Description

Waste heat recovery device and waste heat recovery system including same

The present invention relates to a waste heat recovery device and a waste heat recovery system including the same, and more particularly, to a waste heat recovery device that can be easily applied to a ship or an offshore structure, and a waste heat recovery system including the same.

In general, ships or offshore structures are operated by driving power generated by operating an engine, and power is generated through a generator equipped with a turbine and supplied to be used as internal power.

Here, in a generator that produces electrical energy from thermal energy, a method of converting thermal energy into mechanical energy that moves a piston or a turbine and then using this to produce electrical energy has been used.

However, according to this method, since complex mechanical means must be configured in the generator, the manufacturing cost is high and transportation is difficult. Accordingly, thermoelectric power generation that converts thermal energy into electrical energy has been devised.

A thermoelectric device used in thermoelectric power generation is a generic term for devices using various effects representing the interaction between heat and electricity, and the thermoelectric effect can be largely divided into the Seeback effect and the Peltier effect.

The Seebeck effect represents a thermoelectric phenomenon in which current flows in a closed circuit connecting two metals or semiconductors when a temperature difference occurs between two metals or semiconductors. One terminal absorbs heat and the other terminal generates heat.

Recently, various studies have been attempted to efficiently reuse the high-temperature exhaust gas generated from the engine using such a thermoelectric element without discharging it as it is.
