Arrangement handling purged alcohol-based fuel and a method thereof

An arrangement for handling purged alcohol-based fuel originating from an alcohol fuel system configured to fuel an alcohol fueled engine, the arrangement comprising:

• a boiler system comprising
• a burner, and
• a fuel inlet configured to selectively supply a fuel and thereby selectively sustain a primary flame in the burner for production of heat and/or steam in the boiler system, and
• a purge connection configured to receive a purge mixture purged from the alcohol fuel system using an inert gas, the purge mixture comprising a mixture of the inert gas and purged alcohol-based fuel, and
• a vapor-liquid separator,
• wherein the arrangement is configured to selectively
• direct at least a vapour phase of the purge mixture from the purge connection to a vapour phase purge mixture inlet of the boiler system in case the boiler system is in a hot condition and is ready to receive and combust purge mixture, the vapour phase purge mixture inlet being configured to intermittently receive vapour phase of the purge mixture from the alcohol fuel system and supply the vapour phase of the purge mixture to the burner, wherein the burner is configured to combust the vapour phase of the purge mixture, or to selectively
• direct the purge mixture from the purge connection to the vapor-liquid separator separating the purge mixture into a vapour phase and a liquid phase, whereafter the liquid phase is stored in the vapor-liquid separator and/or in a separate tank until the boiler system is in a hot condition and is ready to receive and combust the liquid phase of the purge mixture.
