Recently, the Xinjiang region issued on the overall strengthening of environmental protection and resolutely fight pollution prevention tackling embodiment, the program provides: Complete with ultra-low emissions and energy-saving transformation of the conditions before the end of 2020, coal-fired power plants. Gradually shutting down key areas do not have the conditions for the transformation of highly polluting coal-fired power plants.

Implementation of the program focus on the regional party committee, "1 + 3 + 3 + reform and opening up" work arrangements, accelerate the construction of ecological civilization system to ensure that by 2020 the basic layout of the formation of the main functional areas, land space development pattern was further optimized, the total emissions of major pollutants and the amount of energy consumption per unit of GDP dropped significantly, significantly reduced the number of heavy pollution days. Specific indicators: the region of fine particulate matter (of PM2.5) concentrations of the standard level cities not decrease by 15% in 2015, the level of urban air quality days ratio reaches 71.6%; good monitoring of river water quality of the region (or superior to class III) ratio of not less than 97.6% (national quality evaluation section 47 excellent no less than 91.5%, worse than Grade V ratio of not more than 4.28%), focus on monitoring water quality of lakes and reservoirs of not less than 71%; sulfur dioxide , nitrogen oxides, chemical oxygen demand, reduce ammonia emissions into the 2015 3%, 3%, 1.6%, 2.8%; contaminated land safety utilization rate of 98%, contamination of land utilization is not safe less than 90%; the red line accounted for ecological protection area of ​​not less than 25%; forest coverage rate reached 5.6%.

Program has clearly pointed out, we must strictly control the total coal consumption, accelerate the use of clean energy alternatives. Study the development of the region's total coal consumption embodiments and independence - - "Kui" Ukraine - - Chang stone "of the total area of ​​coal consumption Ukraine" reduction plan, the implementation of the target responsibility management, controlling the total coal consumption. Delineation work carried out high-pollution fuel combustion zone ban, ban the sale in the region ban on burning, burning high-polluting fuels. Increasing the use of clean energy, clean energy consumptive broaden the channels, the implementation of policies for renewable energy generation full protection of the acquisition. Promote clean low-carbon energy sources priority access. Encourage waste heat, shallow geothermal and other clean energy sources for heating. Strengthening the CBM (coal gas) utilization, in an orderly bulk coal in key areas of governance, the implementation of biogas projects.

The implementation of comprehensive improvement of coal-fired boilers. The promotion of clean and efficient coal-fired boiler, strict implementation of coal-fired boiler emission standards. The region above the county level cities and built-up area basically eliminated 10 tons of steam per hour coal-fired boilers and furnaces and tea, operating the stove, grain storage and drying equipment, coal-fired facilities, in principle, to a new 35 tons of steam per hour coal-fired boilers, in principle, to the rest of 10 tons of steam per hour, a new coal-fired boilers. Ambient air quality did not meet the city should increase efforts to eliminate further. Key areas basically eliminated 35 tons of steam per hour of coal-fired boilers, 65 tons of steam per hour and above all coal-fired boilers to complete the transformation of energy-saving and ultra-low emissions; low nitrogen gas boiler basically completed the transformation.

In the region the implementation of ultra-low emissions and energy-saving coal-fired power plants, encouraging "Wu - Chang - Stone" to carry off white smoke fired power plant pilot area. Before the end of 2019 to complete the "Wu - Chang - stone" "Kui - ultra-low emissions and energy-saving black" area, and Korla Ili River Valley and surrounding areas with the transformation of the conditions of coal-fired plants, in other areas before the end of 2020 - only carry out.

What is a modern large-scale hole in boiler pipes, industrial boilers and what is the difference between: industrial boilers and power plant boiler structures have their own characteristics. Higher boiler power plant parameters, the structure is more complicated, suspension structure, membrane wall rarely used in industrial boilers, utility boilers, but in a wide range of applications. With the improvement of the working pressure, the vaporization heat boiler to reduce the proportion, increase heat absorption overheating. Utility boilers have been arranged in the furnace wall to meet the requirements of the evaporator heating surface, so that no longer as industrial boilers, evaporation convection bank is often necessary, even more superheater is disposed, and even part of the superheated heating surfaces are arranged in the furnace . Large capacity and high parameter boiler reheater is also arranged.
