Liquid fuel oil gasifier head

Abstract

This utility model discloses a liquid fuel oil gasification burner head, including an outer shell, an inner liner, a multi-layered sleeve-type gasification core, and a high-pressure ignition needle. The inner liner is nested inside the outer shell to form a U-shaped annular sealed space, and the inner liner wall is provided with upwardly inclined air injection holes. The core is vertically arranged at the center of the inner liner and consists of an inner thin tube, a middle coarse tube, and an outer conical sleeve, forming a two-stage oil passage: the inner thin tube and the middle coarse tube form a first oil passage, and the outer conical sleeve and the middle coarse tube form a second oil passage. An oil outlet is opened at the bottom of the outer conical sleeve, and the tube wall is provided with upwardly inclined air holes. The tip of the high-pressure ignition needle is directly opposite the oil outlet. The technical solution of this utility model can extend the heating path of fuel oil through the multi-layered sleeve, realize the complete gasification of high / low flash point fuel oil (such as ethylene glycol, light white oil, alcohol-based fuels, etc.), and solve the problems of traditional burners not being able to achieve small-flame combustion, incomplete combustion, and black smoke after ignition and shutdown.
