ferred to the auxiliary power supply. At a mercury flow rate of 400 pounds per hour (180 kg/hr), valve V-217 was opened so that the mercury inventories of the boiler and condenser could be transferred to the standpipe. During the removal of mercury in- ventory, the mercury flow to the turbine alternator wasLearn More

Mercury (Hg) and selenium (Se) are two of the volatile trace metals in coal, which are often not captured by conventional gas clean up devices of coal-fired boilers. An alternative is to use sorbents to capture the volatile components of trace metals after coal combustion. In this project sorbent screening tests were performed in which ten sorbents were selected to remove metallic mercury …Learn More
