A large opening at the bottomadmits of the withdrawal of ashes and clinkers thatmay be found in the combustion of the fuel, and ablast of air—which by preference should be heated—is directed into tin:- very heart of the mass of fuel. THE JOURNAL OF THE SOCIETY OF CHEMICAL INDUSTRY. [July 29, im. The result is a very high temperature in trie centre of Fig. -2 is a section of the modified gas producer tlif muss, <me of the essential conditions for the arranged for this purpose, with the addition of the total conversion of coal into combustible gas being a curtain wall A, which comes down to the level of the maximum degree of heat at one portion of the proce . fuel al B, or may extend a little below it, dividing and no heat is lost at that point, which loss would the gas producer intotwo compartments so as nearly. interfere with the due conversion of carbonic acidinto carbonic oxide. At the same time, water, whichis admitted by a continual streamlet near the bottom,is evaporated by the residual heat of the fire andclinkers which is thus utilised, and currents of steamare directed or drawn into the apparatus, passingthrough the zone of highest temperature towards thecentre of the mass. They there become converted bycontact with the incandescent fuel into carbonic oxide,and hydrogen (free from nitrogen), which addto the calorific effect of the gas produced. The modified form of Siemens old-type producer,which is also employed for the purpose of enrichingthe gases by transforming the heavy hydrocarbons,that would otherwise form tar on condensation, isdescribed in a paper read by the authors principalut, Mr. Head, before the Iron and SteelInstitute, in May last, and published in the Journalof the Institute, Part 1 of the volume for 1885. Thegas producer is divided into two compartments, o
