Boiler efficiency
Boiler: Steam boiler is basically a closed vessel in which water is heated until the water is converted into steam at the required pressure. This is the most basic definition of a boiler.
Working principle of boiler
The basic working principle of boiler is very simple and easy to understand. A boiler is essentially a closed vessel inside which water is stored. The fuel (usually coal) is burned in a furnace and hot gases are produced. These hot gases come in contact with water where the heat of these hot gases is transferred to water and as a result steam is generated in the boiler. Then this steam is conveyed to the turbine of the thermal power plant.
Steam Boiler Efficiency (50 TPH)
| Steam Quantity | 28412.9 |
| Feed Water Quantity | 29265.3 |
| Steam temperature | 470 |
| Enthalpy of steam | 799.689 |
| Feed water temperature | 127 |
| Enthalpy of feed water | 128 |
| Rice husk quantity | 5861.04 |
| Calorific value | 3200 |
| Pith Quantity | 1591 |
| Calorific value | 2200 |
| Boiler Efficiency = | {(Steam Qty × Enthalpy of steam)-(Feed water Qty × Enthalpy of water)} / |
| {(Rice husk × calorific value)+(Pith × calorific value)} |
| Boiler Efficiency= | ((28412.9*799.689) – (29265.3*128)) / ((5861.04*3200)+(1591*2200) |
| Ƞ boiler = | 0.852621 |
| Boiler Efficiency | 85.26 % |
