The present invention discloses a new type of energy-saving furnace for combined heating furnace of continuous reforming device. Reforming the heating furnace, the pre hydrogenation material reforming the original single heating and boiling material, together with the reforming of four in one furnace convection chamber combined to form a complete radiation heating system; heating the room complete heating system 4 kinds of reaction feeding, used for heating device other materials such as feed, hydrogenation reboiler feed flow chamber of heat, so as to cancel the original production of steam convection chamber. Every material heated in the convection chamber is provided with adjustment means, such as steam preheater, etc., to make up for the deficiency of heat load and the regulation of heat load when the working condition changes. The heating equipment of the reforming heating furnace is mainly composed of a radiation chamber, a convection chamber, a high temperature air preheater, a low temperature air preheater, a steam heater, a blower, an induced draft fan and a chimney. The preheater is equipped with two stages of high and low temperature to achieve the highest air preheat temperature and minimize the fuel consumption.

连续重整装置组合式加热炉节能新炉型
本专利技术属于石油化工行业连续重整装置,特别涉及一种加热工艺及设备,能将重整装置中所有需要加热的工艺介质组合到同一台加热炉中,并能顺利实现各物料热负荷自由调节的组合式加热炉工艺及设备。
技术介绍
在石油化工行业中,连续重整装置主要用来生产高质量汽油或为下游提供优质化工原料,我国近年来在引进技术的基础上已经兴建了几十套重整装置。这些装置的反应进料加热炉大多采用联合的辐射室,即将4种反应物料的加热盘管组合在一起布置在同一个辐射室中,一般称为四合一加热炉。也有少数装置因工艺原因采用3种反应物料,炉子则为三合一加热炉。这些加热炉一般均为自然通风,不设空气预热器,燃烧器布置在侧面或底面,烟气余热由对流段产生蒸汽来回收,对流室设在辐射室顶部。为了尽量减少反应物料的压降,现有四合一加热炉中的反应进料全部只在辐射室的U形盘管中加热,而不经过对流室预热。为了回收辐射室出来的温度约为800℃的高温烟气的余热,基于引进技术的现有四合一加热炉全部都在对流室设置了蒸汽发生器,这就相当于大概有三分之一的优质燃料其实是用来发生蒸汽了。由于中国的国情是煤多油少 ...
