“双碳”目标下燃气电厂天然气混氨技术研究进展

Progress of Research on Natural Gas-ammonia Blending Technology in Gas Power Plants under the"Carbon Peak and Carbon Neutrality"Goals

“双碳”目标下,寻求可靠的减排措施已成为当今社会面临的主要问题。研究发现,将氨与传统化石燃料相互掺混后燃烧可以改善化石燃料碳排放问题,掺氨技术作为一种降低碳方法,正逐渐被应用于锅炉电厂中,而天然气作为更加清洁的化石能源,其与氨气掺混燃烧具有重要研究意义。从点火延迟时间、层流火焰燃烧速度、排放、绝热温度方面总结当前天然气混氨技术发展现状,阐明目前国内燃气电厂天然气混氨技术亟待解决的问题。

Under the"Carbon Peak and Carbon Neutrality"goals,seeking reliable emission reduction measures has become one of the key issues of the world.The study found that blending ammonia with traditional fossil fuels for combustion can improve the carbon emissions of fossil fuels.As a means of reducing carbon emissions,ammonia blending technology is gradually being applied to boilers and power plants.Moreover,the combustion of natural gas,a cleaner fossil energy source,blended with ammonia,has important research significance.This paper summarizes the current development status of natural gas-ammonia blending technology from four aspects:ignition delay time,laminar flame combustion speed,emissions,and adiabatic temperature,and explains the urgent problem to be solved for natural gas-ammonia blending technology in domestic gas power plants.
