Abstract
A deaerator includes a tank, a spray unit, a steam supply unit, a bleed unit and a discharge pipe. The spray unit is disposed at an upper portion of the tank and configured to supply water to the tank. The steam supply unit is disposed inside the tank to supply steam to the tank. The bleed unit is disposed at the upper portion of the tank and adjacent to the spray unit. The bleed unit is configured to bleed air from an inside of the tank. The discharge pipe is configured to discharge water without air to an outside of the tank.
Claims9
A deaerator, comprising:
- a tank;
- at least one partitioning means disposed inside the tank that partitions the inside of the tank into at least a first section and a second section;
- a plurality of nozzles disposed at an upper portion of the first section of the tank to spray water toward a lower portion of the tank in a droplet form and distributed along a length direction of the tank;
- a steam supply unit having a plurality of first discharge holes disposed inside the tank and distributed along the length direction of the tank to supply steam to the tank in a same direction as water sprayed from the plurality of nozzles;
- a bleed valve disposed at the upper portion of the tank and configured to bleed air from an inside of the tank;
- and
- a discharge pipe configured to discharge deaerated water to an outside of the tank,
- wherein the plurality of nozzles spray water to only one of the two sections of the tank to cause different water flow condition from each of the sections,
- wherein the steam supply unit includes:
- a first steam supply pipe disposed in the first section extending along the length direction of the tank, the first steam supply pipe including the plurality of first discharge holes;
- and
- a second steam supply pipe disposed in the second section extended along the length direction of the tank, the second steam supply pipe including a plurality of second discharge holes distributed along the length direction of the tank and configured to supply steam in a different direction from the plurality of first discharge holes.

- a tank;
- at least one partitioning means disposed inside the tank to partition an inside of the tank into at least a first section and a second section;
- a plurality of nozzles disposed at an upper portion of the first section of the tank and configured to supply water to the tank;
- a main steam supply pipe extended along a length direction of a lower portion of the tank and configured to supply steam to the tank, the main steam supply pipe including a plurality of discharge holes distributed along the length direction of the tank to supply steam to an upper portion of the tank in a different direction as water sprayed from the plurality of nozzles;
- a bleed valve disposed at the upper portion of the tank and configured to bleed air from an inside of the tank;
- at least one porous plate installed above the main steam supply pipe along the length direction of the tank;
- and
- a discharge pipe configured to discharge deaerated water to an outside of the tank,
- wherein the plurality of nozzles spray water to only one of the two sections of the tank to cause different water flow condition from each of the sections,
- wherein a first porous plate of the at least one porous plate is disposed in the first section and extends along a length direction of the main steam supply pipe between the plurality of nozzles and the main steam supply pipe, a second porous plate of the at least one porous plate is disposed in the second section and extends along the length direction of the main steam supply pipe at a same height as the first porous plate, and a third porous plate of the at least one porous plate is disposed to be parallel with the first porous plate in the first section and extends along the length direction of the main steam supply pipe between the first porous plate and the main steam supply pipe, the first section having a multiple stage of porous plate including the first and third porous plates and the second section having a single stage of porous plate including the second porous plate.
