(1)根据多相燃烧理论对的移动式燃料层燃烧方案进行分析,指出该方案存在的问题,并提出改正方案,从而在理论上划定燃烧过程的不同区域,阐明各区域的特点;(2)同时根据多相燃烧热力理论分析和等对多相燃烧稳定状态的解释,指出他们在相对通风速度和固相质点尺寸对于燃烧过程放热与散热的影响上各自存在的偏面性,因而导致错误的结论。进而提出较全面的图解分析,说明了在不同运行条件下的燃烧状态,而且阐明不同固体燃料在相当的运行条件下各有其一定的最高温度与最大发热强度;(3)按照上述理论分析,对于移动燃料层的燃烧过程各特性区,提出相应的极限通风曲线,说明强化引燃和燃烧过程的关键;(4)最后对通用的强化办法予以简单评价。
(1) According to the theory of multi-phase combustion, the combustion scheme of mobile fuel layer is analyzed, the existing problems of this scheme are pointed out, and the correction scheme is put forward so as to theoretically demarcate the different regions of the combustion process and clarify the characteristics of each region; 2) At the same time, according to the theoretical analysis of multiphase combustion thermodynamics and the equal explanation for the steady state of multi-phase combustion, their respective partialities of relative ventilation velocity and solid particle size on the exothermic and heat dissipation of the combustion process are pointed out. Lead to the wrong conclusion. And then put forward a more comprehensive graphical analysis shows the combustion conditions in different operating conditions, and clarify different solid fuels in the corresponding operating conditions have their own maximum temperature and maximum heating intensity; (3) According to the above theoretical analysis, For the characteristic zones of the combustion process of the mobile fuel bed, the corresponding limit ventilation curves are proposed to show the key points of the enhanced pilot and combustion processes. (4) Finally, the general strengthening measures are briefly evaluated.
