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.
There are two series of 15 tons of oil and gas boilers produced by ZBG. These two boilers are environmentally friendly packaging boilers carefully developed by ZBG. Many customers pay more attention to the price of the boiler, and the type and specific parameters of the oil and gas boiler will have a great impact on the price of the boiler. To know the price of a 15 ton oil and gas oil 12000 kg steam boiler costs, you need to have a general understanding of some specific information about the boiler.
Recently, Nanchang, Jiangxi Province to fully implement the national environmental protection work conference and the province's environmental protection work conference, combined with the actual situation of the city, issued a "blue sky Nanchang win the Battle of three-year action plan (2018-2020 years)" (referred to as " plan"). "Plan" put forward a management plan for major air pollution problems.
As the relevant departments to actively promote the utilization of clean energy. The city gradually reduce the proportion of coal consumption, by 2020, coal accounted for the proportion of energy consumption dropped to below 65%; principles and has gradually increased the proportion of natural gas energy consumption, adhere to "the electric power should", "should air the gas" to promote natural gas work to build the pipeline, steadily "coal to gas" project.
2018, the main city of Nanchang to the new area, the main city area and open small blue through the open area to expand the range of city ban on burning areas. By the end of 2020, Nanchang County, Jinxian, Anyi required scoping combustion zone ban within the jurisdiction of, and informed consent of the uniform implementation of the municipal government.
"Plan" put forward in 2018, the main city of the new areas into the combustion zone ban, the main city through the open area and a small blue through the open area phasing out the 10 steam tons / hour and coal-fired boilers; 35 tons of steam launch built-up area / out of hours and coal-fired boilers. As of 2020, the city built basically out of the region 10 steam tons / hour and coal-fired boilers, coal-fired boilers within 10-35 tons of steam / hour range is substantially complete alternative clean energy sources, and no longer approve new 10-35 steam tons / hour of coal-fired boilers.
Factors affecting boiler gas consumption SZS20 tons of gas vapors which gas consumption is influenced by three factors: 1. Calorific value of the fuel; 2. Boiler thermal efficiency; 3. Operating level fireman. So, if you want to consume as little fuel boiler over a period of time, there are several options: 1. Select efficiency gas furnace. A gas boiler type on the market a lot, have a variety, the price is different. Thermal efficiency between 85% to 95%, the heat efficiency is different from different manufacturers. Small boiler factory price is relatively low, but poor results. A price is true, so when the time to buy, do not look cheap, money is to buy a truly efficient boilers in the price. 2, select high calorific value gas. Different heating values of different fuels, different fuel heating value different origin. Just like oil, it is oil, but at a different price, per kilogram a few kilometers of oil is different. Of course, high calorific value, the price is relatively high. At the time of purchase, a good trade-off affecting the relationship between the price of both. 3, find an experienced operator. Regardless of the industry, when recruiting is like looking for the same experience, because experience is a treasure, you can do more things for the enterprise to save a lot of energy. Boiler workers, too, they save more money than those without experience. An experienced operator on a gas oil 12000 kg steam boiler costs can save 10 tons in addition to the cost of about 100,000 yuan, the user is also very worried about another problem: 10 tons of natural gas steam boilers. Specific cost depends on the manufacturing process, brand, product quality and other manufacturers.
