By probably not staying in control of how much residual hardness finds its way into the boiler where alkalinity is high, and there is also a cycled up residual of silica that may easily exceed 100 mg/L, the source of scaling is clear. Getting rid of the mistake is what our topic is here. Chemical cleanings may be effective, but I feed that cryogenic treatment directly to the scale results in differential contraction that removes this silicate scale as dust.
