主 题：Smoke heat recovery Smoke extract process Heat transfer Soot thermal efficiency
摘 要：Over the course of industrial manufacturing,additional heat within the extract systems is usually released into the atmosphere and its intrinsic energy is *** paper investigated a cold abatement smoke extract system for a fire testing wall furnace to determine the viability in recovering heat from the hot *** scenarios were investigated:1)the extract system was closed and only 300°C smoke was present;2)the system took in ambient air around the furnace and heat recovery occurred at 80°C in smoky air;3)the smoke had been removed from the air and the temperature was 60°*** was found that there was a significant build-up of soot on Scenarios 1&2 with a build-up rate of 0.25𝜇m/s which totalled 2.7 mm of soot after a three-hour *** soot had a low heat transfer rate and therefore acted as an insulator on the heat exchanger which reduced the efficiency significantly of it over *** to this loss in efficiency,it was more viable to recover heat in Scenario 3 at 60°C in clean air than it was to recover heat at 300°C or 80°C in smoky *** results show that having clean air was more important than a higher temperature when it came from recovering heat from a cold abatement system for a fire testing *** paper contributes to reveal the possibilities of harnessing the“waste heatfor use in other applications in the vicinity of the manufacturing processes,such as heating water within a central heating plant,domestic hot water or electricity generation,or re-cycled within the industrial plant itself.
