摘要

为响应国家“双碳”“双减”目标，促进高耗能企业节能减排，以解决我国陶瓷行业窑炉排烟热损失较大的问题。以某窑炉排烟余热 (220～250 ℃) 的陶瓷企业为研究对象，采用有机朗肯循环 (ORC) 低温余热发电方案，并对其进行经济效益与减排效益分析。结果表明：在陶瓷行业内，使用 ORC 发电技术对窑炉烟气进行余热回收具有技术可行性；当 ORC 发电效率为 15%时，该企业年节约电费为 991.6 万元，年节能效率可达 6%，经济效益较为可观，且 CO

、SO

、NO

的减排量分别为 4 693.3、15.2、13 t，整体减排效益显著。该技术符合“双碳”政策、绿色可持续经济发展的方向，其未来市场空间广阔。

Abstract

In order to respond to the national goal of "double carbon" and "double reduction" and to promote energy saving and emission reduction in high energy-consuming enterprises

the problem of large heat loss from kiln exhaust in China’s ceramic industry was solved. A ceramic enterprise with kiln exhaust waste heat （220-250 ℃ ） was studied

and an organic rankine cycle （ORC） low-temperature waste heat power generation scheme was used

and its economic and emission reduction benefits were analyzed. The results showed that it was technically feasible to use ORC power generation technology to recover waste heat from kiln flue gas in the ceramics

industry; when the ORC power generation efficiency was 15%

the annual electricity cost saving of the enterprise was 9.916 million yuan

and the annual energy saving efficiency was up to 6%

which was a considerable economic benefit. And the emission reductions of CO

and NO

were 4 693.3

15.2 and 13 t respectively

and the overall emission reduction benefits were remarkable. This technology is in line with the "double carbon"policy and the direction of green and sustainable economic development

and its future market space is broad.
