What are the 2 main types of boilers?

Fire tube and water tube. Steam Boiler and Water Boiler.


How do you lower the water level in my boilers sight tube its too high im not getting enough heat to my second floor?

There should be a drain valve on the boiler. Drain it to the desired water level there.


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

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 are baffles in water tube boilers?

Baffles in water tube boilers are generally spiral twisted pieces of metal (though other methods have been used) inserted into the flue tube to cause turbulence, in addition to back pressure for better heat extraction. Typically, the design is to break the laminar flow in the exhaust gases and allow a better heat transfer through the tube. This will lower stack temperature and increase over all thermal efficiencies in water tube boilers.


What are some applications for a water tube boiler?

Water tube boilers are used in marine and stationary applications. A water tube boiler heats by water flowing through tubes and being heated by fire externally.


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.


Are all water tube boilers suspended from overhead or set on columns to take care of expansion and contraction?

No. Most, like Stirling, B&W and Heine boilers are suspended from steel work with cleats or U-bolts, however some designs are not suspended. A small vertical water tube boiler could have been mounted on a base with the expansion from heating moving upwards. A Clayton steam generator is a coiled boiler mounted on a base. Robert's or Almy marine boilers are mounted on bases. Automotive water tube boilers were mounted on automotive frames.


Why pressure is low in fire tube boilers?

Hot pressure


Do boilers use water?

boilers sometimes do use water only for cleaning and drying clothes


Where can I buy industrial boilers online?

Powermechanical.com, cleaverbrooks.com, and Reimersinc.com are examples of websites that offer industrial boilers. These are reliable websites and offer good deals on boilers.


Difference between water tube boiler and fire tube boiler?

The answer is in the name. Boilers are made with a "tube - in - shell" construction, and the name implies what is in the tube. In a water tube boiler, the water circulates through the tubes, and the burner is usually under them. Most of the time, the "shell" of this style of boiler would not be watertight. A fire tube boiler has a watertight outer jacket with tubes through the center of it. The flame is shot through the tubes.
