Products for Domestic Biomass Combustion

In simple wood stoves, there is normally no fan, so the catalytic converter must not cause a significant pressure drop. Another consideration is that ash will be present, which could block the channels in the catalytic converter. For these two reasons, it is best to specify one based on a honeycomb substrate with a low cell-density, for example 18 or 25 cells per square inch.

The flue gas temperature in appliances which burn logs can vary significantly, which means that a substrate which can act as a heat store is preferable. In this respect, ceramic honeycombs are better than metal ones.

More sophisticated domestic biomass heating appliances incorporating fans to drive air through the catalytic converter may utilise reticulated foam substrates. Metal substrates can also be suitable but when using any substrates which ash cannot pass through it is necessary to include some means to prevent the ash from reaching them.
