One is to strengthen the development and application of cutting-edge technologies and cultivate benchmark demonstration enterprises. At present, the domestic production of calcium carbide adopts the electric smelting process. In order to reduce the process electricity consumption and comprehensive energy consumption of calcium carbide unit products, promote the diversification of calcium carbide production process routes, the Implementation Guidelines propose to strengthen the research and development of new technologies and processes such as oxygen heating and electromagnetic methods, and timely construct pilot and industrial facilities. At the same time, it is necessary to strengthen the research and development, promotion and application of calcium carbide sensible heat recovery and efficient utilization technology, and reduce comprehensive energy consumption.

The second is to accelerate the popularization and promotion of mature processes, and orderly promote transformation and upgrading. The Implementation Guidelines propose to promote the promotion and application of new pyrolysis pellet processes, and reduce the process power consumption and comprehensive energy consumption per unit product of calcium carbide. Promote the use of high-efficiency insulation materials in calcium carbide furnaces, effectively reducing heat loss of the furnace body and reducing electricity consumption.

The third is to improve the utilization level of resources such as furnace gas. Calcium carbide furnace gas is rich in carbon monoxide and is a high-quality chemical raw material, but currently it is mainly used for direct combustion of lime kiln fuel. The Implementation Guidelines propose to promote the comprehensive utilization and transformation of carbide furnace gas resources, using technologies such as biological fermentation for ethanol and chemical synthesis for ethylene glycol, dimethyl ether, methanol, etc., to promote the utilization of carbide furnace gas as a chemical raw material and reduce carbon dioxide emissions.

The fourth is to strengthen the recovery and utilization of waste heat and pressure. The Implementation Guidelines point out the need to promote advanced waste heat recovery technology, use heat pipe technology to recover waste heat from carbide furnace gas for power generation and other purposes, and improve the level of waste heat utilization. Strengthen the recovery and utilization of waste heat from lime kiln exhaust gas and purified ash from calcium carbide furnace, as supplementary heat sources for carbon drying equipment, and reduce energy consumption throughout the entire calcium carbide production process.

The fifth is to eliminate outdated and inefficient production capacity. The Implementation Guidelines require strict implementation of relevant laws and regulations on energy conservation, environmental protection, quality, safety and technology, as well as policies such as the Industrial Structure Adjustment Guidance Catalog, to phase out internal combustion calcium carbide furnaces, and guide invalid calcium carbide production capacity that has been shut down for a long time to voluntarily exit. Production devices with energy efficiency levels below the benchmark value and unable to achieve above the benchmark value through energy-saving transformation should be phased out and phased out at an accelerated pace.

It has been proven that promoting the application of calcium carbide furnace gas analysis system in closed calcium carbide furnaces can promote production enterprises to save production costs, ensure the safe operation of calcium carbide furnaces, and thus facilitate the promotion of large closed furnaces and accelerate the progress of internal combustion calcium carbide furnace transformation. It is one of the important measures for optimizing the industrial structure, improving the level of technical equipment, and completing energy conservation and emission reduction tasks in China's calcium carbide industry.

The application of the calcium carbide furnace gas analysis system can improve the efficiency of tail gas recovery and utilization in closed calcium carbide furnaces, achieve energy-saving, consumption reduction, and emission reduction goals. The main component of carbide furnace gas is carbon monoxide, about 70% or higher, and it also contains carbon dioxide, hydrogen, methane, and oxygen. The CO generated by internal combustion calcium carbide furnaces cannot be comprehensively utilized and can only be emitted after combustion, resulting in a large amount of energy waste and exacerbating CO2 greenhouse gas emissions. After the recovery of tail gas from the sealed calcium carbide furnace, it can be used as boiler fuel or for producing lime in gas fired lime kilns. For every 1 ton of calcium carbide produced in a closed calcium carbide furnace, the available CO gas is equivalent to approximately 160 kilograms of standard coal. If the enterprise has a large production scale, it can also use CO to produce various chemical products, such as sodium formate or methanol, and achieve a reduction of 680 kilograms of CO2. The TR-9700 calcium carbide furnace gas analysis system adopts the advanced non spectral infrared principle imported from Siemens, Germany to monitor the concentration of CO and CO2, which can effectively eliminate cross interference between gases. The testing accuracy is as high as 1%, which is beneficial for guiding enterprises to save costs, improve furnace gas utilization, and achieve energy-saving and emission reduction indicators.

The application of the calcium carbide furnace gas analysis system can monitor the increase in H2 concentration caused by water leakage, achieving monitoring of the safe operation of closed calcium carbide furnaces. The safety operation of sealed calcium carbide furnaces is a problem that production enterprises must consider, and it is also one of the main reasons for the slow promotion of sealed calcium carbide in recent years. The enclosed calcium carbide furnace requires cooling, and the second layer furnace cover, water-cooled sleeve, bottom ring, and contact components of the calcium carbide furnace are all water supply equipment, which poses many safety hazards. Water cooling components often experience water leakage due to poor sealing or aging. It is difficult to detect water leakage in a sealed calcium carbide furnace, and water vapor is difficult to discharge, which can easily decompose into hydrogen gas at high temperatures in the furnace. When the concentration is too high, it can lead to explosion accidents. The TR-9700 calcium carbide furnace gas analysis system uses an imported Siemens C6 thermal conductivity principle analyzer from Germany to monitor the H2 concentration in the furnace gas and monitor water leakage in real-time.

The TR-9700 furnace gas analysis system can simultaneously measure CO, CO2, H2, and O2, thereby improving the comprehensive utilization and recovery efficiency of furnace gas, guiding combustion measurement and control, and playing an important guiding role in achieving energy-saving and emission reduction indicators for production enterprises.
