Applicability of SO2-Control Processes to Power Plants.

摘要

The report describes and discusses the work undertaken in a study which proposed to determine the extent to which SO2-control units can be installed in existing oil-and coal-fired power plants. In this,and a previous similar study, 14different power systems were evaluated having a total oil-and coal-fired generating capacity of 88,520megawatts of which 78% had adequate space for retrofitting scrubbers. To obtain an indication of installation costs, a qualitative retrofit complexity factor was estimated for each boiler unit studied by considering such items as space availability,site assessibility,and degree of plant modification. The complexity factor relates the cost of retrofitting a control system to the cost of the same system installed on a new power plant. The distribution of relative operating costs over generating capacity was also calculated.
