一种IGCC电厂储热储氧储能供热调峰系统
技术领域
本发明涉及火电厂发电技术领域，尤其涉及一种IGCC电厂储热储氧储能供热调峰系统。
背景技术
随着经济社会的不断发展，能源的需求与日俱增，化石能源存在污染日益严重，发展清洁、可再生的能源势在必行，国家鼓励清洁能源发电和供热。IGCC发电是把煤气化、煤净化技术和高效的燃气蒸汽联合循环发电技术相结合，实现了煤炭资源的高效、洁净利用，具有高效、洁净、节水、燃料适应性广、易于实现多联产等优点，并且与未来燃烧前二氧化碳捕集、氢能等可持续发展相结合，是洁净煤发电技术的重要发展方向之一。

在气化炉合成气通道中设置合成气换热器3，加热储热介质，实现热量储存。换热器气体流动方式可以是顺流、逆流、交叉流等方式。
