The report gives results of a second survey of the flue gas desulfurization (FGD) system on Unit 1 of Arizona Public Service Co.'s Cholla Station. The FGD system, commercially available in December 1973, uses a limestone slurry in two parallel scrubbing modules to control SO2 and fly ash from the combustion of low sulfur western coal. (The two-module FGD system is described.) The system's total SO2 removal efficiency is 58.5% (92% for the SO2 removal module). Either or both modules can be bypassed. The flue gas cleaning wastes are disposed of in an on-site unlined fly ash pond. No water is recycled from the pond to the FGD system. Following a number of modifications of the FGD system by the system supplier and the utility, the system has exhibited a high degree of mechanical reliability while meeting required SO2 and particulate emission control levels.
