福建省晋江公路分局试制了一个“0.12m~3超小型煤粉旋风炉”。通过两年来的使用,实践表明:旋风炉喷火能有效地替代石油在烘干设备上的应用,经济效益是显著的。节约了石油资源;解决了普通燃煤炉热强度低、燃烧质量差的缺点,特别是炉体体积庞大难以搬迁的困难,提高了拌和机械的整体机动性。一、燃烧原理煤粉旋风燃烧是一种较年轻的、先进的燃烧技术。其燃烧过程主要是在一个具有圆形截面的燃烧室中进行的。依靠正切向引进炉内的高速旋转二次风射流,强化割向引进的一次风粉射流,人为地组织起一种热力强
Fujian Jinjiang Highway Branch trial of a “0.12m ~ 3 ultra-small coal cyclone furnace.” Through the use of two years, practice shows that cyclone furnace spray can effectively replace the application of oil in drying equipment, economic benefits are significant. Saving oil resources; solves the shortcomings of low heat intensity and poor combustion quality of ordinary coal-fired furnaces, and in particular, difficulties in relocating large-sized furnaces and increasing the overall mobility of a blending machine. First, the principle of combustion Pulverized coal combustion is a relatively young, advanced combustion technology. The combustion process is mainly carried out in a combustion chamber with a circular cross-section. Rely on the introduction of tangential to the furnace high-speed rotating secondary air jet, strengthen the cut to introduce a wind powder jet, artificially organize a strong heat
