近年来,采用旋风燃烧的锅炉有了很大的发展。1954年,美国投入运行和在建设中的旋风炉即有35台,总容量为9535吨/时;最近还在继续试验和建设一些燃烧多种燃料的大容量旋风炉。在德国到1955年上半年为止,已经投入运行和正在建设中的旋风炉共有38台,总容量为5133吨/时。英国和日本近几年来也在积极从事旋风炉的研究与试验工作。苏联在1944—45年就开始了燃烧向日葵壳子的旋 In recent years, the use of cyclone boiler has made great progress. In 1954, there were 35 cyclone furnaces in operation and under construction in the United States with a total capacity of 9,535 tons / hour. Recently, large-capacity cyclone furnaces for burning multiple fuels have been continuously tested and constructed. In Germany until the first half of 1955, a total of 38 cyclone furnaces were in operation and under construction with a total capacity of 5133 tons / hour. Britain and Japan are also actively engaged in the research and experimental work of cyclone furnaces in recent years. The Soviet Union started burning the sunflower shell in 1944-45
