Boiler installation of "blast doors," What is the role now on the market most of the industrial 8t boiler seller turkeys to gas, oil, biomass, electricity as the main fuel, coal-fired boilers because of its harmful pollution levels gradually been changed or replaced. In general, no boiler explosion during normal operation, but if it is due to the improper operation of the ignition or operation, it may cause the furnace or tail or secondary combustion flue explosion, resulting in serious danger of impact. In this case the role of "explosion vent" is manifested when the furnace or flue trace knocking occurs, the pressure within the furnace is gradually increased, when a certain value is higher than the pressure relief device can turn on itself through the explosion vent to avoid the risk expansion to ensure the overall safety of boiler and furnace wall, more importantly, it is to protect the safety of the boiler operator. Currently there are blasting boiler membrane and two kinds of swing-proof door. Swing-proof doors are mostly placed in the furnace wall of the combustion chamber. Their installation position can be divided into vertical and tilting, by the door frame, the door and the hinge member and the like components. The door frame and multi-cast iron round or square, the width of their mutual contact surface generally is 3 ~ 5mm, and to ensure seamless tight. The door is coated with a heat-resistant concrete, which limit the pressure according to a desired thickness value has been calculated or determined experimentally. When the gas in the furnace or flue explosion, the door is automatically turned about the shaft relief, and then shuts itself down. Sealing pressure of the vent door from the inclination angle (usually not more than 30 °) or the downward pressure created by the weight of a weight is obtained. Most membrane blasting explosion vent means on the flue, and a clamping device consisting of explosive membrane. Bursting disc is typically made of a thin metal plate of asbestos, aluminum and stainless steel. When an explosion occurs in the furnace or flue gas generated shock wave pressure to bursting membrane damage, play the role of relief, once the explosion vent membrane after blasting effect, it will not reset itself, the clamping device must be open blasting repositioned membrane. Note 1, the position of general device explosion-proof door on the wall or on top of a steam boiler furnace furnace exit side of the furnace flue fuel gas. 2, explosion-proof doors should be installed in place without the threat of operator safety, and a pressure relief guide tube, it shall not be stored near inflammable and explosive materials, highly preferably not less than 2 meters. 3, activity blast doors require regular manual test to rust dead.

Increase productivity industrial 8t boiler seller turkey system must first be optimized for verification, including the entire steam system for a complete analysis, and focus on some of the energy waste places. Via check can often find opportunities to save energy, increase productivity, and environmental protection have a positive contribution of. Check includes a steam generation, distribution, use and condensate recovery. The main steam waste requiring special attention place: exhaust gas boiler: boiler efficiency emissions system the most important indicators, the loss of energy is the most important place. Combustion air: general air enters the combustion furnace of the genus room temperature, require a lot of heating energy, i.e., the most commonly used power saving mode using a high temperature exhaust gas to preheat the combustion air of boiler, boiler efficiency can be significantly improved. The fuel / air ratio: Proper oil / gas mixture can only complete combustion, if the lack of air, combustion is incomplete, not only smoky pollution, environmental protests caused nearby residents, and easy carbonized grease gun and boiler heating tubes affect performance. If excess air is formed wasted energy, reducing boiler efficiency. Via the oxygen content of the tail gas can appropriately adjust the oil / gas ratio. Oil-fired boiler exhaust gas which content 3%, i.e., the excess air of about 15%, as the standard combustion control.

Since 2019, Taiyuan continue to adhere to the principle of priority to improve air quality, in order to significantly reduce heavy pollution weather as the main direction, ongoing action to combat air pollution, management depth to promote coal-fired industrial 8t boiler seller turkey to achieve 35 tons of steam coal-fired boilers "clear zero".

In accordance with the gas will change, given the need for, after the first stand broken, do not break the principle of non-stand, Taiyuan will continue to carry out the transformation of rural areas, clean heating, heating is expected to complete the transformation of 30,000 before the end of October, the city's rural areas clean heating coverage rate reached 70%.

To reduce coal pollution, coal-fired boiler will also promote the in-depth treatment. October 1, seven more than 65 tons of steam coal-fired boilers and ultra-low emissions completed the transformation. Seven out of 35 tons of steam coal-fired boilers to achieve 35 tons of steam coal-fired boilers all clear.

In the region of the pollution control aspect, the binding improved air quality requirements, the complete electricity instead of coal, coal gas for generation of clean alternative energy area, included in "ban on coal zone", the implementation of joint sheet control. Meanwhile, to further increase the intensity of investigation ban within the "ban on coal zone" small coal-fired facilities, enhance the level of protection clean heating, ensure clean heating effect, and resolutely put an end to bulk coal burning complex, consolidate the "ban on coal zone" construction achievements.

In terms of market control, prohibit the use of more than 1% sulfur, ash than 16% of the civilian bulk coal. Before the end of the civil bulk coal sampling of coal sales business monthly coverage rate of 10%, annual sampling coverage of 100%. Investigated sales of low quality coal units and individuals in accordance with law, concentrate on cleaning up, straighten, banning non-compliance bulk coal supply channels, to crack down on the use of low-quality coal sales behavior, non-coal washery slime, the coal into the civilian market.
