Wns Series Horizontal Oil Fired Steam Boiler

Boiler water treatment analysis of safety issues: the problem of boiler water treatment is an important part of the process of the safe use of boilers in general we all know that the market is now using more coal-fired wns series horizontal fired steam boiler, steam boiler fuel ratio or gas accounts for a large steam boiler most, especially in the current market share of imports of fuel gas-fired boiler in the market constantly rising, mainly due to fuel gas-fired boiler of compact, small size, high water quality requirements, at the same time, due to the oil and gas combustion temperature itself relatively high, therefore, be able to do is very important for boiler water treatment, boiler water treatment, if done well it will cause boiler fouling, corrosion, which not only wastes fuel and it can lead to blocked pipes, burst pipes and other accidents, and more there will also be scrapped boiler caused severe economic losses ***. Therefore, fuel oil and natural gas boilers must strictly check boiler water treatment problem seriously.

Why boiler furnace exhaust gas temperature increases heat losses the heat loss is largest in a boiler, furnace 6% is generally fed to the heat, the exhaust gas temperature increasing every 12 ~ 15 ℃, heat losses to an increase of 0.5%. Therefore, the exhaust gas temperature is one of the most important indicators boiler operation. Here are a few reasons may cause the furnace exhaust gas temperature rise: (1) heating surface slagging, fouling. Whether waterwall slagging furnace fouling, or superheater, convection bank, and economizer preheater fouling are due to increased resistance measured smoke, heat deterioration of the cooling effect deteriorates the flue gas, resulting in increased exhaust gas temperature. (2) the excess air ratio is too large. Under normal circumstances, the furnace outlet increases as the excess air ratio of the exhaust gas temperature rises. After the excess air ratio increases, while the amount of smoke increases, the speed increase of smoke, heat strengthening of exiled, but less than the degree of increase in heat transfer gas volume increases more. It will be appreciated as the tobacco rate increased, the time to heat to the flue gas working fluid left the heating surface. (3) leakage factor is too large. Tail shaft furnace and boiler flue negative pressure leakage is inevitable, and provides a heating surface allowed leakage coefficient. When the coefficient of air leakage increases, the influence of the exhaust gas temperature and overfire air coefficient increases similarly. And the closer the leakage furnace, exhaust gas temperature raising effect on the greater. (4) water temperature. When the turbine load is low or high pressure splitting when the heater temperature of the boiler feedwater will decrease. Generally, when the water temperature rises, if the amount of fuel is maintained constant, the temperature difference decreases economizer, economizer heat absorption decreases the exhaust gas temperature rises. (5) the fuel moisture. The fuel in the flue gas to increase the amount of water increases, and therefore the exhaust gas temperature rises. (6) boiler load. Although the boiler load increases, the amount of smoke, the amount of steam to the water, the air amount increases in proportion, but since the furnace exit gas temperature is increased, so that the exhaust gas temperature rises. After the load is increased to increase the furnace outlet temperature, followed by convection heating surface temperature difference increases, an increase in heat absorption, the more so the convection heating surface, the smaller the impact load change of a boiler exhaust gas temperature. (7) The fuel species. When burning low calorific value gas, since the furnace temperature is lowered to reduce the radiation heat transfer in the furnace, the low calorific value gas in a non-combustible components, mainly N2, CO2, H2O more, the amount of flue gas increases, the exhaust gas temperature rise high. Pulverized after burning oil, although oil-fired furnace outlet when the excess air ratio than the coal is low, but the little ash fuel oil, and no larger soot particles, larger ash particles in the flue gas absent the cleaning action of surface heating, convection heating surface more polluting. So bad combustion, often black smoke boiler flue gas temperature. When the tail has means ash ball, since the tail cleaner, the exhaust gas temperature is slightly lower than the burning coal. (8) milling system operation. Bunker has a reservoir of closed milling system is concerned, when the pulverizing system is running, because a portion of the water in the fuel into the furnace, the furnace temperature is reduced and the amount of smoke increases, the leakage into the pulverizing system is running as the primary cold air air into the furnace, to reduce the amount of air flowing through the air preheater to the exhaust gas temperature rises. Conversely, when the exhaust gas temperature is reduced pulverizing system outage.

Cade Shopping Mall is located in central Shanghai Hongkou District, Shanghai Daily larger flow of people in the region. The introduction of Shanghai air pollutant emission standards, boiler flue gas emissions of nitrogen oxide emissions to less than 80 mg / m, Shopping Mall a coal-fired boilers have been used for many years, NOx emissions far super to this request, the urgent need to replace more environmentally friendly low nitrogen emission boilers. Other units through the use of fast Boiler introduction and understanding, determined and fast boiler to achieve cooperation, party fast to their specific needs to recommend one condensing gas hot water boiler of a 4.2MW for heating needs of the shopping center.

Industrial gas wns series horizontal fired steam boiler for industrial use industrial gas steam boiler is a low-pressure gas steam boiler, but its high thermal conductivity temperature of the liquid inside, and the liquid explosive is mostly, if working in industrial gas steam boiler thrown thermally conductive fluid leak and cause a fire or even a large possibility of an explosion, which is very dangerous, so run industrial gas steam boiler safety is often worth the length of the face. Because the range of high temperatures (above 320 ℃), low voltage (0.3 to 0.5MPa), the heating temperature can be precisely controlled, it can replace the original steam boiler heating. Industrial gas steam boiler is heated up to a temperature of 350 ℃, molten salt furnace is heated up to a temperature of 530 ℃. Because the ash can not be produced by industrial combustion gas steam boiler fuel gas, if the gas and air mixture into the furnace is injected within a certain range may explode. Gas steam boiler operating temperatures above 400 ℃ oil and molten salt heat transfer medium, having a molten salt heat steam than the gas lifetime advantages, but otherwise are at a significant disadvantage, in particular the complexity of running the system.
