Continuirlicher Brennofen für Kalk und andere Stoffe mit Gas-Generator und Gas-Feuerung
The invention relates to kilns for lime, plaster-of-paris, bricks, glass, and other substances; and the object is to run them continuously, not to bring the fuel in contact with the substances to be heated, but to generate gas from the former, which, by means of peculiarly-constructed regenerators, is heated, and in this hot state mixed with air, which is heated also, to ignite this mixture, and to use the flames thus produced for heating the substances within the kiln.
The object is also to utilise the fuel to its greatest advantage, to obtain the condensable products of the distilled fuel, to burn all carboniferous parts of the lime, plaster-of-paris, etc., and to avoid the smoking of such kilns, which is annoying, and in some instances poisonous, to the neighbourhood.
