This ensures that virtually of the energy is transferred to the perlite sand and that none of the hot process air is released to the atmosphere. The expansion furnace contains no moving parts so wear is minimal. Only the exposure to high temperature must be taken into account. The different heat expansion rates of the materials used is ...

A thermally efficient process for the expansion of perlite ore is described. The inlet port and burner of a perlite expansion chamber (preferably a vertical expander) are enclosed such that no ambient air can enter the chamber. Air and fuel are metered to the burner with the amount of air being controlled such that the fuel/air premix contains at least enough air to start and maintain minimum ...

Perlite is an igneous mineral composed by silicon, aluminum, oxygen and water. It can be expanded by heating it up at temperatures above 870 °C, then it becomes plastic, and the steam formed inside pressures out of the mineral. Maximum expansion is possible if the particles are heated up quickly, since the expansion degree strongly depends on the remaining water in the particles at the time ...

typical expansion process consist in pouring the particles in rotary kilns operated with natural gas, but it is proposed in this research that the particles can be heated quickly with microwaves at 2.45 GHz. Particles of 0.08 cm and 0.018 cm of average diameter were expanded 10 to 20 times. Keywords: Microwaves, perlite, expansion, heating. RESUMEN

Jun 01, 2014· The obtained results will be discussed in the economic evaluation section of the results and the discussion part of this article. The energy efficiency of the control volume is defined as (33) η = ∑ output E ̇ ∑ input E ̇ The energy efficiency of the new perlite expansion furnace was determined to be 69%. 2.2.3. Exergy balance

Energy efficiency of the perlite expansion furnace was determined as 66% in this study. By comparison, exergy efficiencies of the furnaces change between 40% and 50%,,, but exergy efficiency of the perlite expansion furnace was determined as 26%. When the perlite expansion furnace is compared to other furnaces, both energy and exergy ...

The expansion process also creates the perlite's white colour – which is one it's most distinguished characteristics. While the crude perlite rock may range from transparent to light grey to glossy black, the colour of expanded perlite ranges from snowy- to greyish white. Expanded perlite can be manufactured to weigh from 32 kg/m3 to 240

BUBLON® SPHERES are manufactured using a patented, energy-efficient process and are optimized to meet your individual requirements, for use in a wide range of applications, for example, in the building materials, plastics and coatings industries.

A computational code has been developed based on a Eulerian–Lagrangian approach in order to model the combustion and the motion of perlite particles in a vertical expansion furnace. The expansion of a single particle, which takes place during its motion in the furnace, has been modeled by taking into account the perlite chemical composition and the gradual variation of the temperature ...
