A liquid fuel-fired power plant converts chemical energy from liquid fuels (like fuel oil or diesel) into electrical power through thermal processes. Oil-fired power plants can use different types of liquid fuels, but there are important distinctions in how these fuels are typically used:
Plant Types
Steam Cycle/Combined Cycle Power Plants
- Can burn both heavy fuel oil (HFO) and diesel
- HFO is preferred due to lower cost, despite requiring additional processing equipment
- Diesel is sometimes used as a backup or startup fuel
Diesel Engine Plants
- Primarily use diesel fuel or HFO in large reciprocating engines
- Large four-stroke diesel engines (5-20MW) typically run on HFO with 40-45% efficiency
- Small diesel generators (<1MW) typically use diesel fuel due to simpler handling requirements
Steam/Combined Cycle Oil-fired Power Plant
Components
- Fuel system
- Storage tanks for raw and processed fuel
- Fuel treatment systems for cleaning and heating
- Fuel pumps and control valves
- Filtration equipment for particulate removal
- Steam Generation
- Boiler with specialized liquid fuel burners
- Water walls for steam generation
- Superheater and reheater sections
- Economizer for feedwater heating
- Air and Gas Systems
- Forced draft fans for combustion air
- Induced draft fans for flue gas extraction
- Air preheaters
- Stack for exhaust gases
Plant Configurations
- Steam Cycle Plants
- Traditional configuration using boiler and steam turbine
- Efficiency ranges from 36-40%
- Suitable for base load operation
- Combined Cycle Plants
- Integrates gas turbines with steam generation
- Uses waste heat recovery steam generators
- Achieves higher efficiency up to 55-60%
- Greater operational flexibility
Dual-fuel Capability
Modern oil-fired power plants are often designed with dual-fuel capability, allowing them to switch between different liquid fuels depending on availability and economic considerations, though they typically don't burn multiple fuels simultaneously
