Core Viewpoint - The company has successfully implemented a revolutionary measure by utilizing a semi-waste gasification furnace to replace a traditional boiler, leading to significant cost reduction and efficiency improvement in its operations [1][2][3]. Group 1: Operational Achievements - In the second quarter, the semi-waste gasification furnace produced 12,240 tons of by-product steam, reducing coal consumption by 15,400 tons and cutting carbon dioxide emissions by 32,100 tons, resulting in an economic benefit of approximately 7.7 million yuan [1]. - The company successfully integrated high-pressure steam from the gasification furnace into its main steam network, allowing for the shutdown of one boiler by July 11, 2024, marking a significant milestone in its high-quality development strategy [1]. - The semi-waste gasification furnace has demonstrated a 5% increase in overall thermal efficiency and a 10% reduction in comprehensive energy consumption compared to traditional gasification furnaces [2]. Group 2: Technical Innovations - The company has addressed various technical challenges related to the semi-waste gasification furnace, including sealing, blockage, and localized overheating, which has led to improved heat exchange efficiency and stable long-term operation [1][2]. - After 90 days of operation, the steam output from the semi-waste gasification furnace maintained a level not lower than 80 tons per hour, providing a solid foundation for the boiler shutdown [2]. Group 3: Environmental Impact and Future Plans - Over the course of one year since the boiler shutdown, the company has reduced carbon dioxide emissions by 106,000 tons and generated economic benefits of over 25 million yuan [3]. - The company is actively compiling operational data and experiences from the past year to promote this model within the Shandong Energy Group and the broader coal chemical industry, contributing to green, low-carbon, and high-quality development [3].
