Description
Technical field
The utility model belongs to technical field of burner, and concrete can not make the liquid-fuel burner of liquid fuel gasification combustion and the liquid fuel burner tool of this burner of employing under pressurized conditions for a kind of.
Background technology
Alcohol radical liquid fuel is the alternative energy source of a kind of economy, cleaning and environmental protection, and because alcohol-group fuel is in a liquid state at normal temperatures and pressures, the transportation storage is all more convenient, than liquefied petroleum gas, natural gas safety, and the burning smoke dust.Because alcohol-group fuel is liquid fuel, thus the alcohol radical liquid fuel that can not burn with the stove and accessory of existing liquefied petroleum gas and natural gas, and the special furnace set of necessary application alcohol radical liquid fuel.
Use at present the combustion technology of alcohol radical liquid fuel also to be among development, the kind of the alcohol radical liquid fuel burner that has appeared on the market is a lot, but is all to adopt the liquid fuel atomization combustion technology basically.Yet, because alcohol radical liquid fuel is a kind of low calorie fuels, adopt the spray burning mode can not efficient burning to it, cause heat utilization efficiency low, also must use air blast combustion-supporting, incomplete combustion, both wasted energy, contaminated air, therefore, adopt liquid fuel atomization combustion system and improper to alcohol radical liquid fuel again.
For low-calorie alcohol radical liquid fuel, best combustion system is gasification, and combustion, and gasification, and combustion can reach completing combustion, and is energy-efficient.At present adopt the stove and accessory of gasification, and combustion technology to occur on market for a few of liquid fuel, but these gasified combustion stoves need to pressurize to fuel, require fuel-supplying pressure minimum in the 0.1MPa left and right, even reach even higher to 0.6MPa, the requirement of the pressurization technology of fuel and pressue device has been limited the range of application of this class combustion technology stove.
also there are some problems in the gasification, and combustion technology of using at present on the other hand, as complicated in gasification installation, gasify unstable, gasification zone liquid, gasifier and nozzle thereof easily produce the defectives such as carbon distribution obstruction, therefore stability and the durability of the gasified combustion apparatus of liquid fuel all have much room for improvement, so for many years, the alcohol-based liquid fuel gasification combustion furnace tool fails to obtain due development, most type alcohol-group fuel stoves still rest on the backward state of the direct burning of liquid and spray burning, not only need to configure air blast, and efficiency of combustion is low, both wasted fuel, contaminated air again.
In view of this, the utility model is intended to explore a kind of with no pressure gasification liquid fuel burner and combustion stove, this with no pressure gasification liquid fuel burner can be realized the gasification, and combustion of liquid fuel under non-pressurized condition, and also has advantages of burning highly effective, complete, the simple in structure and good stability of gasification.
Summary of the invention
The technical problems to be solved in the utility model is to propose a kind of with no pressure gasification liquid fuel burner and combustion stove, this with no pressure gasification liquid fuel burner can be realized the gasification, and combustion of liquid fuel under non-pressurized condition, and also has advantages of burning highly effective, complete, the simple in structure and good stability of gasification.
Realize above-mentioned technical purpose, at first the utility model has proposed a kind of with no pressure gasification liquid fuel burner, comprise the liquid fuel gasification cup, described liquid fuel gasification cup is provided with the liquid fuel gasification chamber of upper end open, the middle part of described liquid fuel gasification chamber is provided with the heat pipe that extends towards its upper end, be provided with the fire cover that is positioned at upper end open place, described liquid fuel gasification chamber between described heat pipe and described liquid fuel gasification chamber, be provided with the vaporising fuel outlet on described fire cover and/or between fire cover and liquid fuel gasification chamber;

Further, the height of described overfall is less than or equal to the height of described liquid fuel entrance, and the height of described overfall is higher than the bottom surface height of described liquid fuel gasification chamber.
Further, described fire cover is sleeved on described heat pipe, and the outlet of described vaporising fuel is for being arranged on the annular gap that also is used for overflowing vaporising fuel between described fire cover outward flange and described liquid fuel gasification chamber interior walls.
Further, described fore-warmer tank is around described one week of liquid fuel gasification chamber outer wall.
Further, the height of described heat pipe is higher than the height of described liquid fuel gasification chamber.
Further, the aluminum liquid fuel gasification cup of described liquid fuel gasification cup for adopting metallic aluminium to make.
The utility model has also proposed a kind of with no pressure gasification liquid fuel combustion stove, comprise with no pressure gasification liquid fuel burner as above, base and cooker racks, described cooker racks mounts cover on described base, described base is provided be used to the burner mount pad that described with no pressure gasification liquid fuel burner is installed, on described cooker racks, with the corresponding burning through hole that is provided with of described with no pressure gasification liquid fuel burner, the outer rim of described burning through hole is provided with the pan mount pad for placing cooker.
The beneficial effects of the utility model are:
with no pressure gasification liquid fuel burner of the present utility model, by the liquid fuel within vaporizer, fore-warmer tank is set outward, before igniting, liquid fuel enters liquid fuel gasification chamber and overflow to fore-warmer tank by being arranged on liquid fuel inlet tube on the liquid fuel entrance, light the liquid fuel in fore-warmer tank, utilize the radiations heat energy heated liquid fuel vaporizer of combustion flame in fore-warmer tank, make and be positioned at the indoor liquid fuel gasification of liquid fuel gasification, liquid fuel after gasification is through vaporising fuel outlet ejection burning, and heating heat pipe, heat pipe is passed to liquid fuel gasification heating indoor liquid fuel with heat, make liquid fuel continue gasification, guarantee that fluid combustion can continue to carry out, because the indoor liquid fuel of liquid fuel gasification after igniting constantly gasifies, liquid fuel no longer overflow enters fore-warmer tank, after the liquid fuel combustion in fore-warmer tank is complete namely from horizontal blanking,
Be the burning crater of liquid fuel combustion due to the vaporising fuel outlet, and be located immediately at the top of liquid fuel gasification chamber, the indoor air pressure of liquid fuel gasification is less, it is less that to be liquid fuel enter the resistance of liquid fuel gasification chamber by the liquid fuel inlet tube, only need to make liquid fuel flow to voluntarily the liquid fuel gasification chamber by the flame regulating valve door a little more than the air pressure of liquid fuel gasification chamber, therefore need not for liquid fuel, pressue device to be set, simple in structure, with low cost, be convenient to marketing and use;
Because liquid fuel is realized gasification by the burning radiation heat, the heat of heat pipe transmission is directly proportional to the size of combusting firepower, so when firepower is regulated, no matter big and small fire all can not produce vaporizer underheat or superheating phenomenon, can reach the burning that is gasified totally of liquid fuel, can not produce the carbon distribution phenomenon by the liquid fuel within vaporizer again, improve the reliability of burner.
Be set to annular gap between fire cover and liquid fuel gasification chamber by vaporising fuel outlet, rather than adopt traditional form of offering aperture on fire cover, this vaporising fuel outlet is difficult for because producing foreign matters from being blocked, carbon distribution is occasionally arranged, also can discharge smoothly in combustion process, can effectively reduce rate of breakdown.
