Through estimation: If the exhaust gas temperature of 150 ℃, when the excess air ratio from 1.5 to 3.0 cases, the combustion is generally bituminous coal, anthracite 8t coal boiler low price industrial jordans, heat losses from about 5% to 10%, reducing the thermal efficiency of the boiler nearly 5 percentage points. While the chain grate boiler excess air ratio was mainly due to leakage caused by the grate, but also accounted for a large proportion of the furnace leakage, strict plugging wind, to improve boiler thermal efficiency, reduce coal consumption, save energy resources it is very significant. Before plugging the wind, the first thing leakage test boiler.

How to choose a reasonable price brand of industrial 8t coal boiler low price industrial jordans: Fuel How to choose a reasonable price brand of industrial boilers, gas boilers burning, good insulation properties, clean and green, the boiler thermal efficiency advantages, is currently popular on the market A boiler , in addition to the gas boiler has its own characteristics, the full implementation of the national coal policy to further promote gas-fired boiler coal-fired boiler to become the user's preferred furnace, gas boiler market demand continues to grow. There are many brands on the market boilers, boiler quality is not uniform. For users, how to choose the right brand of industrial boilers price is very important. How to choose the affordable brand of industrial boilers, we all know that smoke respirable particulate matter is the culprit, but in fact, another reason - nitrogen oxides can not be ignored. Coal project promotion, gas boilers ownership will continue to increase. Coal combustion gas may reduce the pressure of the coal, to reduce the concentration of airborne particulate matter, nitrogen oxides, but also an important reason for the smoke, which generates an important condition is a high temperature. Gas boiler for heating and the heating temperature needs.

It provides fast side of 8t coal boiler low price industrial jordan equipment, installation and commissioning after all normal, we immediately put into use, the hotel did not delay the normal heating. Meanwhile boiler capacity, energy efficient, fully able to meet the needs of heating and bathing water in our hotel rooms. --customer feedback

Note the use of an industrial 8t coal boiler low price industrial jordan 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.
