APPARATUS FOR PREVENTING THE HEAT EXCHANGE TUBE AGAINST EROSION OCCURRED IN SOLID FUEL FIRED SYSTEM SUCH AS SOLID FUEL FIRED INCINERATION UNIT OR BOILER FURNACE USING PARTICLE SEPARATION DEVICE

An apparatus for preventing wear of a total heat pipe of a solid fuel burning unit using a mechanism separating pulverulent bodies in a gas is provided to remarkably extend the life span of equipment at a low cost by preventing wear of the total heat pipe by the collision of the pulverulent bodies. An apparatus for preventing wear of a total heat pipe of a solid fuel burning unit using a mechanism separating pulverulent bodies in a gas includes a flow deflecting plate(110) and a particle separating plate(120). The flow deflecting plate lessens the acceleration of exhaust gas and changes the direction of the flow to prevent deflection of the gas to a portion at which wear is expected. The flow deflecting plate flows the pulverulent bodies along an inclined surface. The particle separating plate introduces the pulverulent bodies flowing along the flow deflecting plate and induces the pulverulent bodies to an inner wall surface of an exhaust conduit.
