A: GB13271-91 "Boiler Air Pollutants Emission Standards" taking into account the actual time, no before August 1, 1992, installation (including project not already installed) the development of boiler SO2 emission concentration limits. In order to control this part of the boiler emissions of SO2 pollution, provinces, autonomous regions may promulgate local environmental standards, proposed SO2 emission limits may be approved in accordance with the spirit of "two control zones" of the State Council, made the total SO2 emissions control program. The remaining question, along with the revised standard will be further addressed.
Zhengzhou Sunrise Optoelectronics Technology Co., Ltd. by the Dongxu Group, Henan Province, the state-owned asset management companies and Zhengzhou Investment Holdings Limited jointly made, mainly engaged in flat panel display and solar industry design materials, manufacturing and sales operations. Sunrise Optoelectronics project has been put into a production line, the second phase will continue the expansion, three new production lines to meet the production needs of Project Phase II, Sunrise Optoelectronics urgent need to increase new boiler equipment. After investigation and screening of a number of boiler brands, determined to cooperate with the fast boiler, steam signed a 10-ton integrated condensing gas steam boiler (WNS10-1.25-Y.Q).
Gas boiler needs to be done a number of environmental measures which coal-fired boiler needs to be done desulfurization and denitrification, gas boiler it? Is not just do the dishes soft water? Gas boiler attributable to the clean energy, no need to smoke other dishes. Treatment on water, do not know what you say is which side? Gas boiler feedwater sure to go through the soft water, avoid gas-fired boiler scale formation. If the water is discharged slag, simply lowering the temperature, precipitation was just fine direct emissions. As a result, gas boiler without environmental protection measures.
Combined with China's current situation, the provinces and cities have environmental requirements. General requirements for a gas-fired boiler increases: low nitrogen. Condensing technology now used in the fast side is one of the primary techniques to reduce nitrogen oxides (abbreviated NOx) in. If NOx emissions do not meet state regulations, it is absolutely not allowed to be used, even after running for some time, EPA will be ordered for low-nitrogen transformation or elimination process.
