More Information
Summary:The utility model provides an air leakage prevention device for a hydrogen production reformer and the hydrogen production reformer, relates to the technical field of petrochemical refining, and solves the technical problems that in the prior art, a large amount of air leaks from an expansion gap between a reformer pipe and a furnace bottom plate, and the heat efficiency of the reformer is low. The hydrogen production reforming furnace where the air leakage prevention device for the hydrogen production reforming furnace is located comprises a furnace body and a reforming pipe, the conversion pipe penetrates through a furnace bottom plate of the furnace body, an expansion gap exists between the circumferential outer wall of the conversion pipe and the furnace bottom plate, and the air leakage prevention device for the hydrogen production conversion furnace can be arranged between the conversion pipe and the furnace bottom plate and at least can prevent air outside the furnace body fromflowing into the furnace
