3. Small biomass power plant prototype for the communities
The small biomass power plant “Suranaree” has an output of 100 kW. It uses biomass gasification (open-top downdraft gasification) by feeding biomass from above and causing incomplete combustion by controlling the volume of air and amount of oxygen. Solid biomass fuel is then converted to a gas containing 18-22% carbon monoxide (CO), 18-20% hydrogen (H2), and 1-2% methane (CH4) with an average heat value of 4.5-5.5 MJ/m3. It can serve as a substitute for petroleum or natural gas. Gas fuel, which is produced through cleaning sticky rubber and dust (tar and dust) and reducing the temperature, can be used as fuel for the internal combustion engine. It can produce 40,000 kWh/year of electricity.
4. MW waste-to-fuel power plant
The university’s Plasma Gasification Power Plant is currently being tested. It uses fixed-bed downdraft gasification technology and an additional heat source from the plasma system using waste fuel. The power plant consists of 5 main components: 1) a waste fuel conveying system, 2) a fuel gas production system, 3) a gas cleaning system, 4) a wastewater treatment system, and 5) a control system and power generation engines.
The Plasma Gasification Power Plant can continuously control the temperature in the furnace, which affects the efficiency of waste disposal through plasma arc technology. The release of electricity transfers energy to O2 and N2 molecules in the air, causing an increase in heat. As a result, gas molecules break down and atomize. In the plasma state, the temperature reaches values above 2000° C, which is sufficient for the disposal of solid waste and even infectious waste containing a variety of elements of high physical and chemical variance. Used with a gasification combustion system, which feeds only 30% of the air needed in the combustion reaction, synthetic gas of high quality is produced. This gas can be used as fuel for internal combustion engines and to power coils rotating in a magnetic field to generate electricity in an efficient and environmentally safe way.
