Claim Text:
1. A system for improving the reliability of a dry feed Integrated Gasification Combined Cycle pneumatic conveying system by using a determined real time solid flow rate of a solid-gas mixture, comprising: a plurality of sensors generating a plurality of measurement signals for obtaining at least three measured values of the real time solid flow rate; a data-fusion unit receiving the measured values and establishing a state-space model based on the measured values wherein said measured values comprise three blocks for respectively calculating the measured values, wherein a first measured value is calculated from the loss of solid weight per time unit; a second measured value is calculated based on solid volume percentage and solid velocity and a third measured value is calculated based on solid volume percentage and solid velocity and a differential pressure indicative of a pressure drop along a pipeline between two measuring points; an estimating unit estimating the state-space model to generate an estimated value of the real time solid flow rate; and improving the reliability of a dry feed Integrated Gasification Combined Cycle pneumatic conveying system by monitoring the calculated estimated real time solid flow rate and controlling the solid flow rate inputs.
