Abstract:
An air pollution control system includes adenitration device that removes nitrogen oxide in flue gas from a boiler; a heat transfer tube for recovering part of heat of the flue gas after denitration; a precipitator that removes soot and dust in the flue gas after heat recovery; a desulfurization device that removes sulfur oxide in the flue gas discharged from the precipitator; a heat transfer tube for heating the flue gas discharged from the desulfurization device; a circulation pump that circulates a heat medium between the heat transfer tubes; a heat medium heater provided to the circulation pipe to heat the heat medium; and a control device that controls the heat medium heater based on an ammonia concentration at an outlet of the denitration device. The control device causes the heat medium heater to heat the heat medium when the ammonia concentration is higher than a certain value.

Claim (Index 1):
An air pollution control system, comprising:\n a denitration device configured to remove nitrogen oxide in flue gas from a boiler; a heat recovery unit including a heat transfer tube for recovering part, of heat of the flue gas after denitration; a precipitator configured to remove soot and dust in the flue gas after heat recovery; a desulfurization device configured to remove sulfur oxide in the flue gas discharged from the precipitator; a reheater including a heat, transfer tube for heating the flue gas discharged from the desulfurization device; a heat medium circulation pipe including a heat medium circulation pump configured to circulate a heat, medium between the heat transfer tube of the heat recovery unit and the heat transfer tube of the reheater; a heat medium heater provided to the heat medium circulation pipe to heat the heat medium; a detection device configured to detect a state of ammonia at an outlet of the denitration device; and a control device configured to control the heat medium heater based on a value of an ammonia concentration detected by the detection device, wherein the control device is configured to cause the heat medium heater to heat the heat medium when the ammonia concentration is equal to or higher than a certain value.
