It is a kind of waste heat boiler for pure low-temperature cement kiln waste heat power generation which fulfills the AQC tail gas waste heat recovery of 6000t/d clinker production of cement industry. This boiler can not only make effective use of the waste heat, but facilitate the operation of the following process, reducing the product cost and energy product, strengthening the company’s marketing competitiveness. Meanwhile, it also fit the national energy policy and will be an irresistible trend in the future.
