Furthermore, when the user selects a steam boiler heating systems, which also need to see what kind of design. Want to make the product better performance, you need to look at their work, what kind of design, which is what kind of product performance in the design of, such as how its design on the back smoke circulation, hearth stoves and how design and so on, these will cause great impact on the performance of the boiler to be, if there is no reasonable design, or is it difficult to have a better thermal efficiency in use, or there is also a certain degree of energy consumption in the use of waste.
When the hot water boiler heating systems scale occurs, we first need to be analyzed scale category, and then determine the specific treatment. Boiler feed water before flowing into the boiler, to conduct water analysis and water softening process, until the water quality meet the national standard to enter the convection tube bundles. When the hot water boiler scale processing, general first pickling, water quality control and then take other cleaning measures. With cleaning measures to detect and replace the structure is seriously affecting the safe use of convection tube bundle. If scaling is particularly severe, only the replacement of the way, if a two pipes scaling serious, stuffy way pipe can be used. However, if a large area of the bundle are serious scale, the use of chemical cleaning more effective. Prior to chemical cleaning, mechanical cleaning may be employed before the loosening dirt, this cleaning effect will be better. For the scale silicates, more pickling effect. But the party fast hot water boiler experts also concluded a more important note: general dirt simple suggestion pickling, so lower costs. Mechanical descaling is generally less than 1 mm scale clean-up, if the amount of scale thickness to be selected in the above pickling.
1, gross domestic product grew 6.6 percent, the total exceeded 90 trillion yuan. Economic growth to match the electricity, freight and other physical volume index. Unit of GDP energy consumption fell 3.1%. Pollution has been treated, fine particulate matter (of PM2.5) concentrations continued to decline.
3, the supply-side structural reforms deepen, the vitality of the real economy continue to release. Increase the "broken force, down" efforts. Promote the steel and coal industry to market-oriented production.
2, continue to adhere to the supply-side structural reforms as the main line ...... take more reform measures, the use of more market-oriented, rule of law means to consolidate the "three to make up a down a" results, and enhance the vitality of micro-main, upgrade the industrial chain level, smooth circulation of the national economy, promote quality economic development.
1, this sulfur dioxide, nitrogen oxide emissions to be decreased by 3%, the concentration of fine particles in key areas (of PM2.5) continued to decline. Ongoing in Beijing, Tianjin and the surrounding Yangtze River Delta, tackling air pollution control Fenwei plain, the strengthening of industrial, coal-fired, three motor vehicle pollution control. Good clean northern heating work to ensure that people warm winter. Strengthen water and soil pollution prevention and control, this chemical oxygen demand, ammonia emissions to fall by 2%.
Pollution prevention and control as a corporate body, must fulfill environmental liability. Environmental governance reform and innovation, both for business according to the law supervision, but also to the reasonable demands, helping to strengthen the guidance and the need for compliance rectification given a reasonable transition period to avoid measures to deal with simple and crude, shut up. Companies have internal motivation and external pressure, pollution prevention and control will be able to make greater progress.
Growth of green industry. Speed up thermal power, iron and steel industry, the transformation of ultra-low emissions, the implementation of the transformation of heavy polluting industries discharge standards. Promote the use of clean coal, expedite the settlement of wind, light, water and electricity consumptive problem.
2, speed up the reform of State-owned state-owned enterprises. Strengthen and improve state-owned assets supervision and promote state-owned capital investment, the company operating the pilot reform, the promotion of state-owned assets. Actively and steadily push forward the reform of mixed ownership. Improve the corporate governance structure, improve market management mechanism, the establishment of professional managers and other systems. Disposal "zombie companies" according to the law. Deepen the reform of electricity, oil and gas, railway, natural monopoly industries to implement separate transport network, the comprehensive competitive business market according to the different characteristics of the industry. State-owned enterprises through reform and innovation, physical fitness, and constantly enhance the vitality and core competitiveness.
If you know the rated working pressure of the hot water boiler heating systems, how to determine the setting pressure range of the safety valve? If a hot water boiler knows its rated working pressure, then it is possible to determine the setting pressure range of the safety valve, which is 1.1 times the working pressure on the lower limit of the pressure value, but not less than the working pressure plus 0.07MPa. In the upper limit of the pressure range, it is 1.2 times the working pressure, but not less than the working pressure plus 0.1 MPA.
