在取料流程及分料流程中,卸料小车需进行配仓操作以将燃煤卸入主厂房筒仓,在停止流程时,码头至堆场段皮带机上物料需送往堆场(详见分料流程),堆场至筒仓段皮带机物料送入筒仓;
UNIT3 A-F仓、UNIT4 A-E仓由卸料小车定位在仓上配仓,UNIT4 F仓由小车直通实施配仓。正常情况下,同一时间,一台机组只能由一台卸料小车配仓;
正常情况下,每个机组的F仓作为备用仓(Bypass),仅当磨煤机检修时会调整备用仓,但在程控系统中,任意仓都可以设置为备用仓,备用仓数量最少1个,最多4个。每组连续的非备用仓,定义为仓组。每个仓组包含的工作仓数量,最小为1个,最大为5个。每个仓的当前料位与HL2对应料位的体积差,定义为每个仓的剩余容积EV,每个仓组所包含工作仓的EV之和,定义为仓组EV;
同一机组中, 我们只考虑有3个备用仓的情况下是可以自动进行配仓的,当有4个备用仓的时候,这时可用仓为2个,这种情况属于最不利工况,在这种恶劣的环境下只考虑人工手动配仓;
备用仓不允许卸煤,其剩余容积不计入EV,在卸料小车跨越备用仓及卸料小车跨机组时,应保证BC10(CV810A/CV810B)皮带机上无煤(斗轮机停取料或流程停止,在BC10上保持足够的无料段,需要控制室操作员与斗轮机司机通话确认或工业电视监视等其他辅助手段,并在程序中作延时处理,见10跨仓程序);
程控运行中,若处于余煤平仓程序中,此时配仓可以不按预置顺序,由程序判断需向哪个仓移动;
流程启动时,卸料小车立即向启动目标仓移动,移动到位后对当前仓作EV、HL2、HHL判断,之后每一次正常程序下移仓,移仓到位后均作EV、HL2、HHL判断;但若卸料小车处于余煤平仓程序中,移仓到位后只作HL2、HHL判断。

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.
