Positioning, quantitative (isobaric) air conditioning grate - to solve the uneven distribution of grates - submitting combustion efficiency and saving coal

Positioning, quantitative (isobaric) air regulation technology is a newly developed air conditioning technology in Yongning machinery plant in Wafangdian City, mainly used in large and medium-sized grates.

The original boiler arrangement wind device is located on both sides of the grate, and the wind from both sides of the grate enters the air chamber under the grate through the wind regulating device, and then passes up the grate surface. The wind sent through the air supply channel is uniformly and uniformly on the grate surface, otherwise it will cause uneven combustion of coal on the top of the grate, and some can not fully burn. The uniformity of the original stove grate is poor, and the uniformity of transverse air distribution on the grate surface and the sensitivity of the wind regulation are very unsatisfactory.

The positioning quantitative (isobaric) wind regulating technology provides a simple structure, flexible air conditioning, and ensures the full and uniform combustion of coal burning on the grate, and has good energy saving effect. It overcomes the shortage of existing technology.

There are several separators in the main air chamber (each partition is vertically placed along the grate) in the main air chamber, and the partition board separates the main air chamber into multiple sections to form an independent wind chamber, and each section of the independent wind chamber and the auxiliary air chamber pass through the air vent on the horizontal vertical plate. The wind holes become smaller from outside to inside, and there are data bases. The size of holes is derived from experiments and actual situations. Each independent wind room can adjust the air supply from the auxiliary air chamber to the main air chamber separately, according to the different position of the grate surface and the air supply according to the demand, that is, the positioning and quantitative wind transfer (i. e., isobaric air supply) can be realized, which ensures that the coal burning on the top of the grate is fully burned, and a large amount of coal is saved, the overall structure is simple and the action is flexible and reliable. This technology has achieved good results in practical application.
