Dual sensor combustion system

A dual sensor combustion system, wherein the dual sensor combustion system in its interior has a gas flow passage from an air inlet to a smoke exhaust port, the dual sensor combustion system comprising:

• 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 signal output end of the first pressure sensor assembly being connected to the control unit;
• a second pressure sensor assembly that detects a second pressure signal of fuel gas conduit, a signal output end of the second pressure sensor assembly being connected to the control unit;
• 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;
• 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.
