Removal of dust from flue gas at elevated temperatures and pressures. Roeggasrensning for stoev ved hoej temperatur og hoejt tryk

Abstract

Several new coal-based power generation systems are now ready for commercial application. Especially Integrated coal Gasification with combined Cycle (IGCC) and pressurized Fluidized Bed Combustion possess the potential for reducing emissions of SOx, NOx and particulates compared to conventional technology. In addition to this a decrease in heat-rate is possible. However, the decrease in heat-rate is dependant on the temperature of which the removal of particulated and gaseous pollutants takes place. Using state-of-the-art technology this temperature is 25-40 deg. C, but the efficiency improvement will only be substantial if the temperature can be raised to 400-500 deg. C or more. The coal gasification, which is the heart of an IGCC-system, can be caried out in a number of ways. Since the hot gas clean-up equipment (HGCU) to some extent is dependant on the gasification technology used, a description of the leading coal gasification systems is given. It is concluded that special interest should be given to gasifiers of the entrained flow type. The aim is to develope a HGCU-system for the removal of gaseous pollutants as well as particulate matter. The operating principles and stage of development of the competing technologies for dust removal at high temperature and pressure are  More>>
