摘要： An economizer arrangement particularly suitable for new or retrofit application to existing steam generators provides a water cooled stringer support tube system which can accommodate firing a wide range of fuels with varying characteristics in the steam generator. The economizer arrangement according to the present invention is particularly suited for retrofit applications to large supercritical steam generators. The use of water cooled stringer tube supports allows for higher flue gas temperatures in comparison to conventional non-cooled mechanical economizer supports. These features are provided in a design which fits within the existing economizer envelope of the steam generator.

摘要： The invention as disclosed in the following specification, relates to a heat exchanger, having tubes fitted into plates, that exchange heat from a gas passing thereover to fluids passing through the tubes. The heat exchanger is particularly adaptable to boilers having fire tubes and other types of boilers wherein the heat applied to the tubes is circulated and then exhausted. Prior to exhaust, the heated gas is passed over the plates in a duct. The tubes in the plates are used to pick up the heat from the exhaust gases by means of the feed water passing through the tubes, or the tubes can be used to directly heat other fluids, such as oil and service hot water. A damper is placed over the normal exhaust gas flue in conjunction with a second damper or duct control system whereby an exhaust fan on the downstream side of the heat exchanger duct provides a constant draw to allow the boiler to operate within its normal pressure ranges. An optimum exchange relationship between the tubes and the plates effectuates the proper heat transfer for the respective flow rates and temperature involved by means of employing a specially configured tube pitch within the plates. The exchanger is controlled by a series of electrical controls for providing adequate exhaust damping and flow rates.
摘要翻译： 以下说明书中公开的发明涉及一种热交换器，其具有装配到板中的管，其将热量从通过其的气体与通过管的流体交换。 热交换器特别适用于具有消防管和其他类型的锅炉的锅炉，其中施加到管的热量循环然后被排出。 在排气之前，加热的气体在管道中通过板。 板中的管用于通过通过管的给水从废气中吸收热量，或者可以使用管直接加热其它流体，例如油和服务热水。 阻尼器与第二阻尼器或管道控制系统结合放置在正常废气烟道上，由此在热交换器管道的下游侧的排气风扇提供恒定的抽吸以允许锅炉在其正常压力范围内操作。 管和板之间的最佳交换关系通过在板内采用特殊配置的管间距来实现相应的流速和相关温度的适当传热。 交换器由一系列电气控制器控制，以提供足够的排气阻尼和流量。
