一种锅炉烟气余热回收装置
本专利技术涉及一种余热回收装置,特别是涉及一种锅炉烟气余热回收装置。
技术介绍
锅炉是一种能量转换设备,向锅炉输入的能量有燃料中的化学能、电能,锅炉输出具有一定热能的蒸汽、高温水或有机热载体。锅的原义指在火上加热的盛水容器,炉指燃烧燃料的场所,锅炉包括锅和炉两大部分。锅炉中产生的热水或蒸汽可直接为工业生产和人民生活提供所需热能,也可通过蒸汽动力装置转换为机械能,或再通过发电机将机械能转换为电能。提供热水的锅炉称为热水锅炉,主要用于生活,工业生产中也有少量应用。产生蒸汽的锅炉称为蒸汽锅炉,常简称为锅炉,多用于火电站、船舶、机车和工矿企业。余热是指能利用而未被利用的热能。由于我国工业装备落后,能源利用率低。如化工、石油化工、建材、轻纺、冶金、动力、食品、造纸、电子电器等行业,在生产中有大量的热能直接排空,既浪费能源又污染环境。余热回收就是将浪费的热能回收利用,提高能源利用率,降低生产成本,保护环境。近十年来,由于能源紧张,随着节能工作进一步开展。各种新型,节能先进炉型日趋完善,且采用新型耐火纤维等优质保温材料后使得炉窑散热损失明显下降。采用先 ...
