AI Technical Summary

Problems solved by technology

The main reason is that the calorific value of coal gas is lower than that of natural gas or heavy oil, and the melting point of alkali-free glass is high, so that the melting temperature cannot meet the requirements, and the homogenization is not good. Not available

Embodiment Construction

[0041] The present invention will be further elaborated below in conjunction with specific examples.

[0042] The main raw materials include quartz sand, wax stone, boronite, limestone and boric acid, respectively 1.7%, 54.5%, 18.1%, 20.1%, and 2.6% of the total amount of ingredients; small materials include fluorite, compound clarifier, nitric acid Ammonium is mixed with 1.7%, 0.3%, and 1% of the total amount of the total amount of ingredients and mixed with the main raw materials after premixing, and then sent to the horseshoe-shaped kiln by the feeder, feeding 500kg at a time, and feeding once every 20 minutes . The melting area of ​​the horseshoe kiln is 35.75M 2 . Choose lump bituminous coal with a calorific value of 7500kcal / kg, and produce gas from an ordinary gas generator with a calorific value of 14500kcal / m 3 , the coal gas enters the gas regenerator, the air enters the air regenerator, the preheated air and gas enter the empty coal mixing chamber at a ratio of 3...

Abstract

The method of producing non-alkali glass bead with generating furnace gas as fuel includes producing gas of heat value greater than 1400 kcal / cu m with lump coal of heat value greater than 7000 kcal / kg as fuel, and producing non-alkali glass bead with selected glass material and proper technological parameters. The said method has production cost 28 % lower than that with natural gas as fuel and40 % lower than that with heavy oil as fuel.

Description

1. Technical field [0001] The invention relates to the field of inorganic non-metallic materials, and further relates to a method for manufacturing glass spheres. 2. Background technology [0002] There are two ways to produce glass fiber, one is the pool kiln wire drawing method, and the other is the glass ball wire drawing method. The glass ball drawing method is to manufacture glass balls by the kiln method first, then melt the glass balls by the crucible method, and then make glass fibers by wire drawing. At present, natural gas or heavy oil is used as fuel to produce glass spheres by kiln method. Fuel cost accounts for 50-60% of the production cost of alkali-free glass spheres, and other costs account for 40-50%, and the possibility of reduction is not great. Therefore, in order to reduce the production cost, the non-alkali glass sphere manufacturers can only find a breakthrough in fuel, trying to use cheap producer gas as fuel instead of natural gas or heavy oil. Sin...
