Air pollution reduction by using of low nox burners for furnaces and boilers

Abstract

Air pollution reduction can be mainly made by modernization of furnaces and boilers. At present, modernization means using of low NOx burners for decreasing pollutants emission from exhausted gases. In the same time, modernization means decreasing of energy consumptions, i.e. reduction of CO2 quantities in the atmosphere. This paper presents recently designed, manufactured and tested low NOx burners types, of own original conception, for furnaces and boilers. The research results emphasized the influence of some parameters on NOx emission from exhausted gases. Some important parameters were pointed out, such as: the burner and fuel type, the air ratio coefficient and the chamber temperature. Also, there are presented experimental results obtained on industrial furnaces and boilers equipped with low NOx burners. The experimental results revealed the following situation: pollutants emission below the limit values of EU standards; reduction of energy consumptions against the classical burners with 10-30%; improving of heating uniformity.
