石油价格的上涨,重新引起了利用煤作为能源的高度重视。各国正在研究各种高效而又不污染周围环境的煤的燃烧过程及其相应的技术设备,以便获得更多的电能。这类设计方案之一是利用所谓压力沸腾层的概念。英国计划研制一种用于发电厂的燃煤的新型锅炉,即所谓的压力“沸腾”层炉膛(也就是假液化层燃烧炉膛)。其原理见附图。 The rise in oil prices has rekindled the great importance of using coal as an energy source. Countries are studying various efficient and non-polluting coal combustion process and its corresponding technical equipment, in order to obtain more electricity. One of these design options is the concept of using so-called pressure boiling layers. The UK plans to develop a new type of coal-fired boiler for power plants, the so-called pressure “boiling” layer of the furnace (ie, the fake liquefied layer). The principle is shown in the attached drawings.
