Ammonia Injection

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.

Illumination Mode

The tilted beam illumination method is used to improve the resolution comparing with the axial illumination mode. Using this advantage, a restoration method of several tilted beam images covering the full azimuthal range was proposed by Saxton, and experimentally examined. To make this technique more reliable it seems that some practical problems still remain. In this report the restoration was attempted and the problems were considered. In our study, four problems were pointed out for the experiment of the restoration. (1) Accurate beam tilt adjustment to fit the incident beam to the coma-free axis for the symmetrical beam tilting over the full azimuthal range. (2) Accurate measurements of the optical parameters which are necessary to design the restoration filter. Even if the spherical aberration coefficient Cs is known with accuracy and the axial astigmatism is sufficiently compensated, at least the defocus value must be measured. (3) Accurate alignment of the tilt-azimuth series images.
