If a boiler has reached 220°F, a sudden drop in pressure could cause the tank to burst. Overheating also is the main cause of leaking. When the water temperature in the boiler becomes too high, it increases the water pressure throughout the system.

This water is under line pressure (or pump pressure), which is MUCH higher than the pressure of the steam boiler, usually. At that pressure, the high temperature is below the boiling point in the environment, so the water remains liquid. if it didn't, a heat exchanger wouldn't work because the steam would prevent the thermosyphon loop from flowing.

Steam, Boiler, and Blowdown Pressure are the same. Combustion Efficiency is the % of fuel energy that is directly added to the feedwater and not otherwise lost or used. Blowdown Rate is the % of incoming feedwater mass flow rate that leaves the boiler as a saturated liquid at boiler pressure.

1. "Power boiler" means a boiler in which steam or other vapor is generated at a pressure of more than fifteen pounds per square inch gauge pressure. 2. "High pressure, high temperature water boiler" means a water boiler operating at pressures exceeding 160 pounds per square inch gauge pressure or temperatures exceeding 250 degrees Fahrenheit. 3.
Get A QuoteA 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.

Other than temperature issues, there are other reasons why the hot water boiler system pressure may be too high or too low. Some of these problems include a leak at the baseboard or radiator unit. In addition, if the boiler has corrosion or is leaking, pressure readings will change.

Boiler feed water quality is limited owing to problems of (1) scaling, (2) corrosion, and (3) foaming. In order to avoid these problems, the quality guidelines shown in Table IV have been adopted. Data in Table IV show a major difference between cooling water and boiler feed water quality constraints, in that boiler feed water has a strong relationship between water quality and the pressure of

Working Pressure and Temperature Boilers are classified as either low pressure or high pressure and are constructed to meet ASME Boiler and Pressure Vessel Code requirements. Low-pressure boilers are limited to a maximum working pressure of 15 psig (pound-force per square inch gauge) for steam and 160 psig for hot water (2).
