Detailed Description

The following describes embodiments of the present invention in further detail with reference to the accompanying drawings and examples. The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention.

As shown in fig. 1-3, the utility model provides an air recycling ventilation beam capable of reducing steam consumption heat in a power plant, which comprises a coal economizer ventilation beam 1, wherein one end of the coal economizer ventilation beam 1 is butted with a butt joint 2;

the upper surface of the butt joint 2 is provided with a first joint 3, one end of the butt joint 2, which is far away from the economizer ventilation beam 1, is provided with a second joint 4, one end of the economizer ventilation beam 1, which is far away from the butt joint 2, is provided with a guide pipe 5, the inside of the butt joint 2 is provided with a gathering mechanism, and the inside of the economizer ventilation beam 1 is provided with a blocking mechanism.
