Description
Technical field
The utility model relates to day hot gas boiler energy-saving emission-reduction technical fields, fill more particularly to a kind of combustion gas low nitrogen burning
It sets.
Background technique
With China's industrialization, the deep propulsion of urbanization, energy consumption continues to increase, and it is tight to reduce atmosphere pollution situation
High, atmospheric environment problem becomes increasingly conspicuous.2015 since winter has set in Beijing frequently meet with the harassment of mist thunderbolt weather, and more drill more
It is strong.The appearance of mist thunderbolt weather, not only affects our life, but also has further influenced our health.
Occur to reduce mist thunderbolt weather, further environmental quality is promoted to improve, Beijing starts in full urban area
Carry out pressure and subtracts coal-fired, air cleaner action plan." Beijing 2013-2017 clean air action of Beijing Municipal Government's publication
Plan ", it is distinctly claimed " constantly promoting the transformation of gas fired-boiler low-NO_x combustion technology, implement nitrogen oxides improvement ".And Beijing
Environmental Protection Agency has issued " emission standard of air pollutants for boilers " (DB11/139-2015) on May 13rd, 2015, it is desirable that from
From on April 1st, 2017, it is being less than 80mg/m with gas fired-boiler emission limits of nitrogen oxides3;Newly-built gas fired-boiler nitrogen oxides
