steam boiler for dry cleaning machine manufacturer

WNS type fuel steam boiler for dry cleaning machine manufacturer scale inhibitors should be used with a boiler fuel WNS type steam boiler scale inhibitor effective to inhibit the use of copper and in the process, carbon steel composite member; anti Fe3 +, Cu2 + strongly accelerated corrosion capability. Selection of boiler scale inhibitor, is a guarantee of safety WNS-type fuel steam boiler; it can completely remove the scale at the same time easy to reduce; and simple operation, safe and reliable; boiler scale inhibitor is generally used free by It can be discharged after a simple neutralization treatment, safety and environmental protection. Use scale inhibitor performance of the boiler fuel WNS-type steam for maintenance, can be reduced in favor of direct use and regular cleaning and maintenance of user WNS type of fuel steam boiler, saving maintenance costs. In the cleaning process, H + will corrode the metal body, appears; and dissolved produced Fe3 +, Cu2 + ions and the like may cause oxidation of the metal body, such as copper plating, therefore, the boiler cleaning agent to be added corresponding. Descaling agent used according to specific circumstances WNS type fuel steam boiler operation, simplifies and facilitates the installation and operation of the washing site. WNS cleaning speed type fuel steam boilers, high inhibiting efficiency, the cleaning waste liquid treatment method is simple, advantageous for the cleaning.

Fangkuai Boiler has carried out a large-scale welding revolution, eliminating traditional manual welding operations with low efficiency, low accuracy and poor stability, and converted it to the use of mechanical welding equipment with high efficiency, high accuracy and high stability for automatic operation . Realize welding automation of all important parts from the drum to the tube sheet. The submerged arc welding, argon arc welding, carbon dioxide welding and other welding details of the process have also made corresponding intelligent changes, workers' welding environment is cleaner, and the quality of boiler welds is more guaranteed.

How to reduce the combustion temperature gas boiler Henan conventional low NOx combustion technique is mainly about how to reduce the combustion temperature to reduce thermal NOx generation undertaken Henan gas boiler main techniques include staged combustion, premixed combustion, flue gas recirculation, catalytic combustion porous media and flameless combustion. A, or fuel staging combustion air staging combustion thermal NOx generation largely depends on the combustion temperature. The equivalent ratio of the combustion temperature in the case where 1 is the highest, burned under lean or rich combustion cases, the combustion temperature will be much lowered. Using this principle has developed a staged combustion technology. Henan air staged combustion of gas boiler is a fuel rich combustion of the first stage, the second stage addition of excess air, the combustion is lean, the cooling air is added between the two to ensure that the boiler will not be too high combustion temperatures. Combustion air staging and fuel staging combustion contrary, with the first stage fuel lean combustion, fuel is added in the second stage so that the equivalent ratio required value is achieved. These two methods will eventually cause the excess air ratio of the entire system to maintain a constant, low nitrogen currently widely used as combustion control technique. Second, the premix lean premixed combustion technology Henan boiler combustion gas refers to fuel and oxidant completely mixed at the molecular level before the mixture is ignited. For controlling the generation of NOx, this technique has the advantage of controlling the combustion temperature can be achieved by fully controlling the equivalent ratio, thereby reducing thermal NOx formation rates, in some cases, partially premixed and the premixed combustion than non-premixed 85% -90% of combustion to reduce NOx production. Further, the premix can also be reduced completely to reduce the excess air ratio due to unevenness caused by generation control of NOx. However, premixed combustion technology there are still unresolved technical difficulties on the security control: First, because of its highly combustible premixed gas may cause tempering; the second is too high excess air ratio will lead to an increase in exhaust losses , reduces the thermal efficiency of the boiler.

Enterprises purchasing industrial boilers industrial boilers need to pay attention to what now is getting higher and higher, the market share of washing ironing, packaging machinery, biological, chemical and food industry, purchased the necessary equipment sets for industrial boiler is made of high quality stainless steel as the main timber, inlet temperature magnesium oxide powder as the sealing material, its heat resistant. However, when purchasing this boiler, should pay more attention to purchase cost-effective boiler by comprehensive evaluation. Enterprises purchasing industrial boilers need to pay attention to what a, pay attention to whether the device too much noise in the purchase of industrial boilers, noise reduction requirements lower than domestic boilers. Note, however, whether the device is too large noise, prevent noise pollution, environmental impact of industrial quality. Typically, a large boiler large vibration caused by noise can reduce the stability of the system, reduce the life of the respective parts, thereby reducing the whole life of the boiler. Second, note how the quality of main material (whether external corrosion) The main materials used in industrial boilers will directly determine its heat resistance. Most industrial boiler is made of stainless steel, and it is not necessary to select a thinner material of lower compression. In addition, you must pay attention to whether the boiler by external corrosion protection. Since the air under industrial conditions and the moisture content of highly corrosive substance, external corrosion the boiler, the boiler will look to reduce or avoid corrosion of the core. Parts affect the normal operation. Third, pay attention to environmental protection, energy efficiency of industrial boilers generally how must run 24 hours a day and must pay attention to the environmental protection at the time of purchase, to avoid over-consumption and produce large amounts of electricity; in addition, we should also pay attention to the environmental protection, especially for the environment protected areas more stringent requirements, should select the best industrial equipment, environmental protection boiler. Fourth, note that the availability of security devices (e.g., overvoltage and overheating alarm system)
