Description

Compound oil burner

technical field

The utility model belongs to the technical field of combustion machines, in particular to a composite oil combustion machine.

Background technique

The burner is a device that mixes fuel and air reasonably to make the fuel ignite stably and burn completely. The burner includes a fan, an oil gun, an oil pump and an air pump; the oil gun of a traditional burner is a mechanical atomizing oil gun, which mainly relies on the pressure of the oil pump to pump high-pressure oil into the oil pipe of the oil gun, and sprays it out through the nozzle and the fan. The injected air is mixed; the structure of the traditional oil gun can only use light diesel oil, and the price of light diesel oil is relatively high; because the pressure of the oil pump is required to pump the high-pressure oil into the oil pipe of the oil gun, the oil pressure required by the oil pump is high, resulting in The oil pump is easily damaged and worn, which reduces the oil pressure output by the oil pump and affects the effect of atomization and combustion.
