When the circulation of water in a boiler is by a centrifugal pump then the boiler is known as?
externally fired
What is the ratio of a boiler burner indicates the flexibility of the burner to cope with variations of boiler load without losing efficiency of atomisation?
turndown ratio
What is the comparison between forced circulation and natural circulation boilers?
Natural circulationForce circulation1.In Natural circulation boiler the circulation is done by means of nature.In Forced circulation Boiler the circulation is done by the means of pumps.2.These type boilers are low capacity boilers.These type boilers are of high capacity boilers.3.The heating of boiler parts is not uniform, so, there are chances of differential expansion of parts and hence chances of cracks are maximum.The heating of boiler parts is uniform, so, there is no chance of differential expansion of parts and hence chances of cracks are minimum.4.These boilers take maximum time from cold start.These boilers take minimum time from cold start.5.There is a scale formation between the water tubes and hence blockage of pipes.There is no scale formation between the water tubes and hence no blockage of pipes.6.These boilers produce lesser steam and have low pressure steam.These boilers produce steam at 30 to 650 tons per hour, at the temp of temp. & 160 bar pressure.
Define boiler and classification of boiler?
Boiler can be classified as below
What is afbc boiler?
Atmospheric Fluidized Bed Combustion Boiler (AFBC boiler) is a type of operational boiler. In a AFBC boiler a little more fluidized bed combustor is added than a conventional shell boiler.

externally fired
What is the ratio of a boiler burner indicates the flexibility of the burner to cope with variations of boiler load without losing efficiency of atomisation?
turndown ratio
A ship is twice as old as the ship's boiler was when the ship was as old as the boiler is What is the ratio of the boiler's age to the ship's age?

Who invented the corner tube boiler?
November 12, 1944, the first basic patent for Corner Tube Boilers (= Eckrohrkessel, Berlin, Germany) was applied for. During this time oil as fuel ran short. All efforts, to save energy and use domestic and alternate resources, were to be made. One came up with an idea, to operate cars and trucks, not on gasoline or diesel fuel, but with steam.Dr. Vorkauf, a specialist for water circulation in boilers, especially in La Mont boilers (forced circulation boilers), got the order to design a small boiler for a steam engine fired with coal or wood. The result was not as expected a forced circulation boiler, but a natural circulation boiler. A forced circulation boiler of this size would have been too costly.Due to his experience with the La Mont boiler Dr. Vorkauf had the idea to obtain a pre-separation of the steam - water mixture in front of the drum. An extremely lively water circulation resulted from unheated downcomers and a suitable arrangement of the mixture tubes. The unheated downcomers were installed in the 4 corners of the boiler, where they not only served the purpose of water circulation, but also as a support frame for the boiler. The boiler with such an arrangement of the downcomers in the corners was called Corner Tube Boiler (Eckrohrkessel, Eckrohr-Boiler).
What is the calculation of sodium and phosphate ratio for high pressure boiler?
3:1
Can poor circulation cause you to be cold?
Yes because water can't get through the pipes in your boiler
How does the water flow in an old cast iron radiator?
The boiler has a circulation pump that circulate the water
How do you calculate energy required to produce 1 kg of steam in Boiler?
The energy required for a boiler to produce 1kg of steam is dependent on the size and pressure exerted by the boiler. The output is described as the boiler horsepower. Once the dimensions are known calculation is a simple ratio.
What is turn down ratio of a boiler?
the effective range in which it can be used; ie the temperature ranges of operation
What is the lambda for cole fired boiler?
Labda is defined as the ratio of actul air ti theoritical air.
What is the advantage of afbc boiler over pf boiler?
afbc has high turn down ratio,burner arrangement is simple,low grade coal can be burnt efficiently,so2 emission can be controlled,
What is the mechanical principle used by a boiler service system?
In modern boiler service systems today, many use a mechanical principle known as forced circulation. Boilers are forced to use this method as the pressure inside the boiler is very high, which means the boiler will have to manually force the water/liquid mixture to circulate so that any progress can be made.
