What is Tdbfp power plant?
TDBFP stands for TURBINE DRIVEN BOILER FEED PUMP. These kind of pumps are generally designed for large capacities. Boiler feed pump is coupled with a smaller turbine and these turbines are steam driven.
What are the electrical parameters measured in thermal power plants?
Electrical measurements – current, voltage, power, frequency, power – factor etc. – non electrical parameters – flow of feed water, fuel, air and steam with correction factor for temperature – steam pressure and steam temperature – drum level measurement – radiation detector – smoke density measurement – dust monitor.
How do you calculate thermal efficiency of a power plant?
To express the efficiency of a generator or power plant as a percentage, divide the equivalent Btu content of a kWh of electricity (3,412 Btu) by the heat rate. For example, if the heat rate is 10,500 Btu, the efficiency is 33\%. If the heat rate is 7,500 Btu, the efficiency is 45\%.
What is a turbine driven boiler feed pump?
In general, the boiler feed pump turbine uses both steam from the boiler and the main turbine to drive the mechanical shaft connected to the boiler feed pump. This arrangement has proven highly successful in efficiently applying the steam’s thermal energy throughout the plant.
What is the use of boiler feed pump?
Boiler feed pumps are also referred to as feed pumps (see Reactor pump) and designed as multistage radial flow pumps. (Also see Multistage pump.) They serve to feed a steam generator such as a boiler or a nuclear reactor with a quantity of feed water corresponding to the quantity of steam emitted.
What is thermal efficiency and overall efficiency?
Thermal efficiency relates to processes where the input is thermal energy as in a fired power plant, a internal combustion engine or solar energy systems. Overall efficiency looks at entire systems from the initial input to the final output. The input does not necessarily have to be thermal in nature.
What is the overall efficiency of the thermal plant in India?
Thermal power plants, backbone of the electricity systems converting heat energy into electrical energy records efficiency between 30 & 50\%. Consequently, the balance heat gets dissipated into the atmosphere.
How electricity is produced in a thermal power station?
Steam power generation Fuels such as heavy oil, LNG (liquefied natural gas) and coal are burned inside a boiler to generate steam at high temperature and high pressure. This steam is used to rotate the impeller of the steam turbine. This drives the power generators connected to the turbine that generate electricity.
What are primary measurements of power plant?
Pressure and temperature are two of the most widely measured parameters in a power plant. Ensuring that processes remain within set temperatures and pressures can have a major impact on optimizing efficiency.
How do you calculate plant efficiency?
The same quantitative analysis is used when calculating the thermal efficiency of a power plant: Measure the amount of electricity produced (less any losses) and then divide by the amount of fuel consumed to arrive at the plant’s thermal efficiency.
What is tdbfp in a boiler?
TDBFP (turbine driven boiler feed pump)For feeding water in boiler drum. Before the unit sync instead of TDBFP; MDBFP (motor driven boiler feed pump) used which is highly power consumed about 11 MW for 600 MW unit.so to save auxilary power consumption TDBFP use.
What is a tdbfp pump?
TDBFP stands for TURBINE DRIVEN BOILER FEED PUMP. These kind of pumps are generally designed for large capacities. Boiler feed pump is coupled with a smaller turbine and these turbines are steam driven. Steam is derived from different sources (such as extraction or aux. steam).
What is the difference between tdbfp and mdbfp?
Before the unit sync instead of TDBFP; MDBFP (motor driven boiler feed pump) used which is highly power consumed about 11 MW for 600 MW unit.so to save auxilary power consumption TDBFP use. To run the TDBFP we use exhaust steam from the turbine so there is no extra power consumtion ( motor not require).
What is the advantage of tdbfp over a motor driven BFP?
The main advantage of having TDBFP in service is having the Motor Driven BFP in standby mode which can be used during emergencies. its serves same as motor driven boiler feed pump the only difference is, in TDBFP as name suggest it is driven by the extraction steam from turbine
