Learn the difference between pay professionals work and waste boiler and boiler feed water for boilers of knowledge and understanding, we will continue this work, because the only way to keep abreast of professional knowledge about the boiler, and the knowledge and flexibility to apply their knowledge applied to practice, then, to ensure that the boiler had good results, avoid misuse. 1. What is the boiler professionals work? Boiler professionals work, the specific name for the boiler professional engineers and professionals work into operation and maintenance professionals work. Run professionals work: the development of operational procedures, technical monitoring in the boiler, if the boiler fails problems during operation, timely analysis and guidance to operating personnel discharge failure, ensure that the boiler safe operation. Also, record the operating parameters of the boiler, to provide accurate data for the boiler overhaul. Maintenance professionals work: development of maintenance procedures and maintenance scheduling and parts planning, at the same time, but also to develop maintenance programs, guidance personnel for maintenance work as maintenance procedures. Boiler feed water and boiler feed water 2. Is there a difference? Boiler feed water, which is from the plant to the Water and then through oxygen between the boiler feed pump into the boiler economizer soft water, boiler feed water is from the chemical water softener after the plant by chemical treatment. Although they are soft water, boiler feed water, but more complicated, but also the need for oxygen and heated before entering the boiler. So, boiler feed water and boiler feed water is different. 3. central boiler furnace temperature to be controlled in a range? The boiler is the first inspection within or outside the check? Central boiler furnace temperature is generally controlled within the required range of 900 ℃ -1100 ℃. Is the first in the boiler inspection, conducted after the external examination within the inspection is completed, if the problem has been found in the inspection process, and after dealing with external inspection out of the issue. In addition, we also need to know that, in the boiler inspection is conducted every two years, external examination is conducted once a year. 4. What is the waste boiler? Familiar with and understand the waste before the boiler, first look at waste boiler. Waste boiler, which means that the exhaust gas, waste and waste water. Exhaust: no fuel to burn in the combustion waste air emissions, mainly including soot, sulfur dioxide, nitrogen oxides and other waste gases. Waste: solid waste produced after combustion of the fuel, including cinder, oil residue and other such waste. Waste water: Some water is not used in the boiler emissions, comprising a compound, mixture, suspension, and salt, alkali larger boiler water, in addition, also water, sludge and the like fluffy precipitate. Waste boiler, which is the use of some of these techniques and recycling waste utilization, and reduce noise to produce secondary economic benefits.

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.
