Measurements in the grate firing system
The grate firing system
The grate firing system consists of a horizontal moving grate for wood chips and other solid biomass. The maximum thermal power output is 240 kW. The fuel feeding from the fuel storage is managed by two stokers.
The primary air is splitted in two different zones to improve the combustion.
The secondary air is splitted in three controlled stages. With this multiple air staged injection it is possible to reduce the NOx emissions considerably.
With 16 ports for portable suction probes the temperature and the gas composition can be determined everywhere in the combustion zone. The exhaust gas composition can be measured synchronously.
