About Henan low nitrogen gas coal all premixed condensing boiler rank and the transformation of Henan low nitrogen gas boiler is upgraded on the basis of common furnace on it than the ordinary boiler biggest advantage is that the emission of nitrogen oxides. Henan low nitrogen gas boiler is divided into two: one is nitrogen oxide emissions below 80 mg; the other is a nitrogen oxide emissions below 30 mg. Of course, if you want to achieve low nitrogen emissions, it must be met is to use low-nitrogen burners. From the development trend, Henan low nitrogen gas boiler into the mainstream as a winter heating, natural gas is not only energy efficient, low-carbon environment, the country can meet the heating needs of sustainable development and environmental protection are two simultaneous, consistent with the development of the cause of energy conservation ideas , winter heating will become mainstream products in north and south China regions. In response to the national "energy saving" the call, further reducing boiler NOx emission from the country are carrying the boiler to Henan low nitrogen gas boiler. Currently, low-nitrogen transformation technology boiler there are three: First, the two-scale low NOx combustion technology, mainly for Corner Tangential unit, by controlling the scale of the transformation process and on the spatial scale to achieve three characteristic difference, resulting in two furnace three beneficial characteristics forming the anti-slag, the NOx is low, steady combustion of the scale function. Second cyclone low NOx combustion technology, primarily for the opposed wall units, by replacing coal burner and the transformation of secondary air, tertiary air boiler to reduce the nitrogen oxide content. Third W low - NOx combustion flame technique, the longitudinal arch boiler pulverized coal burner to a low NOx combustion is replacing a specific structure, to reduce the impact on the normal operation of the combustion tissue as possible, the structure of the secondary air substantially constant. These three low NOx combustion technology in the transformation have made good Jiangdan effect. Now, there are many small boiler (100MW units and below, primarily in the form of Tangential) also need to be low-nitrogen transformation, but if using conventional low-nitrogen transformation technology, investment costs are relatively high for small boiler is concerned, may not be bear, economic efficiency will also be affected. In view of this situation, we launched a small-scale low-nitrogen transformation technology boilers, control and transformation through major processes affecting boiler nitrogen oxides produced with a smaller cost of renovation to achieve the purpose of significantly reducing the concentration of nitrogen oxide emissions boiler.
The fuel of 130 ton circulating fluidized bed coal all premixed condensing boiler rank can be coal,gas,oil and biomass.with the development of the energy saving principle,there is no doubt that biomass is the most environmental friendly fuel for industry boiler.Compared with the traditional coal fired units, for the biomass power units, the emission of SO2 and NOx is greatly reduced, the PM2.5 content can be efficiently decreased in atmosphere and the local environment quality can be improved greatly.This is why the 130 ton biomass circulating fluidized bed boiler is one of the hot sale boilers in ZG company.
130 ton biomass circulating fluidized bed boiler adopts CFB technology map, saves the electricity cost and improves availability with all the advantages of strong adaptability for coal and low pollution emission.Therefore it is developed fast presently and it has get to be the most practical technology. The 130 ton biomass CFB boiler has made big breakthrough in low NOx combustion optimization control technology with many national patents.
AMD Power were to buy 10 tons of steam and one 4 tons of steam condensing steam coal all premixed condensing boiler rank fuel gas from the company for cell processing company production and construction. From the analysis of the demand to the boiler factory, by the company solely responsible for AMD Power fully demonstrated the company's confidence in me, the smooth progress of bilateral cooperation.
The heat exchange surface of Fangkuai coal all premixed condensing boiler rank is reformed reasonably: 1. The horizontal boiler is removed from the furnace arch of the original furnace, and the coal bed is covered with insulation layer and refractory brick, which is transformed into the secondary radiation surface. Vertical boilers can build radiation reactors at the bottom of the furnace and install radiation arches on the upper part of the tank. 2, control the leakage air volume of furnace and flue. It is necessary to seal the boiler's observation hole, to seal the boiler's air duct and flue, especially when the air leakage rate of brick air duct and flue is large, after changing to burning gas, it is necessary to carry on the sealing treatment, preferably to change to the metal flue. When multiple boilers share a total flue, each boiler Breakers should be installed on the flue to prevent flue gas and residual gas from the purging process from flowing into the boiler furnace that has ceased to operate. Reasonable selection of burners for Fangkuai boilers: 1. Under rated gas supply pressure, the thermal load of the burners must meet the requirements of the boilers. Combustion is complete, excess air coefficient is low, combustion temperature is high, combustion noise is small, furnace flame fullness is good, flame radiation ability is strong. 2, the load regulation ratio meets the requirements of boiler operation, and the excess air coefficient can be adjusted. 3, can realize the boiler safety technical supervision regulations issued by the Ministry of Labor automatic control project.
