low nitrogen gas steam boiler

Short Description:

How to distinguish whether the steam generator is a low nitrogen steam generator
The steam generator is an environmentally friendly product that does not discharge waste gas, waste residue and wastewater during operation, and is also called an environmentally friendly boiler. Even so, nitrogen oxides will still be emitted during the operation of large gas-fired steam generators. In order to minimize industrial pollution, the state has promulgated strict nitrogen oxide emission indicators and called on all sectors of society to replace environmentally friendly boilers.
On the other hand, strict environmental protection policies have also encouraged steam generator manufacturers to continuously innovate in technology. Traditional coal boilers have gradually withdrawn from the historical stage. New electric heating steam generators, nitrogen low steam generators, and ultra-low nitrogen steam generators, Become the main force in the steam generator industry.
Low-nitrogen combustion steam generators refer to steam generators with low NOx emissions during fuel combustion. The NOx emission of the traditional natural gas steam generator is about 120~150mg/m3, while the normal NOx emission of the low nitrogen steam generator is about 30~80 mg/m2. Those with NOx emissions below 30 mg/m3 are usually called ultra-low nitrogen steam generators.

In fact, boiler low-nitrogen transformation is flue gas recirculation technology, which is a technology to reduce nitrogen oxides by reintroducing part of the boiler exhaust smoke into the furnace and mixing it with natural gas and air for combustion. Using the flue gas recirculation technology, the combustion temperature in the core area of the boiler is reduced, and the excess air coefficient remains unchanged. The formation of nitrogen oxides is suppressed without reducing the efficiency of the boiler, and the purpose of reducing nitrogen oxide emissions is achieved.
In order to test whether the nitrogen oxide emission of low-nitrogen steam generators can meet the emission standards, we have carried out emission monitoring on low-nitrogen steam generators on the market, and found that many manufacturers use the slogan of low-nitrogen steam generators to cheat by low prices Consumers are actually selling ordinary steam equipment.
It is understood that for regular low-nitrogen steam generator manufacturers, the burners are imported from abroad, and the cost of a single burner is tens of thousands of yuan. Consumers are reminded not to be tempted by low prices when purchasing! In addition, check the nitrogen oxides emissions data.
