100mv natural gas fired boiler delivery to indonesia
Hebei Cangzhou issued a "special program on the implementation of standards of governance 100mv fired boiler delivery to indonesia." Emission standards for boiler treatment and corresponding indication made, as shown in details as follows.
First, the standard standard coal-fired boiler
1, before the end of September 2019, within the city of more than 35 tons of steam / hour ultra-low emission coal-fired boilers complete transformation, emissions of major pollutants to achieve ultra-low emission standards (dust ≤10mg / m³, SO2≤35mg / m³, NOx≤50mg / m³).
Before the end of the year 2/2020, the city eliminated 35 tons of steam / hour and coal-fired boiler, stove and stove operating a small coal stove, achieved within the city 35 steam tons / hour and the boiler "No Coal." Reserved 35 steam tons / hour and coal-fired boiler, stove and stove operating a small coal stove implementation of the special emission standards (dust ≤30mg / m3, SO2≤200mg / m3, NOx≤200mg / m3).
Retention of more than 35 tons of steam / h coal-fired boiler to install air pollution automatic monitoring facilities and networking with the environment department, to install a distributed control system (DCS system), real-time monitoring of pollutant emissions.
Second, gas-fired boiler
1, before the end of September 2019, the city completed two-thirds of the total number of units of low-nitrogen transformation gas boiler above. Among them, the central city of all gas-fired boiler and all the city's industrial and commercial gas-fired boilers to complete a full rebuilding mode low nitrogen.
2, the end of June 2020, the conventional gas boiler should be completed by transformation of a low nitrogen combustion, soot, sulfur dioxide and nitrogen oxide respectively 5mg / m³, 10mg / m³, 30mg / m³.
Third, the task
1, increase clean energy alternatives. In areas not covered by central heating pipe network, and vigorously promote geothermal, wind, solar and other clean energy, in an orderly way from coal to gas and coal to electricity, to change the power-based. In 2020, under the conditions of gas supply has been guaranteed, the city eliminated 35 tons of steam / hour and below the coal-fired boilers.
2, increase the coal management and control efforts. Coal infrared video monitoring devices to increase coal quality sampling efforts, to retain the blast furnace coal-fired boilers to be installed, Hebei coal to meet local standards "Industrial and domestic fuel coal" (DB13 / 208102014) non-coal power generation industry quality indicators .
3, strict new boiler access. Ⅲ class urban area and high-pollution fuel combustion zone ban municipal government designated a ban on new coal-fired boiler, a citywide ban on new 35 steam tons / hour and coal-fired boilers, the new 35 steam tons / hour of coal-fired boilers must in line with the municipal government of central heating planning or construction of industrial parks planning, energy efficiency reached AQSIQ "energy-saving technology supervision and management procedures boiler (TSGG0002-2010)" requirements, encourage the use of "energy efficient boiler promotion List" reached the level of energy efficiency standards boiler, pollutant emissions to meet emission standards require extremely low.
Low nitrogen gas 100mv fired boiler delivery to indonesia transformation of environmental significance where the transformation of low nitrogen gas boiler environmental significance where, although natural gas is clean energy, but the combustion process will produce nitrogen oxides, is one of ingredients to form haze. According to the city Thirteen Five energy planning period, from 2014 to 2020, natural gas consumption grew by 14.6 billion cubic meters to 20 billion cubic meters. If you do not take low-nitrogen transformation, the combustion of natural gas will be the main source of nitrogen oxide pollution. After the combustion gas temperature exceeds 1400 ℃, it will generate a lot of nitrogen oxides. Thinking boiler low nitrogen transformation, which is to reduce the combustion temperature to suppress the generation of nitrogen oxides. Chaoyang District Beijing EPB said responsible person, after the transformation, the furnace temperature was controlled at below 1000 ℃, supplemented by staged combustion, flue gas recirculation techniques, such that the concentration of nitrogen oxides is greatly reduced. In recent years, the state vigorously promote clean air plan, Yajian coal. Whether the use of coal-fired central heating boilers, and rural small coal stove for cooking and heating, have changed after another coal to gas in coal, that is, the use of electricity, natural gas and other clean energy alternatives. Thus, in recent years, sulfur dioxide, dust content in the atmosphere continues to decline. But it is worth noting that more and more use of natural gas, also caused a certain amount of nitrogen oxide pollution.
The power plant in Bulgaria consists of 11 100mv fired boiler delivery to indonesias sized 160 and 220 t/h, fired with natural gas and coal. In order to meet the changing emission regulations and to reduce the fuel cost the customer was interested in replacement of 2 existing 220 t/h gas-fired boilers with a new CFB boiler fired with petcoke and Ukrainian semi -anthracite. Gas boilers no 7 and 8 were demolished, this space was used for a new CFB boiler plant .
All say that the difference between coal-fired 100mv fired boiler delivery to indonesias and gas boilers, it is a lot of, but the main reason is the elimination of coal-fired boilers - environmentally friendly. 1, the fuel supply portion, the boiler need only a gas pipe connected to the boiler; have the coal fired boiler field, coal (belt or artificial), coal in the coal transportation, handling, storage and boiler process will produce dust, causing serious pollution to the environment of people's lives. 2, the discharge from the atmosphere, the dust content in the gas is very small, substantially negligible; while the coal ash containing a large, about 10-30% ash content after combustion smoke generation. Dust removal facilities do less, and pollutant emissions will rise; dust removal facilities do more, and the corresponding costs will rise, not a permanent solution.
