5. The local site environment protection standard

For natural gas fired boiler, if it has requirements about NOx emission , for biomass boiler , the particular emission is very important , if local is strict with the dust emission ,as 30mg/nm3 ,maybe the boiler system will need bag filter , the price will enlarge .

Biomass steam food processing pressure fire tube boiler price to produce one ton of biomass steam consumption is about 180kg.

Third, the natural gas steam boiler

Coal occupies a large part of our energy economy, but coal brought sulfides, carbides, dust, ash and other harmful substances are also severely affected the people's living environment and ecological environment. At this stage, China's major provinces and cities in the related industries of coal fired food processing pressure fire tube boiler prices released specific remediation programs. By treatment of coal-fired boilers, can effectively promote air pollution control and bulk coal governance work.

Hebei Province was polluted our province, many kinds of heavy industries, heavily polluting enterprises, geographic and congenital conditions are not conducive to the spread of pollutants, and other factors lead to high emissions of air pollutants in Hebei Province.

In recent years, Hebei Province, through the management of coal-fired boilers, the "coal to gas", "coal to electricity", and many other measures to enhance the governance of the ecological environment, improve people's happiness index of blue sky. According to statistics, as of the end of October this year, Hebei province has eliminated emissions of less than 35 steam tons / hour (including 35 steam tons / hour) coal-fired boiler units 6492, a total of 12744 tons of steam, respectively, to complete the annual task of developing 96% and 95%; for the emissions amounted to more than 35 steam tons / hour of coal-fired boilers transformation process, has been the transformation of 158 units totaling 12185 tons of steam to complete the annual task of developing 70% and 95%, respectively.

Future, Hebei Province will continue to carry out renovation work on coal-fired boiler more specific details of. Through the establishment of this ledger management mode, regularly check and keep track of coal-fired boilers governance; development of special treatment programs to strengthen the "coal to gas", "coal to electricity" transformation content; relevant policies to achieve strong support and assistance encourage.

This year, the environmental protection departments in Hebei organize multiple ecological environment and comprehensive management of air pollution inspection work, as one of the key phase out coal-fired boiler inspection work has been widely attention. For no control measures, emissions exceeding the bulk coal fired boiler, remediation process according to the law or banned.

Hebei Province will further improve control efforts obsolete coal-fired boilers. The next stage will be formulated "boiler emissions of air pollutants, Hebei Province, local standards," for the local coal-fired boilers do not meet the standards of remediation and prevention measures to strengthen inspections of coal-fired boilers have been eliminated to prevent burning complex phenomenon occur.

Maintaining the environment and sustainable development is an important prerequisite for China's economic and social development. The provinces and cities in response to national policy development environment, make specific control measures, Hebei provinces and cities will also combine their own situation, the air pollution control work carried out in the end.

This standard at age requirement food processing pressure fire tube boiler price flue soot, sulfur dioxide and nitrogen oxides emission concentration maximum permissible emission limits, and the blackness. This standard applies to coal-fired capacity and intended use of the fuel and emissions of air pollutants manage outside gas boiler boiler, and construction project environment (65t / h) In addition to power generation boilers and pulverized coal is greater than a single output 45.5MW impact assessment, design, final acceptance and after the completion of the sewage management.
