Boiler installation of "blast doors," What is the role now on the market most of the china wns fired boilers 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.
Fangkuai Boiler has more than 200 after-sales service outlets across the country. Each after-sales service outlet is equipped with a professional china wns fired boiler technical engineer, providing 24-hour emergency repair services, and has sufficient spare parts and wearing parts all year round, convenient. Customers change in time.
Which Xining industrial china wns fired boilers looking for: Xining industrial boiler find Which? There are a lot of companies need to produce industrial boilers in Xining area, industrial boilers had previously been dominated by coal, but now the purchase of multi-boiler is gas-based. This is also in line with the requirements of the current environmental policy. For the procurement of industrial boiler business, then Xining region, for businesses can be compared within the boiler manufacturers nationwide. The company Xining After initial screening decision Xianxiang fast boiler manufacturers for consultation. In this regard, fast boiler manufacturers for the accounting data for the current production status of the enterprise Xining, concluded that the plant with 1 table 6 tons of industrial gas steam boiler on it. Initially, the company for the transport of Xining boiler still have concerns, however, listened to a detailed introduction side boiler fast personnel of the relevant technology. Completely dispel concerns. At present, the price of the model of industrial steam boiler at around 720,000. Recently, the Xining to fast Boiler companies will conduct field investigation, will talk about specific issues related to time after purchase. Domestic large industrial boiler plant which
This standard at age requirement china wns fired boiler flue soot, sulfur dioxide and nitrogen oxides emission concentration maximum permissible emission limits, and the blackness. This standard applies to coal-fired capacity and intended use of the fuel and emissions of air pollutants manage outside gas boiler boiler, and construction project environment (65t / h) In addition to power generation boilers and pulverized coal is greater than a single output 45.5MW impact assessment, design, final acceptance and after the completion of the sewage management.Free Chat
