Thermodynamics and Heat Engine: LESSON - 30 …

30.2. Economiser. Function: The function of the economiser is to extract some heat which is carried away by the flue gases up in the chimney or stack and utilize it for pre-heating the feed water supplied to the boiler. Location: It is placed in the path of the flue gases in between the exit from the boiler and entry into air preheater/chimney (Fig 30.1 and Fig 30.2).

Density Compensation for Steam Drum Level …

However, as the water heats up and pressure rises, the density of the water falls, and the density of the steam rises. Meanwhile the temperature of the water in the wet leg stays at the ambient temperature of the boiler house. Water boiling at 1310 PSIG is 580°F and is only 73% as dense as 100°F water.

When the higher boiler pressure pushes the steam out of the boiler into the distribution system, the steam will be at a higher temperature than the surrounding air. Hence heat flows from the steam thro the walls of pipe to the air causing some steam to condense.

Hartford Loop - MassEngineers.com

2018-7-29 · Here's how the Hartford Loop works. If a return line breaks, water can only back out of the boiler to the point where the wet return line connects into the equalizer. The Loop works like a siphon that runs out of water. The point where the Loop connects to the equalizer is higher than the boiler's crown sheet, and that's what provides the safety.
