Primary air tube blockage is what causes? How to prevent? Reason: 1) blocked or coked-burner fire nozzle inlet is blocked portion of small oil gun and other debris. 2) too many impurities coal, powder machine speed is too high, the pulverized coal and primary air speed too low. 3) powder machine speed is too high, too much under the powder without timely blown away. 4) a low pressure (throttle open or not to open too small), can not take away meal. Precautions: 1) to the powder and the rotational speed of the unit load and adjust relevant primary pressure according to the powder not more than 700 rpm rotation speed, a wind speed of each holding 25 ~ 30m / s, the mixed primary air temperature was controlled at 180 to 250 ℃, a pressure depending on the load, depending on coal, in the range 2.5 ~ 3.8kPa. 2) find a wind speed is too low, the primary air temperature is lower than the normal value should be to lower the rotation speed corresponding to the normal to the powder of a primary air temperature and wind speed. 3) open, gas steam brushless dc motor for boilers from japan tank should be fully cut-off torch powder, the powder in the tube is blown accumulated powder. 4) Fire mouth clogged or coked should try to remove. What causes large vibrations induced draft fan? 1) motor bearings in oil, resulting in large vibration and bearing wear; 2) even when the shaft is mounted on the center not good; 3) induced draft fan stall surge; 4) anchor bolt loosening induced draft fan; 5) blade fouling or wear ,lost balance.
Battle to win the blue sky, is the major decisions and plans to make a big party in the nineteenth, and is for building a moderately prosperous society, to improve the quality of life of citizens and establish a beautiful China's development goals. To fully implement the nineteen spirit, promote the governance of air pollution intensity and improve the living quality of the environment, this year March 8, Zhengzhou Municipal Party Committee General Office, Zhengzhou Municipal People's Government Office issued the 2018 air pollution control program and the corresponding subsidy policy, the implementation of low-nitrogen gas brushless dc motor for boilers from japan retrofit demonstration project, as follows:
Before the end of September 2018, the city's more than 20 tons of steam (with), and the urban areas more than 4 tons of steam (with) the completion of gas-fired low-nitrogen transformation project demonstration projects, nitrogen oxides emission concentration is not higher than 30 mg / cubic meter, City level financial awards complement carried out in accordance with the 40% investment in equipment;
Before the end of September 2018, the city's more than 4 tons of steam (with), and the urban areas more than 2 tons of steam (including) low nitrogen gas boiler reconstruction project completed demonstration projects, nitrogen oxides emission concentration is not higher than 30 mg / cubic meter, City level financial awards complement carried out according to 30% of equipment investment;
Before the end of April 2019, the city completed all gas-fired low-nitrogen transformation, nitrogen oxides emission concentration is not higher than 30 mg / cubic meter, the municipal finances awards complement of 15% investment in equipment.
8 ton condensing fuel gas-fired brushless dc motor for boilers from japans in Russia
ZG boiler re-export project—a full set of 8 tons of condensing fuel gas-fired boilers was exported to St. Petersburg, Russia. As the economic power of Russia, St. Petersburg takes industry as the main development point, and is a highly developed international city of science, technology and industry. Therefore, the selection requirements for production equipment are very high. The ZG boiler oil and gas boilers feature the internationally popular classic “all-wet-back three-return” design structure, FRG flue gas recirculation, condensation prevention and control, and other special technical advantages to enable Russian customers to successfully sign a complete set of 8 tons of WNS with ZG boiler within a week. Type saturated steam boiler contract, the fuel is natural gas and diesel. In addition, based on Europe's strict boiler emission standards, ZG boiler has configured pure Italian imported burners for customers.
The difference between oil-fired brushless dc motor for boilers from japan and gas boiler difference between oil-fired boiler fuel oil boiler and gas boiler is fuel (such as diesel, oil, kerosene, etc.), fuel gas-fired boiler to gas (such as natural gas, city gas, methane, etc.), depending on the boiler What fuel burning device called a burner, gas burner configuration called boiler gas boiler, oil boiler burner configuration called oil-fired boiler, oil-fired boiler and gas boiler difference lies in the use of fuel burners burn anything.
