Power plant and calculation site basically includes the detailed study of power plant operation and maintenance, its related all calculations and thumb rules. It also involves detailed troubleshooting guides for operation and maintenance of power plant system/equipments like Boiler, fans, compressors, belt conveyors, ash handling system, ESP, steam turbine, cooling tower, heat exchangers, steam ejectors, condensers WTP. etc.
Heat rate, efficiency
Note: The calculator provides preliminary equipment
capacity estimates based on the specified engineering thumb rules.
Actual equipment selection should be verified against the turbine,
plant design requirements and OEM recommendations.
Note:
The calculator uses the IAPWS-IF97 formulation for
superheated steam properties.
Enthalpy is calculated from pressure and temperature,
rather than using a constant specific heat approximation.
The enthalpy of evaporation is calculated from the
difference between saturated-vapor and saturated-liquid
enthalpies at the entered pressure.
For critical engineering/design calculations, verify
results against certified steam tables.
This calculator is based on centrifugal fan affinity laws. Select the unknown value and enter all remaining required values. The calculator will automatically calculate the selected unknown value.
Cogen turbine heat rate is the amount of heat energy required by a cogeneration system to generate one unit of electrical energy. It is generally expressed in kcal/kWh or kJ/kWh. A lower heat rate indicates better energy efficiency, meaning less heat energy is required to generate each unit of electricity.
What are the Inputs required for the Calculation of Cogen Turbine Heat rate calculation?
Turbine inlet steam flow in TPH
Turbine inlet steam pressure and temperature
Bleed steam flow
Bleed steam pressure and temperature
Extraction steam flow
Extraction steam pressure and Temperature
Exhaust steam flow
Exhaust steam pressure
Co-gen-THR =((Turbine inlet steam flow X its Enthalpy)-(Process steam flow X Enthalpy Exhaust steam flow X Enthalpy)) / Power generation
Steam Turbine Co-generation Heat Rate Calculator
Steam Turbine Co-generation Heat Rate Calculator
Calculate Turbine Heat Rate using Inlet, Extraction / Bleed and Exhaust Steam Conditions
Important:
Exhaust enthalpy is considered as saturated liquid enthalpy (hf)
based on exhaust pressure. Exhaust temperature is not used for
exhaust enthalpy calculation.
Note:
Steam enthalpy is estimated internally from pressure and temperature
using an engineering approximation. This is suitable for indicative
online calculations. For guaranteed turbine heat-rate calculations,
validated steam tables or IAPWS-IF97 properties should be used.
Online water leakage arresters are specialized sealing and leak-stopping compounds or devices used to stop water leakage in pipelines, valves, flanges, tanks, condensers, cooling water systems, and hydro/thermal power plant equipment without shutting down the system.
Advantages of Online Leakage Arresting
No plant shutdown
Reduces production loss
Fast repair
Improves safety
Cost-effective maintenance
Prevents further damage
Following are the some sealants and tapes which are commonly used for Online water leakage arresting.
Power plants use different jointing and sealing compounds depending on temperature, pressure, steam service, oil exposure, chemicals, and maintenance requirements. Below are some of the most commonly used jointing and sealing compounds in thermal power plants, CHP plants, and process industries.
