Dry maintenance method should be adopted to stop oil-fired boiler for more than one month, wet maintenance method should be adopted for less than one month after shutdown. During the maintenance period should be micro-fire oven, according to the cycle of water, so that the concentration of alkaline solutions are the same. Every five days also take alkaline solution test, such as alkalinity less than 5-12mmol/1 should be added to the solution.
Condensing steam boiler is a common boiler equipment, because of the advantages of advanced heating technology, it has captured the hearts of many enterprise users. Heat-resistant and wear-resistant condensing steam boiler has gradually become the mainstream boiler approved and chosen by many enterprises because of its own characteristics and outstanding boiler products. Let's not see why the condensing steam boiler is chosen for use:
The main advantage of the 20 ton circulating fluidized bed boiler is its superb fuel flexibility. Most of the over 80 references around the world are multifuel boilers that combust biomasses and fossil fuels in continuously varying proportions. Co-combustion is an environmentally benign method of combining excellent reliability and availability with a great potential to optimize operational costs by allowing several fuel alternatives.
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.
