Assessment of air pollution when incinerating fermented waste with combustion gas components

Abstract

Agriculture and industry facilities produce large quantities of waste, mainly biomass, which could be used to generate electricity. Promoting the use of such waste could reduce environmental pollution and caused adverse ecological effects. The problem of air pollution by incinerating fermented waste in solid fuel boilers with a fixed grate has been analysed. It was found that during incineration of some fermented waste, CO and NOx concentrations exceed limit values. The main cause of high NOx concentrations are large quantities of nitrogen in the burned wastes. The conversion factors of nitrogen to NOx emission has been estimated for the following types of waste: vegetable/fruit - 0.2247; poultry manure - 0.1433, pig manure - 0.0816, and grain residue - 0.0433.
