4 ton steam boiler manufacturer
Generally, the thermal efficiency of the boiler in general about 85% -91%, while the thermal efficiency of the condensing boiler can be higher than 100%, fast boiler even reach 108% of the height. This extra 10% -20% is derived from condensing technology takes advantage of sensible heat and latent heat part of the boiler operation.
Reference for matching based on coal-fired boilers 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.
First, look at the use of natural gas 4 ton steam boiler manufacturers, the use of this material most prominent advantage is that there is no contamination, because natural gas belongs to clean energy, the combustion will produce oxygen and carbon dioxide, will not pollute the air and can produce a lot of heat, but also has some disadvantages, must have certain conditions, it can be switched on gas, when using a steam boiler, if the combustion of natural gas liquefaction, the cost is relatively low, in general, generate one ton of steam consumes 240 yuan gas.
Zhejiang Yiwu issued the "Yiwu winning Blue Sky Battle 2019--2020 action plan." Plan to improve air quality, enhance people's happiness index target put forward concrete measures of implementation, as follows.
1, vigorously develop clean energy. In-depth implementation of the "creation of a national clean energy demonstration Zhejiang Province Action Plan (2018-2020 years)" "Zhejiang three-year action plan for natural gas development (2018-2020 years)" and "Jinhua" Thirteen Five "Renewable Energy Development planning". According to "gas of the gas should be '' should the electric power" principle, energy companies actively guide clean energy alternative embodiment, in 2020, the proportion of the power in the final energy consumption of clean energy consumption accounting for the higher level, the city gas consumption amounted to 150 million cubic meters.
2, control total coal consumption. Strengthen energy consumption and total energy consumption intensity dual control, strict new coal project access, new (modified, expanded) construction project coal consumption reduction of coal instead. By 2020, the city's total coal consumption by 2015, down from more than 5%. Continue to promote alternative energy coal and oil, replace reached the national requirements. No new 35 t steam / hour or less polluting fuels boilers. Strengthening coal quality control, promote clean coal utilization. Before the end of 2020, clean coal utilization rate of 92%, the proportion of electricity than to accept deliveries in 2017 significantly increased.
3, to carry out comprehensive improvement of coal-fired boilers. Increase efforts to eliminate small coal-fired boilers, the urban built-up area basically eliminated tea furnace, operating a stove, grain storage and drying equipment, coal-fired facilities; basically out of 10 steam tons / hour and 35 steam tons / hour coal-fired boilers. 35 t steam / hour and more polluting fuels boilers completed ultra-low emissions and energy transformation. Low nitrogen gas boiler basically completed the transformation. Strict control of the new urban area of biomass boilers. Biomass boilers should be dedicated boiler, blended prohibit other fuels such as coal, and other supporting efficient dust bag embodiment, non-coal, oil, natural gas-fired boilers and the like directly Burning biomass briquettes.
4, the positive development of central heating. Cogeneration units to increase the technological transformation efforts, speed up the heating pipe network construction, improve the heating capacity and the full release before the end of 2020, phasing out the cogeneration district heating pipe network coverage and high pollution coal-fired boilers in the range. In the area where no cogeneration district heating conditions, a plurality of existing small coal-fired boilers, an alternative construction of large-capacity coal-fired boiler in accordance with the principles of the reduction or the equivalent.
5, deepening the construction of high-pollution fuel combustion zone ban. According to "adjust Yiwu prohibit the use of polluting fuels sales area plan" (Yi Zheng Ban Fa  No. 180) documentation requirements, a comprehensive investigation and eliminate high-polluting fuel facilities within the city, to ensure that no dead ends, no blind spots, Finish high pollution fuel combustion zone ban burning building before July 2019.
6, improve energy efficiency. Vigorously develop, promote energy efficient technologies and products to achieve key energy industries, energy-saving equipment standard full coverage. New energy-intensive projects per unit of product (output) energy consumption should reach the international advanced level. Local conditions to improve building energy efficiency standards, and increase efforts to promote green building, city guide implementation of green building standards for new buildings. Renovation of existing residential buildings to promote energy conservation, encourage rural energy-saving housing.
