Steam explosion - Wikipedia

behavior of steam in the feed processing system When water begins to boil, it has reached the boiling point of saturated water, at which it can take no more energy without changing into vapor (steam). At sea level and under atmospheric conditions the boiling point of water is 100°C (212°F).

EDTA – Water Technology Report

When the temperature of the steam drum falls below 90 o C, drain the boiler. 17. After the boiler is completely drained, fill the boiler with clean rinse water to the top of the gauge glass. Allow the boiler to cool until it is cold enough to enter for inspection. Drain the water. 18.

Steam generation, control, and quality for feed manufacturing

Fire the boiler to take the pressure approximately 10 kg/cm²G in about 8 hours. Maintain this pressure for 4 hours to make sure circulation. Close up the drum vents while the drum pressure gets to 2 kg/cm²G. At the same time check out expansion of the unit wherever doable.

Proper Commissioning and Initial Startup Procedures Extend

Soda locomotives were a variant of fireless locomotives, in which steam was raised in a boiler, expanded through cylinders in the usual way, and then condensed in a tank of caustic soda that surrounded the boiler. Dissolving water in caustic soda liberated heat, which generated more steam from the boiler, until the caustic soda became too dilute to release heat at a useful temperature.

boiling point. No steam pressure should be generated. Continue this step for at least three to five days. 6. After the boil-out period, allow a small amount of water to enter the boiler to create a slight overflow condition. Continue to boil and overflow until the water clears. 7. Shut the burner down. 8.

May 29, 2018 · It is recommended that your new firetube boiler be boiled-out before placing it into service. This may be done before or immediately following initial start-up. A proper boil-out will remove any grease or oil that may still be present in the waterside of the boiler as the result of boiler installation. A clean boiler waterside is one of the requirements of establishing and maintaining a stable

Caustic corrosion in boilers - Lenntech

A steam explosion is an explosion caused by violent boiling or flashing of water or ice into steam, occurring when water or ice is either superheated, rapidly heated by fine hot debris produced within it, or heated by the interaction of molten metals (as in a fuel–coolant interaction, or FCI, of molten nuclear-reactor fuel rods with water in a nuclear reactor core following a core-meltdown).

Boilout Procedure - Sulphuric Acid

Oct 29, 2019 · A soda locomotive was essentially a steam locomotive, but instead of a firebox to burn coal and heat the boiler, it used chemical reaction to generate heat. In a soda locomotive, the boiler was jacketed by a container loaded with several tons of caustic soda, or sodium hydroxide. Water was added to the caustic soda to start a violent exothermic

How to Choose Industrial Boiler Cleaning Agent | Reliable

Especially downstream turbines are sensitive for pollutions in the steam. To avoid damages of the plant, boiler drums and all water-bearing parts have to be boiled out with alkaline chemicals before commissioning the plant. In the past conventional chemicals as trisodium phosphate, caustic soda or hydrofluoric acid were used.

Jun 12, 2021 · Open drum vents and through the chemical cleaning header, pump into the boiler the dissolved concentration sodium carbonate which should be equivalent to 0.5-1.0% sodium carbonate when boiler is filled to normal firing level. Operate boiler feed pump and continue to fill to normal firing level. Fire the boiler until a minimum of 7 bar is reached.

Typical Firetube Boiler Boil-out Procedure

2. the boiler-water must contain caustic, 3. at least a trace of silica must be present in the boiler-water, and. 4. some mechanisms, such as a slight leak, must be present to allow the boiler water to concentrate on the stressed metal. Stem blanketing is a condition that occurs when a steam layer forms between the boiler water and the tube wall.
