Steam that was reduced in pressure from that at which it was generated in the boiler. Reducing the steam pressure can be accomplished by running it through a turbine or engine, a reducing valve or a regulator. Reduced pressure steam is often used for auxiliary equipment or heating systems after the primary process has been supplied steam at the generated pressure.
What else can I help you with?
What happens when superheated steam pressure is reduced?
steam quality increase
Why is the steam pressure coming out of the boiler low?
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 happen if you heat steam?
If you heat steam under pressure you get "superheated steam" under higher than original pressure
What energy does the steam engine use?
steam engine uses thermal energy to convert water into steam and then uses pressure of steam to move the engine .thus thermal energy into pressure and further pressure into mechanical energy.
High pressure steam turns the blades of?
High pressure steam hits the blades of a TURBINE and turns its shaft.
What happens when superheated steam pressure is reduced?
steam quality increase
How does a impulse steam trap work?
It works on the principle that condensate at a given temperature will flash to steam after pressure has been significantly reduced.
Is the expansion of superheated steam isothermal?
Expansion of steam in either the saturated or superheated state is generally not isothermal. When steam expands from a high pressure to a lower pressure the temperature will be reduced, unless energy is added during the process. When steam expands in an engine such as a steam turbine, the temperature reduction is greater than during free expansion
Why is the steam pressure coming out of the boiler low?

How do you make pressure on alchemy classic?
steam+steam engine=pressure
What happen if you heat steam?
If you heat steam under pressure you get "superheated steam" under higher than original pressure
Where can one purchase a pressure watcher that uses steam?
Assuming that the question relates to pressure washers, one can purchase steam and pressure washers from Karcher UK, Steam and Pressure and Steam Powered websites. They are also available from an Argos store.
What is bleeding of steam in thermal power plant?
Bleeding of steam means Extracting steam from Turbines for heating the feed-water. Normally, there are High Pressure Heaters & Low Pressure heaters in Condensate cycle. Steam bleed out from the turbine gets into these heaters and heats up the feed-water (generally termed as Sensible Heat Addition). The steam that was bled can be re-used as condensate in Deaerators. Steam Extractions although reduce net work output but helps in overall gain in efficiency in terms of Reduced Fuel Consumption.
Who invented high pressure steam broilers?
gumball who ivented high pressure steam broilers
What energy does the steam engine use?
steam engine uses thermal energy to convert water into steam and then uses pressure of steam to move the engine .thus thermal energy into pressure and further pressure into mechanical energy.
Why is fruit cooked by high pressure steam?
Under increased pressure, the boiling point is proportionally higher, so the food can get hotter, so more germs are killed, and the cooking time is reduced. Vegetables may be even more in need of pressure-cooking.
What is the compounding steam turbine?
Velosity compounding:This is a combination of pressure-velocity compounding. Lets say you have superheated steam coming out of the boiler at 70 bar, which is suppose to drive a steam turbine. How many stages of blading required to reduce the pressure to acceptable exhaust pressure so that it does not overheat the condenser?Remember, when you reduce the pressure the kinetic energy increases so is the steam speed. In order to reduce the pessure you must have pressure compounded arrangement. In order to reduce speed you must have velocity compounded. So what is pressure componded?This is an array of nozzles and impulse blades laid out accordingly to mainly reduce the steam pressure as it pass through the respected stages.Notice the pressure drop gradually as it pass through a fixed blade stage, but the speed increases as it pass the same stage. The velocity compounded which is arranged so that you have nozzles,moving and fixed blades laid accordingly. As it enters the nozzle the pressure is dropped, steam velocity inctreased.Then it pass through moving blades which reduces the steam velocity but maintain steam pressure.Then the steam is pass through guide blades or fixed blades where further reduction in velocity but none in pressure.Last stage is moving blades where velocity is reduced but pressure is maintained. How is pressure-velocity compounding accomplished? Answers: It is a combination of pressure compounding and velocity compounding. Steam is expanded partially in a row of nozzles whereupon its velocity gets increased. This high velocity steam then enters a few rows of velocity compounding whereupon its velocity gets successively reduced. The velocity of the steam is again increased in the subsequent row of nozzles and then again it is allowed to pass onto another set of velocity compounding that brings about a stage-wise reduction of velocity of the steam. This system is continued.
