Повышение эффективности использования топлива применительно к энергоемким производствам, таким как электро- и теплоэнергетика, металлургия и нефтехимия, является актуальной задачей. Одно из направлений повышения энергоэффективности на предприятиях данных отраслей – полезное использование бросовой теплоты отходящих газов. Перспективным технологическим направлением в данной области является энергохимическая аккумуляция – термохимический процесс, заключающийся в производстве из продуктов сгорания синтетического водородосодержащего топлива, при этом теплота продуктов сгорания используется для обеспечения протекания эндотермических реакций, например, реакций паровой конверсии. Однако, для разработки технических и технологических решений в области энергохимической аккумуляции необходимы надежные математические модели, в том числе – кинетические механизмы. Настоящее исследование посвящено валидации кинетического механизма GRI-MECH 3.0 применительно к процессам энергохимической аккумуляции теплоты продуктов сгорания метана. В качестве объекта исследования рассматривалась модель технологической печи, в которой осуществлялось кислородное горение метана с добавлением к продуктам его сгорания вторичного метана. Посредством численного моделирования и экспериментальных исследований было установлено протекание при данных условиях реакций паровой конверсии с образованием водорода и монооксида углерода, при этом кинетический механизм GRI-MECH 3.0 демонстрирует приемлемую точность при коэффициенте избытка окислителя, отнесенном к расходу первичного метана в диапазоне 0,9-1,1. При значительном недостатке кислорода результаты экспериментальных и численных исследований значительно расходятся, что обусловлено некоторой идеализацией процессов неполного сгорания метана в используемых моделях.

Improving fuel efficiency in energy-intensive industries such as electric and thermal power generation, metallurgy, and petrochemistry is a pressing issue. One approach to improving energy efficiency in these industries is the beneficial use of waste heat from exhaust gases. A promising technological approach in this area is energy-chemical accumulation, which is a thermochemical process that involves producing synthetic hydrogen-containing fuel from combustion products. The heat from the combustion products is used to fuel endothermic reactions, such as steam reforming. However, developing technical and technological solutions for energy-chemical accumulation requires reliable mathematical models, including kinetic mechanisms. This study validates the GRI-MECH 3.0 kinetic mechanism for energy-chemical accumulation of methane combustion products. The study focused on a model of a process furnace that involved oxygen-based methane combustion with the addition of secondary methane to the combustion products. Numerical modeling and experimental studies established that steam reforming reactions with hydrogen and carbon monoxide formation occur under these conditions. The GRI-MECH 3.0 kinetic mechanism demonstrates acceptable accuracy with an oxidizer excess ratio (relative to the primary methane consumption) in the range of 0.9-1.1. At significant oxygen deficiencies, the experimental and numerical results diverge significantly, due to a certain idealization of incomplete methane combustion processes in the models used.
