Commercial boilers are designed with a firetube, small water tube, and electric resistance. They work ideally for universities, libraries, office buildings, schools, laundries, hospitals, and other similar facilities, Among the different types of boilers, commercial boilers are some of the most diverse.
Water tube boilers. Industrial water-tube boilers work in the opposite way: water is circulated inside the boiler tubes and the tubes are surrounded by hot gases. This type is relatively rare in the UK, but much more common in other parts of the world.
Cleaver-Brooks Nebraska offers the industry's widest range of natural circulation watertube steam generators and industrial boiler designs. Every aspect of our system is designed for maximum efficiency, reliability, and low emissions.
Water tube boilers For steam generation in large installations or in particularly heavy applications, water tube boilers are the ideal solution. With this type it is possible to produce up to 50 Ton/h of steam, saturated or superheated, with pressures up to 50 barg.
In the same way, a fuel source is burned in the furnace, causing the water tubes inside to heat up. Once again, when the water is boiled, steam is generated and moved downstream. A water-tube boiler is more thermally efficient than a fire-tube boiler, but they are more complex to construct and the quality of the water can be a limiting factor.

Fire tube boilers are useful for small demands of steam and water tube boilers are useful for industrial level usage. To cut short the main purpose of boiler is to boil a liquid mostly the water in order to generate the steam for serving the purpose of heating a building or running an equipment through pressurized steam or pressurized water.
Fire Tube or Shell Boilers. This is the most common type of boiler used in small and medium sized industrial installations. Fire tube boilers are often produced as 'packaged' units complete with pumps and control system, requiring only connection to a suitable water and fuel supply before commencing operation.
Inspection and Test Plan for Water Tube Boiler You may also want to review boiler inspection and water tube boiler inspection procedure /instruction articles. The ASME Code Section I requirements are normally applied for the inspection and test plan in a manufacturing shop.
Industrial boilers can be categorized based on design, fuel used to generate heat, or combustion technology. In regards to design, there are two main concepts. Fire tube boilers and water tube boilers. Fire tube boilers are easy to operate and have a simple design.
Boiler start-ups and shutdowns can add a tremendous amount of deposit to the boiler tube wall. The number of start-ups is a better predictor of tube deposit density than operating hours. Time-based cleanings do not consider water chemistry (good or bad) or the amount of deposits since the last cleaning.

Working Principle of Water Tube Boiler . The working principle of water tube boiler is thermal siphoning (circulation of natural water). Basically, this type of boiler includes two drums namely steam, lower or mud drum. The water tube boiler diagram is shown below, and these two drums are associated via two tubes such as downcomer and riser. At
boiler small enough to fall down a tube. Remove watches, rings, ear rings, etc. that may fall into the boiler. Ensure the battery compartment on your camera closes securely. The last thing you want to do is spend the rest of your day with a high pressure hose flushing tubes in a water tube boiler until your dropped item is found.

The examples of the fire tube boiler are: simple vertical boiler, Cochran boiler, Lancashire boiler, Cornish boiler, Locomotive boiler, Scotch marine boiler and Velcon boiler. (ii). Water Tube Boiler: In water tube boilers, the water is present inside the tubes and the fire or hot gases surrounds these water tubes.
The firetube boiler is primarily used in industrial applications. Firetube boilers are compact, low in initial cost, and easy to modularize based on plant requirements. Firetube boilers usually range in size from less than 2 to 50 million Btu/hr. Most industrial firetube boilers are either of horizontal return tube (HRT), scotch marine, or
Feed-water purity requirements therefore can vary widely. A low-pressure fire-tube boiler can usually tolerate high feed-water hardness with proper treatment while virtually all impurities must be removed from water used in some modern, high-pressure boilers. Only relatively wide ranges can be given as to maximum levels of alkalis, salt, silica

Fire-Tube Boiler (~1800) The fire tube boiler, the oldest design, is made so the products of combustion pass through tubes surrounded by water in a shell. The furnace/flame volume can either be inside or external to the shell that contains the water. The upper steam capacity of fire tube boilers is about 20,000 Ibm/hr, and the peak pressure

In watertube boilers, boiler water passes through the tubes while the exhaust gases remain in the shell side, passing over the tube surfaces. Because tubes can typically withstand higher internal pressure than the large chamber shell in a firetube, watertube boilers are used where high steam pressures (3,000 psi, sometimes higher) are required.
How an industrial boiler system works The heart of an industrial boiler system is a hot water or steam boiler operated with a certain kind of fuel. The boiler heats up or evaporates the water inside it, which is then transported to the consumers via pipe systems. In case of hot water the transport energy is generated by
