some common names of low and high pressure boiler

KEY COMPONENTS OF BOILERS | Boilers Guide

Common burner firing sequences include on/off, high/low/off and modulating. Boiler safety controls include high pressure and temperature, high and low gas/oil pressure, and high and low water level and flame safeguard controls. These controls are considered safeties or limits that break the electrical circuit to prevent firing of the boiler.

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 (72,000 kPa or 1290 psi) but, at pressures above this, it is more usual to speak of a steam generator.

Steam heating systems run with even lower pressure, typically at less than 1 psi in all. However, these types of boilers are less common (especially in newer homes), and operate using a different system.
