April 4, 2019 morning, Xi'an Beilin haze iron-fisted rule to organize the use of gas-fired high efficiency laboratory boiler unit of area businesses, held a 2019 low nitrogen gas boiler renovation work Publicizing.
The meeting mainly to accelerate the transformation of low nitrogen gas boiler Beilin, the ecological environment Beilin Branch Office investigator, neighborhood offices iron-fisted rule haze Director; area involving boiler 2019 user units, boiler enterprises, related to the monitoring unit responsible comrades total of more than 180 participants. Ecological Environment Agency Beilin Branch Comrade security level currently in Xi'an ambient air quality situation, problems and countermeasures were presented. Ecological Environment Agency celebration party strongman rule Beilin Branch Office Director haze on the transformation of relevant documents and carry out propaganda premium policy interpretation. 2018 transformation of the user units China Qiyuan Engineering Design & Research Institute Co., Comrade Yang Ann introduced to transform the experience of last year. Finally, the ecological environment Beilin Branch Bureau researcher Liu made a concluding statement:
2. Energy saving and environmental protection
the boiler uses the advanced combustion technology, sets up large area combustion chamber, the rotational flow secondary air distribution, makes the fuel burning more fully.
Premix condensing gas high efficiency laboratory boiler is introduced a new fast boiler gas boiler, fuel and air before combustion rational allocation, to achieve full combustion of the fuel to optimize combustion environment, while reducing the nitrogen oxide emissions, but also improve the boiler thermal efficiency, reducing fuel consumption. Compared with ordinary gas boiler, the biggest change is that: improved thermal efficiency, reduced pollutant emissions such as nitrogen oxides.
Factors high efficiency laboratory boiler flue gas dew point: boiler flue gas water vapor begins to condense is called the dew point temperature, dew point level on many factors. The water vapor content of the flue gas water vapor partial pressure multi i.e. high, the dew point. However, the partial pressure of water vapor dew point thermodynamic decision is low, e.g., oil-fired boiler in general, the flue gas water vapor partial pressure of about 0.08 to 0.14 atmospheres absolute, and the corresponding thermodynamic dew point of 41 ~ 52 ℃.
