Hybrid techology of flue gas denitrification system. Part 1—Preliminary studies of flow turbulence and pressure drop in the elements of rotary air heater baskets

The paper presents the results of physical and numerical tests of fluid flow through the filling of a rotary air heater (RAH). A laboratory-scale test bench was used to measure flow resistance across a fragment of a RAH. Seven types of RAH modules were tested - one steel and six ceramic (as catalyst carriers). The relationship between pressure drop and velocity (Re number) of flow was used to deduce the flow characteristics for each of the RAH...
