GAS BURNER FOR DRIER

摘要

PURPOSE: A gas burner of a drier is provided to burn gas completely by increasing the secondary air inflow to the flame with dividing flames, and to stabilize flames by preventing backfire and lifting of flames with shortening the length of flames through the flame holder. CONSTITUTION: A gas burner for a drier is composed of a gas nozzle receiving and injecting gas; a mixing pipe(24) mixing gas from the gas nozzle with primary air; an igniter installed in the outlet of the mixing pipe to ignite gas mixed with primary air from the outlet of the mixing pipe; and a flame holder(760) installed in the outlet of the mixing pipe and composed of flame holes(763) burning gas mixed with primary air with branching and ejecting. The flame holder has an annular hub including a central round flame hole and plural flame holes arranged circumferentially, and plural blades arranged around the hub.
