1. A combustion heat generator comprising:
a plate-shaped housing having a combustion space therein;
an oxidant injector provided on a first position of the housing and forming a first circulation region by inputting an oxidant to an outer periphery of an inner side of the combustion space through an oxidant injection nozzle and circulating the oxidant;
a gas ejector provided on a second position of the housing and discharging a portion of gas circulating in the combustion space; and
a fuel feeder installed so that a front end of a fuel injection nozzle is extended into the housing and positioned in a second circulation region formed in a center of the combustion space by circulation of an oxidant in the first circulation region to inject only fuel into the second circulation region,
wherein the first position and the second position are formed on the same side of the housing respectively,
wherein space combustion is generated in the combustion space based on the second circulation region while the fuel injected into the second circulation region is gradually mixed with the oxidant circulating along the first circulation region and diffused into the first circulation region,
wherein a gas recirculation region by the first circulation and the second circulation is formed in the housing and the space combustion is generated based on the gas recirculation region, and
wherein the oxidant and the fuel recirculate in one direction in the housing.
