6 Tons Straw Fired Steam Boiler


6 Tons Straw Fired Steam Boiler

3, a low nitrogen gas boiler using more advanced technology, higher thermal efficiency

Gas low nitrogen boiler fast boiler through the use of flue gas condensation heat recovery technology, the high temperature flue gas in the latent heat and the sensible heat portion utilized, the thermal efficiency can be improved by about 20%, more than 103%, significant savings in the late running costs, also reducing operating costs.

Expected by the end of this year, Jiangsu Province, the province will complete the ultra-low emissions below 100,000 kilowatts coal-fired units. It's Jiangsu Province, following more than 100,000 kilowatts ultra-low emission coal-fired units in 2017 renovation, energy-saving and environmentally friendly coal a "first in the country."

According to statistics, Jiangsu Province in energy consumption, accounting for over 60% of coal, which accounts for coal and coal consumption sticking. Industrial emissions of air pollution is the bulk, ultra-low emission power plants, clean coal is to enhance efficiency, promote air pollution control "top priority."

According to the deputy director of Jiangsu Provincial Development and Reform Commission Energy Bureau, Jiangsu Province coal units in the national energy conservation program first started, the fastest progress. In the coal transformation "mentioned standard extended surface" advancing, Jiangsu Province by the national requirements of more than 300,000 kilowatts stand-alone, single expanded to more than 100,000 kilowatts, 100,000 kilowatts this year covering the following units. In order to promote energy saving coal-fired power plant, Jiangsu Province, also the first start price subsidies, together with local award and subsidy, enterprise since the vote, five years invested a total of 23.4 billion yuan.

Price subsidies coupled with strict control of environmental protection, promote the province of large-scale coal-fired power plants, clean production. By the end of last year, Jiangsu Province, a total of 225 sets of 73.6 million kilowatts coal units to complete the environmental transformation. Combined with the transformation of coal to the end of last year, out of sync, Jiangsu Province, small thermal power units 2.95 million kilowatts.

Coal transformation of wide coverage, high standards, emissions dropped significantly. Emissions of coal dust, sulfur dioxide and nitrogen oxides three major pollutants, Jiangsu line monitoring mean values ​​of 2.3 mg / cubic meter, 18.5 mg / cubic meter and 35.5 mg / cubic meter, effective domestic optimal. Transformation, Jiangsu Province, to proceed with flue gas heat recovery, central heating, shutting down small thermal power, 25.7 million tons of standard coal last year to save.

Significantly reduce the amount of coal emissions at the same time, the province "Blue Sky index" every year. According to the Provincial Department of environment statistics, since 2013, the province PM2.5年均浓度连续 six years continued to decline, good days than from 60.3% in 2013, rising to 68% last year.

How to determine dry 6 tons straw fired steam boiler plant accident occurs when the water level has been less than the minimum level of delineation, but the water meter is still able to see the water level, water is mild; when the water meter water level less than visual when, for severe water shortages. The summarized as listed below: (1) Drum Level points less than the height of the water level designated normal; (2) ultra-low level alarm, automatic alarm sounds, alarm lights; (3) superheating steam temperature rise; ( 4) providing the amount of water is not normal, the flow rate is less than the water vapor; (5) the flue gas discharge temperature.

Boiler flue gas temperature high is what causes, what harm? Economic operation of the boiler is one of the urgent need to get important issue, because it involves not only the economic efficiency of enterprises, but also in the growing shortage of energy development environment, to save energy, to achieve sustainable development coordination more important. Exhaust gas temperature is one measure of the boiler is in the state of the economy. The formula for calculating the exhaust gas temperature increasing every 10 ~ 15 ℃, thermal efficiency would be reduced by about 1%, meaning that heat losses increased by 1%.
