Common Steam Boiler Problems & How to Troubleshoot Repairs
As with other boiler problems, clean the boiler of any contamination caused by foaming before correcting the water chemistry problem. Treating the water with anti-foaming agents prevents the chain reaction caused by foam production. The chemicals alter the surface tension to prevent any solids from creating foam in the water.
