Boiler Efficiency and Steam Quality: The Challenge of

To affect either of the above, use modulating versus on-off valves at steam-use points. Add boiler feedwater with modulating versus on-off controls. Use TDS controls rather than time-based blowdown. Operate the boiler near its maximum design pressure. When any of these recommendations are not followed, reductions in steam quality can be dramatic.
