boiler. The pressurized water is vaporized by the hot exhaust and then expanded to lower temperature and pressure in a turbine, generating mechanical power that can drive an electric generator. The low-pressure steam is then exhausted to a condenser at vacuum conditions, where heat is removed by condensing the vapor back into a liquid.
Cycling - Turning equipment on and off frequently can create pressure-vacuum cycles in the equipment. Overtime, this can cause mechanical failure in tubes or jackets. Installing vacuum breakers and air vents is the best strategy for ensuring longevity of your equipment. Keeping It Clean – Boiler piping is usually the dirtiest when it is new
