fire tube small coal fired boiler manufacturer

Environmentally friendly gas-fired fire tube small coal fired boiler manufacturer combustion gas combustion five characteristics: In recent years, many cities frequently haze, caused widespread concern and heated debate. China is in the energy structure adjustment period, the task is urgent, the situation is very grim. Energy saving boiler gas boiler is the time to show their talents, its good energy efficiency and excellent environmental capacity, more and more enterprises of all ages. Here we analyze the characteristics of its advantages from the combustion of gaseous fuel. The fuel gas is a highly efficient, clean energy, its relatively low ignition temperature, the flame may spread rapidly to all parts of the furnace, the rapid combustion, facilitate gas, mixed with the combustion process is automatic, has the following characteristics: (1 ) virtually zero pollution combustion characteristics coupled with substantially does not produce ash, nitrogen content and sulfur content should be much lower compared to the fuel oil and coal, flue dust contained in the combustion rarely, very help protect the environment, essentially non-polluting combustion, even the most stringent environmental requirements of the region also ease of use, while gas fuel delivery pipes are based, will not produce ash, during transportation and storage leakage of harmful gases, dust and noise pollution does not occur. (2) facilitate adjustment of combustion. Transport pathways is the fuel gas conduit, through the valve, damper adjusted accordingly, adjust the air consumption can be achieved quickly adapt load changes, low oxygen combustion can be realized, thereby improving the thermal efficiency of the boiler. (3) Good job. Compared with the fuel oil, fuel gas from the transport duct, direct supply, eliminating the sump, fuel tanks and other household members. In particular compared to the heavy oil fuel, eliminating the need for heating, thermal insulation and other aspects. Gas system is relatively simple, the operation is relatively easy to manage, easy to automate. (4) easy to adjust the amount of heat. When LPG combustion, part of the air is added, to avoid the part of both the explosive range, you can adjust the amount of heat. (5) There are some disadvantages gas fuel, when mixed with a certain proportion of air, it will form an explosive gas, most of the fuel and the gas composition to humans or animals asphyxia toxic, so the security is very high. Boiler attaches great importance to the security of energy saving gas boiler in the production, testing process strictly guard the quality, as long as the practices in use, accidents will not happen.

Note the use of an industrial fire tube small coal fired 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.
