5. Efisiensi boiler menggambarkan jumlah energi yang akan digunakan dan zat buang / limbah yang diproduksi oleh boiler

6. Potensi heat loss atau energy loss yang terjadi pada boiler

7. Beragam metode kalkulasi efisiensi boiler

8. Efisiensi boiler dengan Direct Method Qw = Energi pada steam stream (output) Qc = Energi dari fuel (input)

9. Improving the combustion process : This can involve optimizing the air-to-fuel ratio, reducing excess air, and improving the mixing of fuel and air to ensure more complete combustion and reduce losses due to incomplete combustion. Upgrading the steam cycle : This can involve increasing the steam pressure and temperature, improving the heat transfer surfaces in the boiler and steam turbine, and using advanced materials to reduce heat losses. Waste heat recovery : This involves capturing waste heat from the power plant and using it for other purposes, such as heating buildings or producing steam for industrial processes. Co-generation : This involves using the waste heat from power generation to produce additional electricity or useful heat, such as for heating or cooling buildings. Carbon capture and storage : This involves capturing the carbon dioxide emissions from the power plant and storing them underground or using them for other purposes. Advanced control systems : This involves using advanced control strategies to optimize the operation of the power plant and reduce losses due to inefficiencies or operating at suboptimal conditions How to increase the efficiency?

11. Batu bara dihancurkan hingga halus Batubara diinjeksi ke furnace/combustion chamber : Energi kalor dari pembakaran memanaskan air di dalam tube : Air berubah menjadi gas dengan tekanan tinggi menggerakkan turbin Water Tube Boiler Tube yang diisi air untuk menghasilkan uap

12. Gas metana dibakar dan dialirkan ke tube Energi kalor dari pembakaran memanaskan air di steam dome Air berubah menjadi gas dengan tekanan tinggi menggerakkan turbin Fire Tube Boiler

13. Water Tube Boiler Fire Tube Boiler Tube content Water Hot gas / Exhaust Tube surrounding Hot gas Water Pressure and temperature Higher Lower Efficiency Higher Lower Cost Higher Lower Operating complexity More Complex Simpler Perbandingan

14. Maintenance and Hazard The importance of boiler maintenance and the possible hazard on boiler 04

16. The NTPC power plant in Unchahar, Uttar Pradesh, experienced a catastrophic failure in one of its coal-fired boilers, resulting in a massive explosion. The explosion caused a large fire and resulted in the deaths of 45 people and injuring more than 100 others caused by a build-up of pressure inside the boiler due to a blockage in a duct that carries coal dust. The pressure caused the boiler to rupture, leading to the explosion.
