<p>In glass production, waste gases usually occur which, although they are normally used for preheating the fresh air for a glass-melting furnace, still have a residual temperature of 400-600 DEG C. In order to be able to utilise this residual energy effectively for preheating the raw materials for glass production, in particular glass fragments, the invention proposes leading the waste gases through a hopper (19) for the temporary storage of glass fragments (20) and thereby heating the batch of glass fragments (20) to up to 380 DEG C. The waste gases which are cooled and contaminated during the preheating of the batch of glass fragments (20) are in one proposal of the invention led via a wet scrubber (26) before they are led back into the waste gas duct (17) leading to the stack or the like. <IMAGE></p> |
