Abstract: An electric heater to heat a flow of a fluid having a jacket block comprising a plurality of longitudinal bores to allow the through-flow of a gas phase medium. An elongate heating element extends through each of the bores and is positionally stabilised relative to the jacket block via at least one support member, optionally in the form or an elongate rod to inhibit undesirable independent axial and/or lateral movement of the heating element relative to the jacket block.

Abstract: A molybdenum disilicide-based ceramic heating element holding structure includes a holding member that is attached to a base portion and that holds an elongated support member, for mounting a molybdenum disilicide-based ceramic heating element of an elongated shape at intervals in a long axis direction thereof. The molybdenum disilicide-based ceramic heating element mounted on the support member can be exchanged without breaking the holding structure. A plurality of elongated support members can be provided, and a U-shaped portion of an elongated molybdenum disilicide-based ceramic heating element having a meandering shape can be inserted and extracted from a uniaxial direction in a space partitioned by the base portion. The plurality of support members and the holding member holding the plurality of elongated support members are detachable and the support member is removable from the holding member.

Abstract: A heating apparatus, which can stably fix a heater and be easily produced, includes a heat insulating material and an electric heater embedded in the surface or near the surface of the heat insulating material. At least one hook extends from the electric heater into the heat insulating material. The heat insulating material is formed of ceramic fibers and a binder binding the ceramic fibers, and is integrally molded with the electric heater having the hook.
