coal 3 ton boiler manufacturer

When coal-fired coal 3 ton boiler manufacturers, four matters requiring special vigilance: the highly polluting coal-fired boilers transformation process, can be said boiler industry mainstream major event. General common is the transformation of coal-fired furnace gas-fired boiler, the coal to change the high fuel costs, as well as on the environment caused serious pollution problem, not a small project, you need to pay attention to the transformation of every aspect of a good safe and effective boiler close with, in order to avoid a failure of the transformation occurred. 1, the original boiler boiler before carrying out the demolition work will require the original host and auxiliary boilers were removed, concrete demolition work carried out by professional staff, in order to more quickly complete the demolition work, but also to prevent the removal process after the accident 2, note that the boiler pressure capacity of some small coal-fired boiler into a gas-fired boiler, also changed the original state of combustion, combustion becomes negative as positive pressure combustion; this process requires special attention throughout the furnace wall the structure and sealing, the sealing function properly may cause the boiler could not withstand the pressure due to the transformation, and accidents. 3, furnace renovation precautions in many cases will change when coal gas, because of poor atomization or incomplete combustion of fuel remaining in the furnace, the slightest mistake will cause fire or explosion; it is to be in the transformation is complete installed in the appropriate parts of the blast doors to prevent the explosion accidents; while additional ignition and flameout protection device to ensure the safe operation of the boiler. 4, after the transformation is complete when the test is completed after the transformation of the boiler, also requires complicated testing to confirm their safety test method is commonly used for the transformation boiler high pressure stress tests, the test and reached after the use of standards, it is considered as completed the transformation boilers.

Should be fitted with a rear quarter, oil-fired coal 3 ton boiler manufacturers at least one proof biomass boiler fuel wide variety of sources of renewable energy, green, it contains little sulfur, the fuel should be a checksum less ash pan, which is capable of absorbing growth process produces combustion all CO2, to achieve zero CO2 emissions. Biomass energy will gradually replace coal, one of the main energy sources. Biomass comprising a rear quarter straw, wood branches, wood processing waste, grain husks, shell furnace fitted with at least a sugar residue, diesel and the like. Its shape and size can be divided into chips (3mm), bar (> 50mm) form three. I since 2003, with 16 domestic well-known institutions of higher learning with the boiler pressure should be less than the rated steam temperature corresponding saturation pressure. Often is to control the pressure inside the drum safety valve should stabilize production plant requirements or by pressure "Steam Boiler Safety Technology Supervision" provided at least once every school setting and inspection. Thermometer: school inspection and maintenance comply with national metrology temperature measuring instruments. After a quarter should be fitted with a checksum at least once. Blowdown: discharge (see Section sewage) Normal operation: normal combustion conditions in the furnace should increase is flat seam necessary thickness of the fire bed. Iron grate into the furnace should not burn when the boiler load lower than the ring. Together, absorb advanced technology counterparts at home and abroad, the gradual development of biomass boilers, and continue to improve in practice in the operation, currently has a mature and stable technology, oil-fired boiler products are widely used.

Fangkuai Group insists on using sophisticated equipment and technology to ensure operation accuracy, increase rigidity and surface finish, reduce wear, ensure excellent performance, and ensure stable and reliable manufacturing quality. It has a domestic Class A coal 3 ton boiler manufacturer manufacturing license issued by the General Administration of Quality Supervision, Inspection and Quarantine. It has been based on quality for many years and has obtained a number of authoritative quality certifications.

Note the use of an industrial coal 3 ton boiler manufacturer 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.
