某热电厂锅炉在运行过程中，中部床温与左右两侧床温偏差达110℃，给运行人员优化调整带来困难。针对上述问题，该电厂开展了运行数据分析、风帽改造方案设计、改造效果分析等一系列工作。对该型锅炉中部区域的风帽进行适当节流，降低通过中部区域风帽的空气流量后，锅炉床温偏差普遍明显降低，基本将床温偏差降低至50℃以下，改造效果良好。

The bed temperature deviation between the middle and both sides of the furnace reaches 110℃in oper-ation, which added the operation difficulties of a thermal power plant.Focusing on the above problem, some re-searches had been carried out, such as the analysis of operating data, the design of hood reconstruction program and the effectiveness analysis of hood reconstruction, etc.Finally the throttling reconstruction of hoods was carried out to reduce the air flow through the central region of the furnace, the temperature deviation has been significantly improved, which dropped below 50℃on the whole.
