Embodiment Construction
[0036] The following examples help to understand the present invention, but do not limit the content of the present invention.
[0037] The designed control loop is configured by using Process Knowledge System (PKS) of Honeywell. The process targeted by the control system is a four-nozzle opposed gasifier, with a total of A, B, C, D four-way nozzle systems. In this embodiment, the inherent functional modules in the adopted PKS have the following categories:
[0038] 1. Each coal water slurry flow measurement module FI1203A(B, C, D)_1; each oxygen flow measurement module FI1303A(B, C, D)_1; each coal water slurry concentration measurement module FI1403A (B, C, D)_1; dry coal density measurement module FI1503A(B, C, D)_1; furnace temperature measurement module TI1304;
[0039] 2. Output module FV1203A(B, C, D)_1 for controlling the valve opening of each coal-water slurry flow; output module FV1303A(B, C, D)_1 for controlling the opening of each oxygen flow valve;
