摘要： PROBLEM TO BE SOLVED: To provide a liquid fuel combustion apparatus which realizes low power consumption, a simple structure, and short preheating time. SOLUTION: The apparatus is provided with a secondary vaporizing portion 42 having a heating means 43 and a primary vaporizing portion 41 having no heating means. Since only secondary vaporizing portion 42 is heated by means of the heating means 43 built into the secondary vaporizing portion 42 at the time of ignition, the preheating period when the secondary vaporizing portion 42 reaches a prescribed temperature at which the fuel is gasified can be shortened. Also, when combustion is initiated with the secondary vaporizing portion 42, combustion heat of flame is received with a heat receiving portion 50, and the primary vaporizing portion 41 is heated up to the prescribed temperature at which the fuel is gasified. Thereby, the heating means 43 becomes unnecessary during the combustion in the primary vaporizing portion 41. Consequently, the power consumption can be reduced and the structure of the combustion apparatus becomes simple.
摘要翻译：要解决的问题：提供实现低功耗，简单的结构和预热时间短的液体燃料燃烧装置。解决方案：该装置设置有具有加热装置43和不具有加热装置的初级蒸发部分41的二次蒸发部分42。由于只有二次汽化部分42在点火时通过内置于二次汽化部分42中的加热装置43被加热，所以可以缩短二次汽化部分42达到燃烧气化的规定温度的预热时间。此外，当用二次汽化部分42开始燃烧时，用热接收部分50接收火焰的燃烧热，并且将主蒸发部分41加热到燃料气化的规定温度。由此，在一次汽化部41的燃烧时，加热装置43变得不必要。因此，可以降低功率消耗，并且燃烧装置的结构变得简单。

摘要： PROBLEM TO BE SOLVED: To efficiently subject garbage to a drying treatment in a short time, preventing malodor by decomposing generated odorous gases. SOLUTION: The apparatus is provided with a combustion part 3, a drying part 1 drying the garbage using heat generated by the combustion part 3, a deodorizing part 15 deodorizing gases after dried in the drying part 1 and a passage connecting the combustion part 3, the drying part 1 and the deodorizing part 15, and the deodorizing part 15 is constituted of a heat exchanger for deodorization 18 comprising heat exchanging pipes for deodorization 19 heated by heat-exchanging with combustion gases. Installation of a heat-transfer accelerating means 17 or the heat exchanger for deodorization 18 and heat treatment of the combustion gas via the heat exchanger for deodorizing 18 can quickly and completely deodorize the combustion gas even when retention time of the combustion gas in the heat exchanger for deodorization 19 is shortened by increasing the flow rate of the gas.

摘要： PROBLEM TO BE SOLVED: To provide a garbage disposer capable of preventing deterioration of garbage and generation of poisonous gas in the case of drying garbage. SOLUTION: Combustion gas and air for drying are mixed in a mixing part 26 and furthermore one part or all parts of the mixed combustion gas introduced into a drying treatment part for drying and treating garbage are made to a circulating gas. Thereby, garbage can be dried by a plenty of mixed combustion gas which is comparatively low temperature in comparison with only combustion gas and has low partial pressure of vapor. Drying of garbage at low temperature is enabled and garbage is not deteriorated and fine particles such as dust generated from garbage are not reheated by a burner 21 and therefore such a fear is prevented that poisonous gas is generated.

摘要： PROBLEM TO BE SOLVED: To increase a variable range and improve the proportional controllability of n amount of combustion. SOLUTION: A combustion amount control from a maximum amount of combustion to an intermediate point is performed by varying pulse frequency set to a maximum value under with a disadvantageous influence is not applied to the mechanical responsiveness of a pulse pump 12 to pulse frequency under which no influence is applied to a combustion state by making a pulse width constant. Further, the combustion amount control is performed by varying the pulse width with the pulse frequency made constant. The variation of initial velocity of a plunger and the nonlinear variation of the amount of combustion upon change of the pulse width are corrected by pulse voltage. Thus, the amount of combustion can be proportionally varied. Simultaneously, the variable width from the maximum amount of combustion to the minimum amount of combustion can be also increased.

摘要： PROBLEM TO BE SOLVED: To reduce the amount of nitrogen oxides contained in the exhaust combustion gas discharged from combustion equipment. SOLUTION: This combustion equipment is provided with proximate air injection nozzles 29 near burner ports 22 and flame stabilizing sections 30 above secondary air passages 25 on the opposite side through the injection nozzles 29 and burner ports 22. In addition, since secondary air can be brought into collision with flames from the injection nozzles 29, the flames can be cooled and the temperatures of the flames can be lowered. Consequently, the occurrence of nitrogen oxides can be prevented. In addition, since the flames can be stabilized by means of the flame stabilizing sections 30, the occurrence of carbon monoxide and irritating smells resulting from the lowered temperatures of the flames can be prevented.

摘要： PROBLEM TO BE SOLVED: To enable combustion equipment on the thick and thin fuel combustion method to obtain normal combustion by suppressing the recondensation of gasified liquid fuel. SOLUTION: In this combustion equipment, a thick-side opening 45 which enables a thick premixed gas generating chamber 39 to communicate with a thick burner port 23, a thin-side opening 46 which enables the chamber 39 to communicate with a thin premixed gas generating chamber 44, and the chamber 44 are provided in a heat transfer means 42 which returns the heat of flames to a gasifying means 37 and the recondensation of gasified fuel is prevented by suppressing the temperature drop of the fuel until the fuel reaches the burner ports 23 and 25. Therefore, the fuel can be burnt at a desired excess air ratio and the occurrence of NOx, CO, HC, soot, etc., can be suppressed. At the time of shutting-off this equipment, in addition, the occurrence of an offensive smell can be suppressed, because no condensed fuel is left.

摘要： PROBLEM TO BE SOLVED: To obtain a domestic kerosene combustor in which thermal deformation due to backfire to the upstream side of a burner port or temperature rise thereof can be prevented. SOLUTION: The combustor is provided with an air regulation means 36 for varying the air supply distribution ratio between a thick burner port 19 and a thin burner port 20. When combustion is varied to decrease, the air regulation means 36 varies the air supply distribution ratio between the thick burner port 19 and the thin burner port 20 to prevent the flame from adhering to the thick burner port 19 thus preventing backfire and thermal deformation.
