High temperature combustion method of sulphur in fuel has been studied.<BR>Using improved JIS method, heavy oil and gasoline could be burned within 15 minutes without explosion.<BR>Sulphur in coal, coke, heavy oil and gasoline could be analysed using same apparatus and analytical precision is high, furthermore there is no bias for certified value of standard samples.<BR>And also combustible sulphur in coal could be analysed by this method.<BR>Improved method is based on next procedure, that is, silica tube keeps the boat within is inserted into porcelain combustion tube passing oxygen gas continuously and a gap of both tubes is sealed.<BR>And heating temperature for boat is changed depend upon kind of sample and helium gas is introduced through silica tube for five minutes and carring volatile matter into burning zone of 900°C in porcelain tube, then the boat is moved to 900°C zone and helium gas is exchanged to oxygen gas and thus combustion is completed.<BR>Gas produced by combustion is introduced into the absorption bottle after passing the 1350°C zone.<BR>Then sulphuric acid in the solution is determined by alkalimetry.
