Development of and experience with a new generation of modern coal firing systems in a new high-efficiency combined heat and power station

A new, highly advanced combined heat and power station which links a steam turbine with a coal-fired main boiler and a gas turbine waste heat system with a total electric output of 381 MW was commissioned in the summer of 1997. The main boiler is equipped with a new generation of pulverized coal firing systems. This new system combines ultra-low NO{sub x} vortex burners with a tangential firing concept. The firing system, including the new PF burners, has been developed and tested over the last 5 years including extensive computer modeling and tests on a pilot scale furnace. The new firing system unites the advantages of vortex burners and tangential firing systems. The LCS T-Firing system leads to very low NO{sub x} emissions with high burnout, good ignition in each individual burners, intensive mixing of the flue gas in the furnace, high corrosion protection, good slagging behavior, low part-load operation even with coal only right down to 15% MCR, coupled with high reliability. NO{sub x} emissions between 200 and 300 mg/m{sup 3} STP referred to 6% O{sub 2} (equal to between 0.150 and 0.230 lb./MBTU) with unburned combustibles (UBC) in the fly ash of below 5% have been achieved using a high volatile bituminous German coal.
