chimney liner for gas boiler

Problems coal chimney liner for 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.

Chinese wine culture has a long history, wine blend. In the process of making wine, almost all wine prices are inseparable from the brewing process steam, we can say the stability and quality of steam purity of the wine production plays a decisive role. Lefort Wine has been committed to producing high-quality wine products, December 2016 No. 1, Lefort wine and I signed a one 4 tons of steam condensing steam chimney liner for boilers, the company continues to provide high-quality wine work steam.

Increase productivity chimney liner for boiler system must first be optimized for verification, including the entire steam system for a complete analysis, and focus on some of the energy waste places. Via check can often find opportunities to save energy, increase productivity, and environmental protection have a positive contribution of. Check includes a steam generation, distribution, use and condensate recovery. The main steam waste requiring special attention place: exhaust gas boiler: boiler efficiency emissions system the most important indicators, the loss of energy is the most important place. Combustion air: general air enters the combustion furnace of the genus room temperature, require a lot of heating energy, i.e., the most commonly used power saving mode using a high temperature exhaust gas to preheat the combustion air of boiler, boiler efficiency can be significantly improved. The fuel / air ratio: Proper oil / gas mixture can only complete combustion, if the lack of air, combustion is incomplete, not only smoky pollution, environmental protests caused nearby residents, and easy carbonized grease gun and boiler heating tubes affect performance. If excess air is formed wasted energy, reducing boiler efficiency. Via the oxygen content of the tail gas can appropriately adjust the oil / gas ratio. Oil-fired boiler exhaust gas which content 3%, i.e., the excess air of about 15%, as the standard combustion control.

As fast chimney liner for boiler manufacturer specialized in the production of gas boilers and electric boilers, it has gone through 20 years of development history. The energy-producing gas boiler and then fully welded to the pre-expansion, and finally Expansion technology, both to prevent corrosion of the tube gap, but also enhance the welding strength; threaded pipe using a high heat transfer coefficient, heat strengthening effect on the spread , reduce exhaust gas temperature and improve the thermal efficiency of the boiler. With industry-leading gas boiler products and perfect after-sales service, fast boiler boiler by many users of gas acceptance and trust.
