Experimental study on power generation plant of a 1 kW small‐scale Organic Rankine Cycle system using R290

Abstract

Currently, the global warming effect has been approved worldwide, and the greenhouse gas emissions from conventional power generation plant have caused more and more concerns. 1 The natural gas, as a clean energy, which has a characteristic of high calorific value and less greenhouse gas emission when it is burned as a fossil fuel. 2,3 The best way to storage and long-distance transportation across ocean of the natural gas is usually liquefied into liquefied natural gas (LNG) at a temperature of approximately −162 and atmospheric pressure, 4,5 which can increase the energy density and easy for transport. However, LNG must be gasified into natural gas at ambient temperature in LNG terminals prior to use. 6 The regasification process of LNG will release a lot of 830 KJ/Kg cold energy by absorbing heat from the seawater, 7 air, and industry waste heat in the LNG terminals, which will not
