Dezhou City, Shandong Province, located in northern China, the winter heating livelihood security is the top priority. According to statistics, the main city such as the German city of existing heating eco boilers 63 units, for the protection of the safe operation of the winter heating boiler, the past few days, the German city Bureau of Quality Supervision special equipment inspectors to carry out a comprehensive examination of special law enforcement actions against these heating boilers.

Check the main content around the registration and inspection of boilers, operator's safety if the holder case posts, etc to focus your heating boiler operating conditions, in particular the various safety accessories and safety devices especially by the attention of inspectors. By the inspection activities, it may be within the control range as much as possible, to ensure the safe use of heating boilers.

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 eco boilers 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.

When customers need to buy oil and gas eco boilerss, they need to know the boiler capacity that they need. Because the boiler will consume a lot of fuel during operation, the boiler capacity will cause unnecessary losses and increase the boiler cost.

Gaz than steam eco boilers should be how to calculate? Q: ratio of gas steam boiler gaz simple algorithm is multiplied by the calorific value of coal and boiler efficiency is calculated by dividing this simple assumption does not heat to the steam boiler efficiency of 80%, coal calorific value 5500, if the amount of steam produced a ton of coal can be calculated as follows * 0.8 = 5500/600 = 7.3, ie: gaz ratio of 7.3 can be calculated simply, is this right? A: According to your argument: the amount of steam a ton of coal produced, commonly referred to as the evaporation rate of the fuel, commonly known as steam coal ratio. The calculation formula is: base received low calorific value of coal is then divided by multiplying the thermal efficiency of the boiler (steam heat feedwater minus heat). You said above is correct.
