高炉用高风温是现代炼铁技术发展的标志之一。热风不仅是高炉生产所需热量的主要来源之一,而且供给了燃料燃烧所需氧量。提高风温不仅节省焦炭,并可加大喷吹量。风温与节焦的关系见表1。为获得高风温,传统的内燃式热风炉 Blast furnace with high temperature is one of the hallmarks of the development of modern ironmaking technology. Hot air is not only one of the major sources of heat required for blast furnace production, it also supplies the amount of oxygen needed to burn the fuel. Increase the temperature not only save coke, and can increase the injection volume. The relationship between air temperature and section coke is shown in Table 1. In order to obtain high air temperature, the traditional internal combustion hot stove
