| 简介 |
Objective of the process according to the invention it is conditioned fuels from biomass and produce combustible material, and thereby simultaneously takes place on the one hand, a drying by minimizing pollutant freightcorrosion alkali halides the formation during the combustion is suppressed. In a first step the wet biomass is metered in a base, to the existing ammonium as the ammonia release. The biomass is then heated and subjected to a vacuum. This of the biomass is to be withdrawn the ammonia, while the sulfur compounds remain in the biomass. In a second method step the biomass is dried. Through the elevated pH-value " decreases simultaneously the corrosion potential of the biomass with respect to the steel that is used of the dryer. By the presence of alkaline earth ions when using an alkaline earth base are formed during the drying process with the alkaline earth ions compounds, alkali metal chlorides under the combustion conditions have significantly lower volatility than the the. This the chloride concentration in the flue gas and the corrosion of the heat exchanger is severely curtailed significantly cut into pieces. The still contained in the fuel are reacted to sulfur oxides sulfur compounds, the present in the flue gas on the heat exchangers with the oxides form a [...] protective layer. |
