Gas-fired generating units have relevant requirements for engine rooms and gas pipelines, and must conform to the safe operation standards of gas-fired generating units. Jichai Generator Unit Manufacturing Enterprises are summarized as follows:
Requirements for Gas Generator Room
1. The electrical facilities in the engine room should be explosion-proof and the power supply must be cut off during electrical maintenance.
2. Emergency valves should be installed where gas pipelines enter the engine room. In case of emergency in the workshop, the gas source can be cut off quickly, and the valves should be close to the operating room.
3. The gas concentration alarm should be installed in the engine room, preferably at the diagonal line of the engine room. When the ambient concentration is within the range of explosion and poisoning concentration, forced ventilation must be carried out. After reducing the concentration, the unit can be started.
Requirements for Gas Pipeline of Gas Generator Set
1. Gas pipeline should adopt steel structure, pipe wall should not be too thin, joint should be sealed reliably. After gas pipeline connection is completed, gas detector or soap water should be used to detect pipeline leakage, especially at flanges, valves and other joints.
2. Valves should be inspected regularly. There should be no gas leakage, damage or other phenomena. There should be no accumulation around the valves that hinders the operation of the valves. Valves should be opened and closed regularly and maintained.
3. Rubber pipes on gas pipelines should be replaced regularly. It is forbidden to use expired aged rubber hose.
4. In the operation, maintenance and emergency repair of units and gas pipelines, the gas source must be reliably cut off so that the internal gas can be completely discharged. Gas supply to gas facilities shall not be restored until the cause of the accident is ascertained and necessary safety measures are taken. Explosion-proof measures or explosion-proof tools should be taken during maintenance and overhaul. Striking with iron and other tools is strictly prohibited.
5. After cutting off the gas source, the leak should be repaired immediately. When combustion occurs in the leak, measures should be taken to control the fire before cutting off the gas source.
