流体加熱用ヒーターも製造されているが、流体の温度を
２００℃以上にすることはできなかった。However, these heaters have a small contact surface area with the fluid, making it difficult to raise the temperature of a large amount of fluid uniformly and efficiently. Furthermore, fluid heating heaters formed into a honeycomb structure using a material having a large positive temperature resistance coefficient, such as barium titanate semiconductor, have been manufactured, but it has not been possible to raise the temperature of the fluid to 200° C. or higher.

０〜９９％でその平均気孔径が０．１〜５ｍｍであるカ
ーボン基材からなる。° ゛'s fluid heating heater has a three-dimensional skeleton structure and has a porosity of 9.
It consists of a carbon base material having an average pore size of 0.1 to 5 mm in 0 to 99%.
そして好ましくはカーボン基材にはＳｉＣがコーティン

ある。ざらに空隙率が９９％より大きいとカーボン基材
の強度が下がる点で問題がある。Furthermore, if the porosity is less than 90%, the surface area in contact with the fluid is small, and there is a problem in that the temperature of multiple suspended fluids cannot be raised uniformly. If the porosity is more than 99%, there is a problem in that the strength of the carbon base material decreases.
平均気孔径が０．１ｍｍより小さいと、流体の流れが悪
くなるの点で問題がある。さらに平均気孔径が５１より
大きいと、カーボン基材の強度が下がる点で問題がある
。If the average pore diameter is smaller than 0.1 mm, there is a problem in that fluid flow becomes poor. Furthermore, if the average pore diameter is larger than 51, there is a problem in that the strength of the carbon base material decreases.
この発明の流体加熱用ヒータは３次元骨格構造であるた
め、流体との接触表面積が大ぎく、多聞の流体を均一に
効率よく昇温できる。Since the fluid heating heater of the present invention has a three-dimensional skeleton structure, the surface area in contact with the fluid is large, and the temperature of a large amount of fluid can be raised uniformly and efficiently.

グすれば耐酸化性が良好になる。A fluid heating heater made of a carbon base material can be used, for example, as a fluid heating heater for a combustion burner. The porosity of this carbon base material is 95%, and the average pore diameter is 2.5 mm. Preferably it is coated with SiC. For example, the thickness of the coating layer at this time is 100 μm. Coating like this will improve oxidation resistance.

カーボン駐材となる。A resin (for example, furfuryl alcohol polymer) is attached to porous soft urethane with a three-dimensional skeleton structure, and this resin is inserted into the holes in the urethane. Thereafter, the resin is cured by polycondensation, and then fired at 950° C. in a non-oxidizing atmosphere (for example, a nitrogen atmosphere). By this firing, the urethane is carbonized and burnt out, and the resin becomes a glass-like carbon parking material with a three-dimensional skeleton structure.
