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，将不同品质的化石燃料、生物质燃料等通过燃烧形成高温热源，是进行冷、热、动力生产与利用的首要环节；减少高温热源形成过程的温差不可逆损失，是实现能源高效利用的关键和首要环节；将燃料的化学能通过燃烧转换为热能，进而通过不同的热变功装置再将热能转换为机械能，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 combustion of fossil fuels and biomass fuels of different qualities to form high temperature heat sources is the primary link for cold, heat and power production and utilization ; Reducing the irreversible loss of temperature difference in the formation process of high temperature heat source is the key and primary link to achieve efficient energy utilization; converting the chemical energy of fuel into thermal energy through combustion, and then converting thermal energy into mechanical energy through different thermal power conversion devices 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 the conversion efficiency; from the temperature of the gas formed by combustion - such as adiabatic combustion temperature or constant pressure 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.
由于受限于工作原理，或受限于工作介质的性质，或受限于材料性质，或受限于压缩设备及其它部件的制造水平等原因，采用高品位优质燃料的气体动力装置中，燃烧室内高温热源的形成过程中存在较大的温差损失，这带来较大的燃料利用上的质量损失——不过，这为低品位燃料参与高温热源构建和提供驱动热负荷带来了机遇。Due to the limitation of the working principle, or the properties of the working medium, or the properties of the materials, or the manufacturing level of the compression equipment and other components, etc., in the gas power plant using high-grade and high-quality fuel, combustion There is a large loss of temperature difference in the formation of indoor high-temperature heat sources, which brings about a large mass loss in fuel utilization—however, this brings opportunities for low-grade fuels to participate in the construction of high-temperature heat sources and provide driving heat loads.
人们需要简单、主动、安全、高效地利用燃料来形成高温热源，本发明给出了将低品位燃料与高品位燃料进行合理搭配使用，实现取长补短和优势互补，能够同时提升两种燃料利用价值，减少温室气体排放，以及有效降低燃料成本的双燃料高温热源与双燃料燃气轮机装置。People need simple, active, safe and efficient use of fuel to form a high-temperature heat source.
