(Ⅰ)前言毛主席教导我们“人民群众有无限的创造力。他们可以组织起来,向一切可以发挥自己力量的地方和部门进军,向生产的深度和广度进军,替自己创造日益增多的福利事业。”近代大型汽鼓式锅炉的特点之一是蒸发倍率高。因此,即使给水的硬度很低,也会在受热面上生成水垢沉淀。现均采用加入磷酸盐处理,防止水垢的生成。随着锅炉参数和容量的不断提高,对炉内磷酸盐处理的要求及控制范围也越来越严格了。因此用人工分析不但劳动强度大,而且也不能及时地,准确地监督炉水质量。
(Ⅰ) Foreword Chairman Mao taught us that "the masses of people have unlimited creativity, and they can organize themselves to march into all places and departments that can exert their power, march toward the depth and breadth of production, and create ever-increasing welfare programs for themselves One of the hallmarks of modern large-drum boilers is the high evaporation rate. Therefore, even if the hardness of the feed water is low, scale deposits are formed on the heated surface. Are used to join the phosphate treatment to prevent the formation of scale. With the continuous improvement of boiler parameters and capacity, the requirements and control range of phosphate treatment in the furnace have become more and more strict. Therefore, not only labor-intensive manual analysis, but also timely and accurate monitoring of furnace water quality.
