| 1 | Influence of Coal Nature and Structure on Ash Size Formation Characteristic and Related Pollutant Emissions During CFB Combustion显示文摘The size distribution of coal particles in a Circulating Fluidized Bed (CFB) boiler plays a crucial role in the complicated combustion, heat exchange and pollutant emissions in such a plat. Therefore, it is fundamental to study the different factors having influence on the size distribution of coal particles. Above all, the coal itself and in particular, the coal combination phenomenon is a very influent factor. In the frame of this work, the coal nature (elementary composition) and coal internal structure (mineral components) are studied in detail. At this intermediary stage, experiments on three typical Chinese coals on a l.5 MWt CFBC pilot plant have been made. Some primary fragmentation tests have also been made in a small lab scale fluidized bed reactor. The results from the hot pilot test show i) the variation of coal ash distributions and other CFB performance data due to the cyclone and the coal characteristics and ii) the variation of desulfurization efficiency with limestone. Whereas the bench scale primary fragmentation test, likely linked to the caking propriety of a coal, does not seem to change considerably the char size distribution. | Min QIAN Arnaud BOELLE Philippe JAUD ( Electricite de France Division R&D, 6 quai Watier B.P.49 78401 Chatou, France ) Yongjie NA Qinggang LU Shaolin BAO ding CUI Weihong JIAO Huanming ZHAO (Institute of Engineering Thermophysics, Chinese Academ | 2000 | Journal of Thermal Science2000，9，3： | 2 |

| 20 | Three Dimensional Modeling of Pulverized Coal Combustion in a 600 MW Corner Fired Boiler显示文摘The three-dimensional code ESTET developed at the LNH has been used to predict the reactive flow in a 600 MW coal fired boiler. Assuming a no-slip condition between the gas and the coal, the equations for a gas-particle mixture can be written. The pulverized coal particle size distribution is represented by a discrete number of particle size groups determined by the measured fineness distribution. The combustion models taking into account the pyrolysis of the particle and the heterogeneous combustion of char have been validated using intensive measurements performed on the 600 MW utility boiler. Heat fluxes were measured along the walls of the furnace and satisfactory agreement between computation and measurements has been achieved in terms of maximum flux location and heat flux intensity. Local measurements of velocities using LDV probe, gas temperature and gas species concentrations were performed in the vicinity of one burner and compared with the computed variables. Again we have observed a good agreement between the computations and the measurements in terms of jet penetration, temperature distribution, oxygen concentration and ash content. | Sandro Dal-Secco (Department MFTT, E.D.F., 6 Quai Watier, 78400 Chatou, France) | 2000 | Journal of Thermal Science2000，9，4： | 0 |
