Commercial Cheap 20t Gas Boiler

In accordance with article 1.2 13.3.6 to 13.3.8 "commercial cheap 20t boiler design specifications" (GB50041-92): gas-fired boiler provided in the other buildings should be not less than 3 times the amount of ventilation, ventilation hour It does not include the amount of combustion air volume. Dangerous operating room and the like between the gas regulator, the amount of ventilation per hour, should be less than 3 times, when not meet the requirements natural ventilation, mechanical ventilation should be provided, and should be less than 8 air changes per hour accident ventilation times. Fuel pump and reservoir 45 ℃ flash point less than the underground tank of combustible oil, except that natural ventilation, the fuel pump mechanical ventilation 10 air changes per hour should times, six times per hour ventilation should depot mechanical ventilation. The above three are in each room in order to ensure exclusion of air and flammable hydrocarbon disposed a predetermined minimum ventilation rate.

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 commercial cheap 20t boiler 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.

Oil and gas commercial cheap 20t boilers are a very common type of boiler. Long ago, natural gas, oil and other fuels were used in boilers. In industrial production, the application of boilers is always indispensable. In today's industrially developed society, boilers are a product with a large demand market. There are numerous manufacturers of large and small boilers. According to the boiler market situation, there are many oil and gas boiler manufacturers.

In late May 2018, Hedong District, Tianjin Environmental Protection Bureau, the District Construction Committee, District Bureau for approval jointly held low nitrogen gas commercial cheap 20t boiler reconstruction work will push for the Municipal Environmental Protection Bureau atmosphere at the meeting of May 18 Air pollution control work in progress briefing involves the transformation of low nitrogen gas boiler, convey the contents of the meeting and introduced the progress of work and experience low nitrogen gas boiler reconstruction of other counties.

Clear four key tasks meeting: First, all gas boiler units must be in accordance with the time node, complete technical solutions before the end of May to develop and expert appraisal work;

Second, according to the requirements of the minutes of the 49th executive meeting of the district government, the units shall, not later project work next week to start the project, and accelerating project bidding, project construction to ensure completion before the end of September;

Third, the units should seriously accordance with the "Municipal Environmental Protection Bureau of Finance on the issuance of Tianjin Gas boiler low nitrogen fixed subsidy reconstruction project implementation approach" (environmentally friendly gas-chun [2017] No. 171), "on the issuance of Tianjin Municipal Environmental Protection Bureau letter fixed subsidy acceptance requirements of low nitrogen gas boiler reconstruction project "(Tianjin environmental Protection memo No. [2017] 406) and" Municipal environmental Protection Bureau Municipal market supervision Commission letter of relevant work requirements transformation of low nitrogen gas boiler "(Jin Han [green gas the relevant procedures 2018] No. 92) requirements, preparing project application and acceptance, with particular attention to security issues in the process of transformation of the project, to ensure that emissions meet the standard requirements after the transformation;
