Moisture: Moisture content in the biomass reduces the calorific value and efficiency, increases weight during transportation and causes storage problems. The moisture in biomass fuels is usually high hence it has to be dried and made dense till the moisture content is around 7-8% which is ideal for transportation, storage and combustion. Low
than 100 Ibm/hr of steam to utility boilers in excess of 10 million Ibm/hr. The focus here will be on boilers sized in between these two extremes, which is also where there is the greatest diversity of design. In order of increasing capacity, three boiler types are the fire-tube, water-tube and waterwall boilers.
BOILER DESIGN AND SELECTION IN THE CANE SUGAR Bagasse and hogged wood have similar characteristics, fired" condition they have high moisture contents, Boiler design - Wikipedia, the free encyclopedia. Boiler design is the process of When the design specifications of a boiler are determined, design engineers can estimate a
moisture of bagasse at least 2%. As the gross calorific value of bagasse increases the requirement of bagasse i.e. fuel reduces for same output. Hence the boiler efficiency increases by 1 %. As the bagasse requirement of particular output reduced the bagasse energy can be saved, it is nothing but the energy conservation.
As moisture of bagasse is reduced efficiency of boiler increases. Other properties of fuel remain constant but by decreasing the moisture % in fuel NCV of bagasse increases which decrease losses in boiler. Efficiency has been calculated for coal having GCV3000Kcal/kg of fuel and has been compared with efficiency calculated using bagasse as fuel.
Moisture content has a significant influence on the per formance ofa bagasse fired watertube boiler. Under normal milling conditions moisture content varies between 47%and 56%. Whilst superficially this may seem a narrow band, the specific moisture content, i.e., the moisture content per unit mass of dry fibre increases rapidly in this range
Monitor with MoistTech's IR-3000 Moisture Sensor. The IR-3000 near infrared (NIR) online moisture detector and software system was designed to measure the moisture at any point in the bagasse drying process. You can avoid over drying because the sensor provides non-contact measurement, allowing moisture to be controlled in real time.
Typically a mill wet bagasse contains 50% moisture with a gross calorific value of 2270 kcal/kg (˜1900 KJ/kg). Normally bagasse is directly fed to the boiler to generate the steam and surplus bagasse is stored in bagasse yard. It is a well-known fact that calorific value of bagasse is decrease with increase in moisture of bagasse.
increase in fuel moisture will translate into increased gas volume flow, gas velocity and pressure drop over the convective surfaces of a boiler (figures 4, 5 and 6). As explained above the optimum excess air is a function of the fuel moisture, thus an increase in moisture translates into increased gas and air side velocities.
The mechanical depithing process contributes a lot of environmental disposal problem. In this mechanical process the 8-10 % pith cell removed and 20-25 % useful fiber lost due to hammering and subsequently in wet depithing or washing further generate heavy amount of wet pith with 70 -80% moisture contents, which create heavy disposal problem.
A problem associated with dust collectors for bagasse fired boilers is the predominance of smaller particles inthe gas to be cleaned (Allan, 1981). This increases the difficulty of removing the necessary proportion of particles. Alternative collector types The types of dust collectors which could be used on sugar mill boilers are:
There is a great contrast of boiler efficiency when used dry or wet bagasse (50% moisture), resulted as 52% and 84% respectively. The evaporation coefficient of wet bagasse is inversely proportional to bagasse moisture contains.
Steam lost time will be minimised as bagasse boilers will maintain steam pressure much better because of improved boiler efficiency. Reducing Final Bagasse Moisture down to 45.5% is the most effective option for spending a small sum with fantastic ROI.
In 2010, the Brazilian Energy Matrix presented 47.6% of renewable source, a similar participation from the last six years and one of the majors increases since 1992, with the sugarcane bagasse presenting a participation of 19.3%; energy from hydro-power of 13.7%; and 14.6% of firewood, charcoal and other renewable sources ().World average for renewable generation was around 15.6%.
Energy balance of the boiler requires that heat input is used to (1) evaporate feed water, and increase its temperature to T. s, (2) increase the temperature of flue gases to T. g, (3) increase the temperature of the vapor resulting from the evaporation of bagasse moisture to T. g, and (4) increase the temperature of inert ash to T. g
1.6 Wood Waste Combustion In Boilers 1.6.1 General 1-5 The burning of wood waste in boilers is mostly confined to those industries where it is available as a byproduct. It is burned both to obtain heat energy and to alleviate possible solid waste disposal problems. In boilers, wood waste is normally burned in the form of hogged wood, bark, sawdust,

A 2500 TCD sugar mill generates 750 tons of bagasse per day with 50% moisture. When the same is dried to 30% moisture, the increased calorific value even after taking into account the weight loss is 20-22%. This implies that by drying bagasse up to 30% moisture, sugar factories can save 150 tons of bagasse per day with 50% moisture,
useful contribution. This moisture restricts the efficiency of the boiler to around 70%. If this moisture is removed from the bagasse before it is fed into the boiler, the boiler size can be designed to be much smaller in dimensions for the same output or the capacity of the boiler can be increased in an already existing boiler.
