燃料有不同的种类和不同的性质，其中燃料燃烧形成燃气的温度高低与转换效率密切相关；从燃烧形成的燃气温度——如绝热燃烧温度或定压燃烧温度——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，转化的机械能相对较少。There are different types of fuels and different properties, among which the temperature of fuel combustion to form gas is closely related to conversion efficiency; High-grade high-grade fuels correspond to high-grade heat sources and can convert more mechanical energy; while low-grade fuels with low constant-pressure combustion temperature are difficult to form high-temperature combustion products, corresponding to low-grade heat sources, the mechanical energy converted is relatively small.
在常规燃气-蒸汽动力装置中，其采用的汽油、柴油、天然气等燃料均为优质的高品位燃料；受限于燃料性质、工作原理、工作介质、材料性质和部件制造水平等某个或多个因素，低品位的液态或气体燃料，以及品位较高的煤炭，则难以单独在常规燃气-蒸汽动力装置实现高水平的热功转换效率。In conventional gas-steam power plants, gasoline, diesel, natural gas and other fuels used are all high-quality and high-grade fuels; limited by one or more fuel properties, working principles, working medium, material properties, and component manufacturing levels, etc. One factor is that low-grade liquid or gaseous fuels, as well as higher-grade coals, make it difficult to achieve high levels of heat-to-power conversion efficiency in conventional gas-steam power plants alone.
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燃气-蒸汽联合循环动力装置。发明内容：People need simple, active, safe and efficient use of fuel to obtain power.

关于膨胀增速机、燃烧室、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：Here is a brief description of the expansion speed-up machine, combustion chamber, heating furnace, heat source regenerator, low-grade fuel and high-grade fuel:
(1)为揭示汽轮机1和膨胀增速机17在工作流程上的区别，这里作如下解释：(1) In order to reveal the difference in the work flow between the steam turbine 1 and the expansion speed-up machine 17, the following explanations are made here:
①图1/14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3需要的机械能可通过机械传输由汽轮机1或由外部提供。①In Figure 1/14, the steam flows through the steam turbine 1 to achieve thermal power conversion. The steam at the outlet of the steam turbine 1 has a very low pressure and a small flow rate (corresponding to a small kinetic energy), and the mechanical energy required by the booster pump 3 can be mechanically transmitted by the steam turbine. 1 or provided externally.
②相比之下，图13/14中，膨胀增速机17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19降速升压和双能压缩机18部分升压(降速而得)的需要。② In contrast, in Fig. 13/14, the steam at the outlet of the expansion speed-up machine 17 also has a very low pressure, but the flow rate is relatively large (a part of the pressure drop is converted into the kinetic energy of the low-pressure steam) to meet the speed reduction of the diffuser 19. Boost and dual energy compressors 18 are partially boosted (decelerated) as needed.
③对图1/14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13/14中蒸汽流经膨胀增速机17实现热变功的过程采用“降压作功并增速”来表示。③ For the process of steam flowing through the steam turbine 1 to realize thermal power conversion in Fig. 1/14, "depressurization for work" is adopted, and for the process of steam flowing through the expansion speed increaser 17 in Fig. 13/14 to realize thermal power conversion, "depressurization" is adopted. work and increase speed”.
(2)燃烧室9、加热炉10和热源回热器11：(2) Combustion chamber 9, heating furnace 10 and heat source regenerator 11:
①燃烧室9主要用于生成燃气工作介质，必要时内部可设置换热管束以加热其它介质。 ①The combustion chamber 9 is mainly used to generate gas working medium, and if necessary, heat exchange tube bundles can be set inside to heat other media.
②热源回热器11涉及加热炉10内燃气(即热源高温段)的温度品位，单独列出。②The heat source regenerator 11 relates to the temperature grade of the gas (ie, the high temperature section of the heat source) in the heating furnace 10, and is listed separately.
③根据需要，加热炉10内部设置换热管束，对流经其内的介质进行加热——包括用于介质升温的热交换器，还可设置用于受热汽化的蒸发器和对蒸汽进行再热的再热器等。③As required, heat exchange tube bundles are arranged inside the heating furnace 10 to heat the medium flowing through it—including a heat exchanger for heating the medium, an evaporator for heated vaporization, and an evaporator for reheating the steam. reheater etc.
④不具体指明循环介质流经燃烧室或加热炉受热时所涉及到的具体换热管束，而统一采用燃烧室或加热炉来表述。④ The specific heat exchange tube bundles involved when the circulating medium flows through the combustion chamber or the heating furnace are not specified, but the combustion chamber or the heating furnace is uniformly expressed.
(3)低品位燃料和高品位燃料：(3) Low-grade fuel and high-grade fuel:
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；相对于汽柴油来说，荒煤气则是低品位燃料。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。①Low-grade fuel: refers to the fuel with a relatively low maximum temperature (such as adiabatic combustion temperature or constant pressure combustion temperature) that can be formed by combustion products; compared with gasoline and diesel, waste gas is a low-grade fuel. From the concept of heat source, low-grade fuel refers to fuel whose combustion products are difficult to form a high-temperature heat source with higher temperature.
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；如相对于煤矸石、煤泥等燃料而言，优质煤、天然气、甲烷、氢气等都是高品位燃料。从热源的概念来看，低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。②High-grade fuel: refers to the fuel with the highest temperature (such as adiabatic combustion temperature or constant pressure combustion temperature) that can be formed by combustion products; for example, compared with coal gangue, coal slime and other fuels, high-quality coal, natural gas , methane, hydrogen, etc. are all high-grade fuels. From the concept of heat sources, low-grade fuels refer to fuels whose combustion products can form high-temperature heat sources at higher temperatures.
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。③ For solid fuels, the gaseous substances of the combustion products are the core of the heat source and are an important part of the thermal system; while the solid substances in the combustion products, such as waste residues, can be utilized when they contain thermal energy (the utilization process and equipment are included in the The preheated air in the heating furnace or outside the heating furnace body) is discharged after it is not listed separately, and its function is not described separately.
具体实施方式：Detailed ways:
