A correct steam poultry boiler daily rate up shutdown: 1, the steam boiler is not used to determine, fireman and support staff to coordinate Division, before proceeding shutdown operation. 2, to reduce fuel (coal), and then reducing the amount of wind, until after the load falls to zero, closing the main valve and stop the air blowing, the wind is stopped after 5 minutes. 3, the shutter closing the flue, each door seal, manholes. 4, the boiler flame, when the vapor pressure exceeds the working pressure, exhaust valves should be opened or add water to the boiler and the blowdown, but should not significantly cooled boiler. 5, boiler pressure is not reduced to zero, to maintain the normal water level, the operator may not leave their posts until the pressure to zero, then make sure all links are correct before they show proper steam boiler shutdown.
Gas pressure Analysis of Gas-fired Steam Boiler? The gas-fired steam poultry boiler daily rate up has some related factors in the parameter of gas pressure, and it is also related to other parameters, for example, it is proportional to the evaporation of the boiler, and related to the size of the burner. Therefore, in the determination of specific values, but also depends on the actual situation, it will be decided. However, in general, gas-fired steam boilers of less than 0.5 tons, gas pressure is required for about 3000Pa, more than 1 ton of gas-fired steam boilers, gas pressure is required about 5000Pa.
January 16, Harbin Municipal Environmental Protection Bureau Director of the atmosphere and noise pollution control at the public hall, Li Bin, said: "Harbin problem-oriented, focused on solving the coal pollution environmental air quality, autumn and winter of straw burning pollution." By a wide range of governance, 2018, Harbin has made in terms of ambient air quality improvement remarkable results, the standard number of days 310 days, an increase of 40 days, for the introduction of new environmental quality standards since the best of the year.
Prior to 2017, the total removal of Harbin urban built-up area of small boilers range of nearly 3,000. 2017, Harbin started the largest in the history of the elimination of small-scale boilers battle, tear down 9 district built-up areas and industrial parks within a small boiler 2074 units. 2018, further expanded the phase-out range, expanded from 9 Zone has outside built-up areas, where the built-up area in District 9 out of 10 tons of steam per hour of coal-fired boilers to achieve foundation "clear" on the hour and eliminated more than 10 tons of steam coal-fired boilers 99 units, out of the city a total of 1191 units. The results accumulated over the years, significantly reducing the use of coal, reduce emissions of pollutants.
According to reports, in the fall and winter seasons, Harbin straw Jinshao pay close attention to the work to implement the five grids responsibility, building straw Jinshao 24-hour duty system inspections, inspection teams at all levels of uninterrupted inspection. In addition, Harbin has also implemented emission standards of air pollutants, vehicle control, open-air barbecue ban, dust management, especially in heavy weather pollution contingency timely warning, take active control measures played a role in the down-clipping. Through various management, air quality has been greatly improved.
Type dust precipitator maintenance standards of large poultry boiler daily rate ups, such as XZD / G a cyclone type 6, the filter cylinder by the main flat top plate and bottom plate mounted dimensional shape. Maintenance is mainly during use, wear resistant coating wears off, the outer surface of the repair paint chips oxide; ash in the ash box sealing cap to check for updates to avoid leakage affect the collection efficiency. After typically three to five years in operation, should check the wear of a wear resistant coating shedding, if more than half the original thickness of the wear, should be re-applied, if partial loss should be Buxiu. Filter cone portion, should always check the insulation case, and should be found to fall patch.Free Chat
