Modernization of thermal circuit of kilns
Objective
Replacement of six smoke exhausters (including those manufactured by Fläkt Woods) of kilns, in order to increase the flow rate of the coolant supplied to the drying zone. Increasing the output and pressure while maintaining the overall and connection dimensions, with the existing foundation to be reused for installation. Enhanced wear resistance due to the exclusion of cyclones in front of the forced-draft fan. Temperature of handled medium may reach up to +450 °C.
New aerodynamic configurations were developed and tested to solve these issues. Advanced technologies were used to protect the equipment against abrasive wear.
Result
The forced-draft fans were put into operation in 2021-2022. The above-defined objective of increasing the flow rate of the coolant supplied to the drying zone was achieved.
