The invention discloses a three-section and six-step type dense tobacco curing room coal energy-saving curing method. The method comprises the following steps of A, analyzing main coal caloric values of a tobacco curing area, calculating the main coal consumption amount of the tobacco curing area according to the heat required by each phase of the three-section and six-step type tobacco curing process, and establishing a database; B, charging coal in each phase of the curing process according to the measuring amount, and configuring the coal; using the coal with lower caloric value in the yellowing period, and using the coal with higher caloric value in the stem drying period and color fixing period with higher fire requirement. The method has the advantages that the coal is configured according to the coal consumption amount of each phase of the three-section and six-step type tobacco curing process, the fine and crushed coal is charged under the conditions of temperature rise and larger instantaneous fire, the sufficient combustion is well realized, and the combustion intensity is improved; in the temperature stabilizing and later phases, the large coal is charged into a furnace hearth, so the stability and durability in the combustion process are guaranteed; in the temperature stabilizing phase, the coal slag produced in the combustion process is combusted again, so the heat energy is sufficiently utilized, and the combustion efficiency and utilization rate of the coal are improved.
