摘　　要：工程建设浙江石化二期3×SGT5-2000E燃气-蒸汽联合发电机组,现场提供的主燃料为天然气,在满足蒸汽供热能力的前提下掺烧部分炼油化工合成气。按一定比例混合,使混合气在所要求的压力和流量下输送到下游燃气轮机前置模块中,满足燃气轮机启动及运行要求。由于合成气中含41%的H2和53%的CO,需要充分考虑H2和CO的特殊性质。该项目混气站的设计制造,是国内首套掺烧含氢41%合成气的燃气轮机项目,为中国在未来烧氢方向的燃气轮机业务奠定了坚实的基础。Zhejiang Petrochemical phaseⅡ3×SGT5-2000E gas-steam combined cycle unit is to be built in the project.The main fuel provided at the site is natural gas,which is blended with part of the refining and chemical synthesis gas on the premise of meeting the steam heating capacity.According to a certain proportion of mixing,the mixture will be delivered to the downstream gas turbine front module under the required pressure and flow,to meet the requirements of gas turbine start-up and operation.Because the syngas contains 41%hydrogen and 53%carbon monoxide,the special properties of hydrogen and carbon monoxide need to be fully considered.The design and manufacture of the gas mixing station of the project is the first gas turbine project in China to burn syngas containing 41%hydrogen,which lays a solid foundation for the gas turbine business in the direction of hydrogen burning in the future in China.
