Fangkuai boiler for you to sort out 30 boiler operation common problems and solutions, after learning, do not forget to share with your friends oh. (6) what are the main factors affecting the wear rate? 1 flue gas, 2 flow rate of the material, 2 particle size of the material in the flue gas, and 3 the surface shape of the worn component. The velocity of air flow is the most important factor affecting the relative direction of motion of the worn material and the wear is proportional to the third power of the velocity. 7. Why should the bed temperature be controlled between 850 and 950? 1 the ash will not melt at this temperature, thus reducing the risk of slagging 2. Higher desulfurization efficiency 3 less nitride gas in combustion gas at this temperature 4 Alkali metal in coal does not sublimate at this temperature, which can reduce slagging on the heating surface. 8, why do you have to blow the boiler pipe? Some equipment in boiler steam-water system, such as dewarming water, start-up bypass, superheater, reheater pipeline system, are not suitable for chemical cleaning due to structure, material, arrangement and other reasons. So it is necessary to use the physical method to remove the residual debris before the new boiler is put into operation, so the steam produced by this furnace is used to blow the steam-water system and equipment. 9, what are the common methods of boiler maintenance? (1) Wet protection: there are diammonium method, ammonia method, maintain feed water pressure method, steam heating method, alkali liquefaction method, trisodium phosphate and nitrous acid mixed solution protection method; (2) dry protection: there are drying method (with pressure discharge) and desiccant method. 10, which causes the deterioration of steam quality (steam pollution)? (1) steam with water. The boiler's feedwater contains impurities. The feed water is heated into steam after entering the boiler, and most impurities are transferred into the boiler water. So many cycles, the impurity concentration in the boiler water becomes higher and higher. Furnace water containing high concentrations of impurities is carried by saturated steam, which is called steam carrying water, which is called mechanical carrying. The first reason for steam pollution. (2) Steam-soluble salt. At higher working pressure, steam can dissolve some salts, which is called selective transport, which is the second reason of steam pollution.

Gas-fired fired steam boiler supplier in darbhanga has a positive effect on sustainable development: the increasingly tense in recent years as the price of coal and coal supply more of our day to rise, more and more companies turning to heating gas heating from the traditional gas heating, gas-fired steam boiler heating for its environmental protection, energy conservation in the country has been more widely used, in particular, focus on the most popular heating gas boiler room. From an economic analysis using gas steam boiler operation point of view, generally more than 5 years of small and medium sized gas steam boiler no longer have the value of the Burning gas. Many of our cities in a few years ago began to control the construction of small and medium sized gas steam boiler, the boiler was included within the scope of the demolition basically a longer useful life or the furnace has been out of the product. Be evaluated by the thermal efficiency of a steam boiler and to detect the remaining useful life, with the new gas boiler economic comparison can be seen, simply to change the method of gas fired boilers have undesirable manner by replacing the burner. Gas-fired steam boiler is the ideal replacement for gas steam boiler. Although the thermal efficiency of the fuel steam boiler was also higher, but the smoke pollution in the atmosphere is much larger than gas-fired boiler, steam boiler fuel and there are also issues related to oil transportation and storage, it lost the advantage of long-term development. Gas steam boiler and a steam boiler with gas as compared to the obvious advantages: Since the gas in the ash, sulfur and nitrogen-containing volume is lower than the content of the coal, the amount of dust generated in the flue gas after combustion minimal emissions the flue gas is easier to meet the standards required by the state of combustion equipment, the use of gas-fired boilers can greatly reduce the pollution of the environment. A high intensity gas furnace volume the hot steam boiler, due to the small smoke pollution, a strong convection tubes from corrosion and slagging, heat transfer effect, a large amount of combustion gas triatomic gas radiation, and low exhaust gas temperature, make thermal efficiency improved significantly. Aspect of saving the equipment investment boilers, gas steam boiler furnace may choose a higher thermal load, thereby reducing the volume of the furnace. Heating surface due to contamination, slagging, there is no problem of wear, can use a higher-speed cigarette, to reduce the size of the convection heating surface. Reasonable arrangement convection tubes, so that the capacity of the gas boiler with gas boiler more compact structure, small size, light weight, reduced investment in equipment significantly. Why is it so popular environmental protection boiler
