Stroke height for gas production from briquettes
Thread Content
Question: When using coal sticks to produce gas, is it better to have a high or low carbon layer height? Does the height of the carbon layer affect the gas composition, such as methane?
May I ask the original poster: is the process used to produce gas from coal rods the Ruhr process?
The control of the specific void space requires consideration of the height-to-diameter ratio of your furnace; of course, this is not the only factor. The actual control methods depend on the specific circumstances. As for methane, it is necessary to take into account the control of furnace temperature, because methanation reactions can only occur at a certain furnace temperature
The height of the carbon layer is determined by factors such as the capacity of the fan, the properties of the raw material, and the level of load. It is necessary to ensure both the heat storage capacity of the raw material layer and the fact that the resistance posed by this layer does not become too high. The mechanical strength and thermal stability of briquetted coal are inferior to those of lump coal, and the resistance of the raw material layer is relatively higher; when switching from lump coal to briquetted coal, the height of the carbon layer needs to be reduced appropriately.
