Numerical Analysis of the Factors about Combustion Stability on Boiler
Abstract: Through the research
of the coal pulverized catches fire and steadily combustion mechanism, the
numerical simulation of the 300MW tangentially pulverized coal fired boiler by
Coal-fire software, and combine the operating data of the boiler, the
corresponding relation between the result of numerical simulation and
combustion stability have been established. The result indicates that the
higher volatile matter, lower content of ash and moisture of the coal, it helps
the coal pulverized air current to catch fire. More fineness coal pulverized is
favorable to catch fire. When boiler load reduced, it will influence the
characteristic"lighted by itself" of the tangentially pulverized coal
fired boiler, and it will cause combustion unstably.
