The results indicate that the mass size distribution of fly-ash particles in the inlet of the WFGD system is typically disturbed bimodally, the peaks are approximate at 1 and 3 μm. And the shape of particles is regular sphericity, the mass ratio of PM2.5 to PM10 is about 0.434. The total mass concentration is about 85 mg/m3. In the outlet of the WFGD system, the mass size distribution of fly-ash particles is also bimodal. The proportion of fine particles increased, the mass ratio of PM2.5 to PM10 is about 0.764. Some fine particles are conglutinated and formed irregular agglomerate. The total mass concentration is under 23 mg/m3, the removal efficiency of total particles is 74.5%. The size removal efficiency is decreased observably with the range of particle size decreasing.

结果表明，WFGD系统入口飞灰质量粒径呈典型的双峰分布，峰值分别在1和3 mm处，颗粒多呈规则球形，PM2.5与PM10质量比为0.434，飞灰总浓度约为85 mg/m3标准状态；出口处飞灰质量粒径分布也呈现双峰性，其中细颗粒比例增大，PM2.5与PM10质量比为0.764，细颗粒间相互聚集粘连形成不规则的块状结构，飞灰总浓度在23 mg/m3以下，总飞灰的脱除效率为74.5%，分级脱除效率随粒径减小而明显下降。

It uses middle extracted steam from steam turbine to heat the feetwater of boiler to the saturate temperature under working pressure of deaerator, so as to remove dissolved oxygen and other gases. To prevent or slow boiler and steam turbine as well as pipeline from corroding, and extend them service life, to ensure the operation of the power plant under safety economic condition. The high-pressure deaeator of 235t/h is a kind of mixture-type heater, which shall match with 55 MW units, whose deaerated head adopts a kind of new-style stuffing way with rotation film.

它是利用汽轮机的中间抽汽将锅炉给水加热到除氧器工作压力下的饱和温度，以达到除去给水中的溶解氧和其它气体，防止或减缓锅炉、汽机及其管道的腐蚀，延长其使用寿命，确保电厂的安全经济运行。235t/h高压除氧器是配55MW机组的混合式加热器。

The deaeator just about takes advantage of the principle, to make water temperature raised to the saturate temperature under corresponding pressure, so that all dissolved gas in water separates out, to reach deaerating purpose.

除氧器正是利用这个原理，把水温升至相应压力下的饱和温度，促使水中原有的各种溶解气体都离析出来，从而达到除氧的目的。
