Abstract
An exhaust duct and boiler can appropriately collect solid particles in flue gas by way of being provided with: a flue (40) in which flue gas can flow; a first hopper (61) that is provided in the flue (40) and that can collect solid particles (PA) in the flue gas; and a first baffle plate (71) and a second baffle plate (72) that are resisting members capable of blocking the flow of solid particles (PA) from the first hopper (61).
Claims5
An exhaust duct comprising:
- a flue gas passage in which flue gas can flow;
- a hopper which is provided in the flue gas passage and can collect solid particles in the flue gas;
- and
- resisting members which can block outflow of the solid particles from the hopper,
- wherein the resisting members include a baffle plate which is disposed on an upper portion of the hopper along a horizontal direction intersecting a flow direction of the flue gas,
- wherein the baffle plate includes a first baffle plate which is disposed on the upper portion of the hopper and a downstream side end portion in the flow direction of the flue gas, and a second baffle plate which is disposed on the upper portion of the hopper and at an intermediate position in the flow direction of the flue gas, and
- wherein the second baffle plate is disposed such that a lower end portion in a vertical direction is inclined toward the downstream side in the flow direction of the flue gas, and the second baffle plate is disposed above a storage portion of the hopper.
