Experimental studies on Gas—Particle Flows and Coal Combustion in New Generation Spouting—Cyclone COmbustor 总被引:1,自引:0,他引:1
Based on previous studies, an improved non-slagging spouting-cyclone combustor with two-stage combustion, organized in perpendicularly
vortexing flows, is developed for clean coal combustion applied in small-size industrial furnaces and domestic furnaces. The
isothermal model test and the combustion test give some encouraging results. In this study, further improvement of the geometrical
configuration was made, a visualization method and a LDA system were used to study the gas-particle flow behavior, and the
temperature and gas composition in combustion experiments were measured by using thermocouples and a COSA-6000-CD Portable
Stack Analyzer. Stronger recirculation in the spouting zone and the strongly swirling effect in the cyclone zone were obtained
in the improved combustor. The combustion temperature distribution is uniform. These results indicate that the improved geometrical
configuration of the combustor is favorable to the stabilization of coal flame and the intensification of coal combustion,
and it provides a basis for the practical application of this technique. 相似文献

Composite catalysts composed of different proportion of chemical reagents and steel industrial wastes were used as coal-burning additives. The effects of additives on combustion characteristics of anthracite coal and blended coal were studied by thermogravimetric analysis (TGA). The results showed that appropriate amount and proportion between chemical reagents and waste slag used as composite catalysts had good performances on the characteristics of coal combustion including ignition temperature, burnout temperature and burnout index, this will improve the coal combustion efficiency and also facilitate the comprehensive utilization of steel industrial waste slag. 相似文献
