|Alfa Laval - a marine provider of boiler technology, combustion technology and solutions for environmental compliance - has published a new white paper detailing the impact of MARPOL Annex VI fuel strategies on boilers and burners.
The paper, entitled 'MARPOL Annex VI fuel strategies and their influence on combustion in boilers', sheds light on a frequently overlooked aspect of meeting today's sulphur oxide (SOx) emission regulations. To comply with MARPOL Annex VI, ship owners and operators can install a scrubber and continue using heavy fuel oil (HFO), or they can decide to use compliant fuels such as liquefied natural gas (LNG), marine gas oil (MGO) or low-sulphur/ultra-low-sulphur HFO. But while the boiler is generally not a part of this decision, its operation will ultimately be affected.
"Depending on the choice made, there can be many different factors to consider when it comes to boilers and burners," explained Jeroen Van Riel, Global Service Manager, Boiler Service at Alfa Laval. "There may be boiler modifications needed to perform optimally with a scrubber, or there may be issues with fuel line safety and the properties of alternative fuels. New flame characteristics, for example, may produce different results with an existing boiler configuration."
In the new white paper, each MARPOL Annex VI fuel strategy is examined individually, together with its potential effects on boilers and their combustion. The paper does not argue for or against any of the strategies, but rather aims to provide a clear and neutral overview from the perspective of steam production.
Alfa Laval believes it is well placed to provide knowledge about this topic. The company has been developing and supplying marine boiler technology for nearly a century, and today's Alfa Laval Aalborg boilers and burners include solutions for working with multiple fuel types.
Also, as provider of the PureSOx scrubber solution and developer of fuel conditioning and supply systems for both traditional and alternative fuels, Alfa Laval notes that it has gained significant insight into strategies for MARPOL Annex VI compliance.
"As a full-scope supplier, Alfa Laval's aim is to provide complete solutions and support, regardless of the customer's fuel choices," remarked Van Riel.
"Our new white paper can be a valuable tool for customers in evaluating the issues and getting the best performance from their boilers, no matter which fuel strategy they decide on," he added.
