Biomass compound coal for tobacco flue-curing and preparation method thereof

Abstract

The invention discloses biomass compound coal for tobacco flue-curing, which is especially suitable for combustion requirements of bulk curing barn curing equipment. The invention also discloses a preparation method thereof. The invention adopts the following technical scheme to realize the aims: the biomass compound coal for tobacco flue-curing is prepared by the following components by weight percent: 57-95% of coal slime, 0-19% of soft coal with high heat productivity, 0-19% of anthracite, 2-3% of smashed plant straw and 2-2.5% of adhesive, wherein the compound coal also comprises a sulphur fixing agent; and the preparation method has the steps of weighting and mixing the components, and evenly pressing to obtain the product. Based on the scheme, the biomass compound coal for tobacco flue-curing can be obtained, which is especially suitable for combustion requirements of bulk curing barn curing equipment.

Description

technical field

[0001] The invention belongs to a biomass briquette used for baking tobacco leaves and a preparation method thereof. Background technique

[0002] Biomass energy is an ideal renewable energy source, it has a wide range of sources, the sulfur content in biomass is extremely low, and there is basically no sulfide emission; some areas in my country have used biomass energy to provide high-quality cooking for households. , heating gas, but the application research in tobacco leaf curing is in its infancy. The annual planting area of ​​flue-cured tobacco in my country is about 15 million mu, and the annual coal consumption for curing tobacco leaves is more than 4 million tons. Since 2004, the price of coal in my country has continued to rise, resulting in rising costs of flue-cured tobacco. With the popularization and application of dense curing rooms in various smoking areas in my country, the labor intensity and energy consumption of baking have been greatly imp...
