New gas-fired boiler construction simultaneously low NOx combustion facilities, low NOx combustion is completed before the end of December 2019, the transformation of existing gas boiler. City and county built-up areas the implementation of ultra-low emission biomass boilers transformation.
3, bulk coal use to carry out special rectification. Using coal for use in all high-quality coal, coal mines by 2020, all built to retain supporting washing facilities, the city's raw coal rate of 90%. In accordance with the principle of progressive advance of Pingba first, and then the mountains, the "coal to electricity," which, according to local conditions in key areas to promote rural villages, "coal to electricity, coal to natural gas" work. A total ban on the circulation and use of low quality coal, bulk coal investigate unlicensed business activities according to the law, high-pollution fuel combustion zone ban is abolished bulk coal sales outlets, to promote electricity instead of coal, substitution of gas for coal, to promote the use of clean coal, advanced civilian stoves . In 2020, within 30 km surrounding county town and township range of the main city of almost no bulk coal use.
4, accelerate clean energy alternatives. The implementation of "gasification of the city, alternative energy, clean alternative" projects, subsidies to change the electric boiler. 2020 non-fossil fuels in primary energy consumption should increase to more than 38%. Research to develop new energy truck traffic right of way, to encourage policies on sustainable management, new and replacement buses, rental, sanitation, postal services, commuter, logistics and other light vehicles with electric vehicles. By 2020, postal services, urban delivery, light sanitation basic vehicle for the electric car, for the van passes light logistics vehicle essentially electric cars, buses central city using all new energy vehicles and reached the country six emission standards for natural gas clean energy vehicles.
It is well known that the petroleum and petrochemical industry is inseparable from the use of large-scale steam boilers for thermal energy conversion or filtration use. The reason why steam-type boilers will be selected for processing use. Because not only high thermal energy but also energy-saving and environmental protection can meet the needs of petroleum and petrochemical industry. Professional steam boiler can not only help the petrochemical industry to process smoothly, but also help enterprises to produce huge economic benefits to improve the production of petroleum processing. Let's follow the editor to see why steam boilers are used in the oil industry:
1, it can save processing costs more effectively because steam boilers can save energy and environmental protection in the process of processing and use to reduce power consumption, so the use of the corresponding in the petroleum and petrochemical industry can reduce the larger cost investment. Moreover, steam boilers use electric energy to process and use, so they can effectively save a lot of energy consumption and help enterprises reduce costs. Reducing the cost can be more beneficial to the petrochemical industry to use a large number of processing to improve economic efficiency.
2, the reason why steam boilers are selected for long-term processing and use in the oil industry with high safety and stability of steam pressure is also because steam boilers are stable in operation and can carry out effective range control. Moreover, the boiler can control itself in the safe operation of steam pressure value, and ensure the safety and stability of the equipment in the process of operation. Therefore, it is especially suitable for petroleum and petrochemical industry with large processing capacity and long duration.
3, boiler energy-saving technology highlights that petroleum needs the conversion of boiler thermal energy in the refining and chemical process to carry out normally, and steam boiler has unique energy-saving technology and can automatically feed water through frequency conversion technology. Moreover, the steam temperature and pressure can be automatically adjusted under stable conditions, so it can be more energy-saving and stable compared with the continuous working process, and it can also save energy and reduce emissions while ensuring the normal supply of petroleum processing at the same time.
Weather gets warmer, electric hot water boiler heating season many are also beginning to use the outage. But even the shutdown of the boiler, we can not ignore the maintenance of electric water boiler, furnace inside and outside to prevent corrosion problems arise. Well, you know how the future electric water boiler shutdown maintain it?
1, the electric water boiler shutdown after cooling, the elimination of the heating surface fouling and ash grate the upper, lower part of the furnace.
2, to maintain a certain degree of natural ventilation flue. In general, in order desiccant moisture should be placed in the furnace, flue. If quicklime as a drying agent, needs to be placed within about 3kg lime per cubic meter flue or furnace, should be closely placed after all the vent door closed. Need to be replaced after lime turn pink. 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. If the boiler shutdown a long time, after the complete removal of soot coated with an anti-corrosion red lead paint in oil or other metal surface furnace.
3, as anti-corrosion maintenance methods inside the furnace shutdown, the shutdown Yaoan the length of time to be. In general, no more than one month shutdown maintenance wet available, more than one month should be taken to maintain dry.
Four advantages pressure hot water 1500kw horizontal electric hot water boiler pressure hot water boiler as a commonly used heating equipment, widely used in various occasions to people's daily lives has brought great convenience, not only saves a lot of resources and created high economic efficiency at the same time on the market has also been warmly welcomed by many users, and has been in demand ever-increasing trend, while customers adhere to the selection pressure hot water boiler is mainly because of this four technological advances of this type of boiler.
