Two of the country this year, the NLD Central Democratic National Construction Association Central and made a number of proposals, to speed up the clean and efficient use of coal mine environmental governance has become a hot topic.
NLD central in the proposal pointed out that China's energy structure adjustment should take Duocuobingju way, multi-pronged approach in phasing suppress excessive coal consumption, promote clean and efficient use of coal, etc., it is necessary to focus on environmental protection, but also to resolve the coal system pressure generated by the financial industry, but also pay attention to the industry employment situation of people's livelihood and social stability.
National Bureau of Statistics recently revealed that total energy consumption in 2018, 4.64 billion tons of standard coal, up 3.3 percent over the previous year, of which coal consumption increased by 1.0%. According to statistics, China's coal demand had reached 4.24 billion tons high point in 2013. From 2014 to 2016, coal consumption declined for three consecutive years, from 2017 to 2018 and began to grow, demand for electricity is the most important factor in the growth of coal consumption in our country return to growth.
NLD central in the proposal put forward, to change the traditional extensive coal utilization, promote clean and efficient use is an inevitable choice to realize energy structure adjustment "soft landing". As most of the early years of huge capital investment in the coal industry to achieve through bank credit, the current coal production capacity is still excess capacity, low coal prices, in this case, it should gradually promote the adjustment of energy structure through technology, etc., should not too quickly, leading to financial system pressure increases, the pressure to raise employment and livelihood.
Proposals suggest that the development of coal-based regional energy center, to achieve energy efficiency an "electricity, gas, cold, heat, water" comprehensive energy plan overall, a substantial increase in thermoelectric projects. Forced to upgrade enterprise technology through carbon taxes and sewage charges, increase the proportion of clean energy use. Regional Center for Alternative Energy Development dispersed small boilers. Accelerate the development of clean coal conversion industry, the direct liquefaction of coal, industrialization indirect coal liquefaction, coal gas, coal, ethylene glycol and other technologies to increase support development efforts.
How to diagnose steam which is best boiler for central heating water shortage accident occurred when the minimum water level has been below the specified height, but still be able to see the water level gauge height, is slightly dry; when the water level is less than the visual height of water, for serious water shortages. A summary of the following phenomena: (1) partial conventional water drum height lower than a predetermined height of the water; and (2) Ultra-low level alarms, audible alarms, warning lights light initiated; (3) water vapor superheated steam temperature is increased; (4) no conventional water supply, less steam flow; (5) increase the temperature of exhaust gas water vapor.
What optimization measures industrial which is best boiler for central heating water boiler plant optimization measures water quality of industrial plant optimization measures which industrial plant boiler water which has 1, an industrial boiler water treatment plant (1) Sample preparation by lime softening process and the soda lime softening implementation, simple treatment of raw water impurities, pH, ions or the like by the above chemicals. First preprocessing the raw water before precipitation, filtration and condensation, thereby reducing impurities in raw water, reducing the amount of scale in industrial boilers; secondly, to process the raw material bicarbonate water by milk of lime, reducing the external water industrial boiler hardness; again, to use the soda lime softening treatment, to adjust the pH of industrial boiler water; Finally, the use of softened plaster, suitable to reduce the concentration of bicarbonate in water by chemical reaction with the sodium salt of gypsum, reducing boiler the C02 gas. Implement (2) in the process of softening primarily by exchange of sodium ions, the original metal cations of the water absorbed by a sodium ion exchanger to reduce the generation of scale in industrial boilers, which has a very positive safeguard industrial boilers for normal use. Process uses a sodium ion exchanger will increase the concentration of chloride ions is appropriate, therefore during processing to properly control the amount of sodium ion exchange agent, chloride ions to prevent sodium ion exchanger caused by excessive use of excessive. Process (3) may be suitably oxygen treated to enhance the boiler temperature, the thermodynamic oxygen, thereby reducing the corrosion rate of the boiler. The method of using the heating process to control water temperature above 105 ^ 0, in order to enhance the effect of oxygen may also be provided deaerator water spray disk. 2, the process of industrial boiler water treatment plant in the boiler water may be appropriately alkali treatment, phosphate treatment and adding sodium humate treatment: can be made to improve overall water quality in the boiler by the above method, adjustment of industrial the pH of the boiler water, total alkalinity, sodium ion concentration, has a very good effect on the optimization of industrial boiler water quality. Alkali treatment process may be suitably added to the people in the soda boiler, to form calcium carbonate and magnesium hydroxide by reaction of substituted acid salt sediment, reduce the concentration of magnesium ion concentration of carbonate ions in the water and calcium ions and metal. Plus phosphate treatment process may be employed in the reaction with magnesium metal phosphate ions and calcium metal ions, alkali treatment and the nature of the same, after removal of the sewage generated crystals. During the addition of the sodium humate treated mainly by the hardness of the softened water sodium humate, magnesium and calcium ions removed, soften water. 3, industrial sewage treatment plant boiler boiler blowdown process as a key industrial boiler water treatment, have a very positive significance to enhance the safety performance of industrial boilers. Industrial boilers during use due to evaporation of water and adding other agents, the concentration of the boiler water will gradually rise and a certain impurities in the boiler, precipitation and the like. Therefore, during the processing of industrial boilers regularly to turn on the water, will be discharged from the high concentration of water in the pot boiler. In addition, you also need regular cleaning and maintenance of industrial boilers, the use of chemical materials on the scale inside the boiler completely clear, so as to ensure clean the boiler heating surface, extend the life of industrial boilers.
In natural gas fuel for example, the high heat of about 9500kcal / m³, low heat generation of about 8600kcal / m³, a difference of about 900kcal / m³, 11% of low calorific value, choosing condensing which is best boiler for central heating compared to the conventional type boiler reduce operating costs of gas around 11%. (High and low calorific value science as detailed in another article)
Although rare, some boilers burn coal (usually in the form of coal pellets) or biomass (usually in the form of wood chips). Electric central heating boilers are also available. New gas (and oil) boilers have to be of around 90% efficiency or higher (an A or B energy efficiency rating)Learn More
Best Oil Boiler. Just like gas boilers, oil-fired boilers use oil to heat water and supply central heating through your radiators and hot water through your taps and showers. For an oil boiler to function, youll need to have a constant supply of oil delivered to your property throughout the year and stored in an external tank.Learn More
