Advantages of Using Natural Gas Generator in Factories

Every landfill gas generator uses gas from landfill sites instead of natural gas. This means the generator’s maintenance won't be the same as maintenance for standard generators. Since landfill gas contains impurities, including moisture, hydrogen sulfide, and siloxanes, these impurities can cause internal issues and lead to generator parts wearing out quickly or breaking down. Therefore, the generators' maintenance will need to focus on the impurities first for the system to continue working well.

Pre-Operation Maintenance Checks  

To avoid any surprises, it’s best to do a full check before starting a landfill gas generator. Start with the gas supply system. Check the gas filters to see if they’re clogged with impurities. Clogged filters will slow down gas flow and the generator’s efficiency will be affected. After that, check the fuel lines for leaks. Even small gas leaks are expensive and dangerous. Then check the oil level and the oil’s quality. Good oil prevents the moving parts of the engine from jamming. Low or dirty oil will cause the engine to overheat and become damaged. Finally, check the ignition system. Defective or weak ignition systems will cause starting problems or a rough running generator.

Regular Maintenance Tasks for Long Term Performance

To ensure your landfill gas generators operate effectively for an extended period, regular maintenance tasks must be performed. One of the most fundamental tasks of maintenance is performing regular changes of gas, oil, and air filters. The maintenance frequency is determined by the usage of the generator and the quality of gas at the landfill. If the gas contains many impurities, filters will have to be changed every few weeks. Cleaning the Engine components is another important task. The gas impurities may cause the carburetor and the spark plugs to become dirty. Cleaning these parts of the engine will help it burn fuel more efficiently. Fuel efficiency is important, but do not neglect the cooling system. Always check if the coolant level is okay and if there are any leaks. The engine cooling system will prevent the engine overheating, which is important for the engine efficient operation and the engine life span.

Common Issues in Gas Generators for Landfills

Gas used in landfill generators can present generators with some issues. One of these issues is corrosion. The hydrogen sulfide in the gas will react with metal components of the generator and will cause the metal to rust. The use of corrosion resistant gas contact components will help mitigate this issue. Chemical additions to the gas to lower hydrogen sulfide concentration will also help. The engine can also suffer from issues due to the gas generator being landfill impurities. These impurities will cause the engine’s internal valves and pistons to become caked with carbon and therefore reduce engine power and performance. The engine will need to be decarbonized regularly to keep this from occurring. This can be achieved with engine cleaning products through a professional or by your own means. An unevenly running generator will also suffer from performance issues due to a fuel injector that has become clogged. This issue can be resolved by cleaning or replacing the fuel injector.

Testing and Verifying Work Done After Maintenance

After Maintenance done on a Landfill Gas generator Testing and Verifying the Work is Done Right is Critical. First, HRSG Generators Should be Started and Run For a bit. Ensure the Generator Starts and Runs Without Hiccups. Listen For Testing Noises as well, specifically if the Generator is Knocking or Grinding, those could Engineer an Issue With the Inline Engine. After, Monitor the Generator Consumption and Output, Gas and Voltage as well as Current, and Ensure all Indices Are Within the Range. If the Engine is Spending an Abnormally Higher Amount of Gas the Generator is likely Leaking or There is Gas Issue on the Fuel System. Finally, do an Inspection again on all Working Parts rest.
