METHOD AND APPARATUS FOR INDICATING A RISK OF CORROSION OR SCUFFING OF COMPONENTS OF A COMBUSTION CHAMBER OF A TURBOCHARGED ENGINE ARRANGEMENT, IN PARTICULAR FOR VESSELS, AND TURBOCHARGED ENGINE ARRANGEMENT FOR VESSELS

摘要

In order to provide a method for indicating a risk of corrosion or scuffing of components of a combustion chamber of a turbo charged engine arrangement, in particular for vessels, the turbo charged engine arrangement includes a turbocharger and a charge gas cooler. A first gas stream of an ambient gas enters into the turbocharger, a second gas stream of charge gas flows from the turbocharger to the charge gas cooler, and the second gas stream of charge gas enters into the charge gas cooler. A third gas stream of charge gas flows from the charge gas cooler to the combustion chamber, and the third gas stream of the charge gas enters into the combustion chamber.

1. Method for indicating a risk of corrosion or scuffing of components of a combustion chamber of a turbo charged engine arrangement, in particular for vessels, wherein the turbo charged engine arrangement comprises a turbocharger and a charge gas cooler, wherein a first gas stream of an ambient gas enters into the turbocharger, wherein a second gas stream of charge gas flows from the turbocharger to the charge gas cooler, wherein the second gas stream of charge gas enters into the charge gas cooler, wherein a third gas stream of charge gas flows from the charge gas cooler to the combustion chamber, and wherein the third gas stream of charge gas enters into the combustion chamber, comprising the steps of:
a) measuring parameters, wherein the measured parameters comprise at least one gas temperature, at least one gas pressure, a first water content of the charge gas of the third gas stream and a liner temperature of a liner of the combustion chamber, and b) determining, in particular calculating, a second water content of a gas in the combustion chamber based on the measured parameters, and c1) indicating the determined second water content as an indicator of the risk of corrosion or scuffing of components of the combustion chamber, and/or c2) comparing the determined second water content with at least one pre-determined value and indicating the risk of corrosion of components or scuffing of the combustion chamber when the determined second water content is higher and/or equal and/or lower than the at least one pre-determined value, and/or c3) adjusting an operating parameter of the turbo charged engine.
