Presented here are equations governing heat transfer in a moving-bed heat exchanger, along with a numerical method for solving them Moving-bed heat exchangers (MBHE) represent an efficient method for heating or cooling bulk-solid materials compared to other technologies, such as…
ANDRITZ Separation has been serving industries ranging from petrochemicals and soda ash to agrochemicals for more than a century. What all these chemical applications have in common is the importance of highly efficient thermal separation with either continuous or discontinuous…
Periods of reduced heat-transfer-fluid (HTF) system operation offer opportunities for mechanical integrity engineers to perform necessary maintenance. Here are suggestions for using the downtime for maintenance tasks. Safety These activities support ongoing safety of the HTF unit. Leak repairs. Repair…
An understanding of the available NOx-reduction strategies will help engineers to select the best technique to improve the performance of their combustion processes Pollution due to oxides of nitrogen — frequently abbreviated as NOx — is regulated with varying degrees…
