electricity water tube boiler for sale
The new patent of waste heat electricity water tube boiler for sale for the waste gas of coke has avoided the defects of the traditional horizontal waste heat boiler with one flue gas channel or multi flue gas channel. Coking Waste Heat Boiler can organically combine the various components of the boiler without the change of their functions, centralize the heating surface, simplify the structure in the coking waste heat boiler and achieve the multi-function composite of the various components. This new patent of waste heat boiler for the waste gas of coke has the functions of high efficiency heat transfer, two-level of soot separation in the boiler. It achieves the advanced level in China because of its compacted structures, novel structure, low cost, small floor area, environment protection and energy conservation.
Battle for winning Blue Sky, effectively improve the region's ambient air quality; Ningxia Hui Autonomous Region developed and published a "region-owned coal-fired thermal power units reconstruction plan for the ultra-low emission" (hereinafter referred to as the "Program"). "Plan" put forward plans before the end of 2020, nine companies owned coal-fired power plant 25 thermal power units for ultra low emissions transformation.
By the end of 2020, all the region's coal-fired thermal power units with self-transformation conditions by upgrading desulfurization, denitrification and dust removal facilities, the concentration of pollutants in atmospheric emissions all meet ultra-low emission requirements; long-discontinued businesses in the pre-production must be restored owned ultra-low emission coal-fired units to complete the transformation; gradually shutting down key areas do not have the conditions for the transformation of high-polluting coal-fired captive power plants; emission concentration of air pollutants new coal-fired gas turbine generator set to achieve set emission limits; the country City and Ningdong Management Committee in conjunction with the region's environmental quality improvement requirements, and actively promote the transformation of ultra-low emissions to arrange more than 65 tons of steam per hour of coal-fired boilers.
After the completion of the transformation project, owned coal-fired power plants should entrust a third party consultant for technical performance, environmental effects, equipment stability, comprehensive assessment, evaluation findings and issue.
In order to encourage enterprises to increase efforts to transform ultra-low emissions of pollutant emission concentrations below the pollutant discharge limits set by the state or place more than 50 percent, halved implement environmental tax policy. At the same time, we encourage financial institutions to give preferential credit support, to support eligible owned coal-fired thermal power enterprises to issue corporate bonds direct financing, to raise funds for ultra-low emissions and energy saving. According to the regional administration of appropriate incentive funding arrangements, to ultra-low emission reduction projects included renovation crew around them, give appropriate incentives based on emission reductions, combined with local conditions to increase financial support.
"Plan" requires all localities and departments should strengthen daily supervision and inspection of law enforcement to prevent corporate fraud, is not scheduled to complete the transformation of the self-ultra-low emission thermal power phase-out, discharge permit authorities to promptly subtract the emissions permit, for non-compliance business severely dealt with according to the law, to the public.
Why electricity water tube boiler for sale flue gas dew point as low as possible? In order to prevent corrosion and fouling of the rear of the boiler heating surface, in the design of the boiler tube wall to make the low-temperature air preheater flue gas temperature above the dew point, and to leave some margin. If the flue gas dew point is high, the exhaust gas temperature of the boiler must be designed to be higher, so that the loss of exhaust gas must increase, reducing the thermal efficiency of the boiler. If the dew point of the flue gas is low, the exhaust gas temperature can be designed to be lower, can improve the thermal efficiency of the boiler.
Reference for matching based on coal-fired electricity water tube boiler for sales for SMEs Many SMEs in matching coal-fired boiler will always encounter do not know how to judge its quality of authenticity Di distress, then, Eastern Machinery As a person in charge Di manufacturer, special summarize three elements for each business owner a reasonable option. 1, first the amount of evaporation, the capacity of the boiler should be close to the maximum amount of steam produced or with heat. Preferably, the amount of steam production is about 80% of the rated boiler evaporation. Because the loss of pipe, boiler scale, soot and so will cause the boiler deviates from the ideal operating conditions such as. The need for additional reminder, evaporation is the evaporation of the boiler plate under pressure, while some foreign boiler that evaporation is zero amount of evaporation reduction, the actual boiler output vary greatly. 2, when the feed water temperature is the same evaporation plate, boiler feed water has a temperature of 20 ℃, 60 ℃, 90 ℃, 100 ℃, 105 ℃ are five. Due to the high and low water temperature, the actual boiler evaporation will have a greater difference. For example: there is a large difference output 20 ℃ boiler output water temperature and water temperature of 100 deg.] C. 20 ℃ boiler output water temperature is 114% of the output water temperature of 100 deg.] C. 3, the pipe resistance rated steam pressure should be greater than the sum of the boiler plate steam supply pipe resistance and operating pressure needed for the production. Do not overlook the steam pipe resistance, due to its higher rated steam pressure saturated steam temperature is higher.
