Claims (1)
塵器で分離した後の排ガスを、通風機により熱交
換器を介して脱硫装置に導き、且つ脱硫後の排ガ
スを前記熱交換器により昇温して排出する排ガス
流路において、前記通風機出口と熱交換器入口と
の間のガス流路に、前記電気式集塵器によつて分
離した煤塵の一部を注入する煤塵注入流路を接続
したことを特徴とする熱交換器の低温腐食防止装
置。 After the soot and dust in the exhaust gas from the coal-fired boiler is separated by an electric precipitator, the exhaust gas is guided to the desulfurization equipment via a heat exchanger by a ventilator, and the temperature of the exhaust gas after desulfurization is raised by the heat exchanger. A part of the dust separated by the electric precipitator is injected into the gas flow path between the ventilator outlet and the heat exchanger inlet in the exhaust gas flow path for discharging the dust. A low-temperature corrosion prevention device for a heat exchanger, characterized in that it is connected.
