5 Mw Water Gas Boiler In France

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.

Furnace pulverized coal fired boiler is smaller than you: Today saw a piece of content, said: with the same capacity, oil-fired boiler furnace is smaller than pulverized coal. why? The following reasons: the size of the furnace volume, in the boiler capacity is determined, depending on the size of the volume of heat load. Volumetric heat load size is mainly determined by the type of fuel. After the fuel into the furnace, it will take some time to burn. Typically all the required fuel burn before leaving the furnace, the pulverized coal burnout is obviously longer than oil, i.e. coal flame longer than oil. To ensure long-term safe operation of the boiler, not only to prevent the boiler slag, and flue gas at the furnace exit is low to make the temperature at the start of the deformation ratio of ash flue gas temperature 50 ~ 100 ℃, at the outlet of the furnace and to prevent subsequent convection slagging heating surface. In many coal ash content, coal-fired furnace to control the furnace exit gas temperature typically of 1050 ~ 1100 ℃. The fuel oil furnace because very little ash, furnace slag is not dangerous, do not consider the problem of slagging furnace slag discharge outlet pipe, so the furnace exit gas temperature can be higher. For the above two reasons, the volume of the thermal load is higher than Pulverized fuel boiler. Pulverized volumetric heat load is about 145 ~ 185kw / m3, and the volumetric fuel burner heat load of up to 255 ~ 350kw / m3, so the same volume of the furnace fuel burner furnace capacity is relatively small pulverized coal fired.

The reason for the low nitrogen boiler What are reasons for the low nitrogen boiler has what? Coal is a major component of China's energy, coal consumption accounts for about 76% of primary energy consumption. With the rapid economic development and the rapid increase in coal consumption, coal caused by air pollution is getting worse, especially coal-fired flue gas released nitrogen oxides (NOx) are major pollutants of air pollution one. Nitric nitrogen oxides can damage the ozone layer, changing the intensity of UV irradiated to the ground; also cause changes in the ozone layer climate change, which will affect the entire environment: air, nitrogen nitric oxide or an important source of acid rain, acid influence. In the environment it is widely known that the soil and water acidification, growth of crops; also demonstrated a number of human diseases are also generated directly related to the nitrogen oxide in the air of nitric oxide. In the fuel combustion process, NOx in the atmosphere dissolved in water will form acid rain, caused widespread damage to the environment caused by corrosion, damage and other open-air heritage buildings and industrial equipment huge economic losses. Damage to the plant resulted in the death of forests; fish and lakes death; destruction of crops and soil composition of the production loss, and even death; groundwater drinking is harmful to humans. Nitrogen oxides are also directly endanger human health. The higher the concentration of nitrogen oxides, the stronger the toxicity. Because it is easily combined with animal hemoglobin in the blood, causing blood to oxygen, causing paralysis of the central nervous system. When NOx is present ultraviolet radiation of the sun, automobile exhaust hydrocarbons, light blue form toxic compounds. Byproducts are City City primary air containing pollutants such as hydrocarbons and nitrogen oxides, it refers to the product of the solar radiation to produce specific chemical reaction and the resulting mixture mist. It makes the eyes, nose, lung and other organ damage, red eye, tears and other symptoms. Long-term chronic hazards can cause pulmonary dysfunction, bronchitis, and even the development of cancer. Severe cases can cause severe chest pain, nausea and vomiting, hand-foot discomfort, blood pressure, coma and even death. In recent years, large areas of severely affected by fog and haze, the lives of the people caused great pain. Many people mistakenly believe that only respirable particulate matter is the major cause of haze. In fact, another reason: nitrogen oxides can not be ignored.

Note that the operation of the gas boiler gas boiler matters Introduction LF products include gas-fired boiler gas hot 5 mw water boiler in france, gas hot water boiler and gas steam boilers, gas hot water boiler which is also called the gas hot water boiler and gas hot water boiler. Gas boiler, by definition, refers to a gas boiler fuel. Gas-fired boiler, oil-fired boiler, electric boiler is the most economical boiler, so most people choose a gas boiler as steam, heating, bath boiler equipment. Precautions gas boiler valve operation of the gas boiler is a device commonly used in power plants. Typically, the handle and the hand wheel, thorium designated rotation direction closing, counterclockwise rotation is designated as the opening direction. But some valves should check before running the opening and closing flag. The following is a gas boiler manufacturers ajar gas boiler in operation, the valve should open quickly points to note: gas boiler slowly open the valve is first opened, and then open the quick opening valve, the preheating duct, then fully open. In order to better sewage, can be repeatedly turned on and off quickly open the valve. After discharge, to open the valve to close quickly, and then slowly open the valve to close, and finally quick opening valve is opened, the washing water between the two valves.
