0 7t h coal burning boiler
ZG biomass fired 0 7t h coal burning boiler can be divided into chain grate boiler (also called travelling grate boiler) and CFB boiler. And our power plant boiler can use fuel like biomass and coal. Our biomass fired chain grate boiler can be divided into DZL, SZL and corner tube type.
Note the use of an industrial 0 7t h coal burning boiler fan which 1, strengthen the operation and management, ban illegal operation. Industrial boiler drum fan up and running, there must be strict rules. The induced draft fan starts to be unloaded, non-load starting, particularly when the boiler stoked, flue gas temperature is too low, such as the induced draft fan starts with load (i.e., open the blower inlet damper or fully open), a current will start increased a lot, and start-up time is too long, the fan motor can overheat, overloading is likely to burn out; when the boiler (particularly pulverized coal) Jan-fire operation, pay attention to drums, fan's opening sequence, can not be reversed. I.e., first open fan, run for 10 minutes, and to exclude the furnace flue fouling or flammable gases, before the blower starts. If the first open blower, the induced draft fan, so that both the induced draft fan load is increased, so that the induced draft fan motor overheating burned, and the furnace may lead to explosion. 2, industrial boiler flue gas dust removal blowers take measures to regularly clean the flue, induced draft fan to improve the working environment. Dust removal equipment units to strengthen the dust removal operation and management, improve the efficiency of dust removal; no dust removal equipment units to time quantitative dosing into the boiler furnace special cleaning agents, and timely removal of fouling of the flue, the flue avoid clogging, the impeller damage accidents. 3, the impeller blade surface hardening treatment to improve the wear resistance of the blade. Since the large fan boiler drum conveying high temperature flue gas is about 200 ℃, the flue gas contains large amounts of fly ash, SO2 and other corrosive gases, badly worn fan blades, fan output prone to drop, vibration, such as rupture of the blade. Therefore, to deal with a serious face or wear parts of welding blades to improve the wear resistance of the blade. Use DC welder welding, arc welding using manual method using a dedicated fan hardfacing strip (e.g., wear No. 1, Mo-Cr-B carbide electrode wear, etc.), and the electrode wear in 300 ~ 350 ℃ drying 1 hour use. Before welding, the surface of the blade should be fouling, rust cleaned, preheated to 100 deg.] C, with a small current, low voltage, temperature and speed, short arc welding symmetry. Practice has proved that, after surfacing treated leaves, wear resistance greatly improved, not only changed the fan impeller often wear, but also laid a good foundation for the safe operation of the fan. 4, insist on Boiler Fan periodic overhaul, maintenance of strict quality control. Industrial boiler drum Fan to be overhauled on a regular basis. The elimination before the accident hidden danger in the bud, to overhaul a comprehensive, thorough, carefully check the wear, the impeller shaft and impeller balanced operation, with or without internal connections loose, collision, inlet baffle switch is flexible and bearing lubrication and cooling Happening.
The United States is our national enterprise, one of the world's top 500, with very bright glory on the world stage. US air-conditioning as a subsidiary branch, with a very large market competitiveness. 2016, Hubei US air-conditioning due to market demand to expand production lines, need to purchase steam 0 7t h coal burning boiler to provide energy support for the new production line. After the boiler industry for a number of enterprises contrast, is determined to cooperate with the fast boiler, buy a whole 10 tons of steam condensing gas steam boiler (WNS10-1.25-Y.Q).
DZL series bagasses steam 0 7t h coal burning boiler in distillery, its capacity is from 2 to 10 ton. This boiler can be used in smaller distillery. DZL series boiler can burn coal fuel, biomass fuel, and mixed fuels, so does SZL series and DHL series. DZL series chain grate boiler, its features like Inverted "α" arch furnace technology, combustion efficiency improved. It is a kind of fire tube boiler, automatic operation system, packaged boiler.
