A method and apparatus for on-line monitoring of solid-fuel/air rate of flows in a pipe as in a boiler or during gasification processes with high accuracy, high reliability, and a fast response are disclosed. The apparatus essentially comprises optical fiber vibration sensors, a spherical ejector rod, and a signal-emitting device installed in a housing, inside a pipe, to determine solid-fuel/air ratios and their rate of flow simultaneously. In terms of a master controller and a group of on-line controllers, monitoring the intake of granular carbonaceous material such as water vapor and air approaches the optimal operating status by regulating the temperature of the boiler or used in the gasification process, in accordance with the comparison of the data detected by current methods and optimal data.
The present invention is both a method and an apparatus for the purpose of solid-fuel/air rate of flow, which detects the solid-fuel/air ratio. In practice, will measure the coal slurry and air ratio. The present invention consists of a pipe to be measured, sensors, an on-line controller, and a compute that can effectively achieve adjustments for not only solid-fuel value, but also air and water vapors. The outcome achieved will be the monitoring of the optimal efficiency status.
