The first successful user of water-tube boilers, however, was James Rumsey, an American inventor, celebrated for his early experiments in steam navigation, and it is he who may be truly classed as the originator of the water-tube boiler. In 1788 he patented, in England, several forms of boilers, some of which were of the water-tube type.
Boilers are part of a hydronic heating system. Hydronic systems use water to transfer heat to a distribution source, like a radiator, to heat a home. Hydronic systems can heat via hot water or steam, depending on the type of boiler used. The boiler is the part of the system that heats the water to be distributed.

Oct 26, 2017 · Water Tube Boiler Design . Whats the difference in application and why use one type over the other? Water tubes are generally considered safer. They contain much less water than fire tubes, so if a disturbance occurs (tube breaks, boiler melt down) there isn’t as much water/steam to have the potential to escape the boiler.
Mar 22, 2013 · Flexible water tube boilers typically consist of an upper and lower water drum with a series of bent steel tubes designed to absorb the stresses of thermal expansion (see Figure 2). The overall efficiency of this application can be relatively low when compared to other types of boilers and piping configurations.

Aug 22, 2018 · A water tube boiler is such kind of boiler where the water is heated inside tubes and the hot gasses surround them. This is the basic definition of water tube boiler. Actually this boiler is just opposite of fire tube boiler where hot gasses are passed through tubes which are surrounded by water.
WNS type boiler can burn oil or gas, which is cleaner than others. This boilers are mainly used in school, hospital, hotel, textile industry, chemical plant, power plant, paper & pulp, pharmaceuticals, refinery, food processing, building materials, etc. It include fire tube boiler, water tube boiler and popular D type water tube boiler.

Generally we use the water tube boiler in order to generate the super heated steam like on steam ships etc. the pressure generated on water tubes is always higher the smoke type of boilers.
The pressure of steam inside the boiler is high, and so the feed water pressure must be raised before its entry into the boiler for consistent operation. Feed pump is a device which raises the pressure of water and forces it into the boiler.
The Use Of Boilers In Industry. Steam boiler and hot water boiler are widely used in industries to supply heat energy or hot water for production. For power plants, large capacity steam boiler are used to generate high temperature high pressure steam for power engine to generating power. There are general introduction of the use of industrial boiler in industry.
Fire Tube or Shell Boilers. This is the most common type of boiler used in small and medium sized industrial installations.

Industrial boilers are primarily used for process heating, electrical or mechanical power generation, or space heating. Industrial boilers are used in all major industrial sector like paper products, chemical, food, and other industries. And steam boilers are the most common boiler type in various applications.
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.
Water tube steam boiler is an important equipment for sugar factory, is the production of power and heat source. The steam boiler is an important equipment of power and heat for sugar industry. With the continuous expansion of sugar production scale, security and energy efficiency, the water tube steam boiler demand is also increasingly.
Water tube boilers are the most widely used boilers. These type has replaced many boilers, including the fire tube type, mainly because of the following reasons : The weight of the water tube boiler is much less than any type of boiler of equivalent size. Steam raising and steam generation process is much faster
The main two basic boilers are: Water tube boiler ; Fire tube boiler ; The design and arrangement of both the types is just the opposite.
