@world.of.engineer97: #⚙️ SUPERCRITICAL BOILER POWER PLANT | Understanding Advanced Steam Generation How does a supercritical boiler improve the efficiency of a thermal power plant? The answer lies in operating at steam conditions above the critical pressure of water. In a supercritical boiler, the working fluid passes continuously through the once-through pressure-part system. Unlike a conventional subcritical boiler, the main flow does not rely on a steam drum to separate boiling water and steam. 🔥 Key Engineering Processes: 1️⃣ Coal Pulverization — Raw coal is ground into fine particles for efficient combustion. 2️⃣ Combustion & Heat Transfer — Thermal energy from the furnace is absorbed by the water-wall tubes. 3️⃣ Supercritical Operation — Water is heated at pressure above 22.064 MPa, the critical pressure of water. 4️⃣ Superheater — Additional heat produces high-temperature main steam for turbine expansion. 5️⃣ Steam Turbine — Steam energy is converted into mechanical rotation and then electrical power. 6️⃣ Reheat & Condensation — Reheating supports efficient expansion, while the condenser returns exhaust steam to the feedwater cycle. 💡 Mechanical Engineering Perspective Supercritical boiler technology requires strong attention to pressure-part integrity, high-temperature materials, thermal expansion, tube-wall temperature, feedwater reliability, welding quality, and operational safety. The performance of a power plant depends not only on boiler efficiency, but also on the reliability and coordination of its entire steam-water cycle.
