New pulverised-fuel firing concept for minimum emissions under extreme operating conditions at Altbach/Deizisau Power Station, Neckarwerke Stuttgart AG

摘要

The new of firing concept, combining for the first time vortex burners with a rotational flow in combustion chamber, yields very low emission values. The furnace walls are excellently protected against corrosion by a reducing atmosphere. Introduced are being development steps of the firing concept arid of the likewise newly developed staged mixed homer. The good operating experience gathered is being described. Simulation calculations of the flames and of the furnace are being compared with detailed measuring results.
