The utility model discloses a secondary heat exchanger for flue gas of a fuel heater, which mainly comprises the lower seat of the heat exchange tube at the outlet, the upper seat of the heat exchange tube at the outlet and the upper seat of the heat exchange tube at the outlet. The heat exchange tube at the outlet is arranged between the upper seat of the heat exchange tube at the outlet and the lower seat of the heat exchange tube at the outlet. Compared with the existing technology, the utility model designs and installs a flue gas secondary heat exchanger at the smoke outlet of the heater. Its advantages are mainly manifested in the simple structure, ingenuity and rationality of the flue gas secondary heat exchanger, the small resistance of flue gas flowing in the heat exchanger, the small resistance of air flowing through the secondary heat exchanger, and the high heat exchange efficiency of the flue gas secondary heat exchanger, which fully recycles and utilizes the surplus of the flue gas. Heat has the advantages of energy saving and environmental protection.
【技术实现步骤摘要】
一种燃油暖风机烟气二次换热器
本技术涉及暖风机领域,尤其涉及一种燃油暖风机烟气二次换热器。
技术介绍
燃油暖风机主要与帐篷配套使用,解决高寒地区的供暖问题,以提供良好的办公、居住环境。亦可用于北方冬季野营时帐篷内供暖,在大型固定营房和民用住房内也可使用。燃油暖风机具有强度好、可靠性高、寿命长、热效率高、可清洗、耐腐蚀、耐低温、低噪音等优点。热效率是燃油暖风机的主要性能指标,供暖时由于出风温度不宜太低,一般都应在70℃以上,受燃油暖风机外形尺寸的限制,燃烧换热器的换热面积较小,造成燃烧换热器出口烟气温度较高,一般在250℃~290℃之间,部分热量随着烟气而排放到大气中,造成能源浪费,因此需要加以改进,使得烟气中的热量能够被二次利用。
技术实现思路
基于以上所述,本申请提供一种燃油暖风机烟气二次换热器,以解决现有燃油暖风机中出烟温度过高,造成能源浪费的问题。为达此目的,本技术采用以下技术方案:一种燃油暖风机烟气二次换热器,包括出烟口换热管下座、出烟口换热管和出烟口换热管上座,所述出烟口换热管设置在出烟口换热管上座和出烟口换热管下座之间。作为本技术的一种优选方式,所述出烟口换热 ...
