For the grain and oil industry, boilers are the lifeblood of production. Ranging from rice drying and flour processing to oil pressing, they provide energy for key processes such as drying, cooking, and pressing. However, the combustion process of boilers generates a large amount of nitrogen oxides (NOₓ), which not only cause multiple harms to the environment.
In response to the characteristics of boilers in the grain and oil industry—including “significant fluctuations in operating conditions, compact spatial layout, and the need to balance production efficiency with environmental protection requirements”—Lvgu Environmental Protection’s SCR denitration technology achieves a balance between precise pollutant removal and production efficiency. The team of Lvgu Environmental Protection first conducts an in-depth diagnosis of the combustion system of grain and oil boilers, and customizes low-modification solutions based on the load variation patterns of different grain and oil processing links (e.g., wheat drying and oil pressing).
Lvgu Environmental Protection’s SCR system is equipped with an intelligent control system. By real-time monitoring parameters such as boiler load, flue gas temperature, and NOₓ concentration, it automatically adjusts the injection volume of the reducing agent (ammonia), preventing secondary pollution caused by excessive reducing agent or non-compliant emissions due to insufficient reducing agent. According to actual operation data, the NOₓ emission concentration of grain and oil boilers is stably controlled at 20mg/m³, meeting the ultra-low emission requirement. This figure is far lower than the national standards for key regions, and the denitration efficiency has been maintained at over 90% for a long time, fully complying with environmental protection requirements.
SCR Denitration Transformation for Boilers in Hubei’s Grain and Oil Industry
- Flue Gas Volume: 800Nm³/h
- Model: GRVNES-GLYX-12
- Emission Reduction: Reduced from 150mg/m³ to 20mg/m³
GREEN VALLEY Environmental Protection will continue to deepen its focus on the denitration field of the grain and oil industry, increase investment in technological R&D, and lower the threshold of environmental protection investment for small and medium-sized grain and oil enterprises. Additionally, it will reuse the heat generated during the denitration process in the grain and oil drying link to further improve energy utilization efficiency.
