Optimising fuel flow in pulverised coal and biomass-fired

Optimising fuel flow in pulverised coal and biomass-fired

Fuel flow imbalance is commonly addressed by changing pipe-to-pipe airflow with variable or fixed orifices in the coal pipes Orifices add a non-recoverable pressure loss to the coal pipe which results in a decrease in flow through the pipe Coal flow balancing with orifices is quite effective if the fuel flow
