multi-boiler multi-fuel plants that also have steam turbines. To most people, this is not intuitively Low-pressure steam that is produced through a pressure letdown station, usually a pressure-reducing Therefore, it will be superheated, and the normal practice is to desuperheat it using condensate. The low-pressure steam cost is then
Heat loss from the boiler jacket could range from 1/2% to 4% of the boiler output, depending upon operating pressure or temperature, boiler size, type of construction, and insulation thickness. Typically, the larger the boiler the lower the loss as a percentage of boiler output.
discusses the basic steps in the kraft recovery process, problems encountered and challenges in recovery thermal efficiency of the recovery boiler. The high pressure steam is passed through a steam turbine to and CO concentrations during normal operation are typically only a few hundred ppm. However, CO
