硅碳棒根据使用的环境以及所做工作去计算它的使用功率，大家知道热量与功率之间的关系吗，下面来看下。
等直径硅碳棒热量、功率基本关系 W(瓦)=J/S（焦耳/秒） 1 kw=1 kj/s=3600 kj/h 1千卡=1大卡=1000卡(cal)=1000卡路里=4184j=4.184kj 二、水蒸气换算 利用软件，状态参数填好压力、温度两个参数，查询方式选择已知P和T，点击确定，可以获得该参数蒸汽的焓值。以9.81 540℃为例，查询焓值为3477kj/kg 1t/h蒸汽热量=1000kg/h蒸汽热量=1000kg/h*3477 kj/kg=3477*103kj/h=3477*103 kj/h÷3600（kj/h）/kw=965.8kw 但是对于热水锅炉，有常用的系数。即1MW=1.4t/h（或者1t=0.7MW） 算法（来源于网络，供参考）： 对于蒸汽锅炉，吨位为1t/h的蒸汽锅炉，是指每小时蒸汽的额定蒸发量为1吨，当与热水锅炉相对应的时候，一般又是指的低压锅炉且产生的是饱和蒸汽的，低压锅炉的额定工作压力一般为1.25MPa(表压)，而锅炉的给水温度为20℃，因此对于蒸汽锅炉，当1吨的水经过吸热后，变成1吨的饱和蒸汽(1.25MPa)时，所需吸收的热量计算方式： 饱和蒸汽(1.25MPa)的焓值：2787.7kj/kg (饱和蒸汽焓值查询). 20℃给水焓值约为：20×4.186=83.7kj/kg 1kg水变成1kg蒸汽需要吸收的热量：2787.7-83.7=2704kj/kg 所以，1吨20℃的水变成1吨1.25MPa下的饱和蒸汽所需要吸收的热量：2704000kj=2704MJ=2704÷3600≈0.7MW
