Coal-fired power plants, as a major component of China's power supply, have caused severe air pollution issues. Under the background of energy conservation and emission reduction, various measures are being taken by major coal-fired power plants across China to lower nitrogen oxide emission standards.

Under the requirements of environmental protection policies, industries now also attach great importance to energy conservation and emission reduction measures. Low nitrogen combustion technology has certain advantages in environmental protection, but it also has some impact on the operation of boilers. Therefore, it is necessary to further strengthen the handling measures for problems in new environmental protection technologies to secure the most effective environmental protection mechanisms for industrial sustainable development. The stability of boilers is reflected in many aspects, with the most significant being the stability of temperature and the sealing of the butterfly valve during operation.

The smoke plug valve plays a crucial role in the operation of boilers. Mainly used in the inlet and outlet or bypass flue gas ducts of the flue gas desulfurization system's absorption tower, it is designed to isolate flue gas flow and can also be applied to other flue gas ducts with high operating isolation requirements. Suitable for industries such as chemicals, petrochemicals, metallurgy, papermaking, and power. The sealing property is a key indicator of the smoke plug valve's function, ensuring there are no internal or external leaks during use; a gas tightness of over 99% is a professional flue valve's standard. Among various types of flue valves, the editor recommends using the electro-hydraulic smoke plug valve. During installation, the smoke plug valve is outside the flue, reducing corrosion and deformation due to high temperatures. The electro-hydraulic drive method provides strong thrust and pull, eliminating the issue of sticky and inflexible operation.

Dezhou Zhongsheng Environmental Protection Technology Co., Ltd. has independently developed an electric hydraulic smoke gas plug valve with strict airtightness, no internal or external leakage, smooth operation without sticking, and a long service life, achieving an airtightness of over 99%. In today's increasingly severe environmental situation, Zhongsheng Environmental Protection is willing to unite with all sectors of society to shoulder the responsibilities of society and history, and promote the progress of human civilization.
