Embodiment Construction
[0028] Embodiments of the present invention (hereinafter sometimes referred to as "embodiments") will be described in detail below with reference to the accompanying drawings, but the present invention is not limited to the following embodiments. Appropriate design changes, improvements, and the like can be made based on common knowledge of those skilled in the art.
[0029] Fig. 1 is a side view schematically showing a sintering furnace including one embodiment of a steam reforming device of the present invention, and Fig. 2 is an A-A sectional view of the sintering furnace shown in Fig. 1 . In this embodiment, although the case where a sintering furnace is used as an industrial furnace is demonstrated, it is not limited to this. In this specification, when referring to an industrial furnace, it means an industrially used furnace in which a body to be heated can be placed inside (furnace) and heated, including a sintering furnace, a combustion furnace, and the like. In additio...

Abstract
A steam reforming apparatus (21), which is arranged in an industrial furnace (100) for burning a fuel and firing an article to be fired with the combustion heat of the fuel, and has a low temperature reforming section (23) having a metal reaction tube (25) or a ceramic reaction tube packed with a reforming catalyst for accelerating a steam reforming and a high temperature reforming section (22) having a ceramic reaction tube (24) for causing a steam reforming inside it. The above steam reforming apparatus can be suitably used for recovering a part of the combustion heat (waste heat) of an industrial furnace with good efficiency in response to the temperature range of the heat.
Description
technical field [0001] The present invention relates to a steam reforming device, a steam reforming method using the same, and an industrial furnace, and more particularly, relates to steam reforming by making a part of the combustion heat (exhaust heat) of an industrial furnace consistent with its temperature range and effectively utilizing it. A complete steam reforming device, a steam reforming method using the steam reforming device and performing steam reforming by making a part of the heat of combustion (exhaust heat) of an industrial furnace coincide with its temperature range and effectively utilizing it, and a steam reforming method having the above Industrial furnaces for steam reforming plants. Background technique [0002] Conventionally, industrial furnaces have been used as devices for heating objects to be heated in various industrial fields. In an industrial furnace, heating an object to be heated by burning a fuel containing carbon means generating a high-t...
