This information is
provided for the data archive of users of steam boilers with burners
consuming fuel oil, and is extracted from our Database of average data from
the analysis of combustion gases recorded during recent years in several
Data are included for periods prior to 01/01/2003,
for boilers that used Fuel Oil No. 2 (Spanish standards), with 2.7%
sulphur, and similar data, from 01/01/2003 onwards, using fuel oil
with a maximum sulphur content of 1%, obligatory in the European Union
since 1 January 2005.
The data on emissions always refer to a content of O2
of 3% in exhaust gases, in accordance with legal regulations to limit
pollutant emissions in boilers, in order that the data should appear
homogeneous and comparative. The Bacharach Index is determined for gases as
they leave the manifolds, that is, with their actual O2 content.
