Description

双燃料燃气-蒸汽联合循环动力装置Dual fuel gas-steam combined cycle power plant 技术领域：Technical field:
本发明属于热力学与热动技术领域。The invention belongs to the technical field of thermodynamics and thermodynamics.
背景技术：Background technique:
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，进而通过燃气-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。Cold demand, heat demand and power demand are common in human life and production; among them, the chemical energy of high-quality fuel is converted into thermal energy through combustion, and then the thermal energy is efficiently converted into mechanical energy through a gas-steam power plant. An important means for humans to provide power or electricity.
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。There are different types of fuels and different properties. The temperature of the gas formed by the combustion of the fuel directly determines the thermal power conversion efficiency; from the temperature of the gas formed by combustion (such as the combustion temperature at constant pressure) High-grade fuels correspond to high-grade heat sources, which can convert more mechanical energy; while low-grade fuels with low constant-pressure combustion temperatures are difficult to form high-temperature combustion products, corresponding to low-grade heat sources—relative to the former, less mechanical energy can be converted.
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；由于受限于工作原理或材料性质或设备制造水平等原因，其优质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。In conventional gas-steam power plants, the gasoline, diesel, natural gas and other fuels used are high-quality and high-grade fuels; due to the limitation of working principle or material properties or equipment manufacturing level, the high-quality and high-grade fuels form high temperature During the combustion process of the heat source, the difference between the temperature of the combustion-supporting medium (such as air) and the combustion temperature of the fuel at constant pressure is large, and there is a large irreversible loss of the temperature difference in the combustion process, which leads to the loss of mass in the utilization of the fuel - however, this is low. The opportunity for grade fuels to participate in the construction of heat sources.
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。People need simple, active, safe and efficient use of fuel to obtain power. The present invention provides the rational use of low-grade fuel and high-grade fuel to achieve learning from each other's strengths and complement each other's advantages, and greatly improve the thermal power conversion efficiency of low-grade fuel. A dual-fuel gas-steam combined cycle power plant that reduces greenhouse gas emissions and effectively reduces fuel costs.

关于膨胀增速机、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：Here is a brief description of the expansion speed increaser, air 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13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 increaser 13, the following explanations are made here:
①图1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。①In Figure 1, steam flows through steam turbine 1 to achieve thermal power conversion. The steam at the outlet of 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 2 can be transmitted by the steam turbine 1 or by the mechanical transmission. Provided externally.
②相比之下，图11/14中，膨胀增速机13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14降速升压的需要。② In contrast, in Fig. 11/14, the steam at the outlet of the expansion speed-up machine 13 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 pipe 14. Boost needs.
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11/14中蒸汽流经膨胀增速机13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 Figure 1/14, "depressurization to work" is used, and for the process of steam flowing through the expansion speed increaser 13 to realize thermal power conversion in Figure 11/14, "depressurization" is adopted. work and increase speed”.
(2)关于空气加热炉和热源回热器的说明：(2) Instructions on air heating furnace and heat source regenerator:
①本发明申请中，空气加热炉7承担对进入二段燃烧室8的空气的加热任务，同时为动力装置提供部分高温驱动热负荷；一些情况下，空气加热炉7还承担对底部朗肯循环子***循环蒸汽的加热任务。① In the application of the present invention, the air heating furnace 7 undertakes the task of heating the air entering the second-stage combustion chamber 8, and at the same time provides part of the high-temperature driving heat load for the power plant; in some cases, the air heating furnace 7 also undertakes the bottom Rankine cycle. Subsystem circulates steam for heating tasks.
②根据需要，空气加热炉内部设置相关热交换器(换热管束)；比如，图8/14中对来自高温热交换器3的蒸汽进行加热的过热器，图9/14中对来自汽轮机1的蒸汽进行加热的再热器。②As required, relevant heat exchangers (heat exchange tube bundles) are installed inside the air heating furnace; for example, the superheater for heating the steam from the high temperature heat exchanger 3 in Fig. The steam is heated by the reheater.
③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 The specific heat exchange tube bundle (superheater or reheater) is not specified, but the air heating furnace is uniformly expressed.
④热源回热器涉及空气加热炉内燃气的温度品位，单独列出。④The heat source regenerator refers to the temperature grade of the gas in the air heating furnace, which is listed separately.
(3)关于燃料的说明：(3) Instructions on 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，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。①Low-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, such as coal gangue, coal slime, combustible garbage, etc. 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，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。②High-grade fuel: refers to the fuel with relatively high highest temperature (such as adiabatic combustion temperature or constant pressure combustion temperature) that can be formed by combustion products, such as high-quality coal, natural gas, methane, hydrogen, etc. From the concept of heat source, high-grade fuel refers to fuel whose combustion products can form a high-temperature heat source with higher temperature.
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***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。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 residue, the heat energy contained in them is utilized (the utilization process and equipment are included in the In the boiler, or after preheating air outside the boiler body), it is not required to be listed separately, and its function is not described separately.
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。④Limited by the current technical conditions or material properties, especially for fuels that need to provide the circulating working fluid with high-temperature heat load through indirect means, their grades should be based on the highest temperature that the combustion products can form minus the indirect fuel. It is divided by the temperature after the heat transfer temperature difference; or, it can be divided by the temperature that the circulating working fluid can reach under the current technical conditions - the higher temperature that the circulating working fluid (working medium) can reach is the high grade. Fuel, the lower temperature that the circulating working fluid (working medium) can reach is the low-grade fuel.
