How to maintain the 20t boiler cheap armenia shutdown? After boiler shutdown cooling, heating surface must be thoroughly cleaned of fouling and ash grate the upper, the lower portion of the furnace. Then to maintain a certain degree of natural ventilation flue. In general, in order desiccant moisture should be placed in the furnace, flue. The quicklime as a drying agent, within the furnace or flue gas per cubic meter should be placed generally about 3kg. After placing all the ventilation should be tightly closed doors. After the change of lime powder to be replaced. Low-lying position as boiler room, ground during shutdown severe flood tide, often approach should be used and placed a small fire to dry desiccant combination. How to care? If the boiler shutdown a long time, the boiler shutdown after complete removal of soot coated with an anti-corrosion red lead paint in oil or other metal surface furnace. As internal corrosion Maintenance shutdown of the boiler body, under normal circumstances, can be used wet shutdown maintenance is not more than one month, one month electrically operated steam boiler should be taken to dry more maintenance. To note the following problems when a dry maintenance: desiccant boiler not in direct contact with the metal surface, may be mounted in a container such as the iron plate after the desiccant is placed, and a hole for shutting the other hand hole cover.
Natural gas as a clean energy, can be reduced nearly 100% of the sulfur dioxide and dust emissions, 60% of carbon dioxide emissions and 50% of nitrogen oxide emissions, and help to reduce acid rain, global warming alleviate, reduce proportion of the amount of coal energy important energy; corresponding gas 20t boiler cheap armenia has gradually been used and popular.
Our environmental management efforts continue to increase, located in Wuhai City of Inner Mongolia is also actively respond to national policies, by removing, shutting down non-compliance of the measures within the jurisdiction of coal-fired 20t boiler cheap armenias, etc., to improve air quality within the city.
Recently, a reporter to follow the staff Haibo Bay Area environmental monitoring brigade, examined the case of shutting down coal-fired boilers in rural areas. Trinidad town in Wuhai unity Village, coal-fired boiler is the main source of heat in the village residents, schools, hospitals in the town and airport, but because they do not meet environmental requirements, the boiler has been officially shut down at the end of 2018. Haibo Bay Area Environmental Protection Agency environmental monitoring battalion to us to: "Removing the boiler is 20 tons of steam coal-fired boilers, each heating season about to burn more than 3,000 tons of coal in accordance with the municipal government requirements. within the deadline 20 tons of steam boilers to be all removed, replaced with clean energy. since November 2018, this block of sea area has access to a central heating all children. "
So far in 2013, Wuhai City in strict accordance with regulatory requirements grid, earnestly implement the responsibility of inspectors on-site supervision, and has eliminated 20 tons of steam coal-fired boilers for heating and tea bath furnace 791 units, of which 2018 out of 58 units. Meanwhile, municipal and district environmental protection departments at all levels to increase on-site law enforcement and ensure that the boiler is no longer out of the resurgence. Up to now, it has no built-up area of Wuhai City and 35 tons of steam coal-fired boilers to achieve a stable discharge standards.
Method of reducing the exhaust gas temperature of the 20t boiler cheap armenia 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.
