Difference Between Impulse and Reaction Steam Turbine:
| Parameters | Impulse Turbine | Reaction Turbine |
| Efficiency | For the same flow rate & operating condition the efficiency of impulse turbine is very low | For same flow rate & operating condition the efficiency of the reaction turbine is high |
| Space Requirement | The size of impulse turbine is very less. | The footprint required for reaction turbine is high |
| Cost | The Cost of impulse turbine is much lower when compare to reaction turbine for same power rating. | Reaction turbine cost is much higher due to the critical shape of rotor |
| Application | Widely used in petrochemical and refineries. | Widely used in Power plants. |
| Staging | In the case of multistage impulse turbine, three type of compounding in impulse turbine. They are
1. Pressure Compounding
2. Velocity Compounding
3. Pressure – Velocity Compounding
| No compounding is available |
| Maintenance | Easy Maintenance | Not so easy when compare with impulse turbine |
