anthracite coal fired small volume boiler
Note the use of an industrial anthracite coal fired small volume 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.
Gas anthracite coal fired small volume boiler manufacturers Interpretation: gas boilers have the advantage currently use gas-fired boilers occupy the entire market, gas boiler manufacturers say is largely due to the major outstanding features are used, not only more secure and more environmentally friendly energy reducing waste gas pollution emissions. Whether from material manufacturing has changed are updated on fuel refueling meet the requirements of the State Environmental Protection use. Following on from the industry's leading gas boiler manufacturers to introduce the advantages of gas-fired boiler. 1: save material and more space, said gas boiler manufacturers use as boiler feed gas is no longer used it is possible to save more space ash pile, and does not require a significant amount of ash material can be compared to coal gas more economical use of materials. Gas boiler and fuel delivery equipment and therefore less power consumption is also less compared. 2: use of environmentally friendly energy-saving gas-fired boiler in the use of highly energy-saving and environmental protection has become recognized as a major advantage, gas boiler manufacturers said gas gas-fired boilers used for combustion and therefore not a lot of exhaust gases, thus reducing the pollution of exhaust gas to the space environment, Therefore, more in line with national standards of environmental protection. 3: to reduce labor intensity of reduced staff gas boiler manufacturers decrease stresses on conventional boilers the auxiliary equipment, thus reducing the operating staff, and to reduce the entire operation as compared to when using a gas boiler coal-fired boiler in the secondary feed and coal slag and other processes, and therefore relatively decreased in the course of the labor intensity. 4: movement easier installation as a whole a gas boiler is no longer a conventional coal-fired boilers combination of a plurality of different parts together, so more convenient gas boiler manufacturers said movement of the mounting and can be moved to the fast the use of different venues. To sum up, it is gas-fired boiler gas boiler manufacturers to introduce everyone has four major advantages seen in the actual use of gas-fired boiler appeared to enterprises to bring more convenience of use, and by gas-fired boiler manufacturer preferred brand boiler can improve the efficiency of the work to achieve a gas boiler environmental protection and energy saving technology.
Foshan Gaoming Liu Ling Textile Dyeing and Finishing Co., Ltd. was founded in 2007, enterprises comprehensive strength, advanced processing equipment, detection means perfect, has a complete quality assurance system, the introduction into a large number of advanced production equipment, to ensure that technical standards and products stable to improve the quality of laid a solid foundation, enjoy a high reputation in the industry. Liu Ling Gao textile company twice with my company were to buy a 20 tons of steam and a whole 10 tons of steam condensing steam anthracite coal fired small volume boiler fuel gas for the production of textile dyeing and finishing company. Fang fast with strong comprehensive strength and improve the service system to win the favor of the other side, communication from the initial to the final boiler factory-installed square fast all uphold the customer's perspective to think and observe the service concept, for the sake of clever Liu Ling textile companies according to the company's actual demand for textiles, the development of specific programs.
According to this feature, the blower must be segmented to meet the needs of the combustion. Although the current domestic production of anthracite coal fired small volume boilers are taken into account this feature, using the sub-air room, and is equipped with a damper. However, according to the survey, many units in the actual operation is not performed in accordance with the combustion characteristics of air volume control, the amount of air required for combustion and an actual amount of supply air does not fit very well, so that incomplete combustion loss increases. Therefore, adjustment the combustion in the boiler, the air amount to be supplied to the combustion timely adjusted according to need, to reduce heat loss and improve the thermal efficiency. 3. The use of secondary air. Strengthening of the combustion secondary air stream is very effective, it has the following effects: (1) strengthening the furnace turbulence and mixing of the gas stream in the furnace oxygen and fuel gas are uniformly mixed, so that the chemical loss of incomplete combustion and furnace excess air coefficient is decreased. (2) the secondary air vortex formed in the furnace flue gas, on the one hand to extend the suspension of fine coal particles travel in the furnace increases the residence time of the suspension of fine particles in the furnace, so that there is sufficient time than combustion, incomplete combustion to reduce heat loss; on the other hand due to the separation effect of the vortex gas flow, the coal particles and ash particles thrown back to the furnace, reducing the amount of fly ash escaping the mechanical incomplete combustion to reduce heat loss. (3) the high temperature secondary air in the furnace flue gas is improved fullness, that eliminates dead reduced stagnation zone and improve the utilization of the furnace heating surface. In addition to the secondary air had a marked effect on energy conservation, but on the smoke and dust is also very effective.
