The hottest response to the busy denitration of bo

In response to the busy denitration of boilers in national shitiao paper mill,

in the first half of this year, the domestic blockbuster "ten hazes" was grandly released in Beijing. For a while, it was dark and the masks were out of stock. On September 10, 19 primary school students in Yueqing City, Zhejiang province suffered from collective nosebleed caused by harmful gases from chemical factories, and the problem of air pollution was pushed to the forefront again. Coincidentally, on the same day, the State Council issued the action plan for the prevention and control of air pollution

the action plan for the prevention and control of air pollution (hereinafter referred to as the "action plan") is also known as the "national ten articles". While the people have high hopes for its beautiful vision, the paper industry, together with the steel industry, petrochemical industry, cement industry and other two high and one capital (high energy consumption, high pollution, resource-based) industries, has become one of the focuses of the action plan

one common feature of the above industries is that coal-fired boilers play an indispensable role in their production process. As far as the paper industry is concerned, large paper mills are basically equipped with electric heating projects. As the main force of these electric heating projects, whether coal-fired boilers use high-efficiency, energy-saving and environmental friendly boilers and whether they are equipped with boiler desulfurization and denitration projects determine whether the project causes significant harm to the atmospheric environment and even determines the quality of life of people

it is expressly required in the ten national articles to speed up the construction of desulfurization, denitration and dust removal transformation projects in key industries. All coal-fired power plants, sintering machines and pellet production equipment of steel enterprises, catalytic cracking units of oil refining enterprises, and non-ferrous metal smelting enterprises should install desulfurization facilities, and coal-fired boilers with 20 steam tons or more per hour should implement desulfurization. All coal-fired units except the circulating fluidized bed boiler should be installed with denitration facilities. The new dry process cement kiln should implement the technical transformation of low nitrogen combustion and install denitration facilities. The existing dust removal facilities of coal-fired boilers and industrial kilns should be upgraded

in short, the national ten articles stipulates that small coal-fired boilers with less than 10 steam tons per hour should be phased out, and coal-fired boilers with more than 20 steam tons per hour must be transformed and installed with desulfurization facilities, and all coal-fired boilers should be installed with denitration facilities

once the "national ten articles" was issued, it immediately stirred the sensitive nerves of paper enterprises on environmental issues. Some well-informed paper enterprises had received the news before the release of the "national ten articles" and began to install or transform the desulfurization and denitration facilities in their electric heating projects. The desulfurization and denitration projects of coal-fired boilers of Shandong Chenming paper, Shandong Taiyang paper and Zhejiang Ji'an paper have been put into use, and the desulfurization and denitration projects of coal-fired boilers of Nine Dragons Paper Quanzhou plant and Shandong Huatai Paper are under construction. As far as we know, a considerable number of paper enterprises are seeking cooperation with environmental protection enterprises specializing in providing boiler desulfurization and denitration equipment and technology, including large paper enterprises such as app. At the same time, such enterprises that specialize in providing boiler desulfurization and denitration equipment and technology have smelled the demand of the paper industry for this aspect, and have been rushing around to inquire about the news of the paper mill

at present, the domestic desulfurization and denitration market is not perfect. The industries that adopt flue gas denitration technology earlier include waste incineration industry and power industry. At this stage, the cement industry and paper industry begin to gradually adopt flue gas denitration technology. Enterprises engaged in flue gas denitration industry are mixed, and their strength is uneven. It can be predicted that with the promulgation of the national ten articles, more enterprises will join the flue gas denitration industry. When selecting equipment and technology suppliers for boiler desulfurization and denitration, paper enterprises need to carefully identify and choose powerful enterprises as partners, because flue gas denitration is not as simple as spraying ammonia into the boiler. When choosing denitration equipment, paper enterprises should give more consideration to the operation cost of equipment in the later stage, and get out of the misunderstanding that denitration is a one-off deal

enterprises that have done well in the domestic boiler desulfurization and denitration industry include Shanghai Taixin environmental protection, Chengdu Dongfang kaiteri, Jiangsu Longyuan, China power investment, Qingdao Huatuo, etc. Selective catalytic reduction (SCR rest assured to know our product knowledge) denitration technology is now the most widely used boiler flue gas denitration technology, with high denitration efficiency. In addition, selective non catalytic reduction (SNCR) denitration technology has gradually been mastered and promoted by many excellent enterprises

put forward the goal of air pollution prevention and control action in the national ten articles. After five years of efforts, the overall air quality of the country has been improved, and the heavily polluted weather has been greatly reduced; The air quality in Beijing Tianjin Hebei, Yangtze River Delta, Pearl River Delta and other regions has improved significantly. Strive to use five years or ◆ with the alarm prompt, the image of the alarm device will be solved, and the graphic interpretation of the image will be longer, so as to gradually eliminate the heavily polluted weather, and the air quality of the country will be significantly improved

on September 18, the State Council signed the first certificate of air pollution prevention and control with Beijing, Tianjin, Hebei and surrounding areas and announced it to the public, which is considered to be the most critical step in the implementation of China's air pollution prevention and control policies since the State Council issued the "national ten articles". We hope that through the practical actions of the government, enterprises and all sectors of society, the ten hazes can become history as soon as possible, so that children can laugh heartily, breathe fresh air, and return the blue sky.
