    3. Power and heat supply for petrochemical, oil refining, and chemical plants
    4. Low calorific value (LCV) gas power generation for steel mills
    5. Peak-shaving power plant / standby power
    6. Isolated grid (island mode) operation and independent power stations for remote areas
  5. Unit / Machine Advantages
    1. Proven and reliable: over 45 years of global service, with more than 1,200 units installed and cumulative operation exceeding 100 million hours; availability of 98%+.
    2. Maintenance-friendly: modular combustion system, well-defined inspection intervals, common/spare parts interchangeability, and high level of localization / domestic manufacturing.
    3. Fast start-up and stable load capability: well suited for peak shaving, standby power, and island-mode operation; supports rapid start-stop cycles.
    4. Strong CHP / cogeneration adaptability: stable exhaust parameters and high waste heat recovery efficiency, making it ideal for distributed energy and district / campus heating.
    5. Significant upgrade potential: can be retrofitted with dry low NOx (DLN) combustion, efficiency improvement packages, life-extension services, and hydrogen blending / fuel-flexibility modifications.
