Abstract
An apparatus installed between a fuel economizer and an air preheater for the denitration of exhaust gas from a coal-fired boiler includes at least one vertical flue situated upstream of a reactor containing a denitration catalyst to cause an upward flow of the gas, A hopper is located below the vertical flue for collecting ash separated from the gas, A baffle is preferably provided in the flue to ensure the still more effective separation of ash from a gas.
