Abstract
A process for producing fuel gas and for carrying out a metallurgical process includes providing first and second process stages. In the first process stage, biomass is reacted with an oxygen-containing gas so as to obtain a fuel gas containing at least one of carbon monoxide, hydrogen, carbon dioxide and steam. The fuel gas is cooled to a temperature in a range from 300 to 600° C. The cooled fuel gas is subjected to a solids separation. In the second process stage, the fuel gas after the solids separation is directly supplied to at least one burner of the metallurgical process, the temperature of the fuel gas being maintained above the condensation temperature of tar and within the range from 300 to 600° C. by supplying heat.
