Industrial boiler market share rise, to the current trend of energy-saving industry, industrial boilers are mainly used in metallurgy, chemicals, coke, cement, paper, shipbuilding and other industries, mainly through heating boiler, steam production unit each to provide the required or hot water. Different transformation and power industry, industrial boilers since often small cell capacity, installed at the rear end of expensive desulphurization and denitrification apparatus is very uneconomical, so the transformation of coal will be the main alternative route, the coal gas, biomass fuels, cleaning three coal technology route, clean coal will assume the main task. By the end of 2011, the total industrial boilers reach 58.5-60 million units, of which the boiler, the capacity accounted for more than 80% of coal-fired boilers, boiler capacity is less than the number of 35 tons / hour of 96% of the total, while 10 accounting tons / hour up to 80%. Meanwhile, the average thermal efficiency of industrial boilers only 60%, 20-25% lower than in other countries. The country's industrial kilns more than 160,000, concentrated in building materials, metallurgy, chemicals and ceramics and other industries, the annual coal consumption of 300 million tons. The average heating furnace thermal efficiency of only 40%, 10-30% lower than in other countries. A wide range of large industrial boilers in China, the average capacity of small and dominated by coal. Although China's coal-fired industrial boiler design productivity gap compared with foreign small, but the actual operating efficiency of only 65%, 10% -15% lower than the advanced level. Industrial boilers with maximum downstream chemical materials and chemical products manufacturing market size, non-ferrous metal smelting and rolling processing industry, petrochemical industry market size is large, in addition, the market size paper and shipbuilding industries is relatively small, moderate growth in the cement manufacturing industry . Overall, the future of Chinese boiler market demand is still the main metallurgy, chemical and petrochemical three coking industry, and paper, cement and other industries demand is relatively weak, shipbuilding recession has not slowed. Industrial boilers, especially coal-fired industrial boilers for energy saving is important for achieving the overall goal of energy conservation.
Measures to improve the thermal efficiency of the fuel gas-fired boiler wns type of chemical oil-fired boiler which is incomplete combustion heat loss and mechanical incomplete combustion heat loss. Because almost no ash after combustion of the gas boiler, solid and liquid fuels without mechanical incomplete combustion, there is no need to consider the mechanical incomplete combustion of the gas boiler heat loss. In all heat losses, heat losses have tremendous proportions, when the high thermal efficiency of boilers, heat losses so the total loss of the main heat losses of fuel gas-fired boiler flue gas heat loss is the exhaust gas temperature and For air excess factor. When the exhaust gas temperature decreases, high thermal efficiency can be obtained, for example, a conventional three-pass 10 ton steam boilers more information in thailand, furnace used in the past straight and smooth smoke tube, must increase the heating surface is arranged to make the exhaust gas to an acceptable degree, the theoretical discharge around the smoke heat loss. Potshell causing significantly increased diameter, wall thickness increased, greatly increased metal consumption, thus further reducing the exhaust gas temperature should be greatly restricted. From the aspect of heat transfer is not only now consider only the heated area, the use of new technology enables heat transfer performance significantly increased, the difference between the heat transfer overcomes the disadvantages of the past performance of the boiler, so that the exhaust gas temperature decreases, the structure is more compact. Center back boiler combustion boiler is preferably small foreign structure, although the two-pass boiler, the heated area is small, but the use of the turbulator charming, the purpose of enhancing the turbulence of the flue gas, disrupt laminar flow boundary wall, reducing the thermal resistance, increasing the heat transfer coefficient, a smaller heating area to achieve the same high thermal efficiency. Lower exhaust gas temperature limit in theory, the exhaust gas temperature can be reduced to very low or even close to the ambient temperature, for maximum thermal efficiency. However, in practice, due to the reduction of the exhaust gas temperature, low temperature corrosion will cause, therefore, the exhaust gas temperature can drop too low, in order to ensure that the wall temperature is higher than the main boiler heating surface flue gas dew point temperature. Therefore, low-temperature corrosion has become a major obstacle to reduce exhaust gas temperature and improve the thermal efficiency of the boiler. Tail auxiliary heating surface increases, further reducing the exhaust gas temperature, fuel gas wns improve thermal efficiency of the boiler as the oil, gas fuel burn easily wns type gas boiler air preheater generally not disposed. The economizer means is a common energy, which can be recycled flue gas was able to effectively reduce exhaust gas temperature. Separation type condensing gas boiler is out of the main boiler heating surface, the installation of the condensing heat exchanger. In one aspect of the flue gas absorption can significantly reduce the smoke temperature, reducing heat losses, on the one hand the absorption of part of the potential condensing water vapor released, increasing the effective use of heat of the fuel. Ash cleaning, to ensure that the heating surface of the scale wns boiler thermal efficiency of the boiler, the presence of soot fouling and heat transfer resistance increases, reducing the heat transfer effect. The thermal conductivity of the scale and soot is almost of the same order of magnitude, with the increase in scale, soot, the exhaust gas temperature rapidly increases, the thermal efficiency is significantly decreased. So, keep the boiler heating surface inside and outside clean, efficient heat transfer, thermal efficiency and to ensure the safe and economic operation of boilers, boiler fuel gas-fired boiler ash cleaning is required.
After installation and commissioning fast Boiler professional and technical personnel, two hot water boilers to provide our bodies quickly into the orbit of the normal operation. Meanwhile, the design of energy-saving equipment also effectively improve the thermal efficiency of the boiler, saved us a huge amount of fuel costs. --customer feedback
Vertical projection which features good 10 ton steam boilers more information in thailand boiler having a vertical steam energy conversion device, the input of thermal energy by chemical, electrical, and high temperature flue gas to the furnace, thereby converted into electrical energy, and to provide the desired life for people heat, on the safety and convenience of all with excellent product qualities, then what good salient features vertical steam boiler has it? 1, reliable safety performance vertical steam boiler in terms of product safety has a lot of protection, by ground fault protection, overvoltage protection and power protection and other measures to make operation of the boiler can always be in a safe state, when the pressure is too low or there is leakage, the boiler will cut off its own power button, so to ensure the life and personal safety of the boiler. 2, the portable vertical steam boiler operation which is preferably used, which have to see ease of operation and convenient operation of the boiler does not require user intervention excessive production process, just to the introduction of the electric power source control box start button to enter the automatic operation state, and when the job if the amount of water in the furnace suddenly reduced, the vertical steam boiler control system is also used to automatically replenish the water in the water tank to fill the pump through the apparatus in order to achieve high efficiency of production operations process. 3, small size and yield stability compared with the conventional boiler products, the type and volume of the vertical steam boilers are an advantage, not only a wide range, and the volume of the boiler is very small, but it has a large steam room to make product productivity and quality are the most significant upgrade in order to obtain a more stable production company that won the biggest profits.
