The present invention relates to a fixed-bed gasifier using a microwave igniter, capable of directly igniting a low-reactivity fuel, not an igniter requiring the supply of additional combustible fuel, for ignition through microwave emission for ignition of a fixed-bed gasifier for gasification of a fuel having low reactivity. The operation costs can be reduced by performing gasifier ignition without supplying additional ignition fuel. The installation costs can be reduced by not requiring fuel supply equipment which is additionally required for an igniter using the ignition fuel. The operation efficiency can be improved by performing the ignition operation in a state that fuel having low ignitability is charged into the gasifier. The ignition equipment can be operated semi-permanently by emitting microwaves directly to a grate. The fixed-bed gasifier comprises: a fuel supply unit; an oxidant supply unit; a reaction unit; and a gas discharge unit. COPYRIGHT KIPO 2018 ...
