Mixed Combustion of Hydrogen, Double Reduction of Carbon and Nitrogen! EBICO is One Step Ahead to Achieve 2030 "Carbon Peak" Goals.

Chlor-alkali industry is one of the most basic chemical industries. With the implementation of "double carbon" economic strategy in China, the whole chlor-alkali industry is also facing the transformation of development mode and industrial structure adjustment. The equipment capacity and environmental protection technology of chlor-alkali industry are improving day by day, and it is developing towards the direction of environmental protection, low carbon and low energy consumption.

Low-carbon development is the general trend of our country,and also the international trend. The environment-friendly and low-carbon sustainable development ability of enterprises will surely become an important competitiveness of an enterprise. In terms of nitrogen reduction, EBICO has been leading the market. Now that the double-carbon era is coming, EBICO is duty-bound to lead the trend of carbon reduction market and earnestly fulfill its social responsibility.

Lutai Chemical Co., Ltd., a wholly-owned subsidiary of Shandong Lutai Holding Group, is mainly engaged in chemical production. In order to further extend the industrial chain, they started the 100,000 ton/year evaporation flake caustic soda project, thus further optimized the caustic soda product structure. As a leading company in eco-friendly combustion equipment, EBICO took a great part in this project.

The 5.5 million kcal molten salt furnace of this project chose to use EBICO automatic ultra-low NOx electronic ratio controlled hot air burner. An electronic proportional control system is adopted to adjust the air/gas ratio, and two actuators are used to control the damper, gas valve and external circulation valve respectively, so as to realize the full combustion of gas and synchronously adjust the ratio of air/gas/circulating air.

The EBICO technical team selects the burner model EC6GR which can perfectly meet the requirements of molten salt furnace. It’s in the form of THF split machine. Under the regular air temperature, the maximum output is 950-9500kw, the hot air temperature is up to 290℃, and the maximum output is 7500KW.

EBICO has solved the safety and environmental protection problems perfectly through its unique technology. Considering hydrogen has a fast combustion speed, a wide explosion limit and a high initial nitrogen oxide emission, so in this project, fuel is provided by mixed combustion of natural gas and hydrogen, and the two gases enter the burner through separate pipelines.

At the same time, a flue gas re-circulation system is set to recycle part of flue gas into the burner for reuse. Because the flue gas absorbs heat and dilutes the oxygen concentration, the combustion speed and the temperature in the furnace are reduced, so the thermal NOx can be reduced by 50-70%. In addition, the carbon reduction effect will be significantly enhanced when the clean energy hydrogen is mixed with natural gas. The double reduction of carbon and nitrogen provides a strong driving force for Shandong Lutai to build an intelligent factory of environmental protection and emission reduction.
