河南省鹤壁万和发电有限责任公司２ 号炉是配２００ＭＷ 机组的６７０ｔ／ｈ 燃煤粉四角切圆燃烧锅炉，１９９８ 年３ 月应用浙江大学热能工程研究所开发的双稳可调浓淡煤粉燃烧器对原第二、第三层直流燃烧器进行改造。改造后连续运行至今的实践表明：在４５％ ～５０％ 负荷下调峰，可不投助燃油稳定燃烧。在同样工况下，改后的飞灰可燃物含量在高负荷（２００ＭＷ）和低负荷（１００ＭＷ）时分别从１．８３％ 和１．３２％ 下降到１．１２％和１．１７％ 。取得良好节油经济效益。图６ 表９ 参４
Henan Hebi Wanhe Power Generation Co., Ltd. No.2 furnace is a 670t / h coal-fired tangentially fired boiler with 200MW unit. In March 1998, the bistable tunable phreatic pulverized coal combustion developed by Zhejiang University Institute of Thermal Energy Engineering The original second, third layer of the DC burner to transform. After the transformation of the continuous operation of the practice so far shows: 45% ~ 50% load under the peak, the fuel can not be used to support a stable combustion. Under the same conditions, the combustible content of fly ash decreased from 1.83% and 1.32% to 1.12% and 1.17% at high load (200MW) and low load (100MW) respectively. Achieve good economic benefits of fuel-efficient. Figure 6 Table 9 参 4
