"过热蒸汽加热问题",

Reply #32020-05-04

"Seja bem-vindo,如果使用过热蒸汽，3.0Mpa，1 ℃，工况一：通过换热器加热热水；工况二：：直接喷射到水里加热热水，相比采用3.0Mpa、15℃左右饱和蒸汽加热有什么优缺点。",

"换热器稳定，直接加水省蒸汽",

"一种属于间壁式换热，一种属于间壁式换热。。前者有传质发生也就是有物质传递针对这种情况可能可能热利用率较高设备简单。后者就属于换热器热效率不及前者。",

"通过换热器加热热水过过热蒸汽要先消耗显热再消耗潜热。",

"本帖最后由清城君于222--5-6 99:3 �辑工况一的效果会比工况二效果差因为蒸汽的热量主要主要来自于潜热过过热蒸汽的潜热比饱和蒸汽难释放3.0Mpa（表压温度大约14℃不达到155℃间壁换热结束蒸汽冷凝水温度较高如果换热面积不够的话可以输入的蒸汽量量不足难以实现预期加热效果",

"前者虽然前期投入成本稍微大一点（换热器)但是安全高效、换热转换率高但是后者需要储罐但是是直接利用蒸汽加热水源有点危险而且换热效率不高而且浪费热源源看自身现场情况决定吧。",

"胡说八道你见过用过热蒸汽加热的吗 �蒸汽入水浪费浪费热能？你见过北方烧澡堂的吗不学知识也没见识的小小屁孩",

"为什么不使用减温减压器？",
