About Henan low nitrogen gas factory direct coal fired boiler 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 whole structure of normal pressure BoilerThe whole structure of atmospheric pressure factory direct coal fired boiler consists of boiler body and auxiliary equipment. The main components of boiler, such as furnace, boiler barrel, burner, water-cooled wall superheater, economizer, air preheater, frame and furnace wall, constitute the core part of steam production, which is called boiler body. The two main components of the boiler body are the furnace and the drum. The furnace, also known as the combustion chamber, is the space for fuel combustion. The furnace in which the solid fuel is placed on the grate is called a layer furnace, also known as a bed furnace; the liquid, gas or powdered solid fuel is injected into the furnace burning in the fire chamber, which is called a chamber furnace, or a fire chamber furnace; the air turns coal particles into the furnace, which is called a chamber furnace, or a fire chamber furnace; the air turns the coal particles into a chamber furnace, also known as a fire chamber furnace. It is called boiling furnace, also called fluidization bed furnace, in which the furnace with boiling state and suitable for burning inferior fuel is called boiling furnace, and the cylindrical furnace which uses air flow to make coal particles rotate at high speed and burns intensively is called whirlwind furnace. The furnace design needs to take fully into account the characteristics of the fuel used. Each boiler should burn the original fuel as far as possible. The economy and reliability of boiler operation may be reduced when the fuel with different characteristics is used.

Three major advantages condensing factory direct coal fired boiler will be used in many areas of the north to the boiler to heating, but the energy of the boiler in general are very high and there is a lot of waste to energy, various studies by experts wanted to try to change this situation eventually found a new condensing boiler and can indeed play a good energy saving effect is very good. In particular integral condensing boiler price the general public can accept this, and it has a lot of advantages, including the following aspects. First, the good thermal efficiency and energy savings compared with ordinary boilers up, condensing boilers can achieve a high degree, and its full use of energy is almost too much waste. Since the thermal efficiency of direct energy loss problem can be illustrated between the thermal efficiency and is proportional to the energy, so that it directly indicates the condensing boiler having a strong energy saving effect, in particular for heating with a user can save a lot of the day heating costs, even down to detailed calculations condensing boiler than the normal boiler save more than a third. Second, with strong durability and long life due to the condensing boiler design structure itself is relatively perfect, especially as such a heat exchanger core components are used in very special protection measures when it used to be more durable, by the action of various aspects of life can lead to greatly extended. Condensing boiler service life of about decades or so, than ordinary boiler twice the time according to the general rule of thumb, the whole is therefore very cost-effective. Third, can play a very good role in environmental protection in general condensing boiler used is relatively clean energy, such as natural gas or coal gas and therefore the use of the process of running there is little waste gas, which undoubtedly reduces air pollution for the city of in particular ease the polluted air of sulfur oxides, nitrogen oxides and played a very environmental protection. And because the high temperature flue gas condensing boiler can be condensed into a cryogenic liquid to save energy and improve the efficiency can be very good, so efficient and environmentally very practical. These are the three major advantages of condensing boilers, in addition to this experiment condensing boiler is also reflected in a very good performance and quality. Cast aluminum premix condensing boiler manufacturers emphasize as people's awareness of low-carbon environment using this boiler will be more extensive, and the future development of condensing boilers will show a more distinct advantage and gradually become the dominant market it is the general trend.

July 26, 2016, Beijing, China Everbright Paper Co., Ltd. and the company signed a "split 6 tons of steam condensing gas steam factory direct coal fired boiler contract" by the company responsible for the WNS6-1.25-YQ split condensing gas boiler steam to all production, installation and commissioning work. The product is the use of condensing technology, effective emission of harmful substances SOx, NOx, COx, is industrial boilers efficient and environmentally friendly solutions.
