Summary of data on modification of combustion system of Jinghua galvanizing line：    

       According to the production data before and after the combustion system transformation provided by Tangshan Jinghua, compared with the original combustion system, after using our low-nitrogen combustion system, the total output increased by 51.6%, the total gas consumption was saved by 65.2%, and the energy consumption per ton was saved by 1.5m³ of natural gas. The specific data are shown in Table 1.

       In order to ensure the accuracy and authenticity of the NOx emission values, Tangshan Jinghua organized and arranged a third-party testing agency to conduct testing. Two sets of data, one is the one-hour average NOx value detected using the original combustion system and denitration equipment running; the other set is the one-hour average NOx value detected after using our company's combustion system without running denitration equipment. The specific detection values are as follows Shown in Table 2：

Customer usage feedback：

Reduce costs：

1. After transforming the combustion system, it meets the emission standard of Nox≤30mg/m³, saving 6.3 million yuan in operation and maintenance costs for out-of-stock equipment;

2. The burner flame is stable, the furnace temperature is evenly distributed, the thermal efficiency is high, and the energy consumption is reduced. Based on an annual output of 1 million tons, it can save 3.9 million yuan in natural gas costs.

Green：

1. Actual measured NOx≤30mg/m³, the lowest Nox value can reach single digits;

2. Based on an annual output of 1 million tons, carbon emissions will be reduced by 3,000 tons compared to before the transformation.
