The utility model discloses a coal storage yard, in which a coal conveying passage is arranged underground along the length direction of the rectangular coal storage yard, a belt conveyor is fixed in the coal conveying passage, several underground coal hoppers are arranged above the belt conveyor, and an elevated belt conveyor is fixed in the rectangular coal storage yard, on which a material unloading device is installed. The utility model has the advantages of: the coal storage yard adopts the arrangement mode of stacking coal with elevated belt conveyor and coal on underground coal bucket, which has the advantages of low investment cost, small occupation area, simple and convenient operation, safety and stability. Compared with the conventional bucket wheel stacker-reclaimer strip coal yard, the stacking height is high and the same total coal storage area is small; compared with the circular coal yard, the investment cost is low, the construction difficulty is small, the equipment installation requirement is not high, the construction period is short, the spontaneous combustion coal treatment is convenient, and the vehicle can unload coal; there is no large-scale stacking equipment in the coal yard, the maintenance workload is small, the stacking and reclaiming operation is feasible. At the same time, the auxiliary machinery operation rate is the lowest.

一种储煤场
:本技术涉及一种储料场,尤其涉及一种储煤场。
技术介绍
:储煤场作为保证燃煤火力发电厂正常稳定运行的重要设施之一,其设计方案的合理性、经济性以及运行的安全可靠性十分重要。由于国内煤炭行业的市场化,导致大部分燃煤电厂燃料来源不够稳定,这就要求电厂厂内的储煤场运行可靠、储量合适,为保证足够的储煤量,储煤场通常占地面积较大,建设投资较高。目前,国内大型燃煤电厂储煤场主要有斗轮堆取料机条形煤场和圆形煤场。斗轮堆取料机条形煤场存在的问题是单位面积储煤量小,占地面积较大,场地利用率较低;相比较而言,圆形煤场单位面积储煤量大,占地面积小,场地利用率高,但其投资费用较高,施工难度较大,设备安装要求高,施工周期较长,自燃煤处理难,且无法接卸汽车来煤。针对斗轮堆取料机条形煤场和圆形煤场存在的上述问题,结合电厂的实际情况,在电厂建设场地受限的情况下,如何设计一座占地面积相对较小,建设投资费用相对较低的储煤场方案是急需解决的技术问题。
技术实现思路
:本技术的目的在于提供一种占地面积相对较小,建设投资费用相对较低的储煤场。本技术由如下技术方案实施:一种储煤场,其包括矩形储煤场,所述矩 ...
