Which is better fire tube boiler or water tube boiler?
The words are literal , a water tube boiler is water inside the tubes with hot gases surrounding them and a fire tube boiler are got gases within the tubes with water surrounding them.
What are the 2 main types of boilers?
Fire tube and water tube. Steam Boiler and Water Boiler.
What is a water leg in a boiler?
It is the small space between two plates having water and at the other side of the plate hot gases are available to transfer heat to the boiler water. In fire tube boiler space between end plate and combustion chamber's end plate is called water leg.
Why are water tube boilers considered less dangerous than fire-tube boilers?
Advantages of fire tube boilers: - More residual heat in the water to allow for load swings - Simpler control systems due to larger volumes of water in shell - Water quality doesn't change as quickly due to larger volume of water Disadvantages of fire tube boilers - Maximum Allowable Working Pressure is limited due to larger surfaces exposed to pressure, to about 250 psi - Danger of a pressure part explosion due to failure of the shell and resulting rapid expansion of the large volume of water in the shell - Longer warm-up times due to the large amount of water in the shell. - Larger footprint than a water tube boiler of the same rating. - Less efficient per sq. ft. of heating surface since less of the water is in contact with heating surface due to a larger volume of water in the shell. Advantages of Water Tube Boilers - Rapid warming due to a much larger heating surface per pound of water in the boiler. - Easier to have a superheater if necessary - Virtually unlimited Maximum Allowable Working Pressure (within reason) - Smaller footprint than a fire-tube boiler of the same rating - Less working volume of water contained in the pressure parts - More water volume exposed to the heating surface than a fire tube boiler (more efficient) - Faster load change response due to less water - Less chance of a pressure part explosion due to less volume of water exposed to a rupture situation, plus, the rupture is usually into the furnace area which is safer. Disadvantages of a Water Tube Boiler - Must be more careful of feed-water quality - More complex control systems for drum level necessary due to smaller water spaces, (although I have worked in plants with old marine three drum boilers with huge steam drums which only had thermo-hydraulic regulators for drum level) - Operators must be quicker on the draw when there is an upset because everything happens faster with a water tube boiler Rahul Menon Twitter- @menenrahul
Find the heating surface of a water tube boiler tube with a 3 diameter and 20 feet long?
3.14*3*20*12= 2260.8 sq inthe heating surface of a fire tube boiler is determined by adding all of the surface of the tubes that have hot water on one side and/or fire or gases of combustion on the other, including the super heater and economizer.
Which is better fire tube boiler or water tube boiler?
The words are literal , a water tube boiler is water inside the tubes with hot gases surrounding them and a fire tube boiler are got gases within the tubes with water surrounding them.
How does the fire tube boiler operate?
In a fire tube boiler, the water surrounds a set of tubes through which the fire and the products of combustion travel (as opposed to a water tube boiler, in which the water travels through the tubes, and the fire surrounds the tubes).The HVAC Veteran
What is the pass of fire tube boiler?
water
What are the 2 main types of boilers?
Fire tube and water tube. Steam Boiler and Water Boiler.
What is difference between vertical and horizantal boiler?
there are two types of boilers water tube and fire tube. fire tube boilers are divided in to two categories vertical and horizontal. this according to the construction of fire tubes. it is said that vertical boilers are inefficient than horizontal boilers. The vertical boiler is small capacity, and horizontal boiler is higher capacity, well, the horizontal boiler have many types according the drums, there are single drums boiler, and double drums boiler, while, the single drums boiler have fire tube boiler and water and fire tube boiler, double drums boiler is usually water tube boiler.

Difference between fire tube boiler and water tube boiler?
The difference between the two is that the Water tube boilers are safer and last much longer than the fire tube boiler. Their size is also larger and have a faster recovery time. However fire tube boilers have a low cost.
What is a simple vertical boiler?
A simple vertical boiler is a type of fire-tube or water-tube boiler where the boiler barrel is oriented vertically instead of the more common horizontal orientation.
