Study on Series Design of Energy-Saving Flue Cured Tobacco-Room

The method of series design, the criteria for the selection of excellent construction and the appraisal index system of the energy saving flue cured tobacco room were introduced and comparing tests of the selected constructions were conducted. Test results showed that all the 3 series of room design were adaptable to Chinese conditions. Their thermo-efficiency was about 30% higher than that of the old ones. The heat exchanger could have a service life of 5 years without repair, Tobacco quality could be raised by 0. 5 to 1 grade. The curing room was easy to operate and could be accommodated to the burning of molded coal, loose coal or even timble. There will be a bright prospect for the series curing room with evident yearly savings of coal and increase of farmer' s income.
