low pressure high temperature steam boiler
Cleaver-Brooks | Reference Center | Boiler Basics | Steam or
Steam boilers are designed for low-pressure or high-pressure applications. Low-pressure boilers are limited to 15 psig design, and are typically used for heating applications. High-pressure boilers are typically used for process loads and can have an operating pressure of 16 to more than 1,000 psig.

What Causes High Pressure on Steam Boiler — Heating Help: The
A boiler is called a high-pressure boiler when it operates with a steam pressure above 80 bars. The high-pressure boilers are widely used for power generation in thermal power plants. In a high-pressure boiler, if the feed-water pressure increases, the saturation temperature of water rises and the latent heat of vaporization decreases.

Low Pressure Boiler Manufacturers | IQS Directory
Low Pressure Boilers. Low pressure boilers are tanks or vessels that facilitate the transfer of heat from its source to water or steam at pressures below 15 PSI. Though high temperatures within an enclosed space result in increased pressure, these boilers are able to keep pressure at or below the atmospheric pressure of ~14.7 PSI.

Lower Pressure Operation of Boiler than Designed – Implications
In constant pressure operation the boiler superheater outlet pressure is designed to be maintained constant from as low as 40% of the rated maximum continuous load. In sliding pressure boilers the superheater steam outlet pressure is slowly taken up at a particular ramping rate acceptable to both boiler and turbine designers.
