1. regulate flow of boiler water
2. check level of water in boiler drum
3. recirculate unwanted feed water
4. allow high pressure feed water to flow to drum and not allow reverse flow to take place
allow high pressure feed water to flow to drum and not allow reverse flow to take place
1. increases
2. decreases
3. remains unchanged
4. increases/decreases depending on steam temperature requirements
decreases
1. reduce hardness and for removal of solids
2. increase efficiency-of thermal power plant
3. increase heat transfer rate
4. increase steam parameters
reduce hardness and for removal of solids
1. corrosion
2. scale
3. carryover
4. all of the above
