The key technology of applying low grade coal is to increase secondary air temperature, ensure sufficient air in kiln and adjust the batching scheme properly.
Through homogeneous mixing between gas and air in cyclical combustion chamber of gas external combustion type lime kiln, it can be enough combustion, has homogeneous flame temperature.
