Experience with a new low-NO{sub x} firing system
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 summer 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 during 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 burner, 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 STP referred to 6% O{sub 2} with unburned combustibles (UBC) in the fly ash of below 5% have been achieved using a high volatile bituminous German coal.
