Combustion method and device capable of achieving gasified combustion of alcohol-based fuel on basis of triggering by natural gas and achieving fierce fire

Abstract

The invention discloses a combustion method and device capable of achieving gasified combustion of an alcohol-based fuel on the basis of triggering by natural gas and achieving fierce fire. The deviceincludes an alcohol-based fuel storage tank, an alcohol-based fuel feeding pipe, an oil inlet solenoid valve, a combustion controller, a combustion pump, an ignition wire, a gasified pipe inlet, an ignition needle, a gasifying pipe, a natural gas sprayer nozzle, a gasifying burner, an alcohol-based fuel sprayer nozzle, a gasifying pipe outlet, an alcohol-based fuel discharge pipe, a natural gas solenoid valve, a natural gas feeding pipe, an air chamber, an air inlet and an air blower. In a work starting process of the device, fire power is only supplied by combustion of natural gas and is available once the natural gas is fed in; after the device works for a certain period of time, the alcohol-based fuel enters the gasifying pipe and is gasified quickly and fully burnt under the action ofthe flame of the natural gas after being sprayed out, and the problem that people's eyes sting in a power initiation process cannot occur. Under a special work condition, by starting and increasing the input of the natural gas, the work demands for the fierce fire can be met; after work is finished, the problem that people's eyes are stung by alcohol-based fuel residues cannot occur.

Description

technical field [0001] The invention belongs to the technical field of alcohol-based fuel combustion, and in particular relates to a combustion method and device for starting the vaporization combustion of alcohol-based fuel by non-electrically heated vaporized natural gas and realizing rapid fire. Background technique [0002] Alcohol-based fuel is a liquid fuel mainly composed of methanol mixed with polyols such as ethanol and propanol and alkanes. It is a new type of alternative energy with great development potential that is widely used in hotels, restaurants, canteens, factories, home kitchens, industrial boilers and other places with the characteristics of environmental protection, vaporization temperature of 65°C, high thermal efficiency, and thorough combustion. In the prior art, there are two main types of alcohol-based fuel combustion devices: the first type is alcohol-based fuel atomization combustion type, which is to atomize and spray liquid alcohol-based fuel t...
