| 摘要 |
The invention relates to a reactor (1) for synthesizing HCl from chlorine and hydrogen, including a bottom so-called furnace portion (7) and a top so-called convector portion (8), said furnace (7) comprising, in the bottom portion thereof, a burner (2) that is supplied with chlorine and hydrogen so as to form gaseous HCl, said convector (8) being coaxially arranged above said furnace (7), and said convector (8) comprises a plurality of tubes (31) contacting a heat-transport fluid. The reactive gases of said furnace (7) pass through said tubes (31), and said heat-transport fluid flows in the space between said tubes (31). A perforated tubular plate (38), onto which the tubes (31) of the convector (8) are attached, is arranged between the furnace (7) and the convector (8). Said reactor (1) is characterized in that all the inner walls of said reactor (1) contacting the gaseous HCl are made of a metal alloy and in that, within said furnace (7), at least a portion of the inner surfaces of the walls contacting the gaseous HCl is made of an alloy containing at least 20 wt % of nickel. |
