Thermal power station - Wikipedia

The energy efficiency of a conventional thermal power station is defined as saleable energy produced as a percent of the heating value of the fuel consumed. A simple cycle gas turbine achieves energy conversion efficiencies from 20 to 35%. Typical coal-based power plants operating at steam pressures of 170 bar and 570 °C run at efficiency of 35 to 38%, with state-of-the-art fossil fuel plants

Steam-Atomizing and Air-Atomizing Burners

Steam-atomizing burners are simpler and less expensive than the air-atomizing type and are usually used for locomotive and small power plants. They handle commercial grade fuel oils Nos. 4, 5, and 6 and require a steam pressure varying from 75 to 150 psi. The oil pressure needs to be enough to carry oil to the burner tip, usually from 10 to 15 psi.

Boiler Efficiency and Combustion | Spirax Sarco

Pressure jet burners. A pressure jet burner is simply an orifice at the end of a pressurised tube. Typically the fuel oil pressure is in the range 7 to 15 bar. In the operating range, the substantial pressure drop created over the orifice when the fuel is discharged into the furnace results in atomisation of the fuel.

Steam Power Plant - an overview | ScienceDirect Topics

However, while reducing load, although throttle steam pressure remains unchanged, the throttle steam temperature is kept unaltered down to a load of about 60% in a typical pulverized coal-fired boiler. Below this load it is imperative to reduce the steam temperature for stability of boiler operation.

Steam Heating Process - Load Calculating

In general steam heating is used to. change a product or fluid temperature; maintain a product or fluid temperature; A benefit with steam is the large amount of heat energy that can be transferred. The energy released when steam condenses to water is in the range 2000 - 2250 kJ/kg (depending on the pressure) - compared to water with 80 - 120 kJ/kg (with temperature difference 20 - 30 o C).

Sliding Pressure - an overview | ScienceDirect Topics

Sliding pressure is when the pressure setpoint is adjusted online, usually for the turbine driven operation mode. In this case, the power plant can participate in the primary frequency control, at the expense of having to back-off from optimal operation and have MV2 partially open (e.g. 90 %) (Weissbach et al., 2006).The cycle efficiency decreases due to throttling losses in the steam valve
