If you know a little about chemistry, you may know that the sulfur content of oil and coal is roughly equal, but ask what low-temperature corrosion of oil-fired boilers is much more serious than coal-fired boilers, for two main reasons:
1. 90% of ash in coal-fired boiler, especially coal powder furnace, is taken away by flue gas, sulphuric acid steam formed in flue gas is absorbed by fly ash in flue gas, so that sulfuric acid vapor in flue gas is reduced, and about half of sulfur remains in ash when coal is burned. When the oil is burning, the sulfur content in the fuel almost all changes to the ash in the SO2, fuel, the fly ash in the flue gas is very little, and the adsorption ability to the sulphuric acid vapor in the flue gas is very weak.
2. The hydrogen content of oil in the oil-fired boiler is about 11%-12%. The combustion of each ton of fuel oil can produce about 1 ton of water vapor, and the partial pressure of steam in the flue gas is higher than that in the case of coal-burning.
Thermal efficiency of coal-fired boilers and boiler standard reference card Is there a difference: in the specific types of boiler, the following will explain to, this kind of boiler coal-fired boiler, and its Web site or in the product, so it is very it is necessary to become familiar with and understand, so that, in order to have a comprehensive understanding of the product website, and also to broaden their knowledge and thus, in its study on the road forward. 1. oil-fired boilers and coal-fired boilers that heat the surface of the furnace, Is there a difference? Fuel oil and coal-fired boilers, which are two major types of boiler, the boiler is in this category, but they get hot surface of the furnace, there is a certain difference, is different, so the on this issue, that the answer is yes. In addition to an outer surface heating furnace, there are differences in other aspects. 2. coal-fired boiler, if it is less than 1 ton of steam, then, the thermal efficiency is how much is? Coal-fired boilers, if it is less than 1 ton of steam, then, the thermal efficiency of the boiler, within the range of 73% -79%, and want to obtain specific parameters, reference may be TSGG0002-2010 "energy saving technology Regulatory boiler regulations, "the standard to obtain accurate values. 3. General boiler certificate, if there is gas and coal-fired boilers of points? Coal-fired boilers, which are how many MW? General boiler certificate, there is no gas boilers and coal-fired boilers of points, so at this point, we should have a correct understanding, you can not go wrong. The MW coal-fired boilers, in general, is 0.35-7MW this range.
Technical characteristics: the overall cost of natural gas boiler is half the coal-fired boilers, and operation costs are four times as coal, a ton of steam needs to burn about 80 cubic meters of natural gas, and coal-fired no more than 0.185 kg, the economic accounts will be considered . Select the gas boiler it under certain conditions choice of last resort. As well as on the performance of the gas is better than coal. In principle, they are heat transfer equipment, the difference is that on combustion, complex grate or coal, coal preparation, etc. as well as coal needs, while gas only burner that simple. Use of cleaning gas boiler: boiler after a long run, the inevitable emergence of scale, mainly due to the scale of the problem of corrosion, formation of boiler feed water with hardness components, through subsequent high temperature and pressure continuously concentrated by evaporation in a furnace a series of physical and chemical reactions that ultimately form a hard heating surface, a dense scale, resulting in reduced heat transfer and the effect of corrosion under the scale factors, will result in reduced boiler waterwall furnace heat absorption, furnace outlet temperature of the boiler is increased, so that increased boiler losses. After scaling while reducing the heat transfer within the water wall, water wall tube wall temperature may lead to increased water wall lead to burst pipes, affect the safe operation of the boiler. The first of scale is detrimental boiler, the boiler is the main cause of accidents, the danger main problems: wasting a lot of fuel: Because only one of very few steel thermal conductivity of scale, so when the heating surface fouling will heat blocked, in order to maintain a certain boiler output, it is necessary to increase the temperature of the side of the fire, so that the external radiation and flue gas heat loss. Now it can be used efficient and environmentally non-corrosive cleaning agent gas boiler cleaning, cleaning Fu World Tektronix cleaning agent scale was completely dissolved, the equipment expose the metal tube primary colors, because the reduction of algae and biological sludge fouling effect. At the same time stripping the role of iron oxide and iron oxide Asia, extended gas boiler service life, reduce energy consumption and improve productivity.Free Chat
