Abstract: An exhaust gas heat energy recovery and pollution control system for a marine vessel is disclosed. The system includes (a) an exhaust gas boiler that receives exhaust gases from a gas or fuel oil-burning internal combustion engine, (b) a variable capacity wet scrubbing system that sprays a mixture into the exhaust gases, (c) two or more condensing heat exchangers that receive exhaust gases, (d) a variable flow and variable pressure exhaust gas mover that facilitates movement of the exhaust gases, (e) a liquid collection and treatment system that collects liquid condensate, (f) one or more heat sinks to receive thermal energy from exhaust gases, (g) an interconnecting fluid conduit that allows for movement of exhaust gases, and (h) a control system communicatively coupled with a plurality of sensors, actuators, and external interfaces.
