Energy-efficient furnace for basalt fiber production

Abstract

AnnotationIn recent years, the production of products made of composite materials based on carbon fiber, glass fiber, and basalt fiber has been developing. Composite products based on continuous basalt fiber are becoming more and more widespread, since basalt is practically an inexhaustible raw material and is actually prepared by nature for use. This article suggests the design of a melting furnace, since the melting process is the most energy-intensive in the production of fiber. The article provides a list of heat engineering principles necessary for creating an energy-efficient furnace, such as the maximum heating of basalt by waste gases, Gorenje fuel directly in the basalt melt and the organization of the melt barbatage, heating of the gas-air mixture and the use of vacuum in the melt clarification zone. This paper presents the results of a demonstration study on physical models showing the operation of the bubbling layer, the saturation of the melt with gas bubbles, and the process of removing visible gas inclusions. The final part of the article presents the results of evaluating the performance and energy costs in the developed furnace.
