判别下辐射区工作可靠性的水冷壁管管壁温度是与燃烧过程的组织、燃料品种、燃料量以及锅炉负荷等因素有关。为了搞清楚锅炉负荷和燃烧过程对水冷壁下辐射区温度工况的影响,在30万瓩机组ПК-41型~*双炉体燃油直流锅炉上进行了这方面的试验研究工作。ПК-41燃油锅炉每个炉膛中部有一个缩腰,把它分隔成燃烧室和冷却室二部分。在下辐射区前后墙上分别对冲布置4只容量为4.5吨/时燃油量的切向叶片双通道旋风式燃烧器。炉膛深度5.9米,燃烧器中心线间
Judgment of the reliability of the work under the radiation zone water wall tube wall temperature is related to the organization of the combustion process, fuel species, fuel and boiler load and other factors. In order to clarify the impact of boiler load and combustion process on the temperature conditions of the radiant zone under the water wall, the experimental research in this area was carried out on the 300000 unit ПК-41 ~ * double furnace fuel oil fired boiler. ПК-41 oil-fired boiler in the middle of each furnace has a reduced waist, it is divided into two combustion chamber and cooling chamber. On the front and rear walls of the lower radiation zone, four tangential blades and two-channel cyclone burners with a capacity of 4.5 tons / hour are respectively arranged on hedges. Furnace depth of 5.9 meters, between the burner center line
