horizontal fire tube 2 ton coal boiler

Coal-fired horizontal fire tube 2 ton coal boilers have been abandoned prospects for environmental protection boiler can be expected by the end of 2014, the city authorities will be coal-fired boiler, tea bath furnace conduct a comprehensive investigation, the completion of the city's coal-fired boiler, tea bath furnace investigation to establish the investigation file. By the end of 2015, the central heating, coal to gas, coal to electricity projects, urban built-up area of ​​Dazhou out of 10 tons of steam per hour of coal-fired boilers, tea bath furnace, a ban on new coal-fired boilers; counties (cities ) no new 10 tons of steam per hour of coal-fired boilers. By the end of 2017, within the city's jurisdiction phasing out 10 tons of steam per hour of coal-fired boilers. In other parts of the supply pipe network covering less than, change electricity, new energy or clean coal, promote the use of environmentally friendly energy efficient boiler systems. Chemical, paper, printing and dyeing, pharmaceutical and other business gathering area, by focusing on the construction of cogeneration units dispersed phase out coal-fired boilers. 2014 Pudong District, will complete the transformation of 160 coal-fired boilers Recently, the district held a coal-fired (heavy oil) boiler will work to promote clean energy alternatives, summed up the situation in our region to develop clean energy alternatives work in 2013, the deployment of the main work this year. Meeting was informed that, in 2014, the towns (industrial area), belonged to the company will accelerate the region natural gas pipeline network planning, heating network planning revision to develop industrial parks, to ensure that policies and funding in place, and take a variety of measures to ensure the successful completion of 160 units / sets of coal-fired boiler with 17 units / sets of clean energy alternative industrial furnace work this year. In 2013, our region continues to improve project access threshold, eliminate backward production capacity a total of 44, 159 to complete the clean energy alternative.

Note the use of an industrial horizontal fire tube 2 ton coal 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.

The horizontal fire tube 2 ton coal boiler induced draft fan is the equipment that removes the flue gas from the boiler, this kind of machinery is actually the same in the working principle, but the impeller of the ventilator is installed in reverse, then the air will be transported according to the opposite direction. Gas such as carbon monoxide will be produced by incomplete combustion of coal in the process of boiler operation. If these gases are not eliminated in time, the efficiency of boiler will be affected.

Condensing a portion of the air preheater and use of double combination economizer design. Internal economizer heat exchanger elements using the new technology - the wings of the tube instead of finned tubes, a five-fold increase in heat transfer area at the same volume, latent heat of vaporization of the portion of the flue gas is sufficiently absorbed, effective utilization of the fuel energy, energy saving at the same time enhance the efficiency of the use of the horizontal fire tube 2 ton coal boiler. Air preheater is further absorbed by the air and the flue gas convection heat latent heat of flue gas, and the air heated by the air preheater is connected directly into the burner tube, providing warm air for the fuel, thus improving combustion efficiency. This exhibition brings Chinese fast "Euromonitor" series boilers attracted a large number of customers, to give customers unlimited. Here, fast Boiler staff wish the exhibition every success.
