Appletons' cyclopaedia of applied mechanics: a dictionary of mechanical engineering and the mechanical arts . tre of each kiln to the chimney-shaft, dampers MM be-ing fitted to each flue to open or close communicationbetween the kilns and chimney, as may be systems of continuous kilns for burning bricks,tiles, etc., have come into practical use:the French system of Colas, also knownas that of Borie, and the German systemof Hoffmann, the well-known annularkiln or Ringofen. (See Brick-makingMachinery.) The Colas principle con-sists in placing air-dried bricks on smallrailway trucks forming a long train ; thisis slowly moved through an arched cham-ber, provided in its centre with fixedfireplaces for burning the bricks; thefire in these kilns is stationary, whilethe bricks are moved forward. The principle of the Hoffmann kiln is just the reverse; here the bricks are stacked inan annular burning-chamber, and remain stationary while the fire travels through.
