METHOD OF CHARCOAL PRODUCTION Russian patent published in 2002 - IPC

FIELD: control of process of wood pyrolysis in charcoal kilns. SUBSTANCE: the essence of offered invention consists in that in process of pyrolysis, intensity of heat effect on raw material is controlled and heat effect is corrected on the basis that parameter characterized by integral function of heat effect intensity is always found within permissible value for each stage of pyrolysis process. Correction of heat effect is performed by means of variation of special position of container in kiln heat field. EFFECT: higher quality of charcoal, attained uniform heat effect on raw materials, excluded such phenomena as underburning and overburning of charcoal. 2 cl, 4 dwg
