FEATURES OF NOISE REDUCTION IN GAS PATHS OF BOILERS DURING CONDENSATION OF WATER VAPOR FROM FLUE GASES

Abstract

An important characteristic of noise silencers, which determines the effectiveness of their use, in addition to reducing the noise level and the pressure losses they create, is the operational resource. Short-term unfavorable operating modes of boilers are possible, in which condensation of water vapor on the walls of flues through which flue gases are evacuated to the environment is possible. Condensation in the gas path leads to corrosion of the metal of the flues, as well as noise silencers. The article lists recommendations for the design of noise silencers installed in the gas paths of boilers operating under conditions of possible condensation of water vapor from flue gases. The introduced silencers of noise of gas paths of boilers which not only reduce noise highly effectively, but also allow to work in difficult operational conditions are given.
