Computation and comparison of two electric air heaters for industrial use

Resumo

The computational results of temperature on the surface of ribbed tubular electric heaters and ribbed pipes of thermosiphons have been presented, the desired airflow rate, and installed electric capacity of fan motors for existing and developed electric air heaters has been determined. The computational results of the temperatures of the ribbed pipes have been compared with the experimental data. The novelty of the development has been confirmed by patents obtained on the invention of the electric air-heater design.
