3 Terms and Definitions
The following terms and definitions apply.
3.1
Furnace safeguards supervisory system (FSSS)
When the boiler furnace is extinguished, protect the furnace from explosion (outside explosion and inside explosion) by using the automatic system for monitoring and control. FSSS includes burner control system (BCS is short for burner control system) and furnace safety system (FSS is short for furnace safety system).
3.2
Burner control system (BCS)
Automatic input and cut-off control system in the time of combustion regime monitoring of oil and coal burner and when the safety condition is met
3.3
Furnace safety system (FSS)
If there is any condition that endanger boiler equipments, automatically stopping input of all the fuels and shut down the operating protection system of the boiler
3.4
Principle of independence
If sense printers use redundant configuration, each redundant signal shall be independent starting from the sampling point.
