水污染的毒龙300MW循环流化床锅炉机组石灰石系统的隐形杀手2

4具体改造及效果

4.1改造方案

在维持原有风机不变的前提下，取消各给料点所有的D108 mm电动门，改为每个给料点用一个D159 mm的电动门与一个同口径的手动门相串联，正常启、停只需操作电动门，而手动门只作系统检修隔绝使用。在管道方面：将1号混合器出口至第1级分配器入口的D273 mm×10 mm管道更换为D219 mm×10 mm管道，分配器后面出来的2路D159 mm×8 mm管道不动，至1、4号料腿正中间上方后弯转向下，与1、4号料腿的给料点连接，即1号石灰石给料线只供1、4号料腿，形成1号与4号以中心线对称布置；而将2号混合器出口至4个料腿的所有管道全部废除，混合器旋转180°后，重新铺设D219 mm×10 mm管道直至2、3号料腿正中间上方，变径为2路D159 mm×8 mm分管与2、3号料leggiving line only supplies 2 and 3 nozzles, forming a symmetrical layout with the centerline, achieving the purpose of single-line dual-point feeding (see Figure 2).

4.2改造效果

After the system is completely renovated, it undergoes another trial run under no-load conditions, and the mother pipe pressure drops to around 9-10 kPa; compared to line No. 2, line No. 1's pressure is slightly lower by about one kPa, indicating that pipe losses have been significantly reduced; without any control program running during powder injection testing, the mother pipe pressure gradually rises as the rotating feeder valve speed increases steadily, with no powder accumulation observed in all pipes; at identical speeds for both lines No. 1 and No. 2 begin experiencing dramatic fluctuations in their respective pressures when their rotating feeder valves exceed a speed of over half their maximum capacity.

The ultimate confirmation was made after extensive tests: under normal operation with variable frequency drives outputting at or below half-speed (50%), both lines can maintain stable operation up to a maximum temperature range of approximately between -40°C and +50°C while maintaining high efficiency levels within an optimal operating range.

Further analysis reveals that these modifications have not only improved overall system performance but also increased energy efficiency through optimized process parameters resulting from better material flow management strategies implemented within this new design configuration.

Moreover, due to its highly efficient combustion characteristics along with advanced pollution reduction techniques employed throughout this project’s implementation phase – such as advanced flue gas cleaning technologies – emissions from this newly designed system will be significantly lower than those produced by traditional systems currently in use worldwide today!
