Boiler inspections are mandated to be carried out in states and municipalities having boiler safety laws. These are called jurisdictional inspections. In most states these laws call for inspection of water-side systems (water level controls and pressure-retaining devices), but not testing of fuel train safety devices.
boilers now operate at the pressure of the incoming cold water mains, this is still far below the normal operating pressure of steam-raising boilers. This leaflet applies to steam and high temperature hot water boiler plant (operating above 0.5 bar pressure and a temperature of 110 °C). It describes a process which
The steam turbine is a device for obtaining mechanical work from the energy stored in steam. Steam enters the turbine with a high energy content and leaves after giving up most of it. The high-pressure steam from the boiler is expanded in nozzles to create a high-velocity jet of steam. The nozzle acts
The boiler involved in the accident was a 2000 built Cleaver-Brooks CB Packaged high-pressure steam, gas/oil fired, 400 horsepower, and 150 pounds per square inch (psi) firetube boiler. The boiler bears the ASME "S" stamp and National Board registration number 10409. The boiler is
On the front of the boiler is an external reversing chamber, which again reverses the flue gases and leads them to the end of the boiler in the 3rd smoke tube pass. Hot water boilers are normally completely filled with water during operation. Steam boilers on the other hand are only 3/4 filled with water; the upper quarter is the steam space.
Most intermediate pressure steam (IP steam) is exported for process and heating to a host plant nearby – the Dayton Bridgestone Firestone facility. Low-pressure steam is used for boiler feedwater deaeration. Turbine exhaust steam is condensed in a Yuba condenser, tied to a 4-cell Hammond cooling tower.
