METHOD OF MANUFACTURING LUMP MUNICIPAL-DESTINATION BIOLOGICAL FUEL Russian patent published in 2005 - IPC

FIELD: solid fuels.

SUBSTANCE: invention relates to manufacture of domestic-destination fuel based on peat waste, which may be used in mining industry, local power engineering, municipal economy, metallurgy, railway transport, and environmental protection. Method comprises supplementing peat with additive, mixing the combination, compacting it and drying. In case of milled peat with 40-65% moisture, peat is first separated. Diesel fuel or shale is added to mixture of preliminarily soaked wood waste with coal fines at continuous stirring, resulting mixture is mixed with peat and thus obtained homogenous mixture is charged with sapropel having natural moisture content 85-94%. Finally obtained mixture is stirred and adjusted to 80-85% moisture, after which molded and dried in two steps: first at 150-200°C to 35-50% moisture and then under natural conditions to 25-33% moisture. Percentages of used components are the following, wt %: wood waste 5-10, coal fines 10-20, mazut or shale 5-10, sapropel 10-30, and peat to 100%.

EFFECT: improved environmental safety of product and reduced manufacturing expenses.
