Coal fired boiler in the production process will produce a lot of flue gas, which contains pollutants, such as sulfur dioxide and nitrogen oxides, will have adverse effects on the environment and human health. The presence of these pollutants will lead to acid rain, which will have a corrosive effect on soil, water and buildings, but also aggravate air pollution and affect air quality.
Therefore, it is very necessary to treat the flue gas of coal-fired boilers. At present, the common flue gas treatment technologies include electric dust removal, desulfurization and denitrification. Electrostatic precipitator is an efficient dust removal method, it uses electrostatic force to separate the dust in the flue gas, can directly act on the dust particles, without the need for greater airflow resistance, so the dust removal efficiency is higher. In addition, China’s existing denitration, flue gas dust removal technology is simple, can realize the whole process of automatic control, can reduce the workload of boiler workers in power plants, and the operating cost is low. However, while these technologies have their own advantages, there are also some challenges, such as the electrostatic precipitator equipment occupies a large space and requires a large investment.
The SCR denitrification system independently developed by GRVNES can meet the latest national environmental requirements, ultra-low nitrogen oxide emissions and ammonia escape requirements of less than 3ppm. We can use the corresponding technology and product process according to the flue gas, working conditions and pollution characteristics of different industries, and customize targeted solutions. With excellent technical strength and technological level, rich experience in environmental protection projects and strong technical service team, To provide more industry customers with good social and economic benefits of environmental pollution prevention and control system overall solution.
