Claims

[Claims for Utility Model Registration] 1. A small-diameter inner cylinder is disposed inside the outer cylinder through an air passage that is ventilated by a blower, and a primary air inlet that communicates with the air passage is provided at the rear of the inner cylinder. At the same time, a variable flow rate atomizer for liquid fuel is installed at the rear of the inner cylinder with the spray nozzle on the front side, a swirler is installed on the front side of the spray nozzle, and the inner cylinder on the front side of the swirler is installed. In a liquid fuel combustion device in which the front part of a burner is attached to the side wall surface of a combustion chamber, the front part of a burner is provided with a plurality of rows of a plurality of secondary air inlets opened in the inner circumferential direction of a cylinder,
A tertiary air chamber is formed on the outside of the side wall surface, and a plurality of tertiary air inlets are provided on the side wall surface, and tertiary air is provided in the outer cylinder of the burner so that the tertiary air chamber and the air passage communicate with each other. A liquid fuel combustion device characterized by having a supply port. 2. The liquid fuel combustion apparatus according to claim 1, wherein a plurality of tertiary air inlets are provided on a side wall surface above a mounting portion of the burner. 3. A water heater comprising the liquid fuel combustion device according to claim 1 or 2. 4. A bathtub with hot water supply provided with the liquid fuel combustion device according to claim 1 or 2.
