High Pressure Steam Industrial Boiler Feed Water Pump

If the boiler steam pressure reaches 3 psi, the burner will drop to low fire and stay there until the boiler pressure drops. If the pressure drops to 1 psi, the burner will drive to high fire until it reaches 3 psi.

Steam Boiler Statistics - Feed The Beast Wiki

The pressure penalty makes HP boilers consume more fuel per steam than LP boilers, thus HP boilers are less fuel-efficient. This is compensated by the increased space and resource (iron) efficiency of HP boilers per unit power. A small LP boiler consumes 10.8 HU/cycle at full heat, while a small HP boiler consumes 12.8 HU/cycle (19% more).

Steam and Condensate - A basic overview of a steam system

The steam hits the plates, and any drops of moisture in the steam collect on them, before draining from the bottom of the separator. Steam passes from the boiler into the steam mains. Initially the pipework is cold and heat is transferred to it from the steam.

Multiple steam boiler piping concept — Heating Help: The Wall

The flow of steam in the boiler is much different than typical boilers. After it moves through the port connectors, it takes a turn down the very wide end section which probably kills velocity allowing water to drop out and then hits an inclined plane which probably further drys out the steam and then reaches the exit tapping.

Common Steam Boiler Problems & How to Troubleshoot Repairs

When new water enters the tank, though heated, it’s still colder than the boiler water. This temperature difference creates a  reduction in steam production until the fresh water warms up. Lower production of steam can drop the pressure temporarily. A continuous feedwater system may help alleviate this problem.

Boiler (power generation) - Wikipedia

A boiler or steam generator is a device used to create steam by applying heat energy to water.Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure (7–2,000 kPa or 1–290 psi) but, at pressures above this, it is more usual to speak of a steam generator.
