Day Tank combustion system
All the main furnace process variables are automatically controlled by precision closed loop controllers. The signals, derived from a comprehensive set of plant sensors, are taken to a central control and instrumentation panel. Manual by-pass switches are available for all variables for setting up or emergency use. From the central control panel it is possible to start and check all the plant.
Day Tank working cycle description
The glass melting furnace Day Tank type has a circular shape and is heated with methane gas through a hot air burner, coming from a steel heating recuperator. The furnace is provided with an automatic combustion system. The flame of the burners works tangent to the circular wall of the furnace, and it runs on the glass surface, following a U trajectory. The draught chimney is placed on a lateral position as regards the working mouth. The working cycle is daily, 24 hours on 24, and it is divided in four different phases.
