Method and apparatus for adjusting combustion in furnace
专利汇可以提供Method and apparatus for adjusting combustion in furnace专利检索，专利查询，专利分析的服务。并且PURPOSE: To maintain a uniform temperature in a combustion zone in a rotary kiln by a method wherein whole ash contents in coal are measured by data, and a process computer changes a flow of the coal in either case of furnace temperature being lower or higher than a predetermined temperature.
CONSTITUTION: A pulverized-coal supplying apparatus 1 for supplying pulverized coal with weighed weight to a multi-channels burner 9 is driven by a variable speed driving apparatus 2. When a sample is sequentially taken out by an automatic sampling apparatus 3, the sample is collected into a small hopper and mixed and fed to a sample-preparation unit apparatus 4. The unit apparatus 4 supplies briquets obtained by mixing the pulverized coal with a binder and compacting the mixture to an online analysis apparatus unit 6. Information in relation to percents of contents of silica, alumina, and other data are fed to a process computer 7. The process computer 7 adjusts the variable speed driving apparatus 2 to decrease coal supply to the burner 9 when a surface temperature at this time is too high. On the other hand, when the furnace temperature lowers, fuel such as fuel oil or fuel gas is fed to the burner 9 via a flowmeter 5 from a storage tank 8.
