gas natural boiler heat exchanger
Second, grasp the "coal to gas," the key link.
1, removal of the original coal-fired boiler slag machine, coal hopper, coal equipment, chain grate, gearbox and so on.
2, by calculating the heat transfer in the furnace, the furnace geometry is determined, the center position of the furnace flame. Re-casting furnace, the furnace using the refractory castable
Fast one side condensing natural boiler heat exchanger steam condensate integrally advanced technology, with high efficiency, appearance, durable, cost savings, reduced noise, low nitrogen environmental advantages; self-developed by use of flue gas condenser waste heat boiler greatly increased thermal efficiency, while reducing emissions of harmful substances, can save a lot of fuel, compared with ordinary boilers, the average annual fuel cost savings of several million. Fast and well-equipped boiler unique cloud service 3.0 system, through remote monitoring of boiler operation, all-round ensure the safe operation of boiler.
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.
