Coal-fired generator set and rotary air preheater thereof

一种燃煤发电机组及其回转式空气预热器

Abstract

本发明公开了一种燃煤发电机组的回转式空气预热器,包括导热转盘和沿周向依次并列设置的烟气仓、高压风仓和低压风仓,所述导热转盘连续转动能够循环依次经过所述烟气仓、所述高压风仓和所述低压风仓,所述高压风仓的出口与所述低压风仓的进口连通。在该回转式空气预热器中,其中低压风仓的中低压进风仓部从高压风仓处引入一部分加热后的高压风,不仅保证风力,而且能够避免再单独使用风机,以降低整体体积和成本。所以该回转式空气预热器能够有效地解决现有技术中回转式空气预热器中体积大、成本大的问题。本发明还公开了一种包括上述回转式空气预热器的燃煤发电机组。
The invention discloses a rotary air preheater of a coal-fired generator set. The rotary air preheater of the coal-fired generator set comprises a heat conducting rotary disk, smoke bin, high-pressure air bin and low-pressure air bin, wherein the smoke bin, the high-pressure air bin and the low-pressure air bin are sequentially arranged in the circumferential direction side by side. The heat conducting rotary disk rotates continuously and can circularly and sequentially pass through the smoke bin, the high-pressure air bin and the low-pressure air bin. An outlet of the high-pressure air bin communicates with an inlet of the low-pressure air bin. In the rotary air preheater, a low-and-medium pressure air bin in the low-pressure air bin introduces part of heated high-pressure air from the high-pressure air bin, so that the wind force is guaranteed, and additional application of a draught fan is avoided; and therefore, the overall size and cost are reduced. The rotary air preheater of the coal-fired generator set can effectively solve the problem that in the prior art, a rotary air preheater is large in size and cost. The invention further discloses the coal-fired generator set comprising the rotary air preheater.
