DESIGN AUTOMATION TOOL FOR COAL FEEDING SYSTEM IN THERMAL POWER PLANT

摘要

The invention relates to an optimization process for sequential locating of the components in a coal feeding system of utility boilers, wherein the coal feeding system comprises a downspout with a spacer connecting the bunker outlet to the feeder inlet, a needle gate mounted on the coal feeding line; and a bunker emptying chute configured corresponding to the height of the downspout including a seal head allowing maintenance of at least a quarter to one inch water column in the pulversier, the process comprising the steps of positioning a receiver at a location to obtain feedback signal captured by a plurality of sensor means disposed around the raw coal bunker; inputting associated functional parameters of the components of the system like bends, flanges, transitions in a processor with in-built logic; inputting the feedback signal parameters to the processor; automatic disposition of the system components for assembly based on the processed data outputted by the processor; and optionally redefining the locating data in case originally outputted data are not suitable for the system layout.
