High-pressure boilers will heat steam above 15 psi and water at pressures that exceed 160 psig. Temperatures in high-pressure boilers will exceed 250 degrees F. Because of the elevated pressure at which these boilers operate, they need to be monitored to ensure safety at all times.
Based on pressure steam boiler can be classified as high pressure steam boiler and low pressure steam boiler. A high pressure steam boiler is boiler in which steam is generated at pressure exceeding 15 psig and operates hot water boiler above 160 psig or 250o F. Application this type usually is used for utility plants, big industrial plants and process application.
In a cast-iron modular heating boiler, the operation of the burner of each module is controlled by a blank that starts or stops modules in sequence of load demand increases or decreases.
Boiler pressure refers to the pressure of hot water running in your sealed central heating system, while water pressure is the pressure of the water coming through your taps. Boiler pressure is important for several reasons. Primarily, if you have low boiler pressure your system could cut out, preventing your central heating from working. Alternatively, if there is high boiler pressure, the system will be strained beyond normal capacity and could potentially fail.

Nov 23, 2011 · Difference Between a High Pressure and Low Pressure Boiler. Most of the hydronic boilers used in this capacity run at anywhere from 12 psi (for a boiler that isn’t on) to 30 psi. (The measurement psi is used to determine pressure, and stands for pounds per square inch.) By definition, a high pressure boiler is one that operates above 15 psi,
Maximum Allowable Pressure. Boilers are classified also by their pressure capacity, design type and use. Maximum allowable working pressure, or MAWP, is the highest amount of pressure that the vessel (boiler) is designed to withstand. This pressure is measured in terms of pounds per square inch or “psi,” and gauge pressure is expressed as “psig.”
