When boiler small negative charge moves

The stand or fall of combustion operating mode, be compounded the effect of wind operating mode not only, and also withLow nitrogen burnerbear is concerned.

To assure proper blaze center place, prevent flare-up deflective, should make investment moves commonly individuallyBurnerbear allocates even, semmetry as far as possible, be about to the wind force of each burner is adjusted with quantity giving pink consistent. But be in actual in, the quantity giving pink of each nozzle is accomplished impossibly identical. In addition, as a result of structure, installation, make reach those who decorate means is different, the character of each burner is impossible also identical. The burner may not that gets used to high load capacity gets used to small negative charge; The adaptability that each burner plants to coal reachs lukewarm to steam, blaze to distributing, knot broken bits the influence that wait is different also.

On the run mode of the machine that grind coal, a, B, C, D is ground grind coal machine for brunt, e, F grinds coal machine to serve as commonly reserve grind, the meeting when also some of power plant is designed grinds A as reserve grind. Add bear to need to start reserve when the machine that grind coal, should inspect boiler to whole runs a condition and be decided. System of milling of the superstratum that start, can rise advocate, reheat vapor is warm, but smoke evacuation temperature increases subsequently, mechanical not complete combustion heats up a loss to increase; System of milling of starting A layer, combustion stability is good, smoke evacuation temperature and mechanical not complete combustion heat up a loss to reduce, water-cooling wall absorption of heat is strengthened, boiler advocate, reheat vapor is warm drop. High load capacity moves in lukewarm phenomenon of occurrence steam of tall steam depress can blow grey, rearrange to run superstratum milling system through flue, adjust every rotate speed of engine giving coal and auxiliary wind fender leave degree be able to solve.

When high load capacity, because thermic load of the chamber of a stove or furnace is high, catch fire and burn to all compare stability, its are main the problem is steam Wen Gao, easy knot broken bits. Because this moves in high load capacity in should notice to maintain steam lukewarm stability, at the same time do one's best avoids knot broken bits. Boiler moves in small negative charge when, thermic load of the chamber of a stove or furnace is low, light put out a fire. Because this should notice to maintain flaming stability and lukewarm to steam influence above all, just consider economic norms next. To prevent put out a fire, can reduce negative pressure of the chamber of a stove or furnace to be worth appropriately, close the auxiliary wind fender between small moving burner, adjust fuel capacity and wind force to want even, avoid wind speed to pass big wave motion, bad to burning nozzle strengthens surveillance to wait. Can throw oil gun to support combustion when necessary, stabilize blaze.

When boiler small negative charge moves, want to be able to be maintained only catch fire and the stability of combustion process, should reduce the machine that grind coal to run a number, maintain chroma of tall coal fines as far as possible. Of course, to increase coal fines concentration, grind wind force, boiler total wind force accordingly to should be reduced, in order to make sure right now combustion still is in relatively the wind pink of beautiful leaves the job than the relation. Such not only be helpful for the mutual ignition between blaze, facilitate adjust, get used to bear change easily; And such moving that mix to wind pink, blaze degree of filling is better also, but enkindle is stabilized quite and complete.

Decorate quadrilateral swing the combustion of gentle coal fines perfects steam of position of center of combustion of part of exchange of type dc burner, change degree is to have those who comparative to use, reason should notice to make full use of the characteristic with adjustable dip of this kind of burner. Fall in the condition that makes sure normal vapor is warm commonly, increase its to play dip angle as far as possible, in order to obtain taller combustion economy, but should notice to because temperature passes,avoid cold ash bucket tall and knot broken bits, when also should noticing burner dip adjusts at the same time quadrilateral not linkage, destroy field of motivation of the combustion inside furnace. The speed when burner of adjustment of high load capacity is obliquitous but some faster, small negative charge should put delay rate as far as possible.

Besides be forced to stay the case of carry, sometimes when boiler small negative charge moves, to maintain burner one, the rationality of 2 wind speed, need out of service a burner, out of service leaves after all in normal circumstance which burner had better, answer to consider integratedly. The circumstance allows to fall in bear, answer to maintain burner of layer of A, B, C, D to move as far as possible, set out from moving angle, consider economy and security.

Manufacturer of low nitrogen burner Energy-saving equipment reminds Yue Yang far east casting, in staying burner or the bear course that change burner, should notice its wind force and coal are measured at the same time cooperate. When the machine that grind coal overhauls breakdown to halt use, the secondary floor that creates as a result of the likelihood moves, so must reasonable arrangement run mode, lesser to the influence when high load capacity, should notice to be lighted firmly when small negative charge, answer to cast oil in time to be lighted firmly when disclosure combustion is flabby.
