cost of production of waste heat boiler

Low nitrogen gas cost of production of waste heat boiler NOx causes and solutions to reduce NOx: nitrogen gas boiler low NOx generated into thermal-type NOx (ThermalNOx), fast-type NOx (PromptNOx) and fuel type NOx (FuelNOx). Gas lower nitrogen content, therefore, is not its primary fuel NOx control type. Thermal NOx refers to NOx combustion air at a high temperature oxidation of N2. On the thermal NOx formation mechanism commonly used in the Czech Popovich channel mechanism: When the temperature is lower than 1500 ℃, the heat generation amount of NOx is small; Above 1500 ℃, the temperature is increased 100 ℃, the reaction rate will increase 6 to 7 times. In the actual combustion process, since the temperature distribution in the combustion chamber is not uniform, if there is a local high-temperature region, the NOx generated in these areas will be more, it may be the entire NOx formation in the combustion chamber plays a key role. In the case of prompt NOx combustion of hydrocarbon fuel and fuel-rich reaction zone will quickly generate NOx. Various factors alone changes in the actual combustion process, a number of parameters are in constant flux, even the simplest of combustion of gaseous fuel, the fuel and air should be subjected to mixing, combustion flue gas, until the last to leave hearth. The degree of mixing temperature of the furnace fuel and air, flue gases in the furnace and residence time of these parameters have a great effect on NOx emissions are in constantly changing. After the fuel and air mixture into the furnace, due to the surrounding high temperature flue gas convection and radiation heating the mixture stream temperature quickly rises. Upon reaching the ignition temperature, the fuel begins to burn, when a sharp rise in temperature to a level close to the adiabatic temperature.

Poor water quality or improper maintenance of cost of production of waste heat boilers will often cause corrosion of metals. After corrosion of boiler, not only the effective thickness of metal will be thinned, but also the metallographic structure of metal will be destroyed, the mechanical properties will become worse, the pressure bearing capacity of boiler will be reduced, the service life of boiler will be shortened, and even be scrapped in advance. Some corrosion will cause damage to the equipment without people noticing, and some may even cause catastrophic accidents, such as boiler explosion, if they are serious. Therefore, corrosion prevention is also an important measure to ensure the safe operation of boiler.

What optimization measures industrial cost of production of waste heat boiler water boiler plant optimization measures water quality of industrial plant optimization measures which industrial plant boiler water which has 1, an industrial boiler water treatment plant (1) Sample preparation by lime softening process and the soda lime softening implementation, simple treatment of raw water impurities, pH, ions or the like by the above chemicals. First preprocessing the raw water before precipitation, filtration and condensation, thereby reducing impurities in raw water, reducing the amount of scale in industrial boilers; secondly, to process the raw material bicarbonate water by milk of lime, reducing the external water industrial boiler hardness; again, to use the soda lime softening treatment, to adjust the pH of industrial boiler water; Finally, the use of softened plaster, suitable to reduce the concentration of bicarbonate in water by chemical reaction with the sodium salt of gypsum, reducing boiler the C02 gas. Implement (2) in the process of softening primarily by exchange of sodium ions, the original metal cations of the water absorbed by a sodium ion exchanger to reduce the generation of scale in industrial boilers, which has a very positive safeguard industrial boilers for normal use. Process uses a sodium ion exchanger will increase the concentration of chloride ions is appropriate, therefore during processing to properly control the amount of sodium ion exchange agent, chloride ions to prevent sodium ion exchanger caused by excessive use of excessive. Process (3) may be suitably oxygen treated to enhance the boiler temperature, the thermodynamic oxygen, thereby reducing the corrosion rate of the boiler. The method of using the heating process to control water temperature above 105 ^ 0, in order to enhance the effect of oxygen may also be provided deaerator water spray disk. 2, the process of industrial boiler water treatment plant in the boiler water may be appropriately alkali treatment, phosphate treatment and adding sodium humate treatment: can be made to improve overall water quality in the boiler by the above method, adjustment of industrial the pH of the boiler water, total alkalinity, sodium ion concentration, has a very good effect on the optimization of industrial boiler water quality. Alkali treatment process may be suitably added to the people in the soda boiler, to form calcium carbonate and magnesium hydroxide by reaction of substituted acid salt sediment, reduce the concentration of magnesium ion concentration of carbonate ions in the water and calcium ions and metal. Plus phosphate treatment process may be employed in the reaction with magnesium metal phosphate ions and calcium metal ions, alkali treatment and the nature of the same, after removal of the sewage generated crystals. During the addition of the sodium humate treated mainly by the hardness of the softened water sodium humate, magnesium and calcium ions removed, soften water. 3, industrial sewage treatment plant boiler boiler blowdown process as a key industrial boiler water treatment, have a very positive significance to enhance the safety performance of industrial boilers. Industrial boilers during use due to evaporation of water and adding other agents, the concentration of the boiler water will gradually rise and a certain impurities in the boiler, precipitation and the like. Therefore, during the processing of industrial boilers regularly to turn on the water, will be discharged from the high concentration of water in the pot boiler. In addition, you also need regular cleaning and maintenance of industrial boilers, the use of chemical materials on the scale inside the boiler completely clear, so as to ensure clean the boiler heating surface, extend the life of industrial boilers.

Condensing a portion of the air preheater and use of double combination economizer design. Internal economizer heat exchanger elements using the new technology - the wings of the tube instead of finned tubes, a five-fold increase in heat transfer area at the same volume, latent heat of vaporization of the portion of the flue gas is sufficiently absorbed, effective utilization of the fuel energy, energy saving at the same time enhance the efficiency of the use of the cost of production of waste heat boiler. Air preheater is further absorbed by the air and the flue gas convection heat latent heat of flue gas, and the air heated by the air preheater is connected directly into the burner tube, providing warm air for the fuel, thus improving combustion efficiency. This exhibition brings Chinese fast "Euromonitor" series boilers attracted a large number of customers, to give customers unlimited. Here, fast Boiler staff wish the exhibition every success.
