Abstract
Contents of nitrogen compounds in the product gas of peat and wood gasification in fixed bed were measured at two gasification heating stations. A significant amount of ammonia, NH3, formed in peat gasification, whilst in wood gasification its amount was insignificant. Part of the fuel nitrogen was converted to hydrogen cyanide, HCN, which formed in wood gasification nearly as much as in peat gasification despite the higher nitrogen content of peat. The proportion of nitrogen bound in the organic compounds of tar in the total nitrogen of the fuel was significant. The moisture content of peat had no essential effect on the amounts of nitrogen compounds formed in the product gas. The output of the plant has only an insignificant effect on the amount of gas nitrogen compounds, whilst the effect on NOX emissions was stronger.
