VEIK – Improvement of heat treatment and heating in industrial furnaces by new innovative ceramic hot gas fans

Background

  • Usage of metallic fans in thermoprocessing plants is limited to approx. 600 to 800°C.
  • Two types of furnaces are necessary for heat treatment, one for temperature values up to 800°C and one for above 800°C.
  • In the case of stacked goods in the funace, locally strongly varying heating at over 800°C.

Objectives

  • Development of a ceramic fan for high temperature region.
  • Targeted circulation of oxidising atmospheres in thermoprocessing plants at temperatures of 400°C up to 1.200 °C.
  • Lowering of fossil fuel demand and CO2 emission.

Innovative content

  • Development of a SiC fan impeller by additive manufacturing.
  • Construction of a fan for circulation up to 1,200°C.

Potential benefits for the industry

  • Lowering process time for heating and heat treatment processes and thereby lowering of CO2 emissions.
  • Reduction in the number of necessary thermoprocessing plants by more flexible usage of individual plant.
  • Improvement of product quality by more homogenous heating.
