Introduction of qualification standards for low-nitrogen transformation
The reformed gas boiler should meet the requirements of safety performance, low nitrogen emission and energy efficiency under the condition of full combustion. The boiler can operate safely and stably under the condition of full combustion. The NOx emission concentration is stable below 50mg/m3, and other pollutants meet the requirements of GB13223 and GB13271. In addition to environmental protection indicators, the CO emission concentration should be lower than 95mg/m3. Newly built or completely replaced boilers are encouraged to stabilize NOx emission concentration below 30mg/m3.
The thermal efficiency of the boiler after low-nitrogen transformation conforms to the regulations of DB33/800 "Boiler Operation Energy Efficiency Limit and Monitoring Technical Requirements", and the energy test method is as follows: Industrial boilers are executed according to GB/T 10180-2017 "Industrial Boilers Thermal Performance Test Rules", and power station boilers are executed according to GB/T 10184-2015 "Power Station Boilers Performance Test Rules".
Low nitrogen modification inspection and detection
The inspection and testing of low nitrogen reformation should meet the requirements of laws, standards and relevant regulations. The following points should be paid attention to in the transformation process:
