On March 1, the Yunnan Development and Reform Commission issued the List of Provincial Major Projects in Yunnan Province in 2023 and the List of "Top Priority" Projects in Yunnan Province in 2023. The industrial category includes the 4,628t/d new dry process cement clinker production line (with 9 MW pure low-temperature waste heat power generation) project of Maitreya Hongshi Cement Co., Ltd. and the 4,000t/d clinker project of China Resources Cement (Heqing) Co., Ltd.

On March 1, the Yunnan Development and Reform Commission issued the List of Provincial Major Projects in Yunnan Province in 2023 and the List of "Top Priority" Projects in Yunnan Province in 2023, including 134 transportation construction projects and 204 urban construction projects.

Among, The industrial category also includes the 4,628t/d new dry process cement clinker production line (with 9 MW pure low-temperature waste heat power generation) project of Maitreya Hongshi Cement Co., Ltd. and the 4,000t/d clinker project of China Resources Cement (Heqing) Co., Ltd.

Maitreya Hongshi Cement Co., Ltd. 4628t/d new dry process cement clinker production line (with 9MW pure low-temperature waste heat power generation) project:

It is reported that the project covers an area of 679.95 mu, with a total investment of about 1.62 billion yuan . A cement clinker production line with a daily output of 4628 tons will be built by adopting the new dry decomposition production process , supporting 9 MW pure low-temperature waste heat power generation project, 200000 tons/year solid (hazardous) waste project and 5 million tons/year aggregate mine project. Supporting construction of public auxiliary facilities such as raw material storage yard, limestone homogenization warehouse, packaging, bulk, water, electricity and office area. The project is scheduled to be ignited and put into operation in December 2023.

According to the Department of Industry and Information Technology of Yunnan, Maitreya Hongshi Cement's 4,628t/d clinker production capacity replacement project is as follows:

China Resources Cement (Heqing) Co., Ltd.'s 4,000t/d clinker production project:

Project construction content and scale: China Resources Cement (Heqing) Co., Ltd. The project implements technical transformation on the existing first-line 2500 tons/day clinker production line. After the technical transformation, the clinker production capacity is 4000 tons/day. A pure low-temperature waste heat power station with rated power of 10 MW is built. After the technical transformation, the second-line 2500 tons/day clinker production line is shut down. The main construction contents of

the project include combined storage, raw material grinding, kiln grinding waste gas treatment, rotary kiln, clinker cooling, pulverized coal preparation, kiln head waste heat boiler, kiln tail waste heat boiler, etc. Through the replacement of capacity reduction, the original 2 * 2500 tons/day clinker production line is transformed into 4000 tons/day clinker production line , with an annual output of general Portland cement clinker 1240000 tons and cement 1534748 tons. The project is scheduled to be put into operation in 2024. When the

project is completed, the annual comprehensive energy consumption will be 129034 11 tons of standard coal (equivalent value) and 142638 40 tons of standard coal (equivalent value). The comprehensive coal consumption per unit product of clinker is 93.68 kg standard coal/ton, the comprehensive energy consumption per unit product of clinker is 99.63 kg standard coal/ton, the comprehensive power consumption per unit product of clinker is 48.40 kWh/ton, the comprehensive energy consumption per unit product of cement is 83.99 kg standard coal/ton, and the power consumption of cement preparation section is 28.40 kWh/ton. Energy consumption per unit of industrial added value is 6.99 tons of standard coal/10,000 yuan.

According to the Department of Industry and Information Technology of Yunnan Province, the clinker production capacity replacement project of China Resources Cement (Heqing) is as follows:
