Abstract

The invention discloses a combination system of a stirling engine and a combustion gas turbine utilizing liquefied natural gas. The combination system comprises a liquefied natural system, a glycol solution system, an air cooling tank, a combustion gas turbine and connecting components thereof. According to the invention, the stirling engine and the combustion gas turbine are combined, the cold energy of the liquefied natural gas is comprehensively utilized twice: firstly, the stirling engine is directly driven by the cold energy of the liquefied natural gas; and secondly, the air at the air inlet of the combustion gas turbine is cooled by the air cooling tank utilizing low-temperature gaseous natural gas and a glycol solution after heat releasing, and finally, the natural gas after heat release and air are respectively delivered to the combustion gas turbine, the efficient operation of the combustion gas turbine is realized, the cold quantity utilized is greater than the cold quantity of the liquefied natural gas, and the economic property of the combustion gas turbine system is improved.

Description

technical field [0001] The invention relates to a system for efficiently utilizing liquefied natural gas, in particular to a combination system of a Stirling engine and a gas turbine utilizing liquefied natural gas. Background technique [0002] With the development of the global economy, traditional energy sources such as oil are increasingly in short supply. my country's annual imports of liquefied natural gas continue to increase. Liquefied natural gas is a new type of clean fuel, and its volume is only 1 / 625 of gaseous natural gas at the same pressure. Liquefied natural gas The temperature is about -162°C. During the process of gasification into normal temperature natural gas, a large amount of cold energy will be released. At present, most of the LNG receiving stations use seawater to gasify LNG. If these cold energy can be fully utilized, it can greatly improve Improve energy efficiency. [0003] At present, in order to improve the power generation efficiency of gas tur...
