摘要： This invention relates to combustion apparatus incorporating a balanced draught system comprising a forced draught fan (6) for delivering combustion air to a burner section (7) and an induced draught fan (9) for extracting effluent gases from the burner section (7). A drive mechanism (10) operates the fans. In order to improve the efficiency of the apparatus and simplify control of gas flow therethrough, according to the invention the fans (6, 9) are operatively coupled such that adjustment of both is simultaneous, maintaining a predeterminable relationship between their outputs. This enables system characteristics to be matched almost exactly. Coupling of the drive mechanism (10) to the respective fans can be by conventional means, but fan control is preferably accomplished by speed variation, electric motors using a frequency converter system.

摘要翻译：本发明涉及一种包括平衡牵伸系统的燃烧装置，包括用于将燃烧空气输送到燃烧器部分（7）的强制通风机（6）和用于从燃烧器部分（7）中提取废气的引风机（9）。驱动机构（10）操作风扇。为了提高设备的效率并简化对其的气流的控制，根据本发明，风扇（6,9）可操作地联接，使得两者的调节是同时的，从而保持它们的输出之间的可预定的关系。这使得系统特性几乎完全匹配。驱动机构（10）与各个风扇的联接可以通过常规方式进行，但是风扇控制优选地通过速度变化实现，使用变频器系统的电动机。

摘要： The invention relates to air preheaters for burners in which combustion air is heated prior to contact with a fuel to be burnt. Preheaters have been proposed in which the air is in heat exchange relationship with flue gases but this has given rise to a condensation problem when the temperature difference between the cold air and the hot flue gases causes precipitation of harmful fluids. According to the present invention, this problem is substantially avoided by heating the combustion air in two stages. Airto be heated is passed along a path having two portions (12,16,24,22). Air in the second portion (16, 22) is in heat exchange relation with flue gases in an outer casing (2, 20), and air in the first portion (12, 24) ist in heat exchange relation with air in the second portion (16,22). By this means, direct heat exchange between the flue gases and cold air is avoided. The respective portions (12,16, 24, 22) of the air flow path are normally one within the other, enabling the conduit defining the inner portion (12, 24) to be removed without interfering with the flue gas ducting (2, 20).
