确定锅炉出力或容量大小的核算基础

    一般山东九卅娱乐的经济负荷在额定负荷75%以上,所以经常应使在用的锅炉的实际负荷是在机组本身额定负荷50%以上,也就是说制造厂提供的设备在额定出力50%~100%间应保持稳定的高效。

    The general economic boiler load in the rated load above 75%, so often should make the actual load in the boiler is above the rated load unit itself 50%, that is to say the manufacturer's equipment at rated output 50%~100% should be stable and efficient.

    以往用户为了安全起见时有购置过多富余量情况,致使设备常期在低负荷下运行,很不经济。一般总容量在8吨/时或热功率在6兆瓦(MW)以上的锅炉房,以选用三台的设备容量较合适。由于冬、夏季的差异,可以选购不同出力的设备。

    In the past, users had to buy too much surplus for safety, which made the equipment run normally under low load, which was uneconomical. A boiler room with a total capacity of 8 tons / time or a heat power of 6 MW (MW) is selected, and the capacity of three units is more suitable. Due to the difference between winter and summer, you can choose different output equipment.

    但是对于新建锅炉房选择出力相同设备在操作、维修、管理等方面都有比较方便、经济。这样的锅炉房辅机配套布置可以合理安排。如果考虑到高、低峰和冬、夏季等差异较大情况下,也可选择二大一小的设备。

    But for the newly built boiler room, the output of the same equipment, in the operation, maintenance, management and other aspects of the more convenient and economic. The auxiliary arrangement of the boiler room can be arranged reasonably. If you take into account the high, low peak and winter, summer and so on, the difference is large, you can also choose two large and small equipment.

    一般地说应根据生产工艺上用汽量或采暖面积及生活用热水需要的供热量来确定锅炉的出力或容量。首先用户要弄清总的负荷范围;其次是高峰情况,包括高峰负荷持续时间,高峰的频率,也就是高峰出现的周期性,例如每月高峰出现次数,每周、每月以及一年内冬夏季的差异。

    Generally speaking, the output or capacity of the boiler should be determined according to the amount of steam or heating area and the amount of heat needed for living hot water. The first user to load the total range of understanding; second is the peak, including peak load duration, peak frequency, which is the peak period, such as the peak number of monthly, weekly and monthly differences within a year, winter and summer.

    摸清总的负荷需要和高峰后就可以考虑设备容量和台数选择。在选择时还要考虑事故停炉备用量问题。备用量一般来说是指一台备用锅炉。这需要根据用户本身的重要性来确定,如果生产使用上连续性要求较高必须认真考虑备用设备的问题。

    The capacity and number of units can be considered after finding the total load demand and the peak. In the selection, we must consider the problem of emergency shutdown capacity. Reserve capacity, in general, refers to an auxiliary boiler. This needs to be determined according to the importance of the user itself. If the continuity of production is high, the problem of standby equipment must be considered carefully.

    根据情况需要新建锅炉房,选择比三台更多一些设备亦可,但不宜过多,与其采用很多台的设备不如选择高一档容量的设备。在目前国内设备质量情况下,考虑备用机组是必要的。

    According to the situation need to build a new boiler room, choose more than three units, but also not too much equipment, rather than using a lot of equipment, choose a high capacity equipment. Considering the quality of domestic equipment, it is necessary to consider the standby units.
