FIELD: chemistry.
SUBSTANCE: present invention pertains to making ceramic products from natural mineral raw materials and can be used for burning crude products in a hydrogen reducing medium. The layer of products to be burnt is put on top of a layer of carbon-bearing reducing agent. The reducing agent is oxidised by hot combustion products of hydrocarbon fuel (carbon dioxide and water vapour), forming carbon and hydrogen oxide. Burning takes place in a hydrogen atmosphere. Carbon oxide is removed from the bottom of the reaction zone. The combustion products of hydrocarbon fuel are passed through the layer of carbon-bearing reducing agent from top to bottom, at a rate which allows for keeping the formed hydrogen in the layer of the burned products.
EFFECT: increased output of the method due to increased volume of burned products, through retention and repeated use of hydrogen in an open reactor.
