1.4.1. Brief description of technologies of vanadium-containing emission reduction at liquid fuel combustion

Anichkov S.N., Glebov V.P.; JSC “VTI”

At liquid fuel combustion in boiler plants, in addition to gas combustion products, solid substances are generated. The last consist of mineral fuel components and organic substances - products of incomplete combustion (such as soot, coke, benzapyrene). Mineral components, mainly, include metal compounds: vanadium, nickel, iron, aluminum, cobalt, etc. An average composition of mineral part of domestic oil in oxide equivalent contains: sodium oxide — 20…40 %, silicon oxide — 5…20 %, vanadium pentoxide — 20…30 %, magnesium oxide — 3…10 %, iron trioxide — 3…20 %, sulfur trioxide —20…40 %.

Benzapyrene (BP) represents a solid crystallized substance in a form of daffodil needles. By a level of affect on a human body BP is referred to the first class of hazard (extremely hazardous substances). Sometimes BP is called as blastomogenic substance, that is, the substance able to cause all possible tumors and neoplasms in the living organism. These formations can be both cancerous (cancer and sarcoma) and others (adenoma, papilloma, etc.).
