Boiler using microwave

PURPOSE: A boiler using microwave is provide to prevent an environmental contamination by the combustion, save an energy by a microwave. CONSTITUTION: A boiler using microwave comprises: an inner/outer containers(12,11), an inner and outer heating cases(14,13), a heat insulating material(21), a magnetron(31), and a wave guide pipe(32). The inner container is located in an inner side of the outer container. The inner heating cases are located in the inner side of the outer heating cases. The heat insulating material fills between the inner and the outer container and secludes heat leakage to the outside. The wave guide pipe transfers a heating element(24) the microwave created in the magnetron. The microwave delivered through the heating element and collided and reflected.
