    • A catalytic combustion heater for a heat exchanger (1) which has a fuel gas flow passage (11), and a plurality of tubes (5) provided in the fuel gas flow passage, formed so as to have a fluid to be heated flow therein, and having catalyst support fins (51) fixed to an outer surface thereof, and which is formed so that the object fluid is heated by an oxidation reaction of the fuel gas. A control unit (6) is adapted to judge that a flow rate of the object fluid is low until the temperature of the object fluid detected by temperature detector (8) provided in the vicinity of an outlet of an object fluid flow passage (55) has not exceeded a predetermined level, for example, a boiling point thereof, to restrain the heat transfer to the interior of the tubes (5) and increase temperature of the fins (51) early to a catalyst activating level. Said control unit is also adapted to increase the flow rate of the object fluid to a specific level after the temperature thereof has exceeded the boiling point thereof, to promote the heat transfer to the object fluid, whereby a desired high-temperature gas is obtained with a short starting time as the attainment of unnecessarily high temperatures of the fins (51) and tubes (5) is prevented.

    • The present invention relates to a dental water heater (10). The water heater (10) has a columnar body (11), and the body includes heating means (12) extending in the axial direction of the body, and a plurality of layers of water channel sections (13-16) arranged around the heating means (12). Each of the water channel sections (13-16) spirally extends in the axial direction of the body (11). The adjacent pairs of the water channel sections (13-16) are communicated either at upper or lower end portions thereof so as to together form a whole water channel. The whole water channel has an inlet and an outlet for water to be heated, so that water is supplied through the inlet, passed through the entire length of the whole water channel, and taken out as warmed water through the outlet.

    • 用于具有燃料气体流动通道(11)的热交换器(1)的催化燃烧加热器以及设置在燃料气体流动通道中并且形成为具有待加热流体的多个管(5)在其中流动 并且具有固定在其外表面上的催化剂载体翅片(51),并且其形成为使得通过燃料气体的氧化反应加热目标流体。 控制单元(6)适于判断目标流体的流速低,直到由设置在目标流体流动通道(55)的出口附近的温度检测器(8)检测到的目标流体的温度为止, 没有超过预定的水平,例如其沸点,以限制向管5内部的热传递并且将翅片51的温度提前提高到催化剂活性水平。 控制单元还适于在目标流体的温度超过其沸点之后将目标流体的流速增加到特定水平,以促进向目标流体的热传递,由此获得期望的高温气体 因为防止了翅片(51)和管(5)达到不必要的高温,所以启动时间很短。

    • Bei diesem Durchlauferhitzer insbesondere für Maschinen zur Herstellung von Brühgetränken ist zur Optimierung des Wirkungsgrades eine erste Zone starker Wassererhitzung mit einem senkrechten Einlaufstück (3) mit anschließendem Krümmungsbogen (4) des Wasserrohres (1) vorgesehen. Daran schließt sich eine zweite Zone längerer Heizleistung mit Erhitzung des Wassers bis zum Siedepunkt an, und zwar in einem liegenden, zum Auslauf hin jedoch leicht ansteigenden Rohrstück (5) des Wasserrohres (1). Eine dritte Zone starker Wassererhitzung mit Dampfblasenbildung zur Erzielung des gewünschten Förderstromes schließt sich im Endbereich des Rohrstückes (5) und einem angrenzenden Krümmungsbogen (6) an. In einem daran anschließenden senkrechten Auslaufstück (7) als vierter Zone findet nur noch eine Wassernacherhitzung bei geringer Heizleistungszufuhr statt.
