Abstract

Disclosed is ignition apparatus (6) for igniting particulate fuel, the ignition apparatus comprising an inlet (20) for receiving a fuel-gas mixture comprising particulate fuel and oxygen-containing gas, an outlet (24), and an ignition chamber (18) located intermediate the inlet and the outlet, the ignition chamber being defined at least in part by a first body portion having a first surface and a second body portion having a second surface, wherein the first and second surfaces are opposed and spaced-apart from each other and the ignition chamber is formed and arranged so that received fuel-gas mixture passes between the opposed spaced-apart first and second surfaces, the ignition chamber further comprising heating apparatus (39, 42) operable to heat one or both of the first and second surfaces to above the autoignition temperature of a particulate fuel to ignite a proportion of received fuel particles which contact the heated one or both of the first and second surfaces in use. There is also disclosed a furnace (1) including the ignition apparatus.
