In the cement clinker calcination process, there is a large amount of heat contained in the exhaust gas discharged from the kiln head cooler and kiln tail preheater, with the heat contained in the low-temperature exhaust gas below 400°C accounting for about one-third of the total heat consumption in cement clinker calcination. Waste heat power generation technology can save a lot of resources and energy by recovering this part of waste heat, and it will not cause secondary pollution to the environment. Therefore, waste heat power generation technology has become a new technology in the cement industry, which is an effective way to achieve pollution reduction, energy conservation, efficiency improvement, and sustainable development. 年发电量。年发电能=（6.12E+7）kwh×（3.60E+6）J/kWh=（2.20E+14）J。在水泥熟料嫩烧过程中，从窑头冷机和窑尾预热器排出的废气中蕴含着大量的热量，其中400C以下的低温废气所含的热量占水泥熟料烧总耗热量的三分之一左右。余热发电技术通过回收这一部分的余热，可以节约大量的资源、能源，并且不会对环境产生二次污染，因此，余热发电技术已成为水泥行业的新兴技术，是实现其减污、降耗、增效以及可持续发展的有效途径。 cement, ordinary portland cement Output 1000.0 1000.0 Cement products 水泥产品
