Garden waste disposal in the military barracks
Keywords:
Incinerators, Garden waste, Packed bedAbstract
BY MODEL OF PACKED BED INCINERATOR Currently, at military barracks, domestic solid waste is mainly treated by two main methods: landfilling and burning. The application of these two methods in units is not environmentally safe due to unsanitary burial and natural burning, polluting the environment and affecting the health of soldiers. This study aims to test the packed bed incinerator to propose a treatment option for garden waste to minimize the impact on the surrounding air environment. With the advantage of being easy to operate and low investment costs, the packed bed incinerator was selected for researching because it is suitable for the actual conditions at military units. To select the right conditions, the study was conducted with 4 air supply modes and different states of garden waste. The initial study results with garden waste samples on the 5 kg/h capacity model show that increasing the air supply will shorten the treatment time. With the air supply speed of 0.3 m/s, the burning time is 22 minutes faster than when burning at the air supply speed of 0.08 m/s with a burning time of 30 minutes. The measurement results of pollution parameters in the exhaust gas such as CO, NOx and SO2 all have low pollutant concentrations at low levels, showing that the packed bed incinerator is capable of effectively treating garden waste.
