Wilhelm Ruhl (born October 23, 1848 in Cassel , † January 3, 1926 in Berlin ) was a German engineer and inventor of Ruhl's pulverized coal combustion .

Life

William Ruhl studied at the Commercial Academy Charlottenburg Engineering and joined at the beginning of the winter semester 1868/69 the Association of Saxony, later Corps Saxonia-Berlin, at. After graduating, he worked as an engineer and later as a senior engineer. Among other things, he developed a process for pulverized coal firing, which, after his person, went down in the specialist literature as Ruhl's pulverized coal firing. He was granted a patent for this invention under the D.RP. No. 85511 granted.

Ruhl first tested his new process in a test facility at Bretschneider & Krügner before it was first successfully applied on a large scale under the supervision of the A. Borsig mechanical engineering institute in the Berlin Opera House.

His method was not only mentioned in specialist articles, but also in contemporary editions of general encyclopedias such as Brockhaus' Konversations-Lexikon or Meyer's Großes Konversations-Lexikon.

Essential features of Ruhl's pulverized coal combustion

Ruhl's pulverized coal firing is characterized by the loosening of the coal dust by means of screw conveyors, regulation of the amount of coal dust by means of sliders, conveyance of the coal dust together with the combustion air into the combustion chamber through the natural draft of the chimney, i.e. without additional drive power, and regulation of the amount of combustion air by raising or lowering it the ceiling of the air shaft via a lever mechanism.

In addition to the general advantages of pulverized coal firing compared to conventional coal firing, especially the lack of smoke, the specific operating costs of heating in the Berlin opera house could be reduced by more than 22%.
