Abstract

Official abstract text for this publication.

A combustion device for a melting furnace, capable of heating a melting target object and the ceiling portion of the furnace with the radiant heat of the flame, including a combustion space above the location of the melting target object, including a fuel injection nozzle having a plurality of fuel injecting portions, which portions include orifices disposed side by side horizontally relative to the direction of fuel injection, and formed side by side vertically relative to the same. The orifices are formed radially side by side as seen laterally, with a direction along a middle angle in the angular range between the fuel injection direction of the uppermost fuel injection orifice and the fuel injection direction of the lowermost fuel injection orifice being directed obliquely upwards. The fuel injection orifices of the upper fuel injecting portion are formed radially side by side as seen in the plane view.

First claim

Opening claim text (preview).

The invention claimed is: 1. A melting furnace for glass raw material comprising three or more combustion devices, each combustion device comprises; a fuel injection nozzle for injecting gas fuel to a combustion space above a melting target object as a glass raw material located in a melting tank for melting a glass raw material is configured to inject the gas fuel from a lateral portion of the combustion space; and a combustion air feeding portion for feeding combustion air alo…
