water tube fire tube boiler explosion

Solution 1, due to the decrease of the atmospheric pressure, the fuel combustion speed slower burn time becomes longer, the carbon dioxide dissociation rate increases, increasing the chemical incomplete combustion heat loss. Solution to this problem is to appropriately increase the furnace volume, increased fuel residence time in the furnace. 2, no influence of the atmospheric pressure drop pairs exiled heat transfer coefficient of the heating surface, but decreases of Flame cause radiation heat transfer coefficient is reduced, so that the overall heat transfer coefficient is reduced. While reducing the radiation heat transfer coefficient caused by furnace exit gas temperature rise increases the convective heat transfer temperature difference, but to ensure that the exhaust gas temperature rises to a certain extent without excessive levels of convection heating surface area of ​​the water tube fire tube boiler explosion should be appropriate increase. 3, low-altitude wind pressure effect on the smoke characteristics of a large gas-fired boilers, gas boilers running in the plateau region, the burner selection must be a revision in its air volume and pressure, ensure that the output power and boiler burner output.

Heat plays a huge role in food factories. Heat is an effective means of sterilization. Heat can heat food, ripen it, or reach the level of production. The generation of heat requires the use of a steam water tube fire tube boiler explosion or a hot water boiler. Concerning food factory boiler is mainly used for distillation, extraction, disinfection, drying and ripening in the food processing.

Details on the type of the water tube fire tube boiler explosion: the boiler is a boiler and the furnace consisting of an energy converter which is to use thermal energy released by combustion of fuel or other energy to the working medium of water or other fluid is heated to a certain device parameters. The main areas of application for power plant boilers, ships, locomotives and mining enterprises. So what type of boiler it?

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.
