Dissolved oxygen in the feedwater shall be 7 parts per billion (ppb) maximum with oxygen scavenger treatment temporarily suspended. If it exceeds 12 ppb, provide recommendation to boiler plant supervisor that deaerator must be inspected and repaired. Prevent embrittlement of boiler pressure vessels. Condition the boiler sludge to obtain effective bottom blow-off. Boiler Residual of sodium sulfite, 30-60 ppm. Boiler phosphate residual, 20-40 ppm. Total dissolved solids (TDS) in boilers as high as possible, but not to exceed 4000 ppm. Total alkalinity in boilers 800 ppm maximum (1/5 x solids TDS). Maximum suspended solids in boilers 350 ppm, maximum silica 250 ppm. Boiler polymer dispersant residual as recommended by supplier. There shall be no pitting corrosion. There shall be no scale and deposit formation in the boilers Moisture content of the steam shall not exceed one percent. Perform condensate conductivity tests at a steam trap near the boiler steam outlet (at a point with no amines) to evaluate the moisture content of the steam. If necessary, utilize an antifoam agent to limit solids carryover in the steam from the boilers and to control boiler priming, foaming and misting. Control boiler water chemistry to minimize blowdown and thus improve efficiency. Provide steam amine treatment to provide condensate pH of 8.0-8.5 at each condensate receiver throughout the facility and in the condensate storage tank in the boiler plant. Feed the amines into the boilers instead of the steam header in order to achieve even dispersal throughout the distribution system. Control corrosion rates.
