Ribbon burners are manufactured from standard steel tubing milled with a narrow slot and fitted with  stainless steel crimped ribbon packs. The ribbon packs form  linear flame burners of any length and heat output, with very uniform flame pattern and heating effects. Single-zone or three zone designs are available as standard. The crimped ribbon pack interlocks to form small low velocity flames to stabilise the main ports, which are constructed in standard arrange-ments. These arrangements form different port area patterns for different appli-cations and heat release. Operation with venturi mixer or atmospheric injectors is recommended for efficient supply of air-gas mixture to the ribbon burner.
