Research On The Heat Interchanger's Different Material Comparison Of Bulk Curing Barn

The bulk curing barn will soon become the mainstream curing equipment in ourcountry. In recent years, bulk curing barn were promoted rapidly. In different tobaccoproduction areas, the types of bulk curing barn, especially the heating system of thebulk cuing barn, are various. In the multitudinous heating system, the heatinterchanger nearly all is a steel pipe. However in the use process the steel pipeinoxidizability was discovered too weak, the period of revolution is short, to this kindof high investment, without doubt is one kind of huge waste. This article research onthe heat interchanger's different material: the steel pipe, the fire-proofing material andthe ceramic fire tube using bulk curing barn under this kind of background. Resultindicated that, under the certain radiating surface, using the ceramic fire tube took thebulk curing barn's heat interchanger, so long as the connection seal has finished,cannot affect the quality of tobacco leaf, meanwhile has the superiority which thesteel pipe or the fire-proofing material is unable to compare: it may reduce the costgreatly, the installment, the service and the replacement become more convenient, theperiod of revolution is longer and so on. Simultaneously aimed at the distribution andthe radiating surface of ceramic fire tube have studied, finally indicated: Under thesame conditions, the ceramic fire tube's radiating surface is about to the steel pipethen meets the needs. If oversized the difficulty of installment is enlarged,simultaneously the connection also are more, the hidden danger are more, but also tothe wind speed in the barn to have certain impediment. Although excessively smallthe installment is convenient, the wind speed of each place in the barn is bigger, theconnection are also few and the seal even more has the guarantee, but easy to exist thetemperature increment is not prompt as well as the maximum temperature cannotachieve the curing demand. Moreover in using the ceramic fire tube took the heatinterchanger of bulk curing barn, certainly must guarantee the connection's leak-proofquality is completed, can guarantee the tobacco leaf curing quality.
