Is it possible to run a steam boiler very much lesser than design pressure for a long time?

Absolutely. Typical practice is to operate boilers at less than design pressure to reduce stress on the boiler parts. The boilers last longer than design, often.

Is there a greater or lesser air pressure on top of the wing when lift occurs?
There has to be lesser air pressure on the top of the wing to provide lift.
Does air pressure change with altitude?
The higher up you are the lesser the air pressure in the atmosphere.
Why boiler drum manholes are elliptical in shape?
as the boiler drum is cylindrical in shape due to low stress concentration and in both end the diameter will be less.so for easy entry into the drum for a man the drum man hole is elliptical in shape.
Why is it easier to push a sharp pin into a board rather then a blunt pin?
Pressure is inversely proportional to area. A sharp pin has lesser area compared to a blunt pin. Therefore we require lesser pressure to push the pin with lesser area.Hence it's easier to push a sharp pin which has lesser area.
How does reducing the volume of a gas affect its pressure if the temperature of a gas and the number of particles are constant?
At a constant temperature, the volume and the pressure are inversely proportional, that it, the greater the volume, the lesser the pressure on the gas, and viceversa.
Are there stairs design made by someone famous?
There would most likely not be staircase designs made by someone famous. Staircases are a lesser field of design. Building is also a sort of quiet art.
How does reducing the volume of a gas affect it's pressure if the temperature of the gas and the number of particles are constant?
At a constant temperature, the volume and the pressure are inversely proportional, that it, the greater the volume, the lesser the pressure on the gas, and viceversa.
How is the pressure affected by the collision of gas particles?
The more the collisons the higher the pressure, the lesser amount of collisons the lower the pressure.
Why is the front wheel of a two wheeler given lesser pressure?
Generally more weight is over the rear wheel.
Why aren't deep sea fish crushed by the earth to Miranda pressure of the water above them?
Some creatures have adapted to living in the great pressure found in the depths of the oceans. If they are brought up to the lesser pressure at the surface, they don't usually survive.
Can air pressure alone cause a piece of bologna to be pushed into a bottle?
Excluding mechanical force or gravity (small bologna, large mouth bottle), it is only air pressure that pushes a bologna into a bottle. It is the pressure difference from the atmosphere and the lesser pressure (vacuum) in the bottle. There is no such thing as "sucking." It is all about pressure differential.
How do mountaineers get altitude sickness?
Well this is due to lesser oxygen in air and hence body gets less oxygen and due to low pressure even lesser makes it to brain and hence headache and tiredness. Thats what is altitude sickness.
