Electric power generation bagasse

Power Production. Steam cycles for generation of electric power use various types of boilers, steam generators, and nuclear reactors operate at subcritical or supercritical pressures and use makeup and often also condensate water purification systems as well as chemical additives for feedwater and boiler-water treatment. These cycles are designed to maximize cycle efficiency and reliability. The fuel distribution of sources installed in the United States from 1990—1995 are as follow coal, 45% combined cycle, 27% miscellaneous, 14% nuclear, 11% solar, oil, and geothermal, 1% each and natural gas, 0.3%. The 1995 summer peak generation in the United States was 620 GW (26). The combined cycle plants are predominantly fired by natural gas. The miscellaneous sources include bagasse, black liquor from paper mills, landfill gas, and refuse (see Fuels frombiomass Fuels fromwaste). 

Brazilian sugar mills, similar to mills throughout the world, have process steam consumption of approximately 500 kg of steam per tonne of cane processed. By generating steam at 22bar/300°C, sufiicient electric and mechanical power (using back-pressure turbines) to run the plant is achieved and nearly all bagasse produced is consumed Thus, fiiel availability, and power and thermal energy requirements are balanced.
