METHOD FOR USING OF FUEL ADDITIVES BEING NANOSIZED ALLOYS FOR NON-TRANSPARENCY FLAME DECREASING, SCORIFICATION, CONTAMINATION, CORROSION AND RELEASE INTO ATMOSPHERE Russian patent published in 2009 - IPC C10L10/00 C10L9/10 C10L1/10 

FIELD: chemistry.

SUBSTANCE: method for performance improvement of incinerators includes the following stages: burning of the hydrocarbon fuel in incinerator, determination of the given incinerator burning conditions which can be improved by adding of the special additive which conditions are determined on the base of measuring and calculations including hydrodynamical ones; determination of special points location whereat the additives are added to the incinerator; providing on the base of the said stages of the mode of special additive adding to the incinerator in the determine points. The using of the said mode allows to achieve one or more effect selected from the group including: decrease of the flame non-transparency, burning intensification, scorification decrease, reducing of limiting oxygen index, decrease of unburned coal amount, corrosion decrease and improvement of the electrostatic precipitator performance. In the said method the special additive contains the alloy of following general formula (A_a)_n(B_b)_n(C_c)_n(D_d)_n(…)_n whereat every capital letter and (…) means metal with A being burning modificator, B meaning modificator of deposits, C meaning corrosion inhibitor, D meaning comodificator of burning/intensificator of electrostatic precipitator perfomance whereat each subindex means the stoichiometric index of the composition with n being not less than zero, sum of all n is more than zero; alloys includes two different metals; if metal is cerium the stoichiometric index is less than approximately 0.7.

EFFECT: non-transparency decrease of the flame released into atmosphere by large-scale incinerators used in for power production and waste burning industry and community facilities.
