    • There is provided a wood pellet burner assembly, indicated generally by the reference numeral (1) for a wood pellet boiler, not shown. There is a fixed and easily removable fuel apertured grate (41) mounted above and spaced apart from a base wall (22) forming part of a main support enclosure (2). A movable scraper sub-assembly (50) carrying an apertured flame tube (42) is provided which can be moved in and out of the main support enclosure (2) to perform a scraping action on the fixed fuel apertured grate (41) to deliver ash and clinker which have not fallen through the grate (41) during combustion off the grate (41) out of the main support enclosure (2). This cleaning operation can be carried out at suitable preset time intervals.

    • This invention relates to a power converter (1 ) comprising a converter input (3), a converter output, a power factor pre-regulation stage (5), an isolation stage (7) and a control unit (9). The power factor pre-regulation stage (5) further comprises a buck power factor correction (PFC) circuit (15) and a bulk capacitor (25) fed by the buck PFC circuit. The amount of line current provided to the bulk capacitor (25) by the buck PFC circuit (15) may be adjusted according to the converter requirements in order to keep the voltage across the bulk capacitor (25) sufficient to ensure uniform operation of the power converter. Monitoring of the voltage across the bulk capacitor (25) and monitoring of the isolation stage (7) output current is provided to determine when additional current is to be applied to the bulk capacitor (25) and to ensure the power converter (1 ) operates within pre-defined parameters.
    • 本发明涉及包括转换器输入(3),转换器输出,功率因数预调节级(5),隔离级(7)和控制单元(9)的功率转换器(1)。 功率因数预调节级(5)还包括由降压PFC电路馈送的降压功率因数校正(PFC)电路(15)和大容量电容器(25)。 由降压PFC电路(15)提供给大容量电容器(25)的线路电流量可以根据转换器要求进行调整,以便保持大容量电容器(25)两端的电压足以保证功率的均匀运行 转换器。 提供对大容量电容器(25)两端的电压和监视隔离级(7)输出电流的监控,以确定何时将附加电流施加到大容量电容器(25)并确保功率转换器(1)工作 在预定义的参数内。

    • The invention relates to the integrity testing of a heat exchanger (1) having a high-pressure section (2) and the low-pressure section (3). By using valves (5), (6), (11) and (12) it is possible to isolate the heat exchanger from the larger system or plant in which it is incorporated. Having isolated each section from the larger system the high-pressure section (2) is pressurised while maintaining the low-pressure section (3) at atmospheric pressure. Then after a preset time the pressure in the low-pressure section (3) is measured and if it has raised there is a leak. Similarly measuring a pressure drop in the high-pressure section (2) will provide the same result.
    • 本发明涉及具有高压部分(2)和低压部分(3)的热交换器(1)的完整性测试。 通过使用阀(5),(6),(11)和(12),可以将热交换器与其并入的较大的系统或设备隔离。 从较大的系统分离每个部分,高压部分(2)被加压,同时将低压部分(3)保持在大气压力。 然后在预设时间之后,测量低压段(3)中的压力,并且如果它已经升高,则存在泄漏。 类似地,测量高压段(2)中的压降将提供相同的结果。
