Gas boiler cook stove Note: As the boiler equipment kinetic energy sources in the manufacturing, transportation, installation and maintenance process will bring oil and other impurities, persist in the boiler, it will not only clog water pipes, deteriorating the quality of steam, but also will reduce the heat transfer effect, the heating surface prone to overheating cause burn. Therefore, for removing impurities boiling out this step, the stable operation of the boiler is an integral part.
How to identify whether the toxic chemical plant boiler emission sources on how to identify whether the toxic chemical plant boiler emission sources? Now, the chemical inside the boiler or the production of major productivity. But there is a time of some chemical plants for production of boilers, flue gas emissions place are smoke smoke. Which is the most common white smoke tobacco, and there are a lot of people will find that the more obvious the more cold weather white smoke, which is why in the end, saw the boiler flue gas chemical plant will be white coming out. In fact, most white column of smoke, especially in cold weather to see, and water vapor is condensed water droplets nothing. Boiler feed water tank is equipped with a chimney, only water vapor and air emissions. Water is one of the important by-product of combustion, so the chimney of coal, oil and natural gas boilers have water vapor. To reach reduce dust pollution emission regulations, companies will discharge terminal apparatus water filtration apparatus into the exhaust gas boiler water filtration, all the inside of the dust filtered off, and then discharged to the atmosphere. Hyperthermia with dust filter, the exhaust gas is also absorbed by water to form water vapor is discharged from the chimney, the cold white smoke that we see a. In chemical plants, always able to see a kind of braving the plume of flame, burning in it day and night, in fact, this is not a column of smoke, its name is called safe torch. Chemical plant in the production process, many of flammable and explosive gases can occur, many of which are harmful. They are large heavy than air, if released into the atmosphere, by extension, be deposited on the ground and reaches very high concentrations, which will form a serious environmental pollution and damage to human health, should encounter fire, the fire will be formed, and the blasting . In order to prevent the onset of these risks, people will set them up and burn to prevent future trouble. There is also a mistaken chimney built, in fact, they are cooling towers, water vapor is discharged from the sterilization algae and some trace of drugs. Cooling towers is cold and hot water and steam generation using the air flow after the touch, the steam reaches the transpiration transpiration remove heat dissipation, convective heat transfer principle of thermal radiation and dissipate heat like occurs in industrial refrigeration and air conditioning, or to decrease the water temperature transpiration cooling means to ensure the normal operation of the system, it is above the water vapor.
National response to control air pollution and maintain policies favorable ecological environment; effective control of thermal power, steel and other key industries, the total amount of atmospheric emissions of major pollutants, Ningxia implementation of thermal power, steel and other industries, especially air emission limits for pollutants in the metropolitan area of Yinchuan.
In particular emission limits refers to higher standards than the national emission of pollutants, more stringent emission requirements; implementation of special emission limits, implementation of key industries mentioned standard transformation is one important way to reduce pollutant emissions. Yinchuan City metropolitan area including Yinchuan, Shizuishan City, Wuzhong City Litong District, Qingtongxia City Administrative Region and Ning Dong Energy and Chemical Base (core area). Perform particularly air pollutants emission limits in all of these areas of thermal power, iron and steel, cement, petrochemical, non-ferrous metals, chemical industry, coal-fired boilers and sulfur dioxide, nitrogen oxides, particulate matter.
Since the execution time is tentatively scheduled for January 1, 2019, for the present, China has not yet specified air pollutants emission limits in particular industry, to be the relevant standards or modified, re-implemented.
For enterprises, especially not achieve emission limits of air pollutants, the government has formulated a series of remediation measures, the relevant enterprises to effectively assume responsibility for the theme of pollution control, ensure the completion of the task within the stipulated time. For within the specified time still can not meet the requirements of enterprise and equipment, the relevant departments will be severely punished according to law.
The essay serve a documented basis for joint project of erection and operation of biomass residue firing CHP (Combined Heat and Power) unit. 58 tons/hour of steam at 12 barg are generated in few heavy oil firing boilers and consumed in production process. The basic assumptions are that saw dust or/and wooden chips with LHV (Low Heating Value) 18,000 kJ/kg will be fired in a fluidized bed boiler producing about 30 ton/hour steam (about a half of needed process steam). The steam flow, passing through a back pressure turbine, will generate electricity corresponding to difference of enthalpies of fresh steam generated in the boiler and of one needed for process. From the turbine outlet the steam will be used, as today, for the technological process of the factory.
