vibration in boiler when bagasse moisture increases

Opportunities for improving the performance and

SRI has been investigating options for upgrading the performance of bagasse-fired boilers for several years. Dixon and Plaza (1995b) used the CFD code FURNACE to predict the effect of excess air, bagasse moisture, fuel firing rate and grate air flow distribution on the heat fluxes, gas temperatures and unburnt fuel levels in a bagasse-fired boiler.

bagasse dryer : Bagasse, the sugar cane residue after juice extraction, contains a gross calorific value of around 2270Kcal/kg. Normally bagasse is fed to boiler directly in sugar mill, the surplus is also used for in the production of paper making, animal feed, artificial board, bio-fuel ethanol, etc.

Boiler Pressure - an overview | ScienceDirect Topics

Increasing the boiler pressure and keeping the superheated temperature constant reduces the process heating available. Conversely, turbine work increases. An increase from 10 to 50 bar for maximum pressure, results in an increase from 5.088 to 8.439 MW of turbine work. This is an increase of 40%.

An effective bunker system for the storage of bagasse, which will store bagasse for the requirement of about 10 to 15 minutes for the boiler MCR, has been successfully tired and implemented. This system operates well for a bagasse that is well prepared and with 50% moisture.

Effect of Bagasse Moisture on Boiler Performance | Panchal

Abstract. As bagasse moisture content increases, greater combustion is obtained.Thus, thebagasse moisture content is an important parameter to control combustion in boilers. Simulated bagassewas used to monitor the effects of moisture content on gross calorific value (GCV) and net calorific value (NCV) and equilibrium analysis.

As is the case during startup, combined oil and bagasse firing will increase SO2 and NOx emissions. Auxiliary fuel is used whenever additional heat input is required. If the supply of bagasse to the boiler is interrupted, auxiliary fuel will be used to provide up to 100 percent of the heat input of the boiler.
