High-Pressure Steam Cycle and Boiler Water TreatmentIn order to increase steam production, lignin removed from bagasse, 50% of available sugarcane trash and the rest of cellulose (the fraction not hydrolyzed) are sent to the boiler. The co-generation system is comprised of a boiler of 90bar and two back-pressure turbines in series (exhausting pressures, respectively, of 22bar and 2.5bar) followed by a condensing turbine.Operation Experience, Operation Procedures In Supercritical And Ultra Supercritical BoilersTurbine steam must generally have total dissolved solids less than 0.050 ppm, and in some cases less than 0.030 ppm. Individual species limits may be even lower. If steam is to be superheated, a maximum steam dissolved solids limit must be imposed to avoid excessive deposition and …

In some steam drum designs, water level is extremely critical because the baffling may isolate a generating section of the boiler when the steam drum water level falls below a certain point. Thin-lipped bursts also occur in superheater tubes when steam flow is insufficient, when deposits restrict flow, or when tubes are blocked by water due to a rapid firing rate during boiler start-up.
