Show I AN IMPROVED STEAM ENGINE I The Baltimore Sun gives a description of a new improvement of the steam en glue ns shown by l Prof E Jones head of the mechanical laboratory of the Royal Technical high school at Char UHtenburg The ordinary simple high about pressure engine gets out of the coal 5 per cent of the theoretical power produced by It combustion Compound engines In which the steam passes successively through two three or fOtr cylinders produces under the I best conditions about 12 ilons or 13 per cent of tho fuel energy This has been sup Slp posed to be the lust word Io on steam steam engines en-gines the limit of possible efficiency having Jt was supposed been fully ul reached But the claim Is clalm that the now engines invented by Behrcnd of Ham burg and Zimmermann of Ludwig haven increase C the power of tile best engine by Ocr onehalf As described by Consul F H Mason of Berlin in adAahce sheets of Consular Reports February 2Clh the Improvement con sists In utilizing the heat left In thc waste steam to evaporate sulphurous acid for a supplementary engine As sulphurous acid has a lower boiling point than water the heat of the waste steam suffices to vaporize the acid and Ihe Vapor acting against the piston of another cylinder produces another in stallment of power After leaving tho cylinder the sulphurous acid vapor passes through tubes < iiv > nohr i m > vt 1VI1II cold water to be condensed and Is then j pumped back to be vaporized the same acid being used over and over agoJn In I definitely The cost oC the new device Is simply the cost of the supplementary j I engine with Ils Initial supply of sul I rlimnip nold j |
