Title: Boiler heat exchanger
IPC: F24H9/20
Filed: 2020-04-29
Abstract: The present invention relates to a total heat exchanger for a boiler. The total heat exchanger for a boiler includes a hollow housing, and a multi-burner port burner is installed on an upper side of the inside of the housing, and a flame detection part fixed to the inner surface of the housing, while having one end thereof projected to be parallel with the outer surface of the multi-burner port burner is installed to lead flames to be combusted in the multi-burner port burner, and, as a result, the flames combusted in the multi-burner port burner are equally emitted to the outer surface of the flame detection part formed to be parallel with the outer surface of the multi-burner port burner, thereby improving flame detectability while reducing an error range. According to the present invention, as the flame detection part is installed to be parallel with the multi-burner port burners, the flame detection part and the multi-burner port burner are spaced apart from each other by an equal distance, and the flames emitted from the multi-burner port burner are equally brought into contact with the outer surface of the flame detection part to prevent the flames from being concentrated on one part of the flame detection part, and, in particular, when the flames are emitted from only one part of the multi-burner port burner due to dust or foreign substances, a contact area of the flames in contact with the flame detection part installed to be parallel with the outer surface of the multi-burner port burner is increased to reduce a flame detection error range, and, due to the reduction of the flame detection error range, whether the flames are combusted in the housing can be accurately identified, and, moreover, the outer shape of the multi-burner port burner is allowed to be freely transformed such that the flame detection part can be formed to be parallel in accordance with the shape of the same, to improve flame detectability, which can lead to an advantage of improving the reliability of the product.
