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
