fire tube steam boiler 20tph

Common thermal efficiency of gas-fired at about 80% -90%, since the exhaust gas temperature at the boiler more than 100 deg.] C, with a lot of heat loss of exhaust gas, it is a waste. Condensing gas boiler is to improve the thermal efficiency of the boiler by reducing the exhaust gas temperature, flue gas dew point of 55 ℃ -60 ℃, and the main component of natural gas is methane, a large amount of water when burned above the dew point of the gas, If the exhaust gas temperature is reduced to below the dew point, water vapor in the flue gas will be liquefied in the heat, this part can be recycled heat, it again increases the thermal efficiency of the boiler (flue gases into the cooling water will condense boiler corrosion , requires special corrosion-resistant materials). Usually calculated boiler thermal efficiency is used in the low calorific value, i.e. no latent heat in the flue gas condensing boilers while absorbing sensible heat and latent heat in the flue gas, calculated condensing boiler by Equation thermal efficiency reached 100%, the current maximum thermal efficiency of 108.9%.

Under the new economic era, serious product homogeneity, after-sales service is another important indicator selected by the user of the product. Fast boiler service customer service center escalating form, by telephone 400, after-sales network, remote monitoring, repair and other micro-channel multi-channel, multi-form to provide users with convenient and efficient service. To allow users to have more expertise in gas boiler operation, operation, security and other aspects, fast Boiler Group launched the safe operation of free training Week in April 2017, the first phase of training has been successfully concluded.

Objective 6 tons of gas fire tube steam boiler 20tph for low NOX combustion of natural gas steam boiler low NOx combustion is to improve the boiler efficiency, reduce air pollution emissions. Gas previous four stages in industrial applications: The first stage: the degree of understanding of the nitrogen oxides is not high, I do not know what will bring harm. The second stage: the beginning of the use of staged combustion to reduce the formation of NOX, this technology has been widely promoted in several countries. Third Stage: The staged combustion and flue gas recirculation are combined. The fourth stage: As emission standards, the industry for improved combustion technology, to staged combustion, flue gas recirculation of FGR, and the like based on a premixed low NOx combustion technologies.

Hazard 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.
