vertical natural gas boiler price for hospital with good service
When the 40 tons SZS series gas and oil fired vertical boiler price for hospital with good service is running, the fuel enters the burner from the external air source, and automatically generates a high temperature flame through the automatic adjustment and automatic ignition function. The front end of the furnace enters the convection heating surface on the upper side of the burnout chamber, and then enters through the upper part of the front smoke box. the second part. The convection heating surface exits the boiler from the rear of the rear smoke box and is vented to the atmosphere. The saturated steam is generated by heating, and the working fluid is output from the main steam valve to the operating system.
Gas-fired steam vertical boiler price for hospital with good service will need to follow those steps: Due to the special nature of dual-use oil and gas boilers, thereby preparing the initial installation and construction from its long-term project to the acceptance stage there will be any problem to pay attention to the need to comply with, what does? Gas-fired steam boiler needs to follow the procedure step by step to complete. In this process, the need to comply with, what does? Boiler installation and construction of oil and gas dual front, first in accordance with the procedures to handle boiler installation approval procedures, pending approval of Quality and Technical Supervision after!
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 vertical boiler price for hospital with good service 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.
