in tpp how steam pr. decreases from steam drum to main steam line..

Answer / Pooja

In a Thermal Power Plant (TPP), the pressure of steam decreases as it travels from the steam drum to the main steam line due to various reasons:

1. Expansion: As steam expands during the movement, its pressure drops. This happens because the volume occupied by steam increases while the mass remains constant.

2. Friction: The friction between the steam and the pipe walls causes a loss of energy in the form of heat. This leads to a decrease in steam pressure.

3. Heat loss: If there are any leaks or cracks in the pipes, it can cause heat loss and result in reduced steam pressure.
