Introduction & Subsystem Blocks

Five pages of this website are dedicated to the decommissioning of the CP-JHC burner at Therbarton Laboratory, and recommissioning the burner at the new laser laboratory at the University of Adelaide University city campus. To develop the processes required to decommission and recommission the burner, the processes were broken down into four procedures. The four procedures are disassembly, cleaning and maintenance, transportation, and reassembly. These procedures are shown on the other four pages.

To further simplify these procedures, the procedures are sectioned into the four subsystems of the burner; the burner subsystem, the gas subsystem, the electrical subsystem, and the water subsystem. In each of these subsystems, there are numerous amounts of components varying in size and function. To keep the subsystem procedures organised and the components organised, the subsystems were theoretically simplified into 'blocks'. These blocks are just a collection of components considered similar in ways such as function or location. Due to large differences between the burner subsystems, the process of defining the blocks varies. This page is dedicated to defining the blocks of each subsystem.

Please note, if components from a subsystem were not included below and are not left attached to a listed component, write a note in the procedure submissions regarding the finding as well as any storage or procedural changes. 

Overview

The burner system was broken down into blocks based off of the top level assembly, i.e. the components location and connection. These blocks allow for the procedure to be completed in sections or stages. Furthermore, it allows for organisation and storage which reflects the procedures. 

Block Components

Overview

The gas system was divided into five blocks for the relocation procedures. The blocks of the gas system have been divided primarily by function, however, the location of components was considered to ensure all components and connections were accounted for. Each block of the gas system was primarily composed of the main subsystem and the relevant downstream connections. The five blocks of the gas system, GS01, GS02, GS03, GS04, and GS05, contain the components for the gas isolation valve train, gas booster system, flow meter board, main pressure vessel peripherals, and the exhaust peripherals subsystems respectively.

Block 1: Natural gas isolation valve train (GS01)

Block 2: Gas booster (GS02)

Block 3: Flow meter board (GS03)

Block 4: Main Pressure Vessel (GS04)

Block 5: Exhaust (GS05)

Block Components

Overview

To develop the electrical subsystem blocks, the subsystems of the electrical subsystems was first analysed. These subsystems are the burner management system (BMS) and the CCTV system. The CCTV system was considered simple enough to be one block. 

The BMS was divided up further to create another five blocks. The BMS has important function of monitoring and controlling factors including pressure, air flow and temperature both physically and digitally. The MATLAB control system monitors and controls the factors digitally. Therefore it is not a physical component, it is not required to be disassembled or reassembled. Hence, it was excluded from the block management. The physical BMS components include a thermal sensor loop, a low pressure sensor loop, a high pressure sensor loop, ignition controllers, and the main electrical board. 

Block Components

Overview

The water system was divided into five blocks primarily by function. The first block in the water system was the water manifold board and the components attached to the board (WS01). The four water loops were used to compose the remaining four blocks (WS02, WS03, WS04, WS05). The components included in the water system blocks did not include the water jackets as these are welded onto the burner system, and hence are managed with the burner system.
