When the 2 ton steam boiler operates, the working fluid in the evaporating heating surface will have pulsation phenomenon, and its flow rate will fluctuate periodically with time. Moreover, the hydrodynamic characteristics are multi valued. In addition, the direct current steam boiler consumption of water pressure head is relatively large.
当2吨蒸汽锅炉运行工作状态下的时候，其蒸发受热面中的工质将存在脉动现象，其流量会随着时间的变化作周期性的波动;而且水动力特性呈多值性。另外，直流蒸汽锅炉消耗水泵的压头也比较大。
In the process of the steam boiler heat transfer, once through the heating surface, the second kind of heat transfer deterioration phenomenon must appear. At the same time, the direct current boiler has no drum, and the salt brought by the water supply is removed by steam, and the rest of the water is deposited on the heating surface, so the requirement of water quality is relatively high.
在蒸汽锅炉的传热过程中，是一次通过各受热面，第二类传热恶化现象一定要出现。同时，直流锅炉没有汽包，给水带来的盐分除一部分被蒸汽带走外，其余全沉积在受热面上，所以对水质的要求也是比较高的。
The heat storage capacity of a steam boiler is not large, so when there is a disturbance, there will be a lack of self compensation capability and a large change in the parameter speed. When the DC steam boiler load change, we must also adjust the amount of water supply and the amount of coal to keep the material balance and energy balance, in order to stabilize the steam pressure and steam temperature.
蒸汽锅炉的储热能力不大，因此当其发生扰动的时候，会存在自补偿能力不足及参数速度变化大的现象。当直流蒸汽锅炉的负荷发生变化时，必须要同时调节给水量和燃煤量，以保持物质平衡和能量平衡，才能稳住汽压和汽温。
In order to reduce the heat loss and the work loss of the direct current steam boiler, a bypass system should be installed as soon as possible. Since the steam boiler has no steam drum, the heating process can be faster, so it will start faster.
启动过程中，为了能够减少直流蒸汽锅炉热量损失和工质损失，尽量要加装一个旁路系统。由于直流蒸汽锅炉没有汽包，升温过程可以快一些，所以它的启动速度会比较快。
