A combustion heater includes an inner tube having a supply passage for combustion gas in an inner portion, and an outer tube disposed to provide a separated combustion space in an outer periphery of the inner tube. A hole part for ejecting the combustion gas is formed on a tube wall of the inner tube and combustion gas is ejected with ejection characteristics such that circulating flow is formed on the periphery of a stagnation point. According to this combustion heater, a stable flame can be formed without increasing costs and the heating efficiency can be improved.

A combustion heater (1) comprises an inner tube (20) having a supply passage (21) for a combustion gas (G) therein and an outer tube (10) disposed around the outer periphery of the inner tube with a combustion space (30) interposed therebetween. A hole part (24) for jetting the combustion gas is formed in the wall of the inner tube. A radiation promoting surface (20B) is formed on the outer periphery of the inner tube. By the structure, the excessive heating of the inner tube is suppressed, and the heating efficiency of the combustion heater is increased.
摘要:
A first flow passage (R1) in which uncombusted gas (G1) that contains a combustible fuel is injected from a nozzle hole that is smaller than the flame quenching distance at a flow speed to thereby enable flame maintenance is combusted, and thereby enables flow of combustion gas (G2) resulting from such combustion, and a second flow passage (R2) formed about the first flow passage and enabling flow of uncombusted gas supplied through the nozzle hole are provided. According to the present invention, the combustion chamber in a heating apparatus that heats a liquid to be heated is be reduced in size, the flame in the combustion chamber can be stabilized, and energy efficiency can be improved.

The present invention is to provide a sample separation instrument used in a sample separation apparatus which includes: holding means for holding a first medium supporter which supports a first medium; and driving means for moving fixing means or the holding means in a direction parallel or perpendicular to a plane whose sides extend in the first direction and in the second directions. The sample separation instrument includes an insulator for storing a second medium which allows a sample separated in the first medium in the first direction to be further separated in the second direction different from the first direction, wherein: the insulator includes a first opening and a second opening each of which defines the second direction in which the second medium is electrified, and the second opening has a shape which allows the first medium containing the separated sample to be attached to the second medium along the first direction. The present invention realizes automation of the two-dimensional electrophoresis to enhance the convenience of the two-dimensional electrophoresis, to less depend on the operator's skill, and to enhance the reproducibility of the electrophoresis result.
