Recently, the letters and the ecological environment unit, the letter of "boiler air pollutant emission standards" in the "gas boiler exhaust pipe predetermined height of not less than 8 meters, within 200 meters from the building around the radius of the new boiler room chimney when was the tallest building in which the chimney should be higher than 3 meters "requirement questions.
First, the new urban gas boiler chimney should be performed outside the specified height is 3 meters above the surrounding buildings (there are many communities within 200 meters around the building height higher)?
Second, on the 20t / h steam boiler and above, and more than 14MW hot water boiler to be installed pollution-line monitoring equipment, this means that a single 14MW boiler or boiler means the total audience of 14MW?
Third, for example, I have more than 2MW heating station natural gas hot water boiler 7 units, exhaust gas through the two exhaust pipe emissions, the need to install pollution monitoring equipment?
A "boiler air pollutant emission standards" (GB13271-2014) states that "fuel, gas boiler stack height of not less than 8 m, particularly boiler stack height is determined by the EIA document approved. Chimney around the new boiler room when there is a building within a radius of 200 meters, the tallest building in which the chimney should be higher than 3 meters. when there is a building within 200 meters around the new boiler house chimney radius, "according to the provisions in the new urban area gas boiler should be implemented", the chimney should be higher than the provisions of the tallest buildings in more than 3 meters, "the.
Two, 20t / h steam boiler and above, 14MW and more hot water boiler must be installed in the line monitoring apparatus contaminants "14MW and more hot water boiler" means a single boiler.
Third, on the "exhaust gas through the two exhaust pipe emissions, the need to install pollution monitoring equipment" problem, according to "People's Republic of China Air Pollution Prevention Law" Article 24 "key sewage units should be installed, using air pollutant emissions automatic monitoring equipment, and environmental protection departments to monitor network devices, monitoring equipment to ensure the normal operation of public and emissions information in accordance with law. "provisions, as well as the" State Council on the issuance of three-year action plan to win the blue sky to defend the notice "(Guo Fa [2018 ] No. 22) "outfall height of over 45 meters of elevated source, as well as petrochemicals, chemicals, packaging, printing, painting and other VOCs emissions from industrial sources focus, the focus of sewage into the Directory of key areas should be basically completed by the end of 2019 to install flue gas automatic monitoring facilities, the country should be basically completed by the end of 2020 the automatic installation of flue gas monitoring facilities. "requirements, if the exhaust pipe where the company was listed as key units of sewage, flue gas monitoring facilities should be installed automatically, otherwise, no installation.
Green oil-fired boilers, oil-fired boiler comprising fuel energy efficient water boilers, hot water boiler fuel, the fuel heating boiler, oil bath boiler, and steam boiler fuel, gas oil refers to the boiler fuel (such as diesel, kerosene), heavy oil, residual or oil-fired boiler. Oil-fired boiler and gas boiler, electric heating boiler compared to oil-fired boiler to run than electric heating boiler economic, easy to use than gas-fired boiler. With economic development and social progress and improve people's awareness of environmental protection, gas boilers due to serious pollution, moving away from sight, replaced by a new environmentally friendly digital boiler, such as electric heating boiler, oil boiler, gas boiler, electric heating The most expensive boiler, gas boiler need to open a gas pipeline, then, if there is no gas pipeline, and hope boiler low operating costs, only select oil-fired boiler. Oil-fired boiler is heated by a burner, fuel atomization effect, fuel combustion, can not see the chimney smoke, so the green fuel boilers, energy efficient. After spraying fuel through the burner into the furnace in the atomized droplets, and easily mixed with air and the rapid combustion heat flash. Compared with gas boiler parameters and the same capacity, the heat intensity of furnace volume may be increased about twice. But to reduce the thermal load of the burner zone, in order to avoid overtemperature waterwall tubes in this area, so the furnace volume is only reduced by about 1/3. Because very little fuel in the ash, without slagging in the convection heating surface, it allows the furnace exit gas temperatures as high as 1300 ~ 1350 ℃, and narrow a pitch between the convection heating surface to increase the flue gas velocity, thereby increasing the heat transfer coefficient of the heating surface, the heating area savings and steel. To prevent the economizer and the air preheater product grease spontaneous combustion of carbon black raw, typically on the parts to be installed to maintain the steam sootblowers clean the heating surfaces. Meanwhile, since the fuel is not cinder junction, so the membrane wall can be made slightly positive pressure (500 - 1000 Nm / m) boiler. It omitted draft fan, blower can only exhaust fumes out of the furnace. If the overall boiler housing made of thick steel plate, it can also be made pressure (0.3 to 0.6 MPa) boiler, the boiler can more compact overall structure, used for gas - boiler manufacturer steam generator sterilizer in a combined cycle.
Steam boiler heat loss is what causes? Steam boiler heat loss caused to the user a lot of burden, whether it is hot steam boiler what is causing the loss of it? To analyze together with you today. Specific causes heat loss of the steam boiler at several: 1: heat loss of exhaust energy: smoke exhaust gas boiler comprises means losses are not completely absorbed by the steam heat loss. How caused? Short distance high temperature flue gas fan suction force is too high, the high temperature flue gas immediately excluded from the boiler; a small heating area, high temperature flue gas boiler can not be sufficiently absorbed. 2: the fuel gas does not completely heat loss: the combustible gas discharged from the flue gas generated in a boiler, the fuel in the combustible gas or gaseous fuel combustion process itself does not contain all of the incomplete combustion releases heat losses arising. As the incomplete combustion of carbon monoxide and carbon dioxide containing off-gas produced by combustion compared to the complete, only a quarter of the amount of heat released. 3: Solid incomplete combustion heat loss: refers to the solid fuel combustion process as a fuel grate down the drain does not release the heat of the flammable substance and ash contained in the combustion of the fuel can not completely burned released heat loss caused. 4: Loss steam boiler Grate: refers to the internal heat loss of the absorbent. 5: high temperature heat loss: Indicates high water temperature and hot water temperature, heat loss. 6: heat losses within the boiler manufacturer steam generator sterilizer tube due to furring bilingual.
How Wanning miniaturization steam boiler to buy a lot of companies actually steam boiler supply and demand on the number of small lot, so this kind of miniaturization, also known as steam boiler boiler manufacturer steam generator sterilizer, the burner according to the water temperature reaches 100 degrees, it will rapid formation of steam, thereby leading to the manufacturing needs of the user. This is what we often want to explore downsizing steam boiler. Thus how do we buy steam boilers, in fact, we are generally able to purchase fuel from their own advantages and steam boilers, and some people need to use their own power, we buy that is electrically powered steam boilers can greatly reduce own costs. If the size is very large steam boilers, auxiliary gas pipeline through nor can purchase a biomass steam boiler, can reduce fuel costs, according to their manufacturing biomass, can quickly reach the combustion of fuel. If the steam supply and demand value is very small, you can buy often said steam generator to reach a big problem with a small cost!
