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
In terms of efficiency, what is the primary benefit of using an economizer in a boiler system?
It enhances safety features
It increases steam output
It reduces fuel consumption
It lowers operational costs
What is the primary purpose of a superheater in a boiler system?
To increase the temperature of steam
To improve fuel efficiency
To reduce water consumption
To enhance safety measures
What is the main function of a blow-off valve in a boiler system?
To remove sediment from the boiler
To control water levels
To enhance fuel combustion
To release excess steam pressure
