Abstract

The invention provides a temperature control system and method of combustion equipment. The temperature control system of the combustion equipment comprises a thermocouple, a temperature control circuit, a master controller, a pressure sensor and a combustor. The thermocouple detects the current temperature in a drying room. The temperature control circuit receives the current temperature sent bythe thermocouple and sends the current temperature to the master controller. The pressure sensor detects a current pressure signal of the combustor. The master controller receives the current pressuresignal sent by the pressure sensor and the current temperature sent by the temperature control circuit, the current pressure signal is compared with a preset pressure signal so that a flame signal can be obtained, the flame state is judged according to the flame signal, if the flame state indicates that a flame exists, the current temperature is compared with the preset temperature, and heating of the combustor is controlled according to the comparison result. The state of the flame in the combustor can be reflected through the pressure signal, the continuity of the combustion process is guaranteed, the combustor is accurately controlled, and the effect of finished products of textile fabrics is improved.

Description

technical field [0001] The invention relates to the technical field of combustion equipment, in particular to a temperature control system and method for combustion equipment. Background technique [0002] Commonly used textile equipment in the textile industry includes setting machines, steaming machines, printing machines and dryers, etc. These textile equipment work through burner heating. [0003] Specifically, during initial ignition of the burner, shortly after fuel is introduced into the burner, a stable flame is created and maintained in the burner to initiate and maintain combustion in the burner. During steady-state and transitional operations, the fuel-air mixture is continuously adjusted to optimize thermodynamic efficiency and reduce undesired emissions of nitrogen oxides, carbon monoxide, and other combustion by-product gases. Adjustments to the fuel-air mixture can create flame instabilities that can lead to extinguishment or loss of flame conditions in the c...
