A vaporizer includes an atomizer, a vaporizer body, and a heating portion. The heating portion includes an inner heater block and an inner heater. An inner tube is made of a heat-resistant glass and has an outer diameter smaller than an inner diameter of the hollow vaporizer body. The inner heater block includes division pieces obtained by dividing the inner heater block along a center axis thereof and an elastic material. The elastic material is disposed between the division pieces and acts so as to press and urge the division pieces in separation directions and press them against an inner peripheral surface of the inner tube. The inner heater is embedded in each division piece.

Various embodiments disclose a glow plug for a solid oxide fuel cell system. The glow plug includes a housing having a first end portion and a second end portion. The glow plug includes a heating element longitudinally disposed in the housing, extending from the second end portion of the housing towards the first end portion and extending outwardly from the housing for igniting fuel. Further, the glow plug includes a pair of coiled wires electrically connected to the heating element. Further, the glow plug includes a potting compound disposed within the second end portion of the housing for securing electrical coupling of the pair of coiled wires with the heating element. Furthermore, the glow plug includes a sealing element configured to form an air-tight connection between the housing and the heating element. The sealing element is positioned on top of the potting compound.

An electronic cigarette burner element has a heating wire, a porous ceramic matrix, and outer cover, holes in the outer cover, and a ventilation air passage through the porous ceramic matrix. The heating wire is configured to heat and atomize vape oil. The heating wire is formed with a coil and a pair of leads including a first lead and a second lead. A porous ceramic matrix encapsulates the coil of the heating wire. A heating body is formed when the heating wire is encapsulated by the porous ceramic matrix. An outer cover can be made of metal and can fit over the heating body. A hole is formed on the outer covet to receive vape oil. The vape oil wicks through the porous ceramic matrix like a sponge receiving water. A ventilation air passage is formed along a surface of the porous ceramic matrix.
