Tongchuan City, Shaanxi Province is located in Fenwei plain, it is China's major coal producing area, the unique geographical location determines the Tongchuan coal energy as one of the main economic development. Tongchuan coal to bring rapid economic development, but a large proportion of heavy industry, atmospheric pollution and other issues are very serious. "Winning Blue Sky Battle three-year action plan" published this year, Fenwei plain was a key governance areas. Coal City is not achieved coal, coal is not coal, promote clean heating, Tongchuan City is a serious problem.
Tongchuan party secretary said: "This year Tongchuan 4905 ex situ poverty alleviation relocation of the masses of resettlement housing has been fully completed and turnkey, the actual stay 3763, is a large-scale relocation of mass arrival of new homes in the first year."
After a preliminary investigation, Tongchuan City to improve people's livelihood and environmental protection together, launched a "warm life, warm hearts and minds" of warm winter action. Based on the concept of local conditions, it has been completed in 40 of the city's centralized settlements, reduce operating costs, clear charges. Mastery of natural gas household heating settlements, natural gas boiler wall encouraging people to self-heating; central village of rural resettlement and scattered resettlement households, encourage and guide them to use electric heating and cleaning of heating equipment. All use of clean heating devices are available to the masses 1000 yuan subsidy.
Clean heating, an impact on the masses warm winter, a relationship with Blue Sky Battle Action Plan. It is understood that the city of Tongchuan coal-fired boiler to achieve a global "clear" in 2017. 2018, Tongchuan City by town gas central heating and household heating, rural households in accordance with the appropriate air dispersion of the gas, should the electric power, should be hot is hot, use clean coal coal should guide the masses to reduce the amount of bulk coal use, and the use of clean energy and the masses of poor people winter heating subsidies. Currently Tongchuan City, completed a total clean energy alternative to coal for 27,897, of which 25,196 coal to electricity, coal to gas 2701, the city's clean heating rate of 82%, the basic realization of the coal city does not burn coal, coal is not coal.
According to Eco-Environment Department data show that 11 cities Fenwei plain mean concentration of PM2.5 in October this year to 48 micrograms / cubic meter, down 7.7% year on year. The lowest average concentration of PM2.5 is Tongchuan city, is 38 micrograms / cubic meter.
Electric automatic wns fired fuel steam boiler before use Preparation 1, the operator must understand how the present electric steam boiler, location, performance and working methods of the various accessories. 2, check oil combustion, and each nozzle connection, power supply and the burner, the pump, the boiler installation accessory. 3, clearly the main steam valve open, after closing the normal close it. 4, check the electric steam boiler water level, water level confirmation flexible, normal position. 5, the pressure regulator is properly tuned, regulate combustion damper.
Oil-fired boilers include oil-fired water boilers, oil-fired hot water boilers, oil-fired heating boilers, oil-fired bath boilers, oil-fired automatic wns fired fuel steam boilers and so on. Oil-fired boilers are boilers fueled by light oil (such as diesel oil, kerosene), heavy oil, residual oil or crude oil. Oil-fired boiler, gas-fired boiler, electric heating boiler is more economical than electric heating boiler and more convenient to use than gas-fired boiler compared with vertical oil-fired hot-water boiler.
Steam boiler preventive measures introduced Common Failures and precautions automatic wns fired fuel steam boiler and steam reciprocating pump 1. Biomass boiler is a kind of boiler to biomass energy as a boiler fuel called biomass boilers, steam boilers into biomass, biomass hot water boiler, biomass stove, biomass thermal oil heaters, vertical raw biomass boilers, biomass boilers and other horizontal. Fuel gas boiler is not only fuel but also refers to the gas boiler. Previously no such dual-fuel boiler, burner because either fuel or gas, no dual fuel burners. With the rapid development of the world energy equipment, some European countries begin production and sales of fuel gas burner, dual fuel burner and boiler combination of organic birth of a new breed of boiler - fuel gas-fired boiler. Near the steam boiler room should be equipped with adequate and effective fire fighting equipment. 2. Steam boiler room must have staff on duty 24 hours, the guards take turns, and always check the water level in the boiler, in order to ensure that it is above the safety line to prevent an explosion caused by burning dry. If the fire operation in explosive areas must obtain a work permit fire and take adequate fire safety measures in order to carry out fire work. When the fire should send someone on duty at all times observe the fire situation. 3. A storage vessel containing the non-flammable gas in the boiler room. 4. The staff of steam boiler room must be certified before the arrival of the boiler and proficient technique, it has a certain capacity to detect and recognize security risks. 5. If the boiler safety on a regular basis in accordance with the boiler maintenance procedures, should be carefully examine each of insecurity in the inspection process. 6. Distribution Line steam boiler room disposed defective safety device using a metal tube or pipe nonflammable hard plastic protection switch box should be installed outside the boiler room, respectively, to achieve power, should be prohibited. 1. What is the reason there is no discharge of steam reciprocating pump is? How, how? A: (1) Failure: 1 suction or discharge pipe blockage. (2) out of the stuck valve. There is an air cylinder. (4) a suction tube connected lax. (5) column (live) seriously damaged piston ring. (2) Method excluded: (1) exclusion of pipe blockage. (2) Remove the inlet, the outlet valve on the plug. (3) filled with water, the air is discharged. (4) fastening the pipe. (5) Replace Column (live) piston ring.
