在取料流程及分料流程中,卸料小車需進行配倉操作以將燃煤卸入主廠房筒倉,在停止流程時,碼頭至堆場段皮帶機上物料需送往堆場(詳見分料流程),堆場至筒倉段皮帶機物料送入筒倉;
UNIT3 A-F倉、UNIT4 A-E倉由卸料小車定位在倉上配倉,UNIT4 F倉由小車直通實施配倉。正常情況下,同一時間,一臺機組只能由一臺卸料小車配倉;
正常情況下,每個機組的F倉作為備用倉(Bypass),僅當磨煤機檢修時會調整備用倉,但在程控系統中,任意倉都可以設置為備用倉,備用倉數量最少1個,最多4個。每組連續(xù)的非備用倉,定義為倉組。每個倉組包含的工作倉數量,最小為1個,最大為5個。每個倉的當前料位與HL2對應料位的體積差,定義為每個倉的剩余容積EV,每個倉組所包含工作倉的EV之和,定義為倉組EV;
同一機組中, 我們只考慮有3個備用倉的情況下是可以自動進行配倉的,當有4個備用倉的時候,這時可用倉為2個,這種情況屬于最不利工況,在這種惡劣的環(huán)境下只考慮人工手動配倉;
備用倉不允許卸煤,其剩余容積不計入EV,在卸料小車跨越備用倉及卸料小車跨機組時,應保證BC10(CV810A/CV810B)皮帶機上無煤(斗輪機停取料或流程停止,在BC10上保持足夠的無料段,需要控制室操作員與斗輪機司機通話確認或工業(yè)電視監(jiān)視等其他輔助手段,并在程序中作延時處理,見10跨倉程序);
程控運行中,若處于余煤平倉程序中,此時配倉可以不按預置順序,由程序判斷需向哪個倉移動;
流程啟動時,卸料小車立即向啟動目標倉移動,移動到位后對當前倉作EV、HL2、HHL判斷,之后每一次正常程序下移倉,移倉到位后均作EV、HL2、HHL判斷;但若卸料小車處于余煤平倉程序中,移倉到位后只作HL2、HHL判斷。

During the reclaiming process and distributing process, the unloading trolley shall carry out bunkering operation to discharge bunker coal into the main workshop silo. When the processes stop, the material on belt conveyor between wharf and stockyard should be transported to stockyard (see distributing process for details) and the material on belt conveyor between stockyard and silo should be transported to silo;
The bunkering of UNIT3 A-F bunker, UNIT4 A-E bunker shall be finished by unloading trolleys located on them and the bunkering of UNIT4 F bunker shall be finished by unloading trolley directly. Usually, the bunkering of one unit should be done by only one trolley at the same time;
In normal circumstances, the F bunker of every unit is taken as standby bunker (Bypass). The standby bunker will not be adjusted but for coal mill overhauling. However, any bunker may be set as standby bunker in program-controlled system. There should be 1-4 standby bunkers. Each consecutive non-standby-bunker group is defined as a bunker group and there should be 1-5 working bunkers in every bunker group. Every bunker’s excess volume (EV) is defined as the volume difference between the bunker’s current material level and HL corresponding material level. The bunker group EV is defined as the total sum of every bunker’s excess volume (EV) of the group;
For one unit, we only consider the automatic bunkering is possible for 3 standby bunkers. As for 4 standby bunkers, there would be only 2 usable bunkers. This is the most unfavorable condition. In this harsh environment, only manual bunkering should be considered;
No coal unloading for standby bunkers and their excess volumes are not included in EV. When unloading trolley across standby bunkers or units, it should be ensured that there is no coal on BC10 (CV810A/CV810B) belt conveyor (when bucket wheel reclaimer stops reclaiming or process stops, left adequate no material section on BC10. This needs to be confirmed by communication between control room operators and bucket wheel reclaimer driver or by industrial television monitoring and other auxiliary tools, and make delayed time processing in the program, see 10 across bunker program);
During program-controlled operation, the bunkering may not in the preset order in residual coal distributing program and the program determines which bunker to go;
As the process starts, unloading trolley moves immediately to the started target bunker, make EV, HL2, HHL judge to the current bunker after moving in place. Hereafter, in bunker shifting in every normal procedure, always make EV, HL2, HHL judge after moving in place; however, for unloading trolley in residual coal distributing program, only make HL2, HHL judge after moving in place. |
