Main topics

Drying of bagasse feedstocks

Experiences with low temperature dryers in the cane sugar industry
by Stefan Szymkiewicz & Thomas Kimmenauer

Low temperature dryers are well known for quite a few different drying applications i.e. pressed pulp in the beet sugar industry. During the last years, low temperature dryers have been introduced in China and Thailand on technical scale for bagasse drying. First experiences with such applications for the utilization of process waste heat are described.

Low temperature bagasse dryer applications for fuel saving and power export
by Saiedeh Wicht & Boris Morgenroth

Low temperature dryers offer the potential to utilize waste heat from the process to dry bagasse. This technology is well introduced in the beet sugar and other industries for many decades and has recently also been applied for the cane sugar industry at technical scale. Typically, boiler flue gas, hot water or steam, which otherwise is sent to the condenser are potential heat sources for the dryer. Depending on the availability of waste heat, the bagasse can be dried from ~ 50 % moisture to 35 – 40 % moisture, which fits well to the operation of most conventional bagasse boilers. The increase of calorific value of the bagasse allows producing additional steam, which in return can be utilized either for saving external fuel or improving the power export potential of the factory. Results of different application scenarios are described.


An overview of the role of sugar milling for decarbonisation
by Marguerite Renouf

This presentation aims to give an overarching perspective of the role of sugar milling for decarbonising the cane sugar industry. It will compile findings from previous environmental life-cycle assessment (LCA) studies that have quantified the GHG emission reduction potential from various sugar industry initiatives. The intent will be to show the extent to which sugar mills can contribute to decarbonisation of sugarcane systems, relative to other opportunities across the industry. In particular, it will emphasise the value of initiatives that free up surplus bagasse for the production of bioenergy and bioproducts that displace fossil-fuel combustion.

Contribution potential of the cane sugar industry for decarbonization
by Boris Morgenroth & Stefan Jahnke

The cane sugar industry remains not unaffected by the requirement of decarbonisation in order to counter global warming. While bagasse is basically a “green fuel” for cane sugar factories not causing additional carbon emissions, it is possible to maximise the power export from cane sugar factories what is a direct contribution versus global warming. Maximising the power export requires not only very steam efficient processes but also the application of new technologies like vapour re-compression, heat pumps and efficient bagasse dryer technologies along with boilers which allow to burn dried bagasse. Process schemes allowing to maximise the power export to the national grid are discussed.


Energy management

The predicted effects of swirl spreader combustion system retrofits on bagasse boiler efficiency

by Floren Plaza and A.P. Mann

The retrofitting, commissioning and performance of the relatively new swirl spreader combustion system (~18 years old) into existing boilers has been previously described in several papers.  In particular, it was noted that the swirl spreaders enabled the boiler to achieve high steam throughput with relatively high bagasse moisture content, and little bagasse deposition on the grate.  However, a definite comparison of the efficiency of the boilers was difficult to carry out since other modifications were carried out to the boilers at the same time.  More recently, computational fluid dynamics modelling was carried out to understand the variation in performance of a furnace where conventional spreaders were replaced with swirl spreaders, with a prediction that, for the same fuel and air input rates and temperatures, and a typical furnace with tubes covering most of the walls, a significant increase in heat transfer was predicted to occur in the furnace.  An extension of that work is reported here where the likely overall boiler efficiency improvements are predicted for retrofitting boilers with differing boiler efficiencies.  Some aspects of the effects on the boilers are discussed.
