Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of heating equipment, in particular to an energy-saving and emission-reducing fuel heating device with an air volume regulating structure. Background Art
[0002] At present, heating equipment mainly includes electric load heating equipment and fuel heating equipment. Among them, fuel heating equipment includes gas heating equipment and oil heating equipment. Oil heating equipment mainly uses kerosene, diesel, bio-oil, etc. as fuel, and its structure includes a fuel tank filled with kerosene, diesel, bio-oil, etc., an atomizer, a nozzle, a combustion chamber, and a fan; the fuel is transported to the atomizer through an oil pipeline for atomization, and then the generated oil and gas are sprayed into the combustion chamber from the nozzle at high speed through the nozzle. At this time, the fan is running, blowing air into the nozzle from the nozzle, so that the air is pre-mixed with the oil and gas in the nozzle, and then enters the combustion chamber for ignition and combustion by the ignition needle. However, when the oil heating equipment in the prior art mixes air with oil and gas through the fan, its wind speed and oil and gas are in a relatively constant state of rapid mixing, and the pre-mixing effect is not good. In this way, when the air and oil and gas enter the combustion chamber and burn, the hot gas will be quickly discharged, so that the oil and gas will not burn fully, resulting in low combustion efficiency, increased fuel consumption but cannot obtain a good heating effect. Therefore, it is necessary to reasonably adjust the wind speed according to different types of oil and gas, and the adjustment structure in the prior art generally controls the air intake volume by pulling the size of the damper through an adjustment handle with a screw. Since a spring is provided between the adjustment handle with a screw and the damper, there is an unstable elastic buffer between the screw and the damper. Therefore, when the damper is moved and adjusted, the damper size may be inaccurate and the adjustment handle may become stuck when controlling the damper adjustment, making the adjustment inconvenient.
