摘要
Abstract
Low-frequency noise of the vertical heat recovery steam generator(HRSG) of a gas power plant is found to be very large. Because of the compact layout in the plant area, the conventional whole sound insulation enclosure measures cannot be implemented. Therefore, the low-frequency noise of this type vertical HRSG is investigated. It is found that the low frequency noise mainly come from the vortex shedding when the hot smoke flows through the heat-exchange array. According to the results of analysis, a noise source control device for the vertical HRSG of the gas power plant is researched and developed and assembled inside the HRSG. As a result, the low-frequency noise of the HRSG is significantly reduced and the surrounding acoustic environment is greatly improved.关键词
