Important one liner (Steam Power Station)
- A steam power station converts heat energy into electrical energy using the Rankine cycle.
- Coal combustion in the boiler releases thermal energy to generate high-pressure steam.
- The economizer preheats feed water by recovering heat from flue gases before entering the boiler.
- Superheaters increase steam temperature beyond saturation for higher turbine efficiency.
- High-pressure steam expands through turbine blades to produce mechanical rotation.
- The condenser recovers exhaust steam by condensing it back into water for reuse.
- Feed pumps pressurize water to ensure continuous circulation through the boiler.
- Deaerators remove dissolved gases from feed water to prevent corrosion in the system.
- Air preheaters transfer heat from flue gases to incoming combustion air to improve efficiency.
- Draft fans regulate furnace air flow to maintain steady combustion conditions in the boiler.
- Electrostatic precipitators capture ash and particulate matter from flue gases to reduce emissions.
- Cooling towers dissipate waste heat from the condenser into the atmosphere via evaporation.
- Reheaters boost steam temperature between turbine stages to improve overall cycle performance.
- Boiler drums separate saturated steam from water before the superheater stage.
- Ash handling systems transport and store solid waste byproducts from coal combustion.
- Chemical treatment of feed water prevents scale and corrosion inside boiler tubes.
- Control systems monitor pressure, temperature, and flow parameters for safe operation.
- Transformer stations step up generator voltage for efficient transmission over high-voltage lines.
- Grid synchronization ensures stable connection of generated power to the electrical network.
- Efficiency improvements focus on reducing auxiliary power consumption and heat losses.
