Where is velox boiler used?
velox boiler is a forced circulation water tube boiler. It is mostly used in gas turbine. In this boiler, the velocity of flue gases is greater than the velocity of sound, which causes more heat transfer from gas to the water, which increases the steam generation rate. Due to this, it is most important boiler.
Which feature makes the velox boiler a unique boiler?
The Velox boiler uses GAS in the combustion chamber. This boiler has a unique core principle compared to other boilers that we have already discussed. When the velocity of the GAS exceeds the velocity of the sound, the heat transfer rate makes the GAS much higher than the rate obtained in the subduction current.
What boiler is in a velox boiler?
4. What type of boiler is a Velox boiler? Explanation: Velox boiler is a forced circulation boiler. It has gas turbine driven air compressor, which compresses the air.
What is unique feature of velox boiler among all other similar boilers?
The special characteristics of the Velox boiler : high efficiency, small Space requirements, quick starting and fully automatic regulation are advantages which are as much appreciated for hot water production as for steam generation.
What is the major disadvantage of the Benson boiler?
Explanation: The major disadvantage of the Benson boiler is that when water transforms into steam in the convective section of the evaporator, salts are deposited in the transformation zone.
What is Babcock boiler?
Babcock And Wilcox Boiler is a stationary water tube boiler. It consists of the steam-water drum. a short tube connects the steam water drum with the uptake header and down header as shown in the figure. A mud box is equipped with each down space header and the mud collected, is removed.
What is the advantage of having smaller ratio of water to steam space?
Explanation: Rate of evaporation is more as area of heating surface is more due to presence of large small diameter tubes. Due to that smaller water ratio is allowed to steam space where in the steam can be generated as a faster rate even if the boiler is cold.
What is the major advantages of the Benson boiler?
Advantages of Benson Boiler The cost of the boiler is low because there is no water and steam drum. There is no pressure limit, therefore supercritical pressure may be used. The high pressure avoids the bubble formation in the tubes which increases the heat transfer rate. It is a lightweight boiler.
What is the main disadvantages of Lamont boiler?
Disadvantages of Lamont Boiler: The main disadvantages are Bubble formation on a surface of the tube reduces the heat transfer rate. For this reason a little problem with the total amount of steam generation.
Is Babcock and Wilcox a high pressure boiler?
The Babcock and Wilcox boiler is used in almost all power generation industries because it can produce high-pressure steam. This high-pressure steam is further used to generate electricity.
What is the major disadvantage of the Benson boilers?
What is the principle of Velox boiler?
This is the basic principle of of it. This boiler can increase the heat transfer rate or can say steam generation rate without increasing boiler size. This is why; Velox boiler is most successful boiler in the gas turbine industries. Velox boiler is a water tube forced circulation boiler.
How to increase the heat transfer rate of Volex boiler?
In this boiler heat transfer rate or stream generation rate can be increased without increasing the size of the boiler. It can be increased by simply increasing speed of gas. Volex Boiler contains many parts.
What is Velox and why is it important?
The great significance of the Velox idea lies in the fact that by means of the increase in pressure and velocities the components are greatly reduced in size, and the processes are accelerated without impairing the efficiency.
