We recommend that, before you determine the horizontal fire tube boiler, first do an assessment of the transformation. Is it worth the stove transformation, transformation is the cost, or cost-effective renewal is the transformation conversion, the user issues are to be considered. How much of the cost of the boiler from coal to gas in the end what is it? How to calculate it? 1, the first to do right now with a valuation of coal-fired boilers, such as what year to buy used, the service life of the furnace is how long, how long now use, how long can also be used to purchase equipment cost, how boiler loss and so on. 2, secondly, to determine the transformation of the specific components, such as the burner is sure to transformation, since the coal combustion mode has changed. So to choose what kind of burner, the price of domestic and imported is different. 3. When ready to do a good job, these statistics up, and then do a calculation, can be drawn transformation costs and expenses.
It works with organic heat carrier horizontal fire tube boiler to be emphasized three points: the boiler organic heat carrier boiler, all these A boiler, whether familiar with and understand it? Why we raise this issue, and its main purpose is to be drawn article content, and let everyone be ready to targeted learning, to improve learning efficiency, enhance learning, so, to make their own benefit. Organic heat boiler, which can also be called oil boiler, the working fluid because the heat transfer on the boiler, or heat carrier, for the heat conducting oil, thereby to achieve a thermal energy conversion device. Further, the operating characteristics thereof, is a low pressure high-temperature operating characteristics. 1. The working principle of the major classes of organic heat boiler organic heat boiler, which is specifically as follows: coal, oil and gas and other combustible materials such as a combustible fuel, and thermal oil as a heat carrier, by circulating pump the liquid forced circulation, heat transfer is performed, so as to achieve the intended purpose and effect. The main types of organic heat carrier boiler, if divided by fuel, then the organic heat carrier for electric boilers, coal-fired organic heat carrier boiler, oil boiler organic heat carrier boilers, gas and other such organic heat carrier.
Problems coal horizontal fire tube boiler gas boiler gas coal problems are: 1, more coal ash, 2, unevenness of coal particles, 3, coal contains a large amount of impurities, 4, a lower heating value of coal, 5 when combustion is not easy to ignite fire, 6, coal moisture content uncertain. 7, does not burn coal, slag high carbon content. In general, use is preferably designed coal boiler design coal or coal close, in order to ensure stable combustion. In recent years due to the growing tension surrounding the coal supply, coal supply has become diversified, coal quality is very different than before coal, have a great impact on the stability of the boiler combustion and normal heating operation. Impact of coal combustion boiler stable for: calorific value of coal is coal reflects an important indicator of good or bad, when the low calorific value of coal to a certain value, will not only affect the incomplete combustion instability and can lead boiler flameout, the outlet temperature of the boiler is difficult to compliance, affecting the normal operation. Volatile combustion and can be deposited at lower temperatures, as the combustion heat, the temperature rapidly increased coke particles, provide an extremely favorable conditions for ignition and combustion, volatiles further increased coke deposition and internal voids and the external reaction area, will help improve the speed of burning coke. Thus, the greater the content of volatile, nonflammable, the less fixed carbon in the coal component, the easier coal burning ember, devolatilization of many voids, increases the surface area of the reaction, the combustion reaction is accelerated. When the volatile content is reduced, pulverized coal ignition temperature significantly increased, the hot increases, difficult fire, ignition time required becomes longer, the combustion stability is reduced, shifting the center of the flame, furnace absorbed radiation heating surface reduce heat, increase the heat absorption of the convection heating surface, the rear exhaust temperature, exhaust loss increases.
