  1. Steam Boilers and There ApplicationBy: Matt HuntDate: November 2, 2005 Objective: to inform on the basic functions of a steam boiler and some of there applications.

  2. Steam Boiler • A steam boiler may be defined as a closed vessel partially filled with water under pressure from which steam is produced by the application of heat. This head is usually obtained from the combustion of fuel within a furnace. The steam is then used to supply heat to a heating system or manufacturing process or to produce mechanical power.

  3. Boiler Principal • A fuel source (typically an exothermic chemical reaction) heats water • The steam is under pressure (ranging from 50-100 psi residentially and up to 2 600psi at some industrial power plants) and allowing it to apply pressure to the various components of the boiler. • Depending on the boilers application the heated water will turn to steam or stay in liquid form.

  4. Application of Steam • The steam or water can be directly used by flowing through various piping systems (such as Professor Lambert’s in floor heating system) giving off its heat to the surrounding environment. • Alternately the steam can be used to provide work directly (like a steam engine train) or to a turbine which converts the kinetic energy into electric energy.

  5. Heat Sources • Most boilers are fueled by the burning of natural gas. This fuel is used residentially and industrially • The next most typical form of heating is electric which is commonly used residentially. • Another form of fuel is nuclear power, which is used on large industrial levels to produce immense amounts of power. • Occasionally garbage and wood are used as a fuel source, but this is ill practice

  6. Inside the Boiler • Inside the boiler there are numerous tubes running along the walls of the boiler • These tubes have water circulating through them • The water/steam in adjacent pipes are always flowing in opposite direction to optimize heat exchange

  7. Conclusions • Boilers are systems using the exchange of thermal energy to kinetic energy of molecules in fluid. • This fluid can than be put under pressure to do various forms of work or heat transfer.
