【摘要】 对WGZ410/9.8 15锅炉下联箱的沉积块状物的化学成分、显微组织和物相组成进行了检测。结合锅炉水质分析结果,确认块状物的成分是以硅的氧化物及化合物为主;锅炉水处理不当所形成悬浮或沉积的水渣,造成水冷壁上升管堵塞,最终导致锅炉爆管。提出了防止措施。更多还原

【Abstract】 The chemical composition, microstructure and phase ingredient of the sediment in the sub-header of WGZ410/9.8-15 boiler are measured. Based on the analysis of boiler water, the composition and the source of the sediment are determined. The conclusion showed that the main factor caused the tube rupture is the water quality being in the bad condition. The suspended solids and the sediments jam the rising tubes.更多还原
