В работе представлены результаты исследования возможности использования биогаза, обогащенного водородом, на паротурбинной мини-ТЭС мощностью 1 МВт, в которой был организован процесс аккумулирования тепловой энергии. Двухстадийная биологическая конверсия органических отходов была рассмотрена в технологической схеме как основа получения биоводорода и биогаза. Пять составов газообразного топлива было проанализировано в этой работе. Содержание биоводорода варьировали с шагом от 15% до 45%. При генерировании пара применялся котел производительностью 25 т/ч, его расчет являлся ключевым в блоке получения энергии. Для быстрой переработки отходов с минимальным временем гидравлического удержания наиболее эффективно использование газа с содержанием водорода до 15%. Ежедневная переработка отходов составит при этом от 349,87 до 362,21 тонн, а избыток технического водорода чистоты 99,99% можно будет реализовать в баллонах. Количество органических удобрений, получаемое на мини-ТЭС, будет составлять не менее 241 т/сут. КПД парового котла будет равен 95%. Полученный пар направляется в паровую турбину мощностью 1 МВт для производства электроэнергии. Хотя наименьшее количество дымовых газов образуется при сжигании в паровом котле топлива с содержанием водорода 45%, это технологически невозможно реализовать в рассматриваемой схеме, т. к. имеется дефицит H2. Следует отметить, что расход топлива в паровом котле растет по мере увеличения доли водорода. На основании всестороннего анализа можно утверждать, что для проектирования паротурбинной мини-ТЭС на водороде недостаточно стандартных методик и необходимо проведение дополнительных исследований.

The paper presents the results of a study of the possibility of using biogas enriched with hydrogen at a steam-turbine mini-thermal power plant with a capacity of 1 MW, in which the process of heat energy accumulation was organized. Two-stage biological conversion of organic waste was considered in the technological scheme as the basis for obtaining biohydrogen and biogas. Five compositions of gaseous fuels were analyzed in this paper. The biohydrogen content was varied in increments of 15% to 45%. When generating steam, a boiler with a capacity of 25 tons /hour was used; its calculation was key in the power generation unit. For fast recycling of waste with minimal hydraulic retention time, the most effective way is to use gas with a hydrogen content of up to 15%. At the same time, the daily processing of waste will be from 349,87 to 362,21 tons, and the excess of technical hydrogen of 99,99% purity can be realized in cylinders. The amount of organic fertilizers produced at the mini-TPP will be at least 241 tons /day. The efficiency of the steam boiler will be 95%. Resulting steam is sent to a 1 MW steam turbine to generate electricity. Although the smallest amount of flue gases is generated by burning fuel with a hydrogen content of 45% in a steam boiler, this is technologically impossible to implement in the scheme under consideration, since there is a shortage H2. It should be noted that the fuel consumption in a steam boiler increases as the proportion of hydrogen increases. Based on a comprehensive analysis, it can be argued that there are not enough standard methods for designing a steam-turbine mini-thermal power plant on hydrogen, and additional research is necessary.
