Quiz 3- Boilers

Can you tell me which of the following statements about a fire tube boiler is/are true?

• It has combustion gases passing over tubes, just like a cozy fireplace!

• It's generally internally fired, making it a hot favorite among boilers!

• It occupies more floor area for a given power output, so it needs a bit more room to shine!

• It can go up to 100 bar pressure, which is quite impressive!

Let's put your engineering skills to the test. Can you identify the type of boiler shown in the diagram?

• Velox

• Benson

• Loeffler

• Lamont

What is/are the feature of a once through boiler?

• drum less

• fire tube

• natural circulated

• supercritical

In a manufacturing plant, Athul Krishna is evaluating the efficiency of different types of boilers used for steam generation. He comes across the Loeffler Boiler and found

• weight is 20% less than other boilers, since drum

  is avoided

• pressurized combustion is adopted

• one third of the superheated steam

  passes to the turbine while two third is passed through

  the water in the evaporating drum

• none of these

What is/are the main advantage of using a Benson boiler?

• Higher efficiency due to no drum

• Ability to operate at supercritical pressures

• All of the above

• Lower weight compared to traditional boilers

In a Lamont boiler, what is the role of the feed pump?

• To regulate temperature

• To remove impurities from water

• To circulate water through the system

• To increase the pressure of steam

A team of Engineers from S5 ME A were asked to distinguish a Cochran boiler. Help them.

• a low pressure, water tube boiler

• a low pressure, fire tube boiler

• high pressure, multi tube boiler

• high pressure, fire tube boiler

What is the primary function of the economizer in a boiler system?

• To preheat the feedwater

• To increase steam pressure

• To remove excess moisture from steam

• To enhance combustion efficiency

Give an example for a low pressure water tube boiler

• Cochran boiler

• Lamont Boiler

• Babcock and Wilcox boiler

• Benson boiler

Select the correct statement/s for high pressure boiler

• Lamont is a high pressure boiler with drum

• There is forced circulation of water through small diameter tubes

• Benson is a high pressure boiler without drum

• The major mode of heat transfer is radiation
