Problems solved by technology

However, liquid fuel needs to temporarily vaporize the sprayed fuel, so, especially at low temperatures, the liquid material will have ignition retardation and rapid combustion, and incomplete combustion and carbon build-up on the furnace wall (furnace wall) (especially Defects such as adhesion on the inner wall of the primary combustion chamber)

Embodiment Construction

[0033] Hereinafter, embodiments of the present invention will be described with reference to the drawings. figure 1 A diffusion combustion device 1 according to one embodiment of the present invention is shown. The diffusion combustion device 1 is formed on the furnace wall 3 defining the main combustion chamber 2 . The diffusion combustion device 1 has: a primary combustion chamber 4, which is formed on the furnace wall 3 as a recess opening on the main combustion chamber 2; a guide burner 5, which forms a flame as an ignition source in the primary combustion chamber 4; A fuel nozzle 6, which injects fuel into the main combustion chamber 2 through the primary combustion chamber 4; a primary air supply path 7, which is formed by a pipe embedded in the outside of the fuel nozzle 6, and supplies primary air around the fuel nozzle 6; A plurality of secondary air supply channels 8 (only one shown in the figure), which can inject secondary air into the main combustion chamber 2 fr...

Abstract

To provide a diffusion combustion burner capable of using liquid fuel, in a diffusion combustion burner 1 comprising a primary combustion chamber 4 opened to a main combustion chamber 2; a pilot burner 5 provided in the primary combustion chamber 4; a fuel nozzle 6 injecting fuel into the primary combustion chamber 4; a primary air supply channel supplying primary air to around the fuel nozzle 6 along the fuel nozzle 6; and a secondary air channel 8 injecting secondary air into the main combustion chamber 2 from a position proximal to the primary combustion chamber 4, there is provided a primary air ratio adjusting means which make higher the primary air ratio that is the ratio of the amount of the primary air to the whole amount of the primary air and the secondary air when the temperature of the main combustion chamber 2 is low, and make lower the primary air ratio when the temperature of the main combustion chamber 2 is high.

Description

technical field [0001] The invention relates to a diffusion combustion device. Background technique [0002] Patent Document 1 discloses a diffusion combustion device, which is a diffusion combustion device that directly injects fuel and air into a combustion chamber and burns them. The primary combustion chamber directly injects fuel and primary air, and injects secondary air from near the primary combustion chamber to the main combustion chamber. [0003] In addition, Patent Document 2 discloses a diffusion combustion device in which a secondary air supply path and an exhaust gas discharge path are operated alternately (alternating operation), and heat accumulators are arranged respectively. [0004] The aforementioned regenerative type diffusion combustion device is practical for gas as a fuel, but not practical for liquid fuel. In particular, a combustion device with a large combustion capacity is in great demand for the use of heavy oil as a fuel. However, liquid fue...
