Guide: Recently, in order to continuously improve the environmental air quality in the jurisdiction, the relevant requirements of the "Zhejiang Province 2020 Implementation Plan for "Dual Control and Double Reduction" of Fine Particulate Matter and Ozone" have been implemented to effectively curb the aggravating trend of ozone pollution and fully win the decisive battle to defend the blue sky. The Environmental Branch made arrangements in advance to fully promote the low-nitrogen transformation of gas boilers.
Recently, in order to continuously improve the environmental air quality in the jurisdiction, the relevant requirements of the "Zhejiang Province 2020 Implementation Plan for "Dual Control and Double Reduction" of Fine Particulate Matter and Ozone" have been implemented to effectively curb the aggravating trend of ozone pollution and fully win the decisive battle to defend the blue sky. The Environmental Branch made arrangements in advance to fully promote the low-nitrogen transformation of gas boilers.
One is a comprehensive search and list management.
In conjunction with the special equipment registration platform of the District Market Supervision Bureau, we carried out multiple rounds of gas boiler inspection work. The survey showed that there are 36 industrial gas boilers of 1 steam ton and above, and 177.6 steam tons in the district. Establish a low-nitrogen retrofit task list for gas-fired boilers, and achieve "retrofits should be done as much as possible". All 36 boilers discovered by the exhaust model will be included in the remediation list. The nitrogen oxide emission concentration after the transformation is required to be controlled below 50 mg/m3. The nitrogen oxide emission concentration of newly built gas-fired boilers is controlled below 30 mg/m3 to ensure effective reduction of nitrogen oxide emissions.
The second is to mobilize quickly and propagate it from house to house.
Nanhu District actively mobilized enterprises to implement low-nitrogen transformation. Staff from the District Ecological Environment Bureau came to introduce the relevant knowledge of low-nitrogen transformation. In 2019, three enterprises were first to carry out pilot transformations. Under the premise of ensuring safe production, the total of the three enterprises was completed. Involving low-nitrogen transformation of 6 boilers. In order to effectively guide more companies to actively invest in gas boiler renovation, the District Ecological Environment Branch organized 36 companies involved in gas boiler low-nitrogen renovation to hold a training meeting, and invited Zhejiang Eco-Environmental Science Design Institute Experts explained in detail the background of low-nitrogen retrofitting of gas boilers, related policies, industry technology status, common problems and precautions to help companies solve practical difficulties.
Where is the future of coal-fired boilers?
The third is to keep an eye on the key points and consolidate responsibilities.
In order to ensure the solid development of the work, the District Ecology and Environment Bureau mobilized various entities and enterprises to establish a low-nitrogen transformation WeChat group. The entities will follow up one by one, report the rectification situation in time, and keep a close eye on it. Implement a daily report system for the enterprises included in the transformation plan, and regularly check the progress of the transformation work to ensure that the transformation tasks are completed within the time limit. Up to now, 28 units have been transformed, exceeding the transformation tasks assigned by superiors.
The fourth is policy support to reduce the burden.
In order to support the stable and healthy development of enterprises and solve the cost problems faced by enterprises in the process of low-nitrogen retrofitting of gas boilers, Nanhu District formulated detailed implementation rules for supporting enterprise green development policies, and provided financial subsidies to eligible enterprises to promote the smooth implementation of low-nitrogen retrofits.
What is the difference between coal-fired boilers and gas-fired boilers? Why should coal-fired boilers be eliminated?
Next, the District Eco-Environmental Branch will further increase the on-site guidance of the “Three Services” to ensure the smooth completion of the annual task of low-nitrogen renovation of gas boilers, effectively improve the environmental air quality of the entire district, and ensure the successful completion of the “Blue Sky Defense” three-year action plan task .
