The water tube boiler forces water through tubes and heats these tubes from the outside. This is done in a combustion boiler, or in the steam generator of a pressurized water nuclear reactor. It could even be done in a thermal vent in a geologically active area. The heat penetrates the tubes and increases the thermal energy of the water in the tubes and turns it to steam. The steam is sent to do work, as in a turbine. The steam loses thermal energy as it passes through the turbine, and it eventually exits the turbine as low energy steam. It is then dumped into a condenser. Here the "last little bit" of the steam's energy is removed by the cooling water passing through tubes in the condenser, and the steam is turned back into water. The water is them pumped back through the water tubes in the boiler or steam generator to repeat the cycle. The

What is the boiler capacity unit?
Boiler loads, or the capacity of steam boilers, are often rated in boiler horsepower, lbs of steam delivered per hour, or BTU. Large boiler capacities are often given in lbs of steam evaporated per hour under specified steam conditions. Since the amount of steam delivered varies with temperature and pressure, a common expression of the boiler capacity is the heat transferred over time expressed as British Thermal Units per hour.
What is entrainment in the boiler?
There are basically two types of boilers one is the conventional boilers with a drum or shell in which water (obviously well treated water) is heated and as it is heated it produce stem. The steam occupy the top space and the bottom part is filled with water hot and pressurised. When the process requirements whether it is for steam turbine or for chemical process we need dry steam. If the water level is too high and or if the boiling velocity is too high the water droplets instead of leaving the boiler drum as steam some water droplets leave with the steam. This is no good for the process as we need steam but we are getting water. This water entering the system is called entrainment. If the boiler is highly rated i.e. we are heating too much and heating very hard then the top of the water face on the drum through which the steam leaves takes water drops as well. This is called entrainment. Regards Stephen Pathmarajah
What are boiler scale remover?
Removes scale deposits from in side a boiler where hard water conditions exist NORMALLY on steam systems
What is a Binary Vapour Cycle?
A binary vapour cycle is a representation of a mercury cycle and a steam cycle on a same scale.In this vapour cycle there is comparison between the mercury cycle and steam cycle. In mercury cycle there occurs isothermal expansion of saturated water from boiler into dry saturated steam followed by isentropic expansion followed by condensation of steam and at last heating of steam and thus mercury has completed the cycle in 4 way process. In steam cycle first ther is isothermal expansion which results in converting of saturated water into dry saturated steam followed by superheated process where the steam is superheated followed by isentropic expansion of superheated steam followed by condensation of exhaust steam and at last heating of steam thus completing the cycle.
What is the priming and carryover?
Priming occurs when a boiler has a high dissolved solids content which increases the surface tension of the water. Steam bubbles breaking through this surface tension often carry water over into the steam outlet of the boiler. Priming, also known as foaming, is what causes the carryover.
How is steam produced in a boiler?
Steam is generated by heat from the combution of fuel in a furnace or by waste heat from a process. The heat is transferred to water in the boiler shell, which then evaporates to produce steam under pressure.
Boiler steam pressure?
What you meant by this question is uncertain. If you are asking about the definition then Boiler steam pressure is the pressure developed by a water steam boiler, else if you are asking about the Rated boiler steam pressure then it is the safe operating pressure a boiler can operate, else if you are asking about Maximum boiler steam pressure then it is the maximum pressure that a boiler can produce with out failure.
How do you create boiler in doodle god?
metal + steam = boiler
What are the boiler parts and function?
steam boiler
What is the use of steam drum in boiler?
The steam drum separated the steam from the water and stream mixture in the boiler drum.
How boilers are classified?
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. Application this type usually is used for utility plants, big industrial plants and process application. A high pressure steam boiler can be named as Power Boiler, in which design and construction rule following to rules of ASME Boiler and Pressure Vessel Code Section I - Power Boiler.
Who invented the steam boiler furnace?
Granville T. Woods invented the Steam Boiler Furnace
How do you make boiler in alchemy?
Metal + Steam = Boiler

Why you use boiler in oil refinery?
Use of water in a refinery is makeup for boiler feed. The chief uses of steam are for stripping, steam distillation, and vacuum distillation. The steam comes in contact with the products in these operations, and generally the steam condensate is so highly contaminated that it cannot be reused for boiler feed or for other purposes. Steam is also used for process heating, for pumping, and, in some refineries, for generating electric power
Is steam reversible?
Yes. Steam is produced in a steam generator (boiler), used to power an engine (or turbine), condensed, and returned to the boiler as feedwater.
