Description

双燃料联合循环动力装置 技术领域：
本发明属于热力学与热动技术领域。
背景技术：
冷需求、热需求和动力需求，为人类生活与生产当中所常见；其中，将优质燃料的化学能通过燃烧转换为热能，进而通过气体-蒸汽动力装置再将热能高效地转换为机械能，是向人类提供动力或电力的重要手段。
燃料有不同的种类和不同的性质，其中燃料燃烧所形成燃气的温度高低直接决定着热变功效率；从燃烧形成的燃气温度(如定压燃烧温度)来看，定压燃烧温度高的高品位燃料，对应着高品位热源，可转化更多的机械能；而定压燃烧温度低的低品位燃料，难以形成高温燃烧产物，对应着低品位热源——相对前者，可转化较少的机械能。
在采用高品位燃料为气体-蒸汽动力装置提供高温热负荷时，由于受限于工作原理或材料性质或设备制造水平等原因，使得高品位燃料形成高温热源的燃烧过程中，助燃介质(如空气)温度与燃料定压燃烧温度之间差别较大，燃烧过程中存在较大温差不可逆损失，这导致燃料利用上的质量损失——不过，这为低品位燃料参与构建热源提供了机遇。
人们需要简单、主动、安全、高效地利用燃料来获得动力，本发明给出了将低品位燃料与高品位燃料合理搭配使用，实现取长补短和优势互补，大幅度提高低品位燃料热变功效率，减少温室气体排放，并能够有效降低燃料成本的双燃料联合循环动力装置。

关于膨胀增速汽轮机、空气加热炉、热源回热器、低品位燃料和高品位燃料，这里给出如下简要说明：
(1)为揭示汽轮机1和膨胀增速汽轮机14在工作机理上的区别，这里作如下解释：
①图1/19中，蒸汽流经汽轮机1实现热变功，汽轮机1出口蒸汽具有很低压力和较小流速(对应较小的动能)，升压泵2需要的机械能可通过机械传输由汽轮机1或由外部提供。
②相比之下，图16/19中，膨胀增速汽轮机14出口蒸汽同样具有很低的压力，但流速相对较大(一部分压降转换为低压蒸汽的动能)以满足扩压管15降速升压的需要。
③对图1/19中蒸汽流经汽轮机1实现热变功的过程采用“降压作功”，对图16/19中蒸汽流经膨胀增速汽轮机14实现热变功的过程采用“降压作功并增速”来表示。
(2)关于空气加热炉和热源回热器的说明：
①根据需要，空气加热炉内部设置相关热交换器(换热管束)；如，图13/19中对来自高温热交换器3的蒸汽进行加热的过热器，图14/19中对来自汽轮机1的蒸汽进行加热的再热器。
②不具体指明具体换热管束(过热器或再热器)，而统一采用空气加热炉来表述。
③本发明申请中，空气加热炉7提供高温热源初始段热负荷，并承担对进入锅炉8的空气进行加热升温任务；一些情况下，还承担对底部朗肯循环子系统循环蒸汽的加热任务。
④热源回热器涉及空气加热炉和锅炉内燃气的温度品位，单独列出。
(3)关于燃料的说明：
①低品位燃料：指的是燃烧产物所能够形成的最高温度(比如绝热燃烧温度或定压燃烧温度)相对较低的燃料，比如煤矸石、煤泥、可燃垃圾等。从热源的概念来看，低品位燃料指的是燃烧产物难以形成较高温度的高温热源的燃料。
②高品位燃料：指的是燃烧产物所能够形成的最高温度(比如绝热燃烧温度或定压燃烧温度)相对较高的燃料，比如优质煤、天然气、甲烷、氢气等。从热源的概念来看，高品位燃料指的是燃烧产物能够形成较高温度的高温热源的燃料。
③对固体燃料来说，燃烧产物的气态物质是构成热源的核心，是热力系统的重要组成部分；而燃烧产物中的固态物质，如废渣，其含有的热能被利用(利用流程及设备包含在锅炉内，或在锅炉本体之外预热空气)之后被排出，无需单独列出，其作用也不单独表述。
④受限于现行技术条件或材料性能等原因，尤其对于需要通过间接手段向循环工质提供驱动高温热负荷的燃料来说，它们的品位高低应以燃烧产物所能够形成的最高温度减去间接传热温差之后的温度高低来划分；或者，以现行技术条件下能够使循环工质所能达到的温度高低来划分——使循环工质(工作介质)能够达到的温度更高者为高品位燃料，使循环工质(工作介质)能够达到的温度较低者为低品位燃料。
