Plant Components:

Fuel Supply System:

• Fuel storage tanks (adequate capacity for HFO storage)
• HFO pre-heating system (to maintain the appropriate viscosity for engine combustion)
• Fuel filtration and supply system for ensuring clean fuel enters the engine

Exhaust Gas System:

• High-efficiency exhaust gas treatment systems to reduce emissions (e.g., SCR for NOx, Electrostatic Precipitators, or Wet Scrubbers for particulate matter)
• Chimneys and stacks to safely vent exhaust gases
• Economizer for heat recovery from exhaust gases to improve plant efficiency

Cooling System:

• Closed-loop cooling system or direct air-cooling system
• Heat exchangers for maintaining engine temperature and efficient operation
• Cooling towers if needed for water-cooled engines

Generator System:

• Synchronous generators rated for 11-15 kV and 50/60 Hz output
• Generator protection and control systems
• Voltage regulators to ensure stable power output

Control and Protection Systems:

• Advanced SCADA (Supervisory Control and Data Acquisition) system for monitoring and control
• PLC (Programmable Logic Controllers) for automated engine control and plant operations
• Protection devices for engine and generator systems (overcurrent, under/over voltage, overspeed, etc.)
• Remote monitoring capabilities for operational troubleshooting and maintenance

Electrical Systems:

• Power transformers (from 11 kV/13.8 kV to grid voltage)
• Switchgear and protection relays
• Power factor correction systems (if required)

Plant Efficiency & Operations:

• Thermal Efficiency: Typically 40-45% depending on engine configuration and heat recovery systems (if any).
• Operational Hours: Engine-based plants typically run at high availability (up to 90-95% depending on maintenance schedules).
• Maintenance: Routine maintenance intervals of approximately 1,500 to 2,000 hours.
  • Major Overhaul: Every 15,000 – 20,000 operational hours.

Environmental Compliance:

• Emissions Control: Designed to meet the local regulatory standards for emissions. This includes:
  • NOx Reduction: Selective Catalytic Reduction (SCR) or similar methods
  • Particulate Matter Control: Electrostatic Precipitators or Wet Scrubbers
  • CO2 Emissions: CO2 emissions are a direct result of HFO combustion, but emissions are managed within the limits of local environmental standards.

Auxiliary Systems:

• Lubrication System: Automatic lubrication of engine components to minimize wear and tear.
• Water Treatment System: For cooling and steam generation if required.
• Fire Safety: Fire suppression systems in place for fuel storage, engine rooms, and other critical areas.

Plant Configuration:

• Grid Connection: Designed to connect with the local electrical grid or operate in an isolated mode (off-grid) if necessary.
• Load Following: The plant can provide base-load or peak-load capacity based on the needs of the grid or private consumers.

Dimensions and Weight:

• Footprint: Varies depending on engine configuration and additional equipment.
  • Typical plants of this size can occupy approximately 1-2 hectares (10,000 - 20,000 m²).
• Weight: Typically between 500-700 tons, depending on the number of engines, fuel system, and auxiliary equipment.

Operational Considerations:

• Startup Time: Typically, the plant can be started within 10-30 minutes, depending on the engine type and pre-start procedures.
• Load Acceptance: The engines can accept full load within minutes after startup.
• Operational Flexibility: Able to provide both continuous (base-load) and intermittent (peak-load) power based on demand.
