Fully Automatic 20t coal fired boiler Commercial Cambodia

Low NOx emission combustion fully automatic 20t coal fired boiler commercial cambodia technology a boiler combustion boiler hypoxic hypoxia NOX emissions from combustion is the easiest way to control. And a combustion burner system does not need to make any changes, only control air flow into the furnace in operation, pulverized coal combustion process as close to the theoretical combustion air amount. Low oxygen combustion scheme can reduce NOX emissions by 20% to 30%. The program practical application subject to conditions. Low oxygen furnace, will increase the amount of unburned carbon, and more difficult for the flame of burning coal more obvious; Further, the CO concentration is also increased so that smoke, which will cause decreased boiler efficiency. Another problem is that for certain boilers, hypoxia causes the main combustion steam or reheat steam temperature is low. The burning coal to immediately, boiler efficiency and reduce the magnitude of steam temperature and other properties to determine the appropriate control value of flue gas oxygen furnace outlet (at or economizer) the specific embodiments. Second, air staged combustion technique combustion air into a plurality of strands, it is gradually mixed and pulverized coal combustion, so you can see the local area to reduce the air-fuel ratio, and the thermal decomposition of coal in the ignition phase, due to hypoxia, and thus the nitrogen oxide generation is suppressed. Air classification may be implemented within the combustor, the boiler can be completed within. 85% of the amount of air required for complete combustion is introduced to the main burner, the main burner combustion zone is insufficient oxygen for the fuel-rich conditions. Due to insufficient amount of oxygen, the flame temperature is low, the amount of nitrogen oxides to less generation of fuel nitrogen intermediates (e.g., NCH, NH3, etc.) will therefore not be oxidized NOX. Meanwhile, it has been possible to further reducing NOX generated in a reducing atmosphere to molecular nitrogen (N2 of), as a result reduces NOX emissions. An upper portion of the top floor is provided Ge overfire air (of OFA) spout into the furnace through which about 15% of the rest of the air, to avoid the high temperature flame zone, it is also possible to burn unburned carbon particles, to complete the combustion process.

To implement the "Blue Sky Hohhot to win the Battle of three-year action plan," Hohhot ecological Environment Agency and vigorously promote the city's coal-fired fully automatic 20t coal fired boiler commercial cambodias mentioned standard transformation and treatment, formulated the "65 steam tons / hour or more coal-fired boiler and governance to promote the program." clearly this year will focus on the 65 steam tons / hour or more coal-fired boilers and in particular the implementation of ultra low emission limit values ​​renovation work to further reduce emissions from coal-fired boiler pollution, improve the city's quality of atmospheric environment.

Program clearly states that the city has 58 coal-fired boilers will be completed before the end of the transformation, in which five large-scale district heating enterprises 65 steam tons / hour and over the implementation of ultra-low emission coal-fired boilers transformation,

16 65 steam tons / hour or more coal-fired hot water boiler to complete the transformation of governance. To ensure the smooth implementation of the mentioned standard treatment project, municipal environment bureau called on all localities in strict accordance with the "grid" management approach, down to every level will be the task of transformation, to the people, the letter coal-fired boiler to complete the task, each Related enterprises should play the main role, strict compliance with environmental laws and regulations and energy-saving standards, to complete the task on time.

To step up supervision and municipal environment bureau set up a special steering committee to implement the "Fortnight scheduling system", the city's coal-fired boilers governance supervision, the work of the task is not implemented, governance behind schedule, promote ineffective areas and enterprises to implement early warning and interviews, due to the unfinished task of accountability.

DZL series bagasses steam fully automatic 20t coal fired boiler commercial cambodia in distillery, its capacity is from 2 to 10 ton. This boiler can be used in smaller distillery. DZL series boiler can burn coal fuel, biomass fuel, and mixed fuels, so does SZL series and DHL series. DZL series chain grate boiler, its features like Inverted "α" arch furnace technology, combustion efficiency improved. It is a kind of fire tube boiler, automatic operation system, packaged boiler.

There are a number of options available for the direct co-firing of solid biomass materials in large pulverised coal fired fully automatic 20t coal fired boiler commercial cambodias, including: pre-mixing the biomass with the coal, added dedicated biomass mills, 100% conversion of one existing mill, parallel boilers, and gasification.
