In addition,heavy metals such as mercury, lead and chromiumare removed by acid gas scrubbers. By the way, thebottom ash from the incinerator is non-hazardous.Incineration is a continuous process. In a moving grateincinerator, waste enters at one end and ash leavesat the other end. The heat is transformed into steam,which drives the turbine. The flue gases are cooledand then pass through the flue gas Cleaning system.This surprises some people, but there aren't the sameconcerns about pollution now that emission controlis better.
It is convenient for the reception of waste tosite incinerators in cities. Also the heat can be utilisedlocally for space heating and electricity generation.Moreover, the heat can be used for increasedelectricity generation, for air-conditioning in summeror space heating in winter.I hope this helps.Best,Karl1 Statements4 g8Of course, people are worried about pollution, but7 Reports12315dBecause hot water can be extracted from theunderground reservoirs.It comes from 13 production wells at Nesjavellir.It travels in a transmission pipe (27 km long with adiameter of 90 cm).It contains a mineral-rich saline solution which blocksthe pipes.
