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.
Fig. (2) Shape of fire-tube 2.1.3 Water-tube boilers: • Water-tube boilers have water running through the tubes and fire or gases of combustion surrounding the tubes. The water tubes are connected into a steam drum at the top and a mud drum at the bottom. The fire is in the Combustion chamber. The boiler design can also be

This was a major drawback with the early water-tube boilers, such as the Du Temple design, tested on the French Nord network in 1907 and 1910. (Water tubes in Royal Navy boilers were checked for blockage by dropping numbered balls down the curved tubes, and being very careful that you had them all accounted for)
Scotch - this type of boiler is commonly referred to as a scotch marine boiler. In a scotch boiler, the furnace is a large diameter tube, within the boiler, surrounded by water. Some older, large scotch boilers had two or three furnaces but modern boilers typically have only one.
Our boiler tube cleaners include advanced features to make cleaning boiler tubes faster and easier than ever before. Just a small amount of scale and soot in tubes can drastically reduce boiler efficiency, and Goodway fire tube and water tube boiler cleaner system can help regain efficiency and save on fuel costs quickly.
Cast iron sectional boilers (figure 3) are another type of boiler commonly used in commercial space heating applications. These types of boilers don't use tubes. Instead, they're built up from cast iron sections that have water and combustion gas passages. The iron castings are bolted together, similar to an old steam radiator.
