为提高和改善锅炉热效率,可利用锅炉排烟余热,改善燃料的干燥、着火和燃烧过程,以提高锅炉热效率。可利用热管这种高效传热元件回收锅炉排烟余热的技术,设计一种烟气排放和炉膛进风系统。该系统在工作状态下,可以把冷空气预热成一定温度的热空气,再送入炉内,加速了燃料的干燥、着火和燃烧的过程;同时强化辐射的热交换,保持稳定燃烧,并因此降低化学不完全燃烧损失和排烟损失,提高了锅炉的热效率。
In order to improve and improve the thermal efficiency of the boiler, waste heat from the exhaust of the boiler can be used to improve the drying, ignition and combustion processes of the fuel so as to improve the thermal efficiency of the boiler. Heat pipe can be used this efficient heat transfer components of boiler exhaust heat recovery technology, the design of a flue gas discharge and the furnace inlet system. Under the working condition, the system can preheat the cold air into a hot air of a certain temperature and then send it into the furnace to accelerate the process of drying, burning and burning of the fuel; at the same time, the radiation heat exchange is intensified to maintain stable combustion and therefore Reduce chemical incomplete combustion loss and smoke loss, improve the thermal efficiency of the boiler.
