Depends on the situation! It may be needed at only a low pressure. Otherwise it may be the result of reduced heat input or of the input of cold feed-water.

What the inside of steam boiler?
"What the inside of steam boiler?" Would you like to know: with no water and steam, construction, under steam conditions, high loads, high TDS, Low pressure.
What are the components of low pressure steam boiler?
heating ventilating and air conditioning.Type your answer here...
Why to out bleed steam in turbine?
When steam contains liquid droplets while doing work at high temperatures, the water droplets can etch metal. To combat this, steam can be superheated or the pressure of the system is reduced.
Why does a boiler explode?
Low water level along with both a defective high limit safety and pressure relief valve.
Why steam is to be condensed in thermal power plant Y should not you use a compressor to suck compress and send back the steam at high pressure?
It's a matter of the steam cycle, the condenser in a condensing power plant creates a vacuum, or low pressure zone for the steam to flow into. A compressor would need to compress this steam 650 times plus generate enough force to force it back into the boiler, this would require a lot of energy to do. It is much simpler and much more cost effective (energy wise), to condense the steam and exhaust the excess heat to the cooling tower. The condensed water can then be pumped back to the boiler in stages to repeat the cycle. In these stages the water is de-aerated, treated and heated back to the boiler's temperature to prevent thermal shock in the boiler. In short condensing the steam is easier, safer and cheaper than trying to mechanically compress it. **By the way, there are vacuum pumps called "hoggers" or steam powered ejectors, and injectors which could do just what you suggest, but use exorbitant amounts of energy to do so. These are typically used in conjunction with condensers to eject non-condensible gasses from condensers.
What is the highest pressure safety valve allowed on a low pressure boiler?
I believe that is 15 PSI on a low pressure steam boiler
What happens when energy is removed from steam?
A boiler produces steam at a high temperature and pressure. It is used to push a piston or a turbine, to produce mechanical energy. The steam coming out can then be used to drive a low-pressure turbine and so on. At the end the steam can be condensed to extract the latent heat, and then the water goes back to the boiler.
A low pressure steam boiler has a maximum allowable working pressure of up to?
15 psi

How does a low pressure boiler work?
Boilers operating at 15 psig steam pressure or lower, known as low-pressure heating boilers, are classified in SIC 3433.
How many pounds of pressure does low pressure boiler operate on?
A low pressure boiler is any boiler 15 psi or lower
What is platen superheater?
it is a low pressure heater used in the boiler system in the thermal power plants to convert the saturated steam into super heated steam.
What a range of low pressure boiler?
Steam pressure does not exceed 103 Kpa (14.7 psi) in steam boilers, or as long as the temperature of the water does not exceed 121ºC (250ºF) or the pressure does not exceed 1103 kpa (160 psi) in hot water boilers 'Caesar Aborido BCIT'.
What is max pressure in a low pressure hot water boiler?
160psi
Can you pumped exhaust steam directly to boiler?
No. Exhaust steam must be condensed back into water before being pumped back to the boiler. High pressure exhaust is often used to heat production or heating equipment, returned to a condensate tank then pumped to the D/A before being returned to the boiler. Low pressure (vaccuum) exhaust is condensed by a jet condenser or shell and tube condenser before being returned to the D/A.
What questions are on the NJ low pressure boiler test?
