摘要

本研究比较了以液化天然气(LNG)、甲醇和二甲醚(DME)为燃料的玻璃熔窑低温余热回收换热器。采用1吨/年的玻璃熔窑与空气燃烧燃料，利用废热交换器低温回收烟气热量，对空气进行预热。净现值(NPV)和CO2排放量作为换热器的评价参数。结果表明，甲醇燃烧方案的净现值和CO2排放量最大。LNG燃烧程序给出的参数最少，二甲醚燃烧程序给出的参数居中。综合考虑换热器的收益和CO2的排放，以二甲醚为燃料的玻璃熔窑是最优方案。

Comparison of waste heat recovery exchangers of furnace combusted with different fuels

This work compares the low-temperature waste heat recovery exchangers of glass melting furnaces using liquid natural gas (LNG), methanol, and dimethyl ether (DME) as the fuel has been investigated. A glass melting furnace with 1t/year was used to combust the fuel with air, and the waste heat exchanger was served to recover the heat from the flue gas at a low temperature to preheat the air. The net present value (NPV) and CO2 emission acted as the evaluating parameter of the heat exchangers. The results showed that the methanol combustion program gave the maximum NPV and CO2 emission. The LNG combustion program gave the least ones, and the parameters in the DME combustion program are always in the middle. Considering the income of the heat exchanger and CO2 emission, the glass melting furnace with DME being the fuel is the most optimal program.
