The coal carbonisation station has been designed like a pilot coke oven battery. It enables the quick production of a coke sample from a battery charge, and in combination with the CRI/CSR station, it is a tool that makes it possible for process engineers to develop an optimum composition of the coal mixture before tests on an industrial scale. The station can be used in everyday quality control of coal deliveries or for developing and testing the composition of completely new mixtures.
The parameters of the coke produced on a laboratory scale are similar to the those of the coke produced in the battery.
The station includes:
The production of samples involves the carbonisation of coal weighing from 4 to 5 kg. A sample with grain size of < 3 mm is placed in a steel retort and compacted until a density ranging from 850 to 1000 kg/m3 is reached. The sealed retort is placed in an electric furnace and heated up for several hours. The process temperature is controlled within a range of 800 to 1000°C. The process is divided into stages (up to 10 stages). Each stage can be freely programmed by the user, in terms of temperature increase, level and decrease, as well as duration. The reaction gases generated during the process are discharged and can be reheated in a chamber placed outside the room.
