Nov 23, 2011 · By definition, a high pressure boiler is one that operates above 15 psi, while a low pressure boiler is one that operates at 15 psi or lower. 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.

Jun 06, 2016 · If the load is the same in both cases, the low-pressure steam will move through the pipes much more quickly than the high-pressure steam. The reason is simple: High-pressure steam fits into a smaller space than low-pressure steam. The pressure squeezes it. You wind up with less volume.
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.

The rental boiler units are available in portable trailers or skid mounted and can be fired with fuel oil or natural gas.
When the steam pressure in the boiler drops 10 psi, the boiler will start up automatically. When the pressure reaches to 250 psi, it will shutdown the boiler. In case of modulating pressuretrol it controls the boiler firing at high and low within adjusted range with the help of modulating motor linked with fuel valve.
Steam Pressure Reduction: Opportunities and Issues. Some of the main potential losses in a steam system are noted in Figure 1. Only the energy losses that can be reduced by lowering steam pressure will be discussed in this technical brief, and are listed below: • Steam leaks from high-pressure . components (e.g. valves and piping)
Typical operating temperature settings on a boiler call for a Low temperature (boiler cut-in) between 120 and 160 °F. Typical operating temperatures on a hydronic boiler call for a high temperature (boiler cuts off) of 180-200 °F.

Our exclusive stainless-steel knockout baffle travels the length of the steam drum for maximum steam quality at the outlet and a rapid steam-generating time of 15 minutes from a cold start.
High Pressure Boilers Working. Before converting to steam, water circulates multiple times from shell (water drum) to water tubes and then back to shell.During the circulation, the temperature of water increases as it comes in indirect contact with flue gases that transfer heat through tubes.
Proper controls of these high pressures and temperatures are necessary to prevent catastrophic events from happening. Because two drums are needed for water containment, water-tube boilers are extremely large and heavy and typically have a much higher initial capital cost. Pressure and Temperature Switches in Industrial Boilers
A pressure switch in the steam chamber stops the burner if the pressure gets too high. If the burner continues firing even when steam flow is low, the boiler pressure can build and the vessel can explode.
