Dual sensor combustion system
The embodiments of the present application disclose a dual sensor combustion system. The dual sensor combustion system comprises: a combustor; a stepless speed regulating fan that supplies air for the combustor; a fuel gas conduit that is in communication with the combustor; a proportional valve provided on the fuel gas conduit; a control unit electrically connected to the stepless speed regulating fan and the proportional valve; a first pressure sensor assembly that detects a first pressure signal of the gas flow passage; a second pressure sensor assembly that detects a second pressure signal of the fuel gas conduit; a storage that stores a correspondence relationship between a first target pressure signal of the gas flow passage and a second target pressure signal of the fuel gas conduit; and the control unit controlling at least one of the stepless speed regulating fan and the proportional valve based on the first pressure signal, the second pressure signal and the correspondence relationship.
