The solid component in the high-temperature state is fed to a combustion furnace 2. Gas leaving the dust collector 3 is fed to the partial condenser 4 for tar to partially condensate a heavy tar component and a light tar component. Unseparated gas is stored in a gas tank 5 as a product.

Title: Gas detector and its manufacture
Inventor: FURUSAKI KEIZO
IPC: G01N27/12
Filed: 1986-09-05
Abstract: PURPOSE:To reduce the resistance between a gas sensing layer and an electrode and to perform finer control by providing a diffused layer between the gas sensitive layer and electrode. CONSTITUTION:A ceramic laminate plate 18 is laminated on a ceramic substrate 12 and the electrode pattern 16 of electrodes 16a and 16b for detection, a heat resistance electrode 16e, etc., and united with the substrate 12, and has a window part 18a. Further, the gas sensing layer 21 is so charged in the window part 18a through the diffused layer 20 as to cover the electrode patterns 16a and 16b for detection. The diffused layer 20 is formed by diffusing atoms having a larger valence than gas sensitive transition metal in the crystal lattice of a gas sensitive transition metal oxide. Further, spherical granulated particles 22 are dispersed between the substrate 12 and gas sensitive layer 21 to prevent the both from separating from each other and a coating layer 24 formed of Al2O3 is laminated on the gas sensitive layer 21. Then, the atoms having the larger valence than the transition metal serve as donors for electrons, so the electron conductivity of the diffused layer 20 is improved, so the diffused layer 20 reduces the energy barrier between the electrode and gas sensitive layer. Consequently, the migration of electrons between the electrode and gas sensitive layer is facilitated.
