The effects of several factor that affects the ignition temperature of solid fuels were measured by using simulated fuel and an air-flow type thermobalance. For the simulated fuel, a mixture of activated charcoal, salicylic acid bentonite was used to simulate the fixed carbon, volatile matter and ash of solid fuels. The fuel could simulate solid fuels with a wide range of component ratios. The newly designed air-flow type thermobalance gave uniform oxygen supply within the fuel layer. The experimental parameters were oxygen concentration (0-100 vol%), gas flow rate (8-300 cm^3/min) and fuel component ratio. Based on the results, it can be concluded that: (1) the ignition of solid fuel is initiated by the ignition in the mixture of volatile matter and air, and there is an optimum volatile matter-air ratio for the ignition, (2) the ignition temperature is estimated by excess oxygen ratio in the fuel layer and oxygen concentration in the feed gas of solid fuel.
