Process for utilizing waste heat and for obtaining water gas during the cooling of incandescent coke
A process for utilizing waste heat and for obtaining water gas during the cooling of incandescent coke ejected from a chamber oven is described, this process being in two stages. In the first stage, the coke is dry-cooled with a mixture of water gas and water vapor as the cooling gas. This is circulated, and from the circuit the desired waste heat and the desired water gas are extracted. In the second stage, the coke is wet-cooled with water. The water vapor formed is taken off and returned to the environment and/or to the second stage. An apparatus is described for carrying out the process, and this apparatus has, located under one another, a filling shaft (1), a pre-chamber (2), a cooling chamber (3), a quenching chamber (4) with a water-spray device (5), an extraction housing (6) and a discharge shaft (7), and is equipped with a cooling-gas discharge line (19) leading away from the cooling chamber (3) and, in succession, a coarse separator (20), a heat sink (21), a blower (23), a cooling-gas delivery line (25) to the cooling chamber (3), an extraction line (26) leading away from the cooling-gas delivery line (25) with a throttling device (27), and a take-off line (34) which leads away from the extraction housing (6) and which leads to a cyclone separator (35), a blower (36) and an exhaust steam pipe (38) with a throttling device (37) and/or to a return line (39) with a throttling device (40).
