Volume II: description of system model of Westinghouse fluidized-bed gasifier, for the period February 28, 1983-March 18, 1983

Volume II describes the fluidized bed systems model which has been written in both BASIC and FORTRAN, along with its supporting codes. The systems model simulates the Westinghouse Fluidized Bed Coal Gasifier. A schematic of the gasifier is given. A total of 33 reference cases were obtained with the PSI/FLUBED program, described in Volume I. The operation of the gasifier at what we believe to be its normal design conditions is given in Table 1. This document describes our objectives in the development of the code and summarizes the overall mathematical approach. We describe the input and output characteristics of the G361/BAS code including: an overview of the logic flow, a definition of the input and output parameters. The input is of two forms, first a set of Taylor series expansion coefficients and the limits of the independent parameters are stored in a disk file G361/DAT. The second set of inputs is of the type that will be generated by the systems code in which the G361/BAS code operates. This data is also input manually by the analyst when operating the G361/BAS program to be operated in a stand-alone mode. Following the I.O section, we give a variable inventory. Heremore » we define all parameters which are used by the G361/BAS code. We have also provided an Operating Sequence section which describes the operation of the G361/BAS code. It is keyed by step number to the listing of the code which follows. Following this section we briefly describe the G361/CO checkout code and the G361/UPD code. This latter is used to develop or edit the input data file G361/DAT file.« less
