The 3*180t/h circulating fluidized bed boiler of the fourth branch of Henan Xinlianxin Chemical Group Co., Ltd. has two operating modes and one standby; the boiler adopts ammonia desulfurization technology, and is equipped with two desulfurization towers, and the operating mode is one opening and one A set of wet electrostatic precipitator is installed behind each desulfurization tower. At present, the desulfurization tower does not have a purification water washing section. This transformation plans to add a water washing section to the upper part of the desulfurization tower, and add a cooler to cool the water washing liquid, and the water washing liquid exchanges heat with the flue gas to reduce the exhaust gas temperature of the desulfurization tower (below 47°C).
The flue gas effect is very obvious when the temperature of the operation purification section of the heat exchanger is 42 degrees!
