The invention relates to radiation burners and can be used in industrial furnaces.
The aim of the invention is to improve installation and increase reliability by eliminating local overheating.
The drawing shows a heat pipe, a longitudinal section.
The ceramic heat pipe consists of separate thin-walled ceramic tubular elements 1 connected to each other with end sections and provided externally with centering radial ribs 2 supported on the shell 3, in which the heat pipe is enclosed. The outlet end sections of the e: gement 1 pipe are provided with annular ledges 4, and the input end sections have sockets 5, covering partly and with a gap 6 of the mouth of the 4 previous elements 1. In the connection area of the end sections, protective ceramic rings 8, overlapping along the ledges 4 and (at least partially) sockets 5 adjacent elements 1 pipe. The protective ceramic rings 8 have an annular support platform 9 placed between the end surfaces of the ledge 4 and the bell 5 of the adjacent elements 1. The input element 1 The pipes inside the socket 5 are equipped with an auxiliary ring 10 placed in the gap in the socket 5 of this element: and having their centering ribs 11 Centering ribs 2 are placed on the surface of protective ceramic.
rings 8. In addition, the elements 1 tubes are made of pure silicon carbide.
The heat pipe works as follows.
Combustion components enter the inlet element 1 of the pipe and burn in the pipe. Combustion products are discharged through the gap between pipe elements 1 and shell 3.
The design of protective rings and end sections of elements 1 provides a labyrinth design of annular gaps, excluding the radial release of hot combustion products into the annular gap by elements 1 of the pipe and shell 3, and elements 1 of the pipe can be relatively far away when the pipe 1 bends from the other without breaking the tight connection between elements 1.
The implementation of the elements 1 of pure silicon carbide ensures their high resistance.
