Project introduction:

In response to climate change, many countries have made carbon neutral commitments and actively sought a green and low-carbon development path. Energy consumption is the largest source of carbon emissions, and coal-fired power is the largest source of carbon emissions from energy consumption. Therefore, reducing CO2 emissions from coal-fired units is the key to achieving carbon neutrality.

The purpose of the entries is to change the traditional high carbon emission coal-fired power generation mode, innovate the fuel source, explore the use of green and clean zero carbon ammonia fuel to replace a certain proportion of coal, achieve the goal of significantly reducing CO2 emissions, and provide a source carbon reduction solution for coal-fired units. This work has made original breakthrough achievements, developed the low-carbon technology of mixed ammonia combustion in coal-fired boilers, and developed a large-scale ammonia coal mixed combustion low-nitrogen burner by using the multi-point mixed combustion jet technology, which can coordinate the different ammonia injection modes and proportions in the furnace, and achieved the industrial verification of mixed ammonia combustion with the largest scale and the highest mixed ammonia ratio of 35% for the first time in the world.

At present, 11 patents have been applied for this product, of which 6 have been authorized; One paper was published. According to the review of China Society of electrical engineering and China Petroleum and Chemical Industry Federation, this technology is the first time in the world to achieve 35% mixed ammonia ratio in 40MWth coal-fired boiler, reaching the international leading level. It provides a feasible technical development direction for coal-fired units to achieve CO2 emission reduction, and plays a significant role in promoting the realization of double carbon strategic goals. In January 2022, it was reported by CCTV and other media.

This technology can realize the organic combination of green ammonia and coal. From the perspective of complementary advantages, it can solve the dual problems of energy storage and consumption of renewable energy and the maintenance of traditional coal-fired units. This product conforms to the principle of low-carbon energy cooperation among BRICS countries and has the potential for cooperation and promotion.
