Description
Technical field
The present invention relates to casting field, specifically a kind of furnace cupola fuel gas long-distance sand transport reuse means.
Background technology
Existing Some Enterprises are utilized in device in blast-heating cupola burner gas residual heat, utilize what CO gases in furnace gas burnt
Design, but actual utilizing status are not obvious.《Heilungkiang is metallurgical》In publication page 20 and page 21 of the 3rd phase in 2001, publication
Jixi sky dragon ductile iron pipe Co., Ltd, author：Wang Chunxing, written by " top formula blast-heating cupola centrifugal ductile cast tube production in
Application " as soon as in text, there is again burn discussion of the formula blast-heating cupola in top using CO in furnace gas.But the profit of burning again of this kind of CO
With there are two kinds of defects, one is the top that top formula blast-heating cupola is arranged on charge door, because CO gas densities are slightly less than air
Density, the CO gases in furnace cupola can be scattered an equal part from charge door naturally when by charge door；Two is because adding
The air of material mouth enters, and can more reduce CO gas concentrations.Under regular situation, CO gas concentrations stabilization exists at cupola charging mouthful
15-18%, such as CO gas concentrations are down to less than 12.5%, will not realize burning again.
In the prior art, there is not yet the fuel gas based on CO gases that furnace cupola is discharged in process of production（CO、
CH4、H2Deng）The report that long-distance sand transport is recycled.
In sum, in the prior art, the fuel gas based on CO gases that furnace cupola is discharged in process of production
（CO、CH4、H2Deng）Without can effectively utilize, long-distance sand transport recycling is more not carried out, is unfavorable for industry energy conservation emission reduction.
