01

Low heat value of tobacco stems The structure of the three-stage furnace, combined with the invention and innovation of key components in the circulation circuit, has changed the first stage ash circulation to two stage ash circulation, increased the number of circulation stages and formed a multi process feature. The effective combustion process in the boiler furnace is extended, which prolongs the fuel combustion time and makes the fuel combustion more sufficient; Meantime, the three-stage furnace is conducive to the arrangement of the boiler heating surface and the improvement measures in the arrangement of combustion organization and heat exchange surface have improved the thermal efficiency of the boiler. The operating thermal efficiency range of the boiler under design conditions is 88% -92%, saving customers' heat costs.

02

High tar content in tobacco stems with adhesive properties of tar By extending the effective combustion process of tobacco stem in the boiler furnace, harmful substances such as smoke and tar can be fully decomposed and burned out. It can effectively avoid slagging problems.

03

The high content of alkali metals in tobacco stems is harmful and prone to dust accumulation This technology arranges a convective heating surface downstream of the intermediate temperature separator, and the inlet flue gas temperature of the economizer is lower than the bonding and deposition temperature of the alkali metal, which can effectively prevent the accumulation of ash on the convective tube bundles.
