After a comparatively short period, only eight out of the 11 boilers examined exploded. This compared to steam boiler explosions in boilers not examined by the scheme. The serial number and model number uniquely identify the boiler and are used when orderingspares from the manufacturer and in the main boiler log book. An important boiler fitting is the safety valve. Its function is to protect the boiler shell from.

A boiler is a closed vessel in which water is heated, vaporized and converted into steam at a pressure higher than the atmospheric pressure. The heat energy required for steam generation is produced by burning fuel in the furnace. So these are the important boiler accessories and mountings we will discuss today:. What are the boiler mountings? Boiler mountings are those mechanical appliances which are considered essential for operating a boiler smoothly and safely which are usually mounted on the surface of a boiler.

It consists of a vertical pipe A, bottom end of which is flanged and through this flanged end it is mounted on the mounting blocks of the boiler. B is the Gun metal valve, resting over the valve seat C. Valve seat C is fixed on the top of the pipe A by means of a securing ring and screw.

A boiler is used to generate steam at a desired pressure and temperature by transferring heat produced by burning fuel to water to change it to steam. It is a term applied to that device which generates steam at minimum pressure of 3. Heat from the gases produced by combustion is transferred to water, which is then converted to steam. Water tube boiler When water is contained inside the tubes called water tube which are surrounded by flames and hot gases from outside, then the boilers are named as water tube boilers. They are safe, quick steaming, flexible in construction and operation. These boilers are extensively used because they can be built for high pressure and large evaporative capacities.
