This technique is performed by coal-fired boilers, pulverized coal amount to be injected into the furnace in place, so that the combustion grate base layer, an appropriate amount of the suspension increases combustion energy can be obtained a certain rate. As for boiler fuel, gas type, you can replace the old with the new energy-saving burner, behind the burner to be transformed.
How to put ordinary gas fire tube boiler high quality boiler emissions become low nitrogen boiler is an important cause of air pollution in order to reduce pollution of the boiler, in the country minus the cancellation of coal coal have done a lot of work, which significantly reduces the solid boiler soot emissions and sulfur dioxide emissions of polluting gases. But only coal-fired boilers will be replaced by gas-fired boilers, boiler did not reduce emissions of nitrogen oxides, so the boiler with a new task becomes low nitrogen boiler boiler also became current. In the end what is low nitrogen boiler? In many areas, there is no mandatory use of low nitrogen boiler regulations, and in Beijing, mandatory use of low nitrogen requirements of the boiler has been formally introduced in April 1 this year, the existing boiler will perform the following 80mg standard, the new boiler will perform the following criteria 30mg, 80mg and standard criteria will gradually be replaced by 30mg of the boiler, and therefore in Beijing, boiler NOx emissions less than 30mg in order to become a low-nitrogen boiler. In Henan, the new gas-fired boiler will also perform the following criteria 30mg of nitrogen oxides, we can safely predict that the future low nitrogen boiler will be large-scale promotion. At this stage, a lot of nitrogen oxide emissions from gas-fired boiler in 150mg or less, which is far unable to meet the standard low-nitrogen boiler. Ordinary means into a low nitrogen gas boiler with a boiler or low nitrogen transformation replace the original boiler is condensed into nitrogen oxides emissions below 30mg (formula) boiler. Nitrogen mainly low boiler transformation replace Burner, mainly in the following ways: 1, flue gas recirculation transformation (Ultra Low NOx) is the use of combustion air head, the part of the combustion fumes sucked back into burner, and combustion air mixture. Since the flue gas recirculation, the combustion fumes a large heat capacity, the combustion temperature is lowered, the NOx reduction. Another recirculation burner itself is directly recycled into the part of the fumes inside the burner and to the combustion process, the burner has such a suppression effect of nitric oxide and the double energy. 2, the premix burner (combustion surface) technology premix gas burner, the gas and air are thoroughly pre-mixed prior to entering the combustion chamber, so that more complete combustion, improve the combustion efficiency and reduce harmful emissions, but also can reduce the space requirements of the combustion chamber, is currently the most advanced of a gas combustion technology. Due to the low NOx combustion boiler renovation and diverse, sophisticated technology, in order to ensure the smooth implementation of the transformation, effectively preventing security risks, prevent accidents, analysis and appraisal by experts, comprehensive security, environmental factors, Beijing and the Beijing Municipal Environmental Quality and Technical Supervision protection Bureau jointly issued a notice :( a) for 7.0mw (evaporation 10t / h) or more in the boiler is not recommended transformation of the way premixed combustion. (B) to the central back-fired boilers, the transformation is not recommended way to replace the burner. (C) For boilers, does not recommend the use of direct transformation of the way the transformation of the burner. Therefore, a low nitrogen transformation process boiler, more often, is a direct replacement for the original gas boiler low nitrogen boiler.

With the development of economy and social progress as well as the improvement of people's awareness of environmental protection, coal-fired fire tube boiler high qualitys are gradually out of sight because of serious pollution. Instead, they are replaced by new types of environmental protection digital boilers, such as electric heating boilers and oil-fired boilers. Gas-fired boilers, such as gas-fired boilers, are the most expensive to operate, gas-fired boilers need to be opened with gas pipelines, then, if there is no natural gas pipeline, and hope that the operation cost of the boiler is low, only the choice of fuel-fired boilers. Oil-fired boiler is heated by burners, fuel atomization effect is good, fuel combustion is full, chimney can not see black smoke, so fuel-fired boiler green environmental protection, efficient and energy-saving.
