Description

Build detail and engineering notes

A heater is judged by what happens ninety seconds after water hits the stones. Thin stone beds give a sharp burst and then a cold room; the E90 carries 60 kg of split olivine diabase, enough thermal mass to absorb four or five ladles without the air temperature falling away.

Elements are Incoloy 800, staged in three banks so the controller can hold a set point rather than swinging around it.
