Working principle


YJT Gas principle

The motor(1) drives the fan(5) to rotate at high speed, the vacuum detector (2) detects the negative pressure, and the gas solenoid valve opens. The fan inhales the combustion air and the gas at the same time and air and gas are fully mixed in the air-fuel mixer(4) and then are discharged from the nozzle(9). The igniter (3) is discharged by the ignition electrode(7), ignites the combustion gas, the air-gas mixture is burned in the combustion chamber(11), heat generated passes through the lamella(8), and exhausts are discharged from the exhaust pipe to the atmosphere. The lamella (8) absorbs heat and heats the circulating liquid in the heat exchanger(10), and the liquid is discharged under the action of the circulation pump(6).
