June, all parts of the country began to enter the rainy season, and the cement industry ushered in the traditional off-season sales, which further increased the pressure on cement prices to fall, and cement prices in some areas have fallen below the cost line of enterprises. Recently, the transaction price in some parts of East China has approached about 300 yuan/ton. & nbsp; & nbsp;
The cement market is in the doldrums, the peak season is not prosperous, and the off-season is even weaker. The price of cement is at a low level, but at the same time, the price of coal is high, and the cost pressure of enterprises is huge, which further squeezes the profit margin and makes it difficult for enterprises to survive. & nbsp; & nbsp;
Alternative fuels ease cost pressures for cement companies & nbsp; & nbsp;
Coal and electricity are the main sources of energy for the cement industry and typically account for about 50% of the total cost of cement production. But in 2021, the price of coal soared from less than 600 yuan per ton to nearly 2000 yuan, which was once nicknamed "coal super crazy". In the
past two years, with the rise of coal price, the production cost of cement enterprises is under great pressure, and enterprises are also thinking about how to deal with it. Especially under the requirements of the double carbon target, the cement industry will soon be incorporated into the carbon trading system, the future carbon dioxide emission rights need real gold and silver to support, the cost impact on enterprises is gradually increasing, the use of alternative fuels is the general trend. Most cement companies have begun to actively explore and gradually use alternative fuels.
Alternative fuel, also known as secondary fuel and auxiliary fuel, refers to the use of combustible waste as cement kiln clinker production to replace natural fossil fuel. The application of combustible waste in cement industry can not only save primary energy, but also contribute to environmental protection, with significant economic, environmental and social benefits. Data show that if 40% of alternative fuels are used in cement production, about 100000 tons of carbon dioxide will be saved for every 1 million tons of clinker produced. Gao Yuzong, senior consultant of
China Cement Network, has said that the cement manufacturing industry is a major energy consumer and carbon emitter in the building materials industry. At present, many cement enterprises have begun to use alternative fuels in pursuit of reducing production costs and carbon emissions. Through the transformation of green, low-carbon and environmental protection, we can strive for more benefits and living space for enterprises themselves.
In recent years, many cement enterprises, such as Conch Cement, Tianshan Cement, Huaxin Cement and Tapai Group, are accelerating the promotion of non-fossil energy alternative fuels and promoting the greening of energy structure. On March 22,
2023, Luoyang Zhonglian began to recycle waste mushroom sticks and branches from the local mushroom base, crushed them by crusher, transported them to the hot plate furnace by belt, and burned them in the hot plate furnace; The heat aft combustion enters that cyclone through the decomposition furnace for heat exchange, so as to achieve the purpose of replace fossil fuels with biomass fuels. The use of
biomass fuel can effectively reduce the use of raw coal, so as to achieve the effect of energy saving and carbon reduction, which can not only save costs, but also be low-carbon and environmentally friendly. According to the analysis of the current use situation, the use of 3 tons of biomass fuel per hour can reduce 1 ton of raw coal, thus reducing 2.25 tons of CO2 emissions, and the local biomass fuel alone can reduce 2370 tons of CO2 emissions per year.
Previously, the White Paper on Low Carbon Development released by Huaxin Cement showed that in 2022, Huaxin Cement used a total of 3.87 million tons of alternative fuels, and the combined calorific value substitution rate of domestic factories has reached 15.9%; Through the implementation of quality analysis and batching optimization of alternative raw materials, 2.2359 million tons of non-carbonate industrial waste residues were comprehensively utilized throughout the year. By the end of 2022, Huaxin Cement has used more than 15 million tons of waste-derived alternative fuels safely and ecologically, and the thermal substitution rate of all kiln lines in China has reached 15%.
It is understood that following the development and construction of biomass alternative fuel system in Battambang Conch, Cambodia in 2018, Conch Group completed the first biomass alternative fuel project in the domestic industry in Zongyang Conch in 2020. After the project is put into operation, 84,000 tons of standard coal will be saved and 200,000 tons of carbon dioxide will be reduced.
Under the comprehensive background of "double carbon" target, marketization of electricity price and high coal price, more and more listed cement enterprises have gradually increased the proportion of "green energy" by increasing efforts to explore alternative fuels and renewable energy to reduce fossil fuel combustion and power consumption. This will not only enhance their ability to cope with external risks, but also help the cement industry to take the lead in achieving carbon peak and carbon neutralization. On July 6-7,
2023, China Cement Network will hold the "2023 China Cement Energy Conservation and New Energy Development Conference" in Chongqing. Deeply tap the energy-saving potential of cement enterprises, expand the application of photovoltaic and energy storage technologies, promote the transformation of green electricity and alternative fuels to replace traditional energy, and help cement enterprises to enhance their comprehensive strength and market competitiveness.
