The Experimental Study of SO₂ Removal by Atomized Ammonia Injection in the Tail Flue of a 300 MW CFB Boiler

Abstract:

An experimental study on the desulfurization system by atomized ammonia injection was conducted in the tail flue of a 300MW CFB boiler. The tests was going under the unit load ranges from 229.5MW to 267MW with ammonia concentration of 5.2~9% and flow at 3.7~9.0 t/h, the gas temperature at 145~149°C, the maximum final desulfurization efficiency is 55.6%, the average removal efficiency at 21% ~ 26%. The ammonia also has an activation function to the CaO in fly ash, which counts 15.7% to 29.8% of the total amount CaO in fly ash.
