excellent quality coal boiler

Note the use of an industrial excellent quality coal 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.

Factors industrial excellent quality coal boiler energy-intensive factors which have high energy consumption of industrial boilers which 1, energy consumption is low management level industrial boiler is too large, there are currently a lot of long-term business. On the one hand understanding of the enterprise energy conservation boiler is still not sufficient, on the other hand the energy management level is still at a low level, and even some companies even the most basic measuring instruments are not equipped. In order to reduce operating costs, many companies have to buy the old boiler use, lack of components purchased fuel means of inspection. Even in the case of raw coal screening is not performed, it is directly put into production use, it is difficult to ensure full combustion of coal. Not only the thermal efficiency is low, but also resulted in a waste of fuel. 2, heat recovery is poor combustion is incomplete, the situation is the high rate of heat loss is extremely common in industrial boilers used in the process, saving the main parameters of the boiler will be exceeded. Economizer function is to heat energy recovered, but in actual use, heat recovery efficiency is very low. In this case, do not use a lot of boiler economizer direct altogether, inevitably produce exhaust gas temperature is too high. Meanwhile, return the device and steam condensate recovery, it has not been fully appreciated and better use, some are put to use in the boiler after installation, and did not take appropriate measures to deal with poor recycling effect. 3, lack of effective supervision of the level of energy service work, depends largely on the level of experience and technical personnel. But in practical terms, due to the lack of technical personnel, resulting in the energy service work at the level of the low. Various enterprises produced energy-saving products with high imitation, coupled with the lack of effective supervision of energy-saving measures, resulting in the entire market of energy-saving products more confusing. The effect of not only energy-saving effect is not ideal, and to transform the poor, the performance of energy-saving products remains to be greatly improved. Market confusion, vicious competition phenomenon has not been fundamentally curbed.

Electric excellent quality coal boiler advantages: electric boiler because of its low consumption, convenient, more and more people are welcome, so that people no longer have problems because of coal, causing a lot of unnecessary trouble, electric boilers do not understand what advantage allows electric boiler You use the electric boiler to join the ranks of it? Below these advantages, it must give you enough reason to use an electric boiler.
