Problems solved by technology

Since the cross-sectional size of the air inlet is smaller than the cross-sectional size of the air chamber, eddy currents are generated at the air inlet and the local wind speed is too high, forming an "end effect". The wind pressure on both sides of the row drops significantly, resulting in uneven air supply, which affects the combustion effect of the fuel, reduces the heat conversion efficiency of the fuel, and wastes energy

Embodiment Construction

[0009] The specific implementation manner of the present invention will be described below with reference to the accompanying drawings. like figure 1 Shown: a fire grate with double air chambers with middle air outlet type air distribution chamber for uniform air distribution, with a plurality of main air chambers 1 arranged in the longitudinal direction, and between two adjacent main air chambers 1 there are partitions 2 The auxiliary air chamber 4 formed by , 3 is respectively provided with an air inlet 6 on the opposite side wallboards 5 of the auxiliary air chamber 4, and is respectively provided with an air guide port 7 on the partition plate 2 or partition plate 3, and the air guide port 7 Space is arranged between wallboard 5.

[0010] When air supply is required, the air supply fan sends the air from the two air inlets 5 into the auxiliary air chamber 4, and then enters the main air chamber 1 through the air guide port 6. The air supply is uniform, which can significa...

Abstract

The invention discloses a grate which has dual wind boxes, leads the wind to go out of the middle part and divides the wind boxes to uniformly distribute the wind. The grate is provided with a plurality of main wind boxes (1) which are arranged in longitudinal direction; and an auxiliary wind box (4) formed by clapboard (2) and clapboard (3) is arranged between the two adjacent main wind boxes (1). The grate is characterized in that the wall plate (5) of two relative sides of the auxiliary wind box (4) is respectively provided with an air inlet (6); and the clapboard (2) or the clapboard (3) is respectively provided with a wind guide hole (7). By complying with the dynamic-static pressure conversion principle, an end effect of the prior art can be eliminated, the problem that the wind pressure at two sides of the existing grate is insufficient is overcome to lead the wind supply to be uniform, and the combustion effect can be obviously improved and the energy resource can be saved.

Description

Technical field: [0001] The invention relates to a fire grate for air supply in separate chambers, in particular to a fire grate with uniform air supply, which can obviously improve the combustion effect, increase the heat conversion efficiency of fuel, and save energy. grate. Background technique: [0002] At present, the air supply structure of the compartment air supply grate is that there are multiple main air chambers arranged longitudinally, and there is a closed auxiliary air chamber formed by a partition between two adjacent main air chambers. wall panels at both ends of the chamber. Since the cross-sectional size of the air inlet is smaller than the cross-sectional size of the air chamber, eddy currents are generated at the air inlet and the local wind speed is too high, forming an "end effect". The wind pressure on both sides of the row drops significantly, resulting in uneven air supply, which affects the combustion effect of the fuel, reduces the heat conversio...
