NOx emission below 70 mg/Nm3 when firing fuel gas containing high H2 % at NEREFCO (Netherlands) 

In 2007, NEREFCO, formerly British Petroleum (BP), Europoort refinery (NL), decided to increase their steam production with a new water tube steam boiler (130 t/h, 29.5 barg superheated steam).

They decided to install the best available techniques for Low Nox burners firing fuel gas containing a high H2 % (up to 58 %vol.) including the following targets:

NOx emission when firing fuel gas: < 70 mg/Nm3, @ 3% O2 dry basis.

CO emission when firing fuel gas: < 50 mg/Nm3, @ 3% O2 dry basis.

Maximum boiler availability.
