Abstract
An apparatus for collecting large particles, such as large particle ash generated during combustion in the thermal power plant, includes a main duct installed between an inlet duct extending in a first direction and an outlet duct extending in a second direction, and connected to the inlet duct and the outlet duct, a hopper installed in a lower portion of the main duct to collect large particles, and a flow switching section installed in the main duct in order to increase large particle collection efficiency by switching a flow direction of gas introduced from the inlet duct.
Claims7
An apparatus for collecting large particle ash generated during combustion in a thermal power plant, the apparatus comprising:
- a first duct extending in a first direction;
- a second duct extending in a second direction different from the first direction;
- a connection duct installed between the first and second ducts and configured to communicate with each of an outlet of the first duct and an inlet of the second duct;
- and
- a side hopper having an opening portion communicating with the outlet of the first duct to collect large particle ash contained in gas flowing from the first duct to the second duct,
- wherein the connection duct includes a lower portion communicating with the outlet of the first duct, and an upper portion communicating with the inlet of the second duct and extending from the lower portion in a third direction perpendicular to each of the first and second directions;
- and wherein the side hopper has a top surface installed on a lower side of the lower portion and is disposed in a direction opposite to the third direction.
