2000KW Coal Fired Hot Water Boiler
Steam boiler steam boiler price Price: works steam boiler is heated in the drum and water is converted into steam, fire gives off heat in the furnace. Qiang boiler plumbing materials sales center is located in the southern suburbs of Datong City, is a design, sales, installation and service of integrated modern enterprise management. The main environmental operating boiler, a steam boiler fired boiler, a heating furnace, steel radiators, cast iron radiators, canned motor pump, the pump piping, air-conditioning water, galvanized pipe, PP board tanks. Details can be found! Works (in Pulverized example) in the furnace pulverized coal combustion heat is first absorbed water wall heat transfer by radiation, boiling and evaporation of the water wall to enter a large amount of steam for steam separator drum (excluding the DC furnace), into the separated saturated steam superheater heated by flue gas at the top, and the horizontal flue gas flue continue to be absorbed radiation and convection, superheated steam reaches a predetermined operating temperature. Generating boilers usually equipped with a reheater is heated by high pressure steam cylinder. Reheater steam power generation is continued into the low pressure cylinder. 1, the working principle (as an example in pulverized coal fired boilers) in the furnace pulverized coal combustion heat is first absorbed water wall heat transfer by radiation, boiling and evaporation of the water wall to enter a large amount of steam for steam separator drum (except for the DC furnace ), the separated saturated steam enters the superheater heated by flue gas at the top, and the horizontal flue gas flue continue to be absorbed radiation and convection, superheated steam reaches a predetermined operating temperature. Generating boilers usually equipped with a reheater is heated by high pressure steam cylinder. Reheater steam power generation is continued into the low pressure cylinder. 2. Pulverized coal boiler operation, the position of the center of the flame will affect evaporation. Generally, low center of the flame will lead to greater evaporation, and the high center of the flame will lead to slow evaporation. Also affects the position of the center of the flame superheated steam or reheat steam temperature. Typically, superheated steam, in particular the reheat steam temperature in the lower center of the flame, and vice versa. 3. Pulverized Coal Burner front and rear walls is arranged a thrust manner, tangential firing mode, bis tangential firing methods, each method has its own characteristics. Since the above-described arrangement can not be applied in the same furnace at the same time, the influence of steam can not be directly determined.
At the same time the 58MW circulating fluidized bed 2000kw coal fired hot water boiler has good fuel adaptability, not only with the bituminous coal, lignite and other flammable combustible coal, also can use anthracite coal, can also burn bark, garbage and other biomass fuels, the heating company to buy fuel way is broad.
Low temperature corrosion of boiler fuel than coal-fired boilers serious reason these days after another customer asked why there are low-temperature corrosion of boiler fuel serious than coal-fired boilers, small and together we discuss in this article address this issue. When little understanding of the chemistry of you might know equal sulfur content greater body oil and coal, but asked what the low-temperature corrosion of boiler fuel in general it is much more serious than the coal-fired boilers? For two main reasons: a coal-fired boiler, pulverized coal fired boiler in particular, 90% of the coal ash in the flue gas is taken away, fumes generated in the sulfuric acid vapor is adsorbed by fly ash in the flue gas, so that the smoke sulfuric acid vapor in the gas is reduced; coal combustion, about half of the sulfur remaining in the ash. While combustion of oil, the sulfur content of the fuel is almost complete conversion of SO2, the fuel ash few, little fly ash in the flue gas, the flue gas adsorption capacity of the sulfuric acid vapor is weak. 2. higher hydrogen content fuel oil in the boiler, about 11% to 12%, combustion can produce about one ton per ton of fuel vapor, when the fuel in the flue gas water vapor partial pressure higher than when coal, lignite but because it contains more water exception table below. Above the dew point of water vapor in the flue gas so that the fuel for two reasons, the concentration of sulfuric acid vapor in the flue gas is large, when the sulfuric acid vapor in the flue gas is not only a so-called thermodynamic point of water vapor partial pressure is low is formed, as shown in Table 1 shown in FIG. When the flue gas in a small amount of sulfuric acid vapor, the flue gas dew point of significantly increased. Effect of sulfuric acid concentration on the corrosion rate is large, typically at a sulfuric acid concentration of 40% to 50%, the fastest etching. Due to the fuel, the flue gas dew point is not only high, but the sulfuric acid concentration in the air preheater heating surface is also formed large, not to say in small series, we will come to a low temperature corrosion of boiler fuel ratio of coal-fired boiler this conclusion is serious.
Inner Mongolia Autonomous Region Development and Reform Commission issued a notice publicity Inner Mongolia clean heating in winter embodiment (hereinafter referred to as "Notice"), "notice" mentioned that in 2019 the region to achieve clean heating rate of 50% in 2021 to reach 705; urban built New forbidden zone 35 tons of steam / hour and below the coal-fired boilers, which Hohhot, Baotou, Wuhai city urban area will phase out 35 tons of steam / hour and below the coal-fired boilers, all new buildings to achieve clean heating.
The region's total heating area of about one billion square meters of urban heating an area of about 750 million square meters, of which: decentralized heating an area of about 090 million square meters; central heating an area of about 660 million square meters, heating rural area of about 250 million square meters, of which central heating an area of about 027 million square meters, the rest are dispersed heating.
Urban areas mainly in the CHP and district heating central heating boiler room mainly to gas, industrial waste heat, wind power, solar and other energy sources to supplement heating. Rural areas with decentralized heating the main heating source mainly scattered coal-fired boilers, conventional coal-fired furnace or straw.
Urban district heating cogeneration accounted for 51.5%, the proportion of area of 43.6% heating boiler, gas heating accounted for 4.5%, the proportion of the heat pump in other ways, electric heating and the like about 0.4%.
To clean as the goal, in ensuring the safety of people's livelihood heating premise, overall thermodynamic equilibrium between supply and demand, either alone or using a combination of various cleaning heating mode, alternative urban area and would like to keep burning coal for heating casual, less warm air pollutants areas emission. Adhere to safety bottom line, build a reasonable size, safety and reliability of heat supply systems.
2, according to local conditions, the residents can afford. Based on natural resources, economic strength, infrastructure around such as regulation and install air pollution control requirements, scientific assessment, depending on the region to its own characteristics, full old people's consumption capacity, adhere to both energy security and clean development, should power the electricity, should be coal is coal, the gas should be air, clean heating strategy adopted XI, to promote its low cost and low pollutant emission cleaning combination heating under the same conditions.
Considering the urgency of the air pollution control, affordability, work to promote the difficulty and other factors, co-ordinate the work of promoting cleaner heating city, county and urban-rural.
