两回程间接冷凝热水锅炉
本技术涉及一种热水生产装置,特别涉及一种燃气锅炉。
技术介绍
现有技术中,有一种一体式两回程型冷凝常压热水锅炉,其专利申请号:201220403775.X,申请日:2012-08-15,公开号:CN202902619U,公开日:2013-04-24。该装置采用卧式两回程式结构,其燃烧器输出到炉膛左端,炉膛右端连接回燃室,回燃室右端用T型接头连接底面,底面上设有弹簧式安全防爆门,回燃室向左通过对流管束连接前烟箱,前烟箱向上通过连接烟道到冷凝器,冷凝器烟气出口设在冷凝器顶部;冷凝器的钢铝复合翅片管呈顺列或错列排列,钢铝复合翅片管两端与冷凝器壳体用L形集水板焊接成水通道。该锅炉的卧式两回程式结构与冷凝器的钢铝复合翅片管结构合理设置充分利用了热能的品位、烟气余热,在一定程度上提高了锅炉效率,使得锅炉结构更加合理,导热性能更好,同时提高了锅炉寿命。其不足之处在于:该锅炉的NOx排放较高,烟气的热利用效率仍旧较低;长时间的外循环使用,使得炉水质量较差,容易结垢。
