FUEL BRIQUETTE, AND METHOD FOR ITS OBTAINING Russian patent published in 2012 - IPC C10L5/02 C10L5/10 C10L5/14 

FIELD: oil and gas industry.

SUBSTANCE: invention refers to fuel briquette that contains coke and anthracite fines, molasses as binding agent and additional binding agent - industrial vegetable oil. At that, briquettes have cylindrical shape with the following dimensions: diameter x height - 100x100 or 110x110 or 120x120 mm. The invention also refers to the method for obtaining fuel briquettes, which involves dosing, mixing of coke and anthracite fines and binding agent - molasses, briquetting of mixture under pressure of 35-50 MPa and drying of briquettes, and which differs by the fact that industrial vegetable oil is added to molasses prior to dosing at the following ratio of molasses : oil, wt %: 9-12 : 0.5-2; briquettes are arranged on trolleys and drying is performed at continuous discrete trolley movement (every 10 minutes) through the distance equal to the length of one trolley; at that, temperature vs. time drying mode is characterised with three stages: first stage - 100-300°C during 40 minutes, the second stage - 380-200°C during 100 minutes, the third stage - 200-100°C; besides, drying of briquettes at the first stage is performed with opposite flow in relation to trolley movement, and with cocurrent flow of drying agent at the second and the third stages.

EFFECT: improvement of the method.
