Embodiment
[0017] Example: see attached figure 1 , figure 2 As shown, an air flow feedback negative pressure combustion-supporting smoke exhaust system of a biomass pellet burner, the furnace 5 of the burner communicates with the fuel bin 4, including a controller, a heat exchanger 2, a smoke exhaust pipe 3, a cooling Air duct 6, combustion-supporting air duct 8, fan and air flow sensor 9, the combustion-supporting air duct 8 communicates with the furnace 5, and air enters the furnace through the combustion-supporting air duct 8 to burn fuel.
[0018] The air flow sensor 9 is installed at the air inlet of the combustion air duct 8, such as figure 2 As shown, and connected with the controller, the air flow sensor 9 is used to detect the air flow entering the combustion air duct 8 through here, and convert the flow signal into a corresponding voltage signal.
[0019] The controller is also connected to the fan, and the controller stores the combustion-supporting air flow required by th...

The invention relates to an air flow feedback-type negative-pressure combustion smoke evacuation system of a biomass particle combustor. A hearth of the combustor is communicated with a fuel bin. The air flow feedback-type negative-pressure combustion smoke evacuation system of the biomass particle combustor comprises a controller, heat exchanger, smoke evacuation pipelines, cold air pipelines, a combustion air pipeline, a fan and an air flow sensor. The combustion air pipeline is communicated with the hearth; the air flow sensor is arranged in the combustion air pipeline; and the controller is respectively connected with the air flow sensor and the fan. According to the air flow feedback-type negative-pressure combustion smoke evacuation system of the biomass particle combustor provided by the invention, the air flow at the position that the air flow sensor is located is acquired by the air flow sensor, a flow signal is converted into a voltage signal, the voltage signal transmitted by the air flow sensor is received by the controller, and the rotating speed of the fan is adjusted in real time according to the combustion state of a complete machine, and therefore, the flow of combustion air is controlled so as to achieve the best combustion effect.
Description
technical field [0001] The invention relates to an air flow feedback negative pressure combustion-supporting smoke exhaust system of a biomass particle burner, which is mainly used in burners using biomass particles as fuel, including fireplaces, boilers, heaters and the like. Background technique [0002] At present, in combustion equipment such as fireplaces and boilers that use biomass particles as fuel, a fixed negative pressure combustion-supporting smoke exhaust control system is generally used. The required amount of combustion-supporting air, and the collected data is stored in the control system. When the combustion equipment is working, the system calculates the required amount of combustion-supporting air according to the actual feeding amount at that time and automatically sets the corresponding fan speed. Meet the needs of combustion equipment. This control system seems reasonable, but in actual use, due to the different settings of the smoke exhaust pipe, such...
