tube boilers, as discussed in Q8.24. One has to shut down the boiler and perform an investigation if fouling is severe.
