A method of marking on sheet metal includes the following steps: preparing marking information in digital format; transmitting the marking information to a marking system's control unit also having a system for driving the sheet metal; a system for braking the sheet; and a marking head; and inserting the sheet metal into the braking system and into the drive system. The method further includes the steps of exerting a drive force on the sheet metal in a drive direction; exerting a braking force on the sheet metal opposing the driving force, so as to tension and flatten the sheet metal; and marking the marking information on the tensioned sheet metal using the marking head, set in a marking plane.

A system is disclosed. The system includes a boiler setting system, a heating system, a burner, an inner layer temperature measurement system and an outer wall temperature measurement system, where the boiler setting system includes four vertically arranged, interconnected bottom supported heavy walls and/or sectional supporting water cooled walls; the bottom supported heavy wall includes a refractory brick layer, a first insulation layer and a machine-made red brick layer in order from the inside to the outside; the sectional supporting water cooled wall includes a second insulation layer, an air interlayer and a steel plate in order from the inside to the outside; the heating system includes a membrane wall and a smooth tube; the membrane wall is fixed inside the bottom supported heavy wall; the smooth tube is fixed inside the sectional supporting water cooled wall; the burner is fixed on the inside bottom of the boiler setting system.
