A reducing agent supply device for supplying a reducing agent to a portion of a passage for a flue gas upstream of a SCR catalyst includes at least one header pipe extending in the passage and configured to allow the reducing agent to pass through; a plurality of injection nozzles disposed on the header pipe at intervals along an extension direction of the header pipe and configured to inject the reducing agent into the passage; a heat shield plate disposed on an upstream side of the header pipe with respect to a flow direction of the flue gas and having a longitudinal direction along the extension direction of the header pipe; and at least one fixing part contacting each of the heat shield plate and the header pipe and fixing the heat shield plate to the header pipe.

Reducing agent supply device and denitration device

In an exhaust duct and a boiler, there are provided: a flue gas duct through which flue gases pass; a first hopper provided to the flue gas duct, the first hopper collecting PA in the flue gases; a low-repulsion section provided to the upstream side or the downstream side of the first hopper in the direction of flow of the flue gases, the low-repulsion section having a lower coefficient of repulsion than the inner wall surface of the flue gas duct; and a popcorn-ash-trapping section for trapping PA in the flue gases, the popcorn-ash-trapping section provided to the downstream side of the first hopper and the low-repulsion section in the direction of flow of the flue gases, whereby it is possible for solid particles in the flue gases to be properly trapped.

Exhaust duct and boiler

There is provided a safety device for aircraft, that prevents an explosion of a fuel tank storing aviation fuel, the safety device including: a flame arrester that is arranged near an end of a ventilation passage on an aircraft outer side, as a part of the ventilation passage allowing the inside of the fuel tank and an outside of the aircraft to communicate with each other, to prevent a flame propagation into the fuel tank from the outside of the aircraft through the ventilation passage; and a heat transfer reducing part that is arranged closer to the outside of the aircraft than the flame arrester to prevent heat transfer to the fuel in the fuel tank from the flame.

Safety device for aircraft

An exhaust duct and boiler can appropriately collect solid particles in flue gas by way of being provided with: a flue () in which flue gas can flow; a first hopper () that is provided in the flue () and that can collect solid particles (PA) in the flue gas; and a first baffle plate () and a second baffle plate () that are resisting members capable of blocking the flow of solid particles (PA) from the first hopper ().

The present invention provides a water inflow prevention device that prevents an inflow of water into an aircraft when the aircraft lands in water through a communication passage allowing the inside and outside of the aircraft to communicate with each other. The water inflow prevention device includes a mesh part provided in the communication passage, through the mesh part a fluid flowing through the communication passage passes.
