Air burners the enviromentally friendly alternative to open burning

Yap H.C., . (2001) Air burners the enviromentally friendly alternative to open burning. [Proceedings Paper]

The disposal of waste vegetation such as tree trunks branches roots and leaves from land clearing and replanting activities is a major concern of the municipal and agricultural sectors. One method of disposal is to transport and bury the waste in a landfill. However the distance to landfills may make transportation cost prohibitive. Recycling efforts through compositing and mulching would help reduce the pressure on existing landfills but the process may be time consuming. Open burning of the vegetation waste on site is the simplest but it is the main cause of haze. The haze episode in 1997 was estimated to have caused the Malaysias palm oil industry to incur a drop in earnings of some RM 427 million due to a lower palm oil extraction rate resulting from the delayed ripening process. The bad air quality also made travelling difficult schools and airports had to close and many people suffered poor health and experienced breathing difficulties. Therefore there is a need to seek out an environmentally friendly alternative to open burning. Air Burners have been developed to permit the incineration of such vegetation waste while minimizing the amount of ash and smoke being released. 1. Air Burner nozzles directing high velocity air flow into refractory lined box or earthen trench. 2. Refractory lined wall or earthen wall. 3. Biomass waste to be burned. 4. High velocity air curtain over fire trapping particulates. 5. Continuous air flow over oxygenates the fire keeping temperatures high. A longer residence time ensures complete smokeless combustion. Environmental benefits of Air Burners: no smoke minimal particulates and residual ash can be used as soil amendments. Malaysias Department of Environment has given approval for the use of Air Burners for disposing wood waste generated from land clearing works.

Abstract

The disposal of waste vegetation such as tree trunks branches roots and leaves from land clearing and replanting activities is a major concern of the municipal and agricultural sectors. One method of disposal is to transport and bury the waste in a landfill. However the distance to landfills may make transportation cost prohibitive. Recycling efforts through compositing and mulching would help reduce the pressure on existing landfills but the process may be time consuming. Open burning of the vegetation waste on site is the simplest but it is the main cause of haze. The haze episode in 1997 was estimated to have caused the Malaysias palm oil industry to incur a drop in earnings of some RM 427 million due to a lower palm oil extraction rate resulting from the delayed ripening process. The bad air quality also made travelling difficult schools and airports had to close and many people suffered poor health and experienced breathing difficulties. Therefore there is a need to seek out an environmentally friendly alternative to open burning. Air Burners have been developed to permit the incineration of such vegetation waste while minimizing the amount of ash and smoke being released. 1. Air Burner nozzles directing high velocity air flow into refractory lined box or earthen trench. 2. Refractory lined wall or earthen wall. 3. Biomass waste to be burned. 4.
