Experimental lime kiln for small scale production of lime binders

A small scale lime kiln was designed and built in order to evaluate production of historic lime binders. The kiln does not copy any specific historic model. It is designed to simulate variety of “traditional” lime calcination procedures. The construction of the kiln is presented in details. The prototype is equipped with sensors and the burning process is monitored by a set of thermocouples in three levels, air flow on the air inlet and composition of emissions (CO, CO2 and O2). The obtained data are used for assessment of the whole burning process and its optimisation
