Whenever the temperature in the boiler is about 212°F, and the relief valve discharges, the sudden pressure drop causes the higher temperature water to flash to steam. Thus the discharge capacity of an ASME relief valve is tested and rated on steam. Basically the emergency stage is caused by an over-firing of the

How Does Cascade Control Work? | West CS

Example of a Cascade Control Application In the example below a product temperature is being controlled via a heated oil jacket. The maximum input represents 400ºC, thus restricting the jacket temperature. At start-up the master compares the product temperature (ambient) to its setpoint (300ºC) and gives maximum output.

BASIC WATER TREATMENT OF STEAM BOILERS

2000-5-2 · The only way to control the cycles of concentration in boilers is to remove (blow down) some of the highly concentrated boiler water. Makeup water replaces blow down and dilutes the remaining boiler water. Blow down is performed two ways; bottom blow down and surface blow down. Ideally, blow down should be done in proportion with steam production.
