The knot broken bits of the itself of ash content is characteristic, this is main the compositive circumstance with all sorts of compound in grey bate temperature, ash (content of sulfur, iron is big, grey dissolve point is low) , the atmosphere with located coal ash (ash is in reducing atmosphere to be nodded than oxidisability atmosphere dissolve low) wait for an element to concern.
The external cause of knot broken bits:
1, empty tolerance is not worth; when combustion
2, fuel and air mix inadequate;
3, blaze is deflective;
4, boiler excess load runs;
5, lukewarm heighten of smoke of exit of the chamber of a stove or furnace (air leak of bottom of the chamber of a stove or furnace, empty tolerance is overmuch, match wind undeserved, coal fines is too thick wait to be able to make move on blaze, exit smoke temperature rise is fast) ;
6, the chamber of a stove or furnace when boiler is designed accumulates the intensity that hold heat to be chosen too greatly. | The pyroelectricity industry technology such as power plant boiler, turbine, electric, water treatment communicates
Concrete analysis: What your factory uses is inferior soft coal, but the burner that sees you decorates means (did not use minute of grading wind) , so I feel although be inferior soft coal,you burn used coal, calorific quantity affirmation is not tall, but ash content content won't be not big (you did not show) of ash content content. So cause the consideration with serious broken bits of knot of the chamber of a stove or furnace I figure the likelihood still moves adjust the problem that go up!
The adjustment that prevents coping knot broken bits commonly the principle is: Maintain inferior wind force and wind speed, 2 wind from on to below by arrive greatly small principle matching wind, in order to control combustion rate, reduce blaze center position. This kind of my view adjusts methodological just in time with what you mention contrary;
Another if be blaze center,slant back wall and cause coping knot broken bits, wind force that that should try to move or so two side or wind speed ability is effective (the wind force that moves big where a side, depend on cut a circle to be tangent or) of a traditional method of indicating the pronunciation of a Chinese character by using two other Chinese characters, you can try to be analysed.
Bottom cold ash bucket is in knot broken bits, my analysis can have two to plant likelihood: It is wind below 2 to coal fines hold attraction in the palm if insufficient; is this reason, increase wind below 2 times appropriately, can prevent broken bits of knot of cold ash bucket so, but cannot be moved like what you say in that way, namely broken bits of knot of cold ash bucket of back wall bottom is serious, drive lower level of big back wall two 2 wind) , I feel crucial or should analyse a pattern that cut a circle first, come to those who reduce adjacent angles of back wall upper reaches to play wind speed 2 times by air current direction next, increase back wall appropriately at the same time the; of below 2 wind of a horn the rate of 2 below 2 air current that are direction of interfuse back wall are too old, cause its downstream (back wall side) one, 2 times wind efflux breaks up, position of flaming of local coal fines is inferior. Its adjust a method also should be a when reduce adjacent angles of back wall upper reaches below 2 second wind speed.
