One small change in boiler feed level control, one massive

With most sites, the better the steam quality, the less water retention within the steam." So with high-quality steam, "You get a cleaner actual path into the product or the heating system and better heat transfer. You don't see as much condensate." Scott says the problems at Grant's were due to the level control on the boiler feed.
