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 natural boiler heat exchanger 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.

About condensing natural boiler heat exchanger: major cities are now facing a wide range of frequent haze weather body, the use of new clean energy - natural gas as a heating source distributed urban heating is very important imperative way around also it has begun to implement a large area of ​​the "coal to gas". And environmental protection and energy conservation must be combined in order to have a long-term mechanism. Natural gas condensing boiler premix gas heating than with traditional gas boiler heating heating costs can be reduced more than 30%, while the low NOx combustion techniques premix can be reduced more than 70% of nitrogen oxide emissions for natural gas efficient use of lower emissions and provides an efficient way.

Is a high efficiency, condensing gas boiler the best choice

Aug 13, 2018 · Condensing boilers produce heat by burning natural gas or propane fuel. The word condensing refers to the fact that these appliances are able to extract heat from the combustion process so efficiently that the flue gases leaving the boiler are at a much lower temperature than in a conventional boiler.

Natural Gas Heating Systems | American Gas Association

Natural Gas Heating Systems. Natural gas heat feels warmer than heat produced by an electric heat pump. Natural gas heat is delivered from forced-air systems at temperatures ranging from 120-140 degrees Fahrenheit. In contrast, the air from an electric heat pump is typically delivered at 85-95 degrees Fahrenheit warm enough to heat a room,
