Abstract: Apparatus for controlling primary air flow and pulverized coal flow to a plurality of burners in a coal-fired boiler includes a plurality of coal dampers arranged to supply a mixture of air and pulverized coal to respective burners in the coal-fired boiler, each damper having a damper body and at least two orifice plates pivotally secured therein, the orifice plates movable between open and closed positions; a real time coal flow monitoring device operatively associated with each damper that is adapted to generate analog signals representing real time coal flow through its respective damper; and a programmable logic controller adapted to receive the analog signals and to adjust the orifice plates to balance the flow of air and pulverized coal to each of the plurality of burners.

Abstract: A method and computer program for automatically generating flowcharting instructions from an electronic text file of a source code. The steps include identifying the branch statements in the source code, determining the branch destinations for each of the identified branch statements, storing the destinations as destination records in a data structure, and identifying a statement type for each statement. Keys for determining that statement type may be a key work, phrase, punctuation marks or other symbols contained within each source code statement. The method is applied to source code statements written in any computer programming language. The instructions may then be imported into a drawing program where the flowchart may be drawn or viewed. The method may also be applied in reverse, automatically generating an electronic text file of a source code from a flowchart of a computer program.
