how to choose gas fired boiler cost

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 how to choose fired boiler cost 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 the 40 tons SZS series gas and oil fired how to choose fired boiler cost 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.

We produce steam how to choose fired boiler cost is a very important part of the device, this provides a quick way to our gas steam boiler, after use, we found an excellent energy-saving effect boilers, flue gas discharge temperature is lower than the previous boiler equipment many, in line with national environmental provisions of the boiler equipment. --customer feedback

A number of national influence energy consumption steam how to choose fired boiler cost coal to natural gas has been vigorous work, it should be transported steam boiler, very big eliminate the dust pollution, discharge of toxic gases and secondly nitric oxide, also got curb. Energy consumption is crucial mark measuring steam boiler, a good start and that is that work together to explore under the influence of a number of cases the energy consumption of steam boilers. Through the investigation of the persons concerned, the loss of heat from steam boilers bear the main two areas: combustion air-fuel ratio does not smoke emissions standards-related heat loss. Reduction of heat loss will install smoke emission in the flue gas heat recovery steam boiler terminal fitting, or should be transported more leading type condensation recovery boiler. Combustion air-fuel ratio standard fault summary: a conventional steam boiler burner ejector type, formed air-fuel ratio can not occur motorized adjustment. Some of the steam boiler with a mechanical blower burner, causing air-fuel ratio standard there are several aspects later: the main air-fuel ratio standard case encompass fall into two categories: air flow when exceeded, there will be an endless excess cold heat transfer, resulting in high energy cost of steam boilers, steam boilers reduced energy consumption; when the airflow is not enough, will have not exactly lit, the energy consumption caused by steam boiler weakened.
