The engine room of equipped gas-fired generating units should be spacious, bright and far from the open fire area, and ventilation equipment such as ventilation fans should be equipped to ensure excellent ventilation environment in the engine room. The machine room should be equipped with lightning protection equipment to ensure the safety of the machine room in thunderstorm days. In addition, the engine room should also be equipped with gas leakage alarm equipment, the lighting of indoor equipment, circuit switches and other electrical equipment requirements and equipment corresponding explosion-proof measures and fire extinguishers and fire-fighting equipment.
Gas valves (stainless steel ball valves), U-type drain valves and anti-tempering equipment are necessary for the external pipelines of gas pipelines of gas generating units. Welding slag should be sorted out in time after welding of gas pipelines is completed. For the diameter of gas pipeline, please refer to the operation and maintenance instructions of gas generator set.
It is necessary to desulfurize, dehydrate and dedust the gas required for gas input by gas generating units. The sulfur content in the gas entering the generating units should be less than or equal to 0.2 mg/m3. The gas generating units'intake pressure should be between 2 and 100 Kpa, and the calorific value of methane in the gas should be more than 5500 kcal/m3, and the calorific value of natural gas should be more than 8000 kcal/m3.
It is necessary to use softening water or antifreeze for cooling water of gas-fired generating units.
For the requirements and specifications of cables, batteries and batteries for external output load, please refer to the requirements for accessories of gas-fired generating units in the statement of matching operation and maintenance of gas-fired generating units.
The engine oil and coolant should be checked before starting a gas-fired generating unit.
If the gas-fired generator is not successfully started within 10 seconds, it should be started again after 2 minutes. If the gas-fired generator is not successfully started three times in a row, it is necessary to check the gas-fired generator and find out the reasons.
After the successful start-up of the gas-fired generator unit, the engine should be idled for 5-10 minutes. Before the gas-fired generator unit stops, idle operation for 5-10 minutes is also required.
When users first use new gas-fired generating units, they should carry out 60-hour commissioning according to the regulations. And it should be slowly raised to high speed after the cold car starts the gas generator set. It is strictly forbidden to suddenly increase the speed and to rotate over the idle speed for a long time.
After shutdown, if the ambient temperature is lower than + 5 C, the water in the water tank, gas generating unit and oil cooler of gas generating unit should be discharged.
It is strictly forbidden for gas-fired generating units to be exposed to unavailable air
