Description

双燃料联合循环动力装置 技术领域：
本发明属于联合循环热动技术领域。
背景技术：
动力需求为人类生活与生产所常见，利用燃料燃烧形成的热能转换为机械能是获得和提供动力的重要方式，实现高效热变功需要合理的热力循环和驱动热源。
燃料是构建高温热源的重要选项，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。受工作原理、工作介质性质、材料性质、设备及其它部件制造水平等某一或多个因素所限制，在采用高品位燃料的热动装置中，燃烧过程存在较大温差不可逆损失——这为低品位燃料参与构建热源提供了机遇。
以朗肯循环为理论基础的蒸汽动力装置，其放热过程温差损失小，但循环工质与热源之间温差损失大，热效率低；以布雷顿循环为理论基础的热动装置，其吸热环节中的温差损失相对可控，但其功率、热效率和升压比之间常常有难以协调的矛盾。
人们需要简单、主动、安全、经济、高效地利用燃料来获得动力，本发明给出了低品位燃料与高品位燃料搭配使用，实现取长补短和优势互补，大幅度提高低品位燃料利用价值，热效率高、安全性强、功率匹配灵活的非直燃型双燃料联合循环动力装置。

关于低品位燃料和高品位燃料，这里给出简要说明：
(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。从热源的概念来看，低品位燃料指的是燃烧产物的温度相对较高的燃料。
(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。从热源的概念来看，高品位燃料指的是燃烧产物的温度相对较高的燃料。
(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，在其含有热能得到利用(利用流程及设备包含在加热炉内或在加热炉本体之外预热空气)之后被排出，不单独列出，其作用不单独表述。
(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。
