What is Tdbfp?

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.

How many megawatts does a steam turbine produce?

The First Steam Turbine Now, steam turbine generators can produce over 1,000 MW of energy in large-scale power plants. While generation capacity has increased immensely since Parsons, the design has remained the same.

What is LP and HP of a turbine?

HP and LP refer to ‘High-Pressure’ and ‘Low-Pressure’ shafts, and speeds. The pressures are “relative” pressures, one turbine operating at a higher pressure than the other, which is called the “low pressure” turbine (shaft). Some GE-design gas turbines have multiple shafts that spin at independent speeds.

What is CRH in power plant?

Cold reheat P&I diagram. CRH steam starts its journey from the outlet HPT and/or HP bypass (HPBP) station outlet with the aim to reach the reheater inlet at the boiler. Depending on the boiler turbine configuration, there may be a single or double CRH line.

Which pump is used in boiler?

A boiler feedwater pump is a specific type of pump used to pump feedwater into a steam boiler. The water may be freshly supplied or returning condensate produced as a result of the condensation of the steam produced by the boiler.

What is BFP power plant?

In a thermal power plant, the boiler feed pump (BFP) is one of the critical auxiliary machines that are equivalent to the heart of the plant.

Why LP turbine is double-flow?

For turbines of large output, it is normal to have several double-flow low pressure (LP) cylinders operating in parallel. The second benefit is that the double-flow cylinder effectively reduces to zero the axial thrust caused by the steam forces on the moving blading.

Why do we reheat steam?

Why Reheating of steam is used? Explanation: Work output = work done by turbine – work done by compressor. Explanation: Since work output increases the steam rate decreases. Explanation: Efficiency = work output / heat supplied, heat supplied is less in this condition only.

What is hot reheat steam?

The steam produced by the Final Reheater is then called Hot Reheat steam. Hot Reheat steam then goes to the low-pressure steam turbine, so that the heat energy contained in it is converted into mechanical energy of the turbine shaft rotation.
