Technical field
The utility model relates to a kind of kitchen range, particularly relates to a kind of kitchen range that are suitable for the alcohol-group fuel burning, and kitchen range of the present utility model can be realized the abundant gasification, and combustion of alcohol-group fuel.
Background technology
Along with the raising of China's economic development and people's living standard, society is increasing to the demand of clean energy resource, and the development and use of novel clean fuel are imminent, and alcohol radical liquid fuel is that this respect is extremely promising a kind of.
Alcohol-group fuel is the clean energy resource of a kind of cheapness, environmental protection.Because fuel itself contains oxygen, aerobic less during burning, fuel combustion is abundant, is blue flame, does not contain carbon granules in the flue gas, is mainly carbon dioxide and water; The alcohol-group fuel sulfur content is extremely low, and it is also extremely low that burning back flue gas sulphur oxide generates concentration, is one of cleaner burning fuel that is only second to hydrogen.
Alcohol-group fuel can coal, heavy oil, natural gas or living beings etc. are raw material production, and raw material sources are wide, and production technology is simple, technology maturation.There is thousands of families small fertilizer plant in the whole nation, and most factories have ready conditions and utilize the pure method of connection to produce methyl alcohol, produce alcohol-group fuel for undoubtedly the pure method of connection reliable raw material supply channel is provided; Producing alcohol-group fuel is again the important component part of coal liquefaction and living beings production renewable sources of energy technology, and the cost of large-scale production alcohol-group fuel has the extremely strong market competitiveness far below other fuel such as liquefied petroleum gas, natural gas, artificial coal gas.

The 5th class: multistage gasification combustor
Partly form by fuel tank, fuel control, preheated air, main combustion vaporizer, multistage gasifier, auxiliary gasification combustor etc.Liquid fuel is gasified totally through heating step by step in multistage gasifier, becomes 120～500 ℃ combustion gas, enters auxiliary gasification combustor, with high temperature air mixed combustion.The complexity of this burner structure is than inflating adding pressure type more very, and difficulty is fit to the light simple requirement of normal domestic cooking stove.
Domestic preparation research to alcohol-group fuel is carried out more at present; many costs are fit to, the New-type fuel of stable performance constantly comes out; and supporting with it burner developmental research makes little progress; really can make fuel-efficient burning, energy-conserving and environment-protective, simple and practical again, can also not have for the kitchen range of normal domestic market scale promotion and implementation.Fall behind just because of alcohol-group fuel combustion technology research at present and kitchen range designing and manufacturing level, restricted the extensive popularization of this novel clean energy resource of alcohol-group fuel.
