condensing gas boiler for central heating
This standard at age requirement condensing boiler for central heating flue soot, sulfur dioxide and nitrogen oxides emission concentration maximum permissible emission limits, and the blackness. This standard applies to coal-fired capacity and intended use of the fuel and emissions of air pollutants manage outside gas boiler boiler, and construction project environment (65t / h) In addition to power generation boilers and pulverized coal is greater than a single output 45.5MW impact assessment, design, final acceptance and after the completion of the sewage management.
Yangzhou City in Jiangsu Province, the municipal government issued a notice of 2019 annual remediation tasks condensing boiler for central heating, with the text published a list of boiler regulation, as follows.
3, the nitrogen gas boiler oxide (NOx) emission limit is not higher than 50 mg / m transformation, in accordance with other indicators of "boiler air emission standards" in the gas-fired boiler particularly performed emission limits.
(1) prohibits blended with other fuels such as coal, bags and other supporting efficient dust removal facilities, and effectively discharge standards. Emission standards in accordance with "boiler air emission standards" in coal-fired boilers particularly performed emission limits.
Full implementation of the above steam 2,65 t / h coal-fired boiler transformation ultra-low emission, soot, sulfur dioxide, nitrogen oxides, respectively, 10 mg / m, 35 mg / m, 50 mg / cubic meter.
3, disable all kinds of close small coal-fired facilities (tea boiler and furnace operating coal-fired stove, rural production, aquaculture and other coal-fired facilities), switching to natural gas, electricity, solar and other clean energy. In remote rural areas, could be replaced by forming biomass as a fuel, but must use a professional boiler, supporting efficient dust removal facilities, to ensure that pollutant discharge standards, emissions standards refer to "boiler air pollutant emission standards" in particular coal-fired boiler emission limits carried out.
4, a low nitrogen gas boiler and treatment for the transformation, the installation of low NOx combustion by the low NOx combustion mode, etc., to ensure that the nitrogen oxide emission limit is not higher than 50 mg / m. Other indicators according to "boiler air emission standards" in the gas-fired boiler particularly performed emission limits.
5, forming a comprehensive remediation biomass fuel boilers, biomass fired boiler clean-up does not meet the special requirements of the boiler, not supporting a biomass fired boiler emissions and efficient dust removal facilities of non-compliance. To meet the special requirements of the boiler and supporting efficient dust removal facilities, the establishment of accounting and retain more than one year, emission standards refer to "boiler air pollutant emission standards" emission limits in particular the implementation of coal-fired boilers. More than 10 tons of steam installation of gas-line monitoring instruments, and networking with the environmental protection department. Located in the city built-up area forming ultra-low emission biomass boilers implement reform.
6, bulk coal sales within the city limits are all clear according to the law, the use of bulk coal user implementation of the "coal to electricity" for street vendors and other "coal to gas" campaign, a pin number management. At the same time, prohibiting the establishment of long-term supervision mechanism bulk coal, non-bulk coal inflows.
In Nigeria the economic cost of producing this magnitude of electricity by methane gas is estimated at about $2,000/hr.On the other hand it cost virtually nothing or little amount to procure EFB which is seen as a waste by small scale oil Plantation Companies, the only cost incurred probably comes from transportation of the material, thus making the use of EFB very economical as an alternative fuel for firing a CFB condensing boiler for central heating plant.
In the two oil crises of the 1970s, natural gas was used as a fuel for condensing boiler for central heatings.
By the early 1990s, fuel-fired industrial boilers with a certain degree of technological development had a high market share in the boiler market.
