Gasification device for gasification combustion fireplace

Abstract

A device includes a chamber, a lid, heating elements, a base, and a controller. The chamber is a structure containing a inner cavity, the base is below the chamber, and the heating elements are between a lower surface of the chamber and the base. Cooling fins are in the inner cavity connected to a lower surface of the inner cavity and are close to the heating elements. Channels for liquid circulation are provided between fins and between the fins and an inner wall of the chamber. The lid is above the chamber and seals the inner cavity so that the inner cavity is closed. Gas outlet ports are on the lid. Due to the cooling fins, when the heating elements heat liquid fuel in the inner cavity, the liquid fuel is heated uniformly, and the gasification process is stable and controllable, avoiding explosive boiling of the liquid fuel.
