Low pressure boilers work with pressure below 15 psi while high pressure boiler above 15 psi
advanatages of high pressure boilers
High furnace pressure is a direct indication of a disturbance in combustion performance. The rate of change in the furnace pressure can vary very much, that is from a simple sudden surge due to fuel variations to a huge furnace explosion
how are low pressure mercury lights made and how do they operate?
Winds in a tornado are extremely high because the pressure at the center of the tornado is much less than its surroundings, and this pressure drop occurs over a very small distance. Differences in pressure are what cause most winds. The greater the pressure difference over a given area, the greater the wind speed.
Pressure differences are the main driving forces for wind. The greater the pressure difference over a given area, the greater the wind speed. Tornadoes produce very low pressure in a very small area.

The boilers which produces steam of pressure 80 bar or more than 80 bar are called high pressure boilers.

It may lead to caustic embrittlement.
The highest pressure boiler that I ever saw as a marine Chief Engineer was 2400 psi or 80 atmospheres. The US Navy operated 1200 psi boilers for many years. High pressure steam generators in Nuclear plants are usually limited to 600 psi due to the lack of superheating. There are higher pressure boilers for specific applications but these are few and far between. Any boiler over 2400psi carries with it many safety concerns and is problematic to both build and maintain.
Wind blows from high pressure zones to low pressure zones. It does not have a source, it is produced by differences in pressure between different areas.
STEAM High pressure 15 PSI Hot water boilers 160 PSI and or 250 DEGREES F
Typically the area between the systems gets high winds because of the differences in circulation such as a high pressure spins clockwise and low pressure system spins counter clockwise.
Both are large scale circulations in the atmosphere created by pressure differences. A cyclone has a low pressure center and an anticyclone has a high pressure center.
Wind blows from high-pressure areas to low-pressure areas. It does this simply because nature is trying to restore a balance between the different pressure areas.
Pressure differences between warm and cold air masses cause fronts or high/low pressure systems. A warm front is when a warm, moist air mass slides up and over a cold air mass, and a cold front is the opposite.
Wind is the result of differences in pressure in the atmosphere and flows between air masses. It moves from high-pressure to low-pressure regions, in an attempt to even out all different barometric pressures.
