An assessment for the viability of recovering heat from a smoke extract system

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