Cofiring biomass in coal fired high efficiency coal fired wet back boiler for chemical

Cofiring biomass in a coal fired boiler is like a cart drawn by a horse and a mule. What are the advantages? It took millions of years for decaying organic matter to form into coal. Biomass on the other hand is organic matter that is only a few days old. The composition and characteristics of biomass is different from coal and makes cofiring biomass and coal difficult.

Note the use of an industrial high efficiency coal fired wet back boiler for chemical 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.

Instead of gas-fired high efficiency coal fired wet back boiler for chemical coal-fired boilers has become an inevitable trend of more and more common as the use of gas, China's energy structure has undergone tremendous changes. In the future for a long period of time, gas and coal is still the main source of energy, how to weigh the severity of it in small series for everyone here today about the analysis and comparison:? Although there are many drawbacks of coal-fired boilers, but in the national economic development has an irreplaceable role, he plays an important role in the past for a long time. Because all the advantages of gas-fired boiler, will become a major force in the development of national energy policy boiler. Instead of gas-fired boiler coal-fired boilers has become an inevitable trend. Coal-fired boilers are in a very long time the main products of heating, but there are many drawbacks: such as low thermal efficiency, energy waste, due to the high sulfur content coal, to atmospheric pollution. In recent years, the contradiction between supply and demand of energy and environmental pollution have become increasingly prominent. Compared with coal and gas, is one of the most clean fuel, he combustion, high thermal efficiency, low air pollution, good environmental performance.
