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 heating steam fire tube boilers 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.
Contrast gas steam heating steam fire tube boiler and gas steam boiler? Which is more cost-effective? There are new users will ask gas steam boiler and gas steam boiler which is more cost-effective in a number of economic operation? Believed to be ready to buy a steam boiler of every business relationship or personally, with you today, I will work together to analyze these two boilers in operating costs to do a comparison. First, the first point to analyze procurement costs: Because gas steam boiler in the annex above techniques and configurations to be clear leadership and gas steam boiler, gas steam boiler supporting a dedicated burner, a burner just put the cost price opened, so that the same tonnage of steam boilers, steam boilers high gas prices than gas steam boiler more. The second point to analyze construction costs: The costs mainly from the boiler room, boiler tubes of steam investment funds. In which the gas steam boiler because more appropriate auxiliary equipment, so in the boiler room construction funds to be more. There is a gas steam boiler automatic control operation, and automatic alarm and automatic protection function. Connected to the gas pipeline, the burner will automatically supply costs can effectively save staff. Gas-fired steam boiler because of the need of coal on the program, so in terms of personnel expenses wage will be larger. The third point to analyze the environmental cost: major review means that now more stringent gas steam boiler. The gas steam boiler due to the operation of the economy, environmental protection and energy saving, as well as government policy to encourage more and more widely used. The fourth point to analyze fuel costs: gas steam boiler will be much higher than the steam boilers in gas fuels. After analyzing the above four points of view than the gas steam boiler Gas steam boiler in order to save more on operating costs, but gas steam boiler environmental protection, now increased pollution than gas steam boiler in environmental protection in recent years so the state more stringent control of environmental pollution, so in accordance with the requirements of environmental protection point of view has an advantage gas steam boiler.

How to maintain the heating steam fire tube boiler shutdown? After boiler shutdown cooling, heating surface must be thoroughly cleaned of fouling and ash grate the upper, the lower portion of the furnace. Then to maintain a certain degree of natural ventilation flue. In general, in order desiccant moisture should be placed in the furnace, flue. The quicklime as a drying agent, within the furnace or flue gas per cubic meter should be placed generally about 3kg. After placing all the ventilation should be tightly closed doors. After the change of lime powder to be replaced. Low-lying position as boiler room, ground during shutdown severe flood tide, often approach should be used and placed a small fire to dry desiccant combination. How to care? If the boiler shutdown a long time, the boiler shutdown after complete removal of soot coated with an anti-corrosion red lead paint in oil or other metal surface furnace. As internal corrosion Maintenance shutdown of the boiler body, under normal circumstances, can be used wet shutdown maintenance is not more than one month, one month electrically operated steam boiler should be taken to dry more maintenance. To note the following problems when a dry maintenance: desiccant boiler not in direct contact with the metal surface, may be mounted in a container such as the iron plate after the desiccant is placed, and a hole for shutting the other hand hole cover.
