Presently, Environmental protection has attracted worldwide attention. all the country start to efforts in environmental protection, and the dzl packaged biomass boiler delivery to zimbabwe industry has also affected by this situation, The environmental protection standards in various regions are not uniform, causing problems to customers in use, replacement or purchase. Therefore, we analyzes the above three types boilers, gas boilers, biomass boilers and coal-fired boilers.
It is understood that around prevention and control of air pollution, ecological Environmental Protection Office of Shaanxi Province has formulated the "Boiler Air Pollutants Emission Standards" ( "Standards"), amended the "off key industries in the region of atmospheric pollutant emission limits." In the future, biomass, alcohol fuel dzl packaged biomass boiler delivery to zimbabwe emissions also be included in "Standards".
"Standard" is to integrate and improve the local air emissions standards boilers. "Standard" for the scope of the province, covering coal, gas, oil, various types of fuel such as biomass; using alcohol fuel (e.g., methanol, ethanol, dimethyl ether, etc.), gas-fired boiler with reference to the implementation of emission limits.
After calculation, coal-fired thermal power boilers in Shaanxi Province implementation of the new standards, particulate matter, sulfur dioxide, nitrogen oxide emissions respectively about 0.67 tons 15,200 tons, 1.26 tons, down 27%, 40%, 21%; Burning after transformation of coal boiler, particulate matter, sulfur dioxide, nitrogen oxide emissions can be about 01,400 tons, 1.42 tons 14,100 tons.
With the haze pollution reduction work to promote strong, Shaanxi Province coal-fired generating units and 20 steam tons / hour or more coal-fired boiler to carry out the transformation of ultra-low emissions, will gradually iron and steel, cement and other industries to carry over non-electric low-emission transformation, the original standard has been overtaken by change of environmental situation. Additionally, the Guanzhong area of glass, ceramics, bricks, gold and other industry, there are a certain number of kiln, its environmental requirements leniency.
The revision of the "off key industries in the region air pollutant emission standards", the abolition of the thermal power industry, coal-fired boiler emission limit requirements, these two sectors rose to individual standards province-wide.
It also increases the coke nitrogen oxide emission limits Chemical Industries, gold industry, glass and glass products, ceramic industry emission limits, increasing the concentration of tile industries and atmospheric pollutants conversion approach.
The new standards are expected coke chemical industry NOx emissions will decrease 70%, the sintering process the steel industry, the particulate matter, SO2, NOx emissions decreased by 50%, 72% and 67%, respectively.
Burning biomass fuels provide gas and fuel oil dzl packaged biomass boiler delivery to zimbabwe users a great opportunity to significantly reduce their energy cost and stack emissions. ZG is a leading supplier of solid fuel biomass steam boiler and combustion systems for the industrial market. ZG biomass steam boiler systems provide environmental and energy recovery solutions through the use of superior combustion and heat transfer technologies to industrial, government and hospital customers.
Using Biomass fuel for Process horizontal Steam Boilers Technical Report shows if the moisture content is too low for a given boiler design, combustion temperatures will increase and potentially cause problems with both flue emissions and ash-melting behaviour. Wood ash typically melts only above 1300 C, but other herbaceous fuels have ash-melting temperatures of ~ 1100 C. At excessive combustion temperatures, ash particles will condense on boiler tubes, heat exchangers and other boiler components and lead to corrosion or other irreparable damage to boiler parts.
