摘要： 天然气在门站的调压过程中，由于焦耳-汤姆逊效应，出口温度下降，需在天然气门站中采取加热措施。提出了
一种微型分布式能源系统在天然气门站加热的技术路线，系统由微型热电一体机及空气源热泵组合而成，为门站提供工艺
热水。通过与常规的电加热和燃气锅炉方式进行比较，微型分布式能源系统的经济性和节能减排优势明显，技术经济可行。

Abstract: The outlet temperature of natural gas will decrease during pressure regulating in natural gas gate station due to Joule-
Thomson effect, and heating measures should be adopted in natural gas gate station. This paper proposed a technical route of
micro-distributed energy system heating in natural gas gate station. The system is composed of mico-cogenerator and air source
heat pump to provide process hot water for the gate station. Compared with conventional electric heating and gas-fired boilers, the
micro-distributed energy system has obvious advantages in economy, energy conservation and emission reduction, and is
technically and economically feasible.

Key words: natural gas gate station; micro-distributed energy system; economic analysis; energy conservation and emission
