ABSTRACT:
This invention relates to a kerosene vapor stove with an automatic fuel feeding system. There are two ways of vaporizing the kerosene. When the stove is about to be lighted, kerosene is channelled into a preliminary preheating tube to be heated up to a high temperature within a short time. The heated kerosene under pressure passes through a nozzle and shoots through an air gap into a mixing tube, vaporizing in the process. The mixture of the kerosene vapor and air is delivered into a burner where it burns. After the stove has been lighted for about two minutes, the loop of tube above the burner will be well heated. This tube is a part of the normal path for kerosene. Kerosene is now channelled through this tube for preheating, utilizing the heat produced by the burner to effect vaporization. The automatic feeding of the kerosene is accomplished through using a steel container containing kerosene up to 80% of its volume. A tube extends from the outlet valve of the container down to its bottom. Compressed air is stored in the upper portion of the container to exert a pressure on the surface of the kerosene which will be forced out of the container into the stove when valve at the top of the kerosene container is turned on.
