biogas operated industrial boiler

Hazard biooperated industrial boiler scale chemical plants which boiler scale chemical plants What are the dangers? In the application process chemical plant boiler, for various reasons, the main boiler heating surface will produce a lot of fouling, and briefly describes the main hazards fouling. 1, the scale will reduce heat transfer efficiency boiler, heat boiler operating characteristics of the waste fuel boiler has a very close relationship. Internal inspection understood from the boiler, the boiler heating surface fouling occurs, the higher the heating temperature, the stronger the boiling, the more prone to fouling. Operation Practice of boilers and various data indicate that damage to the boiler fouling is mainly caused by the thermal conductivity, the thermal conductivity of steel is 1/5, will result in decreased formation of fouling of heat transfer efficiency. Thermal resistance is increased because the heat from fuel waste, low thermal efficiency. Studies have shown that analogy than 1mm, we should consume 3 to 5% of coal per scaling in the boiler. 2, the scale will shorten the life of the boiler and endanger the safe operation of the boiler from GB713-2014 "boiler and pressure vessel steel plate" inquiry found that the mechanical properties of steel will increase as the boiler temperature decreases. After the scale generated water present in the heating surface side, so that the resistance increases, the heat generated by the fuel combustion is not well transferred to the boiler water by the metal surface, resulting in the metal heating surface temperature increases overheating, reducing the structural strength of metal, prone smoke tube deformation on drum kits, tube wall area reduction and other hazards, shorten the life of the boiler and related components, a serious threat to the safe operation of the boiler. Additionally, high iron containing scale, the scale is easy to cause surface lower oxygen corrosion, scale formation and corrosion promoting the mutual drum, resulting in surface defects such as corrosion pits within the drum, the safe operation of the boiler hazard. 3, the scale will affect the water cycle boiler water circulation boiler operation of natural circulation and forced circulation divided two kinds. Boiler circulating water is balanced, whether it is rising or falling pipe tubes, should have sufficient cross-sectional area. Fouling not only the cross sectional area of ​​the waterwall tubes in the boiler waterwall tubes is reduced, but also because of a greater roughness and unevenness, the larger the flow resistance of the boiler heating surface fouling of the boiler water or steam will have some impact on the flow, the line is blocked when the scale, water circulation is stopped, the convection tubes by local temperature rise generates firing tube or tube rupture occurred partially vaporized, direct threat to the normal operation of the boiler.

Gas biooperated industrial boiler works and the principle of gas-fired boiler of a gas furnace gas fired boiler is also known, in general is natural gas, liquefied petroleum gas, city gas and other combustible fuel gas to heat utilization equipment, according to their functions can be divided into different type, such as a gas hot water boiler, gas hot water boiler, gas steam boilers, gas and other industrial boilers, gas boilers as China's coal-fired boilers have been banned since a new type of economic energy-saving products, it is widely used in the boiler civilian areas, mostly for heating and bath with. Here to share a gas boiler operating principle: the working principle of gas boiler and substantially conventional boiler is connected, is injected through the burner head of the burner into the furnace to ignite the combustible gas-mixed flame, so as to achieve furnace of the boiler, heating furnace tube, such as a good boiler Henan party shares fast production of gas boilers will be designed on the basis of these three return bend the combustion chamber or multi-backhaul goal is to deliver more local temperature, and because it is multi-cycle, high-temperature combustion smoke is produced after several times through the loop, the temperature in the discharge thoroughly complete transfer. The whole process is most important boiler with burner heads and fuel, together with the overall thermal efficiency of the superheater, the effective mating of these components reheater, economizer, an air preheater and the like to achieve the lifting of the boiler. These are the working principle of gas-fired boiler, where our customers want to buy gas boiler recommend a good product, Henan local production SZS series shares quick and efficient gas boiler, the product is currently one of the most advanced energy-saving equipment, 1 tons the gas boiler can save up to 10 cubic meters per hour of natural gas, it is a rare quality products.

Steam biooperated industrial boiler is one of the indispensable devices in the pharmaceutical industry, decoction of Chinese medicine, medicine drying, sterilization, cooking gum, drying, tabletting and capsule production processes, a large amount of steam will be used. West Libang Pharmaceutical Co., Ltd. is a pharmaceutical research and development, production and sales of high-tech enterprises, the existing anesthesia, cardiovascular, child immunization, pharmaceutical raw materials, pharmaceutical excipients, nutrition series of six automated production lines. With the increasing strength of China's environmental protection, some high-pollution devices are making the transition to clean environmental protection. Libang Pharmaceutical respond positively to national coal to gas policy, decided to change the existing coal-fired boilers to clean better gas steam boiler. Fast boiler with strong comprehensive strength in the field of clean energy, Libang Pharmaceutical after conducting comprehensive consideration, determined to cooperate with the fast boiler. The two sides further understanding, party fast technical engineers according to production needs state power, and soon its development of specific solutions for its recommendation of a 6 tons of steam condensing gas steam boiler (WNS6-1.25-Y.Q).

(1) biooperated industrial boiler feed water quality is not good, long run down the accumulation of a lot of scale, decreased heat transfer efficiency heating surface. Scale thermal resistance is 40 times that of steel, 1mm of scale will increase fuel consumption by 15%. Scale drum can be opened to check the situation, the exhaust gas temperature can be detected to determine whether there is fouling, if the exhaust gas temperature higher than the temperature given in the drawings, which can be caused by scaling is determined.

Boiler (power generation) - Wikipedia

A boiler or steam generator is a device used to create steam by applying heat energy to water.Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure (72,000 kPa or 1290 psi) but, at pressures above this, it is more usual to speak of a steam generator.
