Low Emissions and Efficiency Investigation of Pressurized Submerged Combustion Evaporator
The present investigation is concerned with the experimental determination of the influence of pressurized submerged combustion technology on thermal efficiency and pollutant emissions. Direct photography is to examine the global features of the flame created from an impinging injector faceplate outside the device. Gas analyzer is used to examine pollutant emissions, including CO, released from the system under conditions of four different submergences when the pressure above the surface liquid is 3 bars. Evidence is presented that pressurized submerged combustion technology as advanced designs of conventional submerged combustion can reduce NOX and CO emissions definitely. With the submergence increases, NOX emission is around 12 PPM. In the range of the excess air coefficient < 1, the results show that CO emission is about 5.56 PPM. NOX emission increases from 9.18 to 20.16 PPM as the excess air coefficient varies from 0.872 to 1.582, while CO emission reduces to zero. Therefore, it is the excess air coefficient, rather than the submergence, plays a key role in controlling the pollutant emissions. The evaporation of water has been carried out in this apparatus with the gross thermal efficiency of 95.2 per cent. The upshots of all these are that the whole process very efficient and environmental indeed.
