When the external load variation, the temperature in the boiler and metal working fluid, the heat and other changes have occurred. When the load increases as combustion is not timely adjusted so that the steam pressure drops, the corresponding saturation temperature drops, a corresponding reduction in boiler water liquid heat, and the heat storage pot of water at this time in the metal release, will become part of vaporized boiler water itself steam. These generate additional evaporation, can play a role in mitigation of the vapor pressure decreased.
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 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.
To improve the thermal efficiency of the boiler method? The thermal efficiency of the boiler is directly related to the economic interests of the boiler's, so the design efficiency of the boiler is definitely the most concerned about the boiler's index, which determines the cost of running the boiler, in general, the higher the efficiency of the boiler, the fuel lower consumption, will directly reduce operating costs of the boiler.
Whether it is for what equipment, corrosion will have a bad effect, gas boiler as well. Avoid gas-fired boiler corrosion, will adversely affect all strangled in the cradle, to make boilers in long-term stable operation.
