Abstract

This study deals with the analysis of possibilities of removing of undesirable sticky liquid droplets contained in process waste gas (PWG) stream before entering o tubes of a tube bank heat exchanger (gas preheater), which is a part of gaseous wastes incineration unit. PWG is being preheated by high-temperature flue gas. Presence of the liquid droplets in the PWG in combination with the specific geometry of existing preheater containing stagnation zones on the entry to tube-side of preheater resulted to extensive fouling of tube-side of preheater by deposits. The aim of the study is to identify suitable way of removing liquid droplets from the PWG stream before preheater and to analyse possibilities of design of suitable separation equipment within the frame of spatial limitations and process and operating potential of the gaseous wastes incineration unit.
