To control the alkalinity of boiler water which is directly related to pH control.
Too alkaline will cause stainless steel to brittle while too low alkalinity will cause corrossion.
Phosphate(PO4) is basically reacts with mineral dissolved salts in water and percipitates at high temperature. Generally we maintain 10 - 30ppm PO4 inside steam drum to avoidany deposition.
After moving the blade of the turbine , steam gets falls down in a pit where it gets accumulate and converts to water .again the pump tack up that water removing dissolved oxygen in deairater goes to feed pump , which again feeds to boiler. This the closed circuit .
the main plants that clean water are the ones that live in it they clean it so they can feed on it so the plants that do this are moss and seaweed
Because tropical cyclones feed off of the moisture of oceans and the warmer the water is, the stronger and faster the hurricane will growDo_tropical_cyclones_form_over_land
save water and not waste it, water scarcity is an issue that will greatly affect the amount of crops grown and will determine whether there is enough food to feed and give water around the world. so stop wasting water.
the pH value in boiler feed water is 9.2
Boiler feed pumps are an important part of any boiler operation. They control the amount of water fed to the boiler and the manner in which it is fed.
Boiler feed is the fresh or treated water to replenish the water loss though evaporation or leak
Phosphate(PO4) is basically reacts with mineral dissolved salts in water and percipitates at high temperature. Generally we maintain 10 - 30ppm PO4 inside steam drum to avoidany deposition.
A digester feed pump forces water to a boiler. It works by transferring cool water to the boiler to be heated.
Function - It adds the pressure to the feed water before it entyers into boiler feed pump suction Advantage - Ensures high margin NPSH A for boiler feed pump spinning at high rpm (5250Rpm) Drive for booster - Normally @1450 rpm Type of impeller- Mostly preferred Double suction
Oils and water are not miscible.
by check valve, one and a half times the pressure of feed water
1ppb for O2 and CO2
In boiler feed water line the NRV is normally installed between Pump and stop valve if the line is short and an another NRV is installed at boiler entrance and after stop valve if the line is long or pump is 10 to 15 m away from the boiler.
dear, both morpholine and hydrazine or ammonia are used in conjunction. morpholine is a base which is used for adjusting the PH of boiler feed water.
