- It is typical of burning biodegradable materials such as husks, cores, and chaff or disposing these waste materials by burial (i.e., landfill). Regarding burning, it may pollute air. Regarding landfill, it may occupy precious land and pollute ground water. The scale of burning above biodegradable materials is small worldwide. Further, burning efficiency is low. Furthermore, it is difficult of disposing the resultant ash. Thus, the need for improvement still exists.
- It is therefore one object of the invention to provide a combustion system for biological materials including husks, cores, and chaff, the combustion system can be employed as an environmentally friendly heat source for many applications.
- To achieve the above and other objects, the invention provides a system for a combustion mixture of fuel, air, and particles of solid biodegradable materials including husks, cores, and chaff, comprising a feed unit comprising, from upstream to downstream, a pulverizer, a hopper, and a pneumatic conveyor; an air delivery unit comprising, from upstream to downstream, a vortex blower, an air tank, and an air volume regulator; a heating unit comprising, from upstream to downstream, a fuel source, a fuel flow control, and a heater; a combustion unit heated by the heater, the combustion unit being adapted to receive particles from the pneumatic conveyor and compressed air from the air volume regulator; and a nozzle at an outlet of the combustion unit, wherein the particles and the compressed air are mixed in the combustion unit turbulently to fully combust when the combustion unit is heated to a temperature between about 400° C. to about 1,350° C.
- By utilizing the invention, a number of advantages including fully use of typically useless husks, cores, and chaff as an environmentally friendly heat source, decreasing air pollution, decreasing sites for landfill, and saving energy can be obtained.
- The above and other objects, features and advantages of the invention will become apparent from the following detailed description taken with the accompanying drawings.
