The high-end gas fired Forehearth developed by Sanjin adopts advanced heating and 

cooling control methods.

Key Technology

-The distributor adopts a direct cooling method with crown design while other zones adopts Indirect Cooling

-Indirect Cooling for each Forehearths

-The Cooling Zones adopts the Indirect Cooling mode of Emhart 640 (patented applied), which has good effect for both side heating and middle area cooling

-Stable and accurate flow control natural gas/air mixing system, automatically and accurately adjusting the natural gas/air mixing ratio

-The new manifold pressure feedback ensures higher control accuracy and energy efficiency

-PLC control system is used for the processing of data from Forehearths and Distributor with strong comprehensive function, convenient temperature adjustment of configuration interface, comprehensive display of items, and direct access to enterprise information management system.

Main Technical Specification
