Boiler installation of "blast doors," What is the role now on the market most of the energy saving condensing 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.
3 ton Fire tube gas fired steam boiler as one of the implementation subitems awarded by the world bank GEF efficient environmental protection boiler project, which is developed by ZG Boiler for the technical cooperation with the German, has reached the advanced world level, and is in the leading level of domestic boiler industry.
3 otn Fired tube gas fired steam boiler for sale in ZG Boiler adopts the international popular three return structure with big volume design of combustion chamber, and it can make the burning more fully. The corrugated furnace structure not only increases the heat transfer area, but also satisfies the free expansion after the furnace is being heated. It has a wide fuels adaptability, not only gas, but also oil, light oil, heavy oil, city gas, biogas and so on all can be its fuels.
Method of reducing the exhaust gas temperature of the energy saving condensing boiler which: standard boiler exhaust gas temperature: between the boiler flue gas temperature of 200-230 deg.] C in accordance with conventional design national standard thermodynamic calculation boiler design requirements. Conventional exhaust gas temperature selected reasons, coal fired boiler combustion process will produce a certain amount of SO2, and SO2 below 170 ℃ will bind and generating flue gas H2O H2SO4 sulfuric acid, H2SO4 sulfuric acid and will form boiler heating surface of tail corrosion, thereby reducing the life of the boiler, conventional coal-fired boiler exhaust gas temperature is higher than 200 ℃. Temperature is high energy loss and more, is not conducive to energy saving. Cooling measures taken to ①, the economizer application: increasing the boiler economizer (economizer) of heat transfer area, larger than the conventional take about 1-2 times the flow cross sectional area economizer structure, effectively reduce smoke flow rate, to strengthen the heat transfer efficiency, reduce exhaust gas temperature; ②, air preheater applications: pipes connected to the air preheater economizer disposed, the apparatus can effectively increase the temperature of the combustion air, improving the ignition of the fuel condition. Very beneficial to the boiler combustion conditions. ③, adjust bidirectionality combustion system, a boiler originally designed for fuel specifications have some flexibility, different media in effect outside the combustion process are different, adjusting the embodiment, with the economizer and the air preheater using, the temperature of the boiler exhaust emission control at a suitable temperature, that make full use of heat energy, but also to ensure the integrity of the structure and function of the relative equipment, environmental protection, energy saving, security and development is the social responsibility of all of us for a rational design of industrial structure boiler, thermal efficiency is relatively high, its emissions would be relatively low temperatures, so we must be careful when choosing a boiler boiler property report form.
Hot water energy saving condensing boiler in the school dormitory and classroom building are generally used for central heating, drinking water and bathing water aspects of teachers and students and so on. Shanxi Linxian County high school is an important educational school personnel training for the community. 2017, the school responded positively to national coal to gas and other environmental policies, but also to provide students with a more favorable living and learning environment, the school decided to phase out conventional coal-fired boilers, clean and environmentally friendly replacement for the gas boiler. After getting to know and choose the boiler industry, major companies, determined cooperation with professional production of clean fuel boiler fast boiler-by-side to provide a fast 4.2MW integrated condensing gas hot water boiler (WNS4.2-1.0 / 115 / 70-YQ).
