“…Table 5 lists the lignin, cellulose, and hemicellulose contents of different biomass fuels. The morphological characteristics of harvested tobacco stalks with abundant holocellulose and alpha-cellulose are similar to those of non-woods and hardwoods [29,30], making them a better raw material for the production of biomass fuels [20,31]. The statistics state that a three-hectare field of tobacco stalks could cure one hectare of tobacco leaves.…”

“…The heat exchanger, which consists of several flue pipes, dissipates the heat generated by the burning of the fuel and is directly connected to the furnace. Typically, a conventional flue pipe layout is parallel to the ground [19,20], to produce an upward flow of hot air. This layout is not, however, conducive to heat dissipation given the length of time that the hot gas is present in the flue pipes.…”

A new system for providing heat for the flue-curing of tobacco was developed by modifying the conventional direct combustion of biomass fuel (bio-fuel) such that the energy stored in the fuels was fully utilized. The system consisted of an integrated furnace with a heat dissipation structure for combusting and gasifying bio-fuel including solid fuel as well as combusting the generated gas, and a heat exchanger with a special flue pipe layout. The new device was tested through experiments in different tobacco-growing areas, using the controlled direct combustion of coal and biomass fuel for flue-curing in a bulk curing barn. The results showed that the distribution of temperature in the longitudinal section of the new system exhibited a regular temperature transition pattern corresponding to the solid fuel and gas combustion areas. The amount of carbon monoxide in the flue gas at the chimney exit indicated that the burning of the biomass briquette fuel was more complete, with less than 1.7% carbon monoxide generated. The thermal efficiencies of the biomass briquette fuel and firewood were 55.26 and 53.17%, respectively, which were higher than that of coal (49.52%). The newly developed integrated furnace would be well suited for tobacco curing in tobacco-growing areas, and could be used commercially for drying agricultural products on different scales.

“…When DBT in the experimental barn was at 38, 48 and 68 °C, and the fuel burned steadily, referring to the literature [23], the concentration of flue gas discharged from the chimneys was measured at the central position of the chimney outlet using the automatic gas tester (TW-3200, Tuowei Qingdao China).…”

Applying biomass energy for curing flue-cured/Virginia tobacco heating is the best way to realize green tobacco production. Aiming to satisfy the heating demand for flue-cured tobacco curing, a new heating device that uses biomass briquettes as fuel for curing tobacco is adopted the first time, which was developed using modern mature electromechanical and computer technology. The new device consists of automatic feeding, ash cleaning, ventilation, and ignition systems governed by an intelligent tobacco-curing controller designed for specific curing characteristics. The results of experiments conducted with an original direct combustion coal furnace, bulk curing barn, and controlled coal-fired heating indicated that the heat supply of the new device could satisfy the heat demand during the tobacco curing process, with a good performance-controlling difference of ± 0.5 °C between the actual and target dry-bulb temperature in the barn. With its unattended heating management and use of fully burning fuel, the new device sharply decreased the cost of manual operation and tobacco leaves required per kilogram compared to a coal furnace. Considering the shape of its structure, the new device could be used to heat homes or small-scale boilers if the chip procedure of the controller is altered.

“…With energy efficiency below 30%, approximately 14 kg of firewood was consumed to obtain 1 kg of cured tobacco using direct-fired combustion suggested by Siddiqui and Rajabu [32], and then decreased to around 4.5 kg kg -1 of tobacco by Musoni et al [33]. As compared to firewood and the same direct-fired combustion mode, BBF burned more stably mainly due to its uniform size; the upgraded energy efficiency for burning BBF ranged from 39 to 42% [34]. With burning gasification gas applying the special furnace structure for BBF via manual operation [26,35], the energy efficiency could be improved from 53.17 to 55.26%.…”

In recent years, excessive carbon dioxide (CO 2) emissions have already led to a series of environmental problems. As the largest flue-cured/Virginia tobacco (Nicotiana tobacum L.) producer in the world, China currently grows about one-third of the world's tobacco annually [1], and tobacco curing (TC) is the most energy-intensive phase of tobacco production [2]. Traditionally, coal is used to directly burn and heat fluecured tobacco in a bulk curing barn [3, 4]. During the annual TC season, millions of tons of CO 2 and fly dust are emitted into the atmosphere from the chimneys, which causes serious environmental pollution [5, 6];
