13045 Coal Distributor Paper Layout 1

It is not uncommon for fuel balance between coal pipes to vary by 177 30 or more despite having well balanced primary airflow to the fuel pipes Fuel imbalance between burners results in a wide range of air/fuel ratios and heat input across the furnace So-called...

Measurement and prediction of coal flow rates in pulverised fuel pipes

pulverised coal must be delivered controlled and evenly distributed between the PF pipes and to the burners The burners require a controlled flow of air primary secondary and tertiary air fuel mixture with a relatively even coal particle size distribution The...
