atmospheric pressure. Firetube steam boilers are composed of a cylindrical hull filled with thermal insulation in which a series of tubes are contained. Hot air from a burner is passed from a furnace in the 1st pass to a series of tubes in the 2nd pass, then to aLearn More
Boiler Pipe Insulation In addition to the main boiler body, the pipes connecting to your boiler should also be insulated with removable insulation blankets. This prevents energy from radiating into space from uninsulated boiler pipes. It also lowers the touch temperature of the piping, making a safer workplace.Learn More
Such watertube boilers in thermal power stations are also called steam generating units. The older fire-tube boiler design, in which the water surrounds the heat source and gases from combustion pass through tubes within the water space, is typically a much weaker structure and is rarely used for pressures above 2.4 MPa (350 psi). A significant Learn More
