shoe industry gas steam normal pressure fire tube boiler

Industrial shoe industry steam normal pressure fire tube 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.

Gas steam shoe industry steam normal pressure fire tube boiler and the hydraulic classification precision classification by use gas steam boiler 1, an industrial gas steam boiler: heating and the like used in industrial production. Most of the parameters for the low, low capacity boilers, the fire bed combustion and thermal efficiency is relatively low. 2, power station boilers: mainly for power generation. Most high-parameter, large-capacity boiler, firebox and allow more efficient combustion. 3, the ship's boiler: a marine power. Such boilers generally low parameters, fuel oil, the requirements of small size, light weight, easy to move more. 4, locomotive boiler: The main use of locomotive power. Lower overall parameters are small capacity boilers, fire bed combustion, requires compact, movable. Two gas steam boiler in accordance with the kind of the working fluid and an output state classification can be divided into: 1, the steam boiler: the working fluid is steam outlet. 2, hot water boiler: hot water as the working fluid outlet. 3, special working fluid boiler: export of special working fluids, such as certain organic matter. Three outlet gas steam boiler in accordance with the pressure of the working medium can be divided into: 1, pressure boiler: the outlet steam pressure 14MPA (140kgf / cm). 2, high-pressure boiler: the outlet steam pressure 10MPA (100kgf / cm). 3, sub-pressure boiler: the working fluid outlet pressure of 2.5MPa. 4, pressure in the boiler: the outlet steam pressure of 3.9MPa (39kgf / cm). 5, supercritical pressure boiler: outlet steam pressure is about 25MPa (about 250kgf / cm). 6, subcritical pressure boiler: outlet steam pressure of 17MPa (170kgf / cm?). 7, low-pressure boiler: the outlet refrigerant pressure (gauge pressure) is less than or equal to 1.3MPa (13kgf / cm). Accuracy of the hydraulic machine, determines the precision of the parts. However, only static accuracy to measure the level of accuracy of press is not very accurate. This is because the size of the mechanical strength of the press itself has a great influence on the punching accuracy. If the strength of the press itself is low, the machine will be modified such that the pressure at the instant of Ao punching pressure is reached, so that, when the above-described conditions in a static tune even good, also since the strength of the deformation caused by the sample bed, differences occur. This indicates that the accuracy of the press and has a lot of strength, and the magnitude of the intensity of the work has a great influence on the press, so that high-precision parts and punched continuous strong cold stamping, the accuracy must be selected high, and the rigidity of the press.

Strict accordance with the operation of the gas steam shoe industry steam normal pressure fire tube boiler feed water softening process is provided gas steam boiler fouling not only reduces the thermal efficiency of the boiler, but also increases the temperature of the boiler heating surface, damage to the heating surface, even causing the boiler explosion. Thus, soft water treatment equipment, strict accordance with the operation of the boiler feed water softening processing apparatus, the control of boiler feed water quality, delay the formation of scale. At the same time, real-time control the size of the boiler, boiler scale control, cleaning the scale, if necessary, it is very important. Since the gas steam boiler and vapor - water heat temperature is higher than the temperature of the air system of the boiler room, part of heat to the surrounding air by radiation and convection, which became the heat loss. boiler. Accordingly, when the insulating layer and the heat pipe of the boiler system damage or leak is detected, it should be repaired, to reduce heat losses. Steam boiler burner gas noise increases, mainly because of lack of or close the valve in the oil passage into the oil, oil filter plugging; or into the oil due to the low temperature viscosity is too high or oil pump. Temperature is too high; oil pump failure; fan motor bearing damage; dirty because the turbine wheel, the device too loud. When said failure when using gas boiler, and since the viscosity of the oil is too high, atomization is not easy (heavy oil); and because the distance between the nozzle and the cyclone unsuitable; In addition, since the burner worn or dirty; also because reserve tank temperature is too high, leading to the oil pump steam; oil boiler or because the oil is hydrated. Gas steam boiler feed water containing various impurities and calcium and magnesium scale substances, boilers inevitably expanded. Very low thermal conductivity of the scale, once contaminated surface is the surface heat, the exhaust gas temperature of the boiler will increase, and due to the increase in thermal resistance, heat loss of the exhaust gas will increase. Experimental data show, 1mm scale formation in boiler heating surface, the heat loss of the exhaust gas will increase from about 2-4%. Scale thicker boiler heating surface, the greater the resistance, the lower the thermal efficiency of the boiler.

As a leader in the fast side condensing gas shoe industry steam normal pressure fire tube boiler, in recent years, provide a clean boiler to Beijing multiple office units, was well received. I units through the preliminary investigation and contrast, select fast boiler, it turns out, party fast product does have quite a good cleaning environmental performance, in line with the Beijing municipal government requirements for air pollution emissions, the use of very at ease. --customer feedback
