Considering the characteristic of thermite and the concrete structure of the welding rod, the design scheme of special-purpose flameigniter is adopted, and the igniter is designed in detail.
The igniter with multiple slit burner is characterized by its higher combustion efficiency, better adjustment of flame length, more rational temperature distribution in the furnace hearth.
