Along coincidence and it is fixedly connected.
Further are as follows: the main pipeline and secondary duct are arranged in parallel, sealing welding after the curved pipe is docked by three straight tubes
It connects to be formed, is located in the middle straight tube both ends in three straight tubes and is vertically arranged respectively with the main pipeline and secondary duct；It is this
Structure, the hot fluid flowing in the present invention are more smooth.
A kind of radiation type melting furnace, it is characterised in that: including the gas fired radiant tubes.
Beneficial effects of the present invention: the present invention is easy to produce and is processed into large-scale p-type gas fired radiant tubes, at the end of main pipeline
Flange is set at mouthful, small-bore air inlet pipe and an air outlet pipe can be sealed and be installed on connecting flange, and pass through connection method
Blue and flange is fixedly connected with main pipeline；Straight tube is arranged to side and thrown by setting straight tube for connecting main pipeline and secondary duct
Shadow is the structure of isosceles trapezoid, so that structure is more stable after main pipeline is connected with secondary duct；When transverse tube is connect with main pipeline, in master
Setting is projected as the connection breach of isosceles trapezoid on pipeline, and connects semicanal by arc and connect transverse tube, and increasing connection area makes
It obtains good connecting effect and structural stability is high.
