enrichment air in shaft kiln

Shaft Furnace

The combustion air which may be preheated, is introduced via tuyres placed all round the lower end of the shaft a short distance above the "hearth" or "crucible", in melting furnaces. The iron blast furnace ( Fig. 47 ) is the most highly developed shaft furnace and can operate very efficiently not only as a heating unit but as a high temperature reaction chamber. Get price
