Optimisation of a mineral wool production process

Mineral wool, produced e.g. from basalt, is widely applied as material for thermal and acoustic insulation. Figure 8.2.1 gives an overview of the technological process of mineral wool production [50]. The basalt rock is dosed into a furnace, where it is melted by means of natural gas combustion. The basalt melt (lava) is introduced into a wool production unit. Here, the lava is poured onto the periphery of disks of high speed of revolution (Figure 8.2.2). Basalt lava film is formed on the periphery of the disks. According to centrifugal and Coriolis forces, basalt droplets protrude from the film and detach from the disks, hauling basalt filaments along. The multitude of these basalt filaments is known as basalt wool. The portion of basalt lava not utilised for wool formation falls into the garbage removal unit. The wool is forwarded from the wool production unit to the settling chamber by means of high-velocity air jets emitted from nozzles located at the periphery of the disks (Figure 8.2.3). In the settling chamber, the wool is settled by means of air sucked through the channels located at the bottom of the chamber. The wool layer is then forwarded for further processing.

This lecture note aims at providing basic information on nowadays applied fluid flow measurement techniques, in terms of their operating principle, layouts, application areas, advantages, and limitations. As such, it intends to give an aid in decision-making when selecting instrumentation for the solution of various practical flow measurement problems, also providing hints for the actual realisation of the measurements.
