Problems solved by technology

[0002] We know that currently in the glass industry, the fuels used for melting glass in melting furnaces are nothing more than the following types: heavy oil, residual oil or other fuel oil, natural gas, producer gas or coke oven gas. The price of related products continues to rise, which makes the proportion of the above-mentioned fuel cost in the glass manufacturing cost increase significantly

Embodiment Construction

[0014] Below in conjunction with the present invention is further described:

[0015] A solid-liquid mixed fuel for melting glass in a melting furnace, which is formed by mixing petroleum coke powder and fuel oil. The weight percentage of petroleum coke powder and fuel oil is 5%-80% of petroleum coke powder and 20%-95% of fuel oil , the fuel oil used in the present invention can be crude oil, heavy oil, residual oil, coal tar or various animal and vegetable oils, and the present invention replaces coal powder as solid phase in the previous solid-liquid mixed fuel with petroleum coke powder. The reasons are as follows: the average calorific value of our domestic petroleum coke is 2022KJ / kg (8453kcal / kg), and the typical components are 90% carbon; 4% hydrogen; 2.1% nitrogen; 1.9% sulfur; 1.82% oxygen ; 0.18% ash. But usually the ash content in pulverized coal is mostly 8%-20%, and the calorific value of pulverized coal is only 1435-1674KJ / kg (6000-7000kcal / kg). Such a large as...

Abstract

This invention relates to a solid-liquid mixed fuel for glass melting furnace. The solid-liquid mixed fuel is mixed from petroleum coke powder 5-80 wt.% and fuel oil 20-95 wt.%. In addition, according to the weight of the solid-liquid mixed fuel, water less than 30 wt.%, emulsifier less than 3 wt.% and dispersant less than 3 wt.% can also be added. This invention uses petroleum coke powder as a substitute for coal powder in the traditional solid-liquid mixed fuel, thus increasing the content of three-atom gases in the flame, improving the flame radiance, and strengthening the radial heat transfer from the flame to the glass liquid. Besides, the solid-liquid mixed fuel can be used in conventional glass melting furnace, thus having a high profit.

Description

Technical field: [0001] The invention relates to a mixed fuel and its application, in particular to a solid-liquid mixed fuel for melting glass in a melting furnace. Background technique: [0002] We know that currently in the glass industry, the fuels used for melting glass in melting furnaces are nothing more than the following types: heavy oil, residual oil or other fuel oil, natural gas, producer gas or coke oven gas. The rising prices of related products have greatly increased the proportion of the above-mentioned fuel costs in glass manufacturing costs. Invention content: [0003] The purpose of the present invention is to overcome the above-mentioned deficiencies in the prior art, to provide a kind of solid-liquid mixed fuel for melting glass in a melting furnace. Under the premise of reducing pollutant emissions and not increasing the erosion of refractory materials in the kiln body, the cost of fuel is greatly reduced, thereby greatly reducing the manufacturing c...
