CFD modeling of combustion of sugarcane bagasse in an

Apr 01, 2017 · In this study, a CFD model is developed to evaluate the performance of an industrial boiler furnace running on sugarcane bagasse. The model was developed in the commercial software ANSYS FLUENT and includes user-defined functions programmed in C language defining devolatilization phenomenon as well as combustion on the grate.

9.10.1.1 Sugarcane Processing

chemicals. Bagasse and bagasse residue are primarily used as a fuel source for the boilers in the generation of process steam. Thus, bagasse is a renewable resource. Dried filtercake is used as an animal feed supplement, fertilizer, and source of sugarcane wax. Molasses is produced in two forms: inedible for humans (blackstrap) or as an edible

Sugar Cane Ethanol Plant - processdesign

Jan 17, 2014 · Produced lignin will be added to the remaining 10% of the bagasse material for combustion in the steam boilers as can be seen in the Milling/Pre-treatment PFD and the Plant Utilities PFD. These splits were based on research studies our team found on the utilization of the bagassse not only as a fuel, but also as an additional source of ethanol.

Optimizing Combustion of Bagasse Boilers

Jan 01, 2010 · Newer bagasse boiler designs take into account more automation in drying and dispersing bagasse, yielding up to 5,000 to 8,000 Btuh/lb of bagasse. Combustion of low-moisture bagasse facilitates constant boiler heat control. Bagasse is commonly dispersed onto combustion grates to maintain constant furnace temperature and water pressure.

Sugar Cane Thermal Boiler

The dry cane sugar residues is good biomass energy. Bagasse drying can use boiler flue gas drying. Sugar plant boiler flue gas temperature is usually between 160 ~ 180 ℃, still has a great value of thermal energy. The hot air will be extracted from the boiler flue and sent into the dryer by induced draft fan.

CFD simulation of sugarcane bagasse combustion in an

The simulation of an industrial boiler in CFD (Computational Fluid Dynamics) is usually done by stages due to the extensive size and the (HCV) of the bagasse. (8118498 J/kg). The two-step stoichiometry is presented in eq. (2) – (3).

US4376343A - Method and apparatus for drying bagasse

An outer cylindrical drum has an inner drum concentrically mounted therein in spaced relationship, to form coextensive outer and inner drying chambers that are connected to a common source of hot exhaust gases from a sugar factory boiler. Raw bagasse is first passed through the outer annular chamber to effect primary drying thereof, and then a portion of the primary dried bagasse is divided

bagasse or rice husk ) as fuels. Capacity of the boiler is 20 tph. Steam is expanded in an extraction and condensing turbine connected to a 3 MW alternator. Extraction steam goes to process and duly returned to boiler as condensate. 1.4 Evaporation plant As mentioned above spent wash from distillation is used as fuel in the boiler. In this

EPA Challenges for Bagasse Fired Power Stations

requirements did pose a challenge to the engineers tasked with the boiler design. Clewiston Boiler #8 . The USSC requirement was for a 500 000 lbs/h [~226 800 kg/h] boiler delivering 600 psig, 750ºF [~4137 kPa, ~399°C] steam when firing bagasse as primary fuel and capable of 60% MCR output when firing oil, as a start-up and supplemental fuel.

Bagasse fired boilers (Paper & Discussion) : Proceedings

BAGASSE FIRED BOILERS. By G. E. Gamble. "Bagasse" is the term applied to the waste fibres of sugar cane, after the sugar juices have been extracted in the mills. It consists of fibre and water, plus a certain amount of sugar juices. The amount of fibre and moisture varies considerably, being largely influenced by the nature of the soil, type of

Renewable energy generation

Sep 11, 2018 · A model of a bagasse-fired boiler at RCL Komati was developed by John Thompson using the commercial CFD software package ANSYS® Fluent. The simulation included the interaction between the particle and gas phase with basic chemistry, which suited the initial focus, namely, the heat transfer to a tube bank in the combustion zone.

Bio-oil Production from Biomass: Steps toward

Metso, UPM, Fortum, and VTT have developed the world's first integrated bio-oil production concept to provide an alternative to fossil fuels. The consortium has constructed an up to 7 tons/day bio-oil production pilot unit, which uses a bubbling fluidized-bed (BFB) pyrolysis reactor integrated with a conventional fluidized-bed boiler. Proof-of-concept has been carried out; close to 90 tons
