Abstract. The method relates to the field of industrial heat and power engineering. It can be used in coal preparation plants for processing coal waste. This new way is realized to produce a loose ash residue directed to the production of silicate products and fuel gas in rotary kilns. The proposed method is associated with industrial processing of brown coal beneficiation waste. Waste is obtained by flotation separation of rock particles up to 13 mm in size from coal particles. They have in their composition both solid and volatile fuel inclusions (components). Due to the high humidity and significant rock content, low heat of combustion, these wastes are not used on energy boilers, they are stored in dumps polluting the environment.
Пусть $u\not\equiv-\infty$ - субгармоническая функция на
комплексной плоскости. Устанавливаются необходимые и/или
достаточные условия существования ненулевой целой функции $f$,
для которой модуль произведения каждой ее $k$-й произ водной,
$k=0,1,…$, на любой многочлен $p$ не больше функции $Ce^u$
на всей комплексной плоскости, где $C$ - постоянная, зависящая
от $k$ и $p$. Полученные результаты существенно усиливают
и развивают ряд результатов Ларса Хeрмандера 1997 г.
