Abstract:

The design thought and basic principle of leakage detection logic of burner management system for gasfired boiler, which had been designed in accordance with the standard NFPA 852001 issued by the National Fire Protection Association of America, were introduced. The twostage detection process was used in this detection logic. It was proved by practical application that the design of the twostage leakage detection logic is rational and reliable.

Key words: burner management system, leakage detection in two-stage, logic design
