Abstrak
A high levels of air pollution that came out of the boiler caused by bagasse as fuel which has 48 – 52 % moisture that makes incomplete combustion. The high of temperature of the smoke gases that exit through chimney can still be used to drain the dregs using rotary dryer. Through the utilization of gas fumes wasted which temperature 220 to drying baggase, it can improve calorific value 39.684.000 cal/hour with capacity of production is 35 tonnage /hour, can reducing moisture of baggase till 23,6% and pollutant in environment. In order to minimize content of pollutans through chimney we use electrostatic precipitator (ESP) which catch soot and particulate solids till < 2 uC from combustion in boiler. Ash caught ESP that contents high mineral for raw material of ceramic, brick and organic fertilizers.
