Description

A kind of energy-saving alcohol-based fuel combustor

Technical field

The utility model is related to combustor, more particularly to a kind of energy-saving alcohol-based fuel combustor.

Background technology

Mainly with oil liquefied gas, bavin in the middle-size and small-size thermal device such as Industrial Boiler, kiln, lithium bromide central air-conditioning Oil, fuel oil are as fuel, and not only cost is higher for the fuel of the above-mentioned type, but also carbon discharge capacity is higher, to the seriously polluted of environment. With the further development of clean energy resource, it is desirable to be made using a kind of cleaning, renewable and safe to use fuel Substitute for above-mentioned fuel.

Alcohol-based synthetic fuel is mainly blent by give up alcohol, industrial crude glycol and perfect combustion catalizer of chemical industry.Alcohol radical synthesis combustion Predominant emissions after material burning are small to the pollution of environment for carbon dioxide and water vapour, are a kind of clean energy resourcies, and its valency Lattice are cheap, safe to use, favor by market.At present alcohol-based synthetic fuel gradually diesel oil substitute, oil liquefied gas factory, School, food and drink, hotel etc. use to be used in the place of large kitchen kitchen range.

But since the output thermal power of these thermal devices such as fuel industrial boiler, kiln, lithium bromide central air-conditioning is led to Often requirement needs the burner using relatively high power in the range of 0.35Mw~14Mw.And it is closed currently used for burning alcohol radical Cup type evaporation burner and pressure atomization formula combustor are mainly used into combustor used by fuel.

The manufacture of cup type evaporation burner is at low cost, and this burner mainly relies on fuel heat release spoke in combustion process The heat for being mapped to glass area carrys out evaporated fuel medium, therefore its output thermal power is directly proportional to cup heating surface area and temperature value；By There is the basic limitation of maximum practical dimensions to burner, therefore current this burner is in practical applications in heating device Maximum output thermal power is in 0.029Mw hereinafter, can not be suitable for above-mentioned high-power burner.

Pressure atomization formula combustor mainly relies on machinery to generate pressure by fuel medium spray burning, and output thermal power is high In the maximum output thermal power of cup type evaporation burner, but fail to solve the problems, such as that methanol fuel flameholding is safe.It is pressing During the use of power atomization type combustor, since alcohol-based synthetic fuel needs to absorb a large amount of heat in atomization, lead to fuel Temperature is relatively low before burning after atomization, reaches high value (i.e. close to burning when making atomized fuel flow and combustion air flow velocity Flame propagation velocity) when, the combustion stability of combustor will be decreased obviously, and cause to generate de- fiery phenomenon, burning is influenced when serious The continuous normal operation of machine, which limits the maximum thermal outputs of pressure atomization formula combustor.Therefore, pressure atomization at present The maximum thermal output of formula combustor can only be all designed in 0.035Mw hereinafter, can not meet the condition of high-power burning.

Meanwhile for certain form of alcohol base class synthetic fuel, for example water content is more than 40% industrial waste methanol, by Low in its calorific value, existing combustor is unable to maintain that the continuous normal combustion of its flame at all, thus existing combustor without All alcohol base class synthetic fuels of method burning.

For this purpose, there is Chinese patent Authorization Notice No. CN201680367U to disclose a kind of fuel conveying mechanism and alcohol radical at present Fuel combustion machine, but above-mentioned patent is to provide the front end that firn-jet head extends to out fiery channel, leads to its rear end for cantilevered, It easily shakes during the work time, and then influences fiery precision；Furthermore the flame of above-mentioned patent be cylindricality, flame length It is shorter.

Utility model content
