5. The installation and acceptance must be worked out according to the requirements of aac plant industrial boiler supplier rules

6. In order to operate quickly, the preparation should be done well after all parts of boiler transporting to the job site.

7. The person is put in charge of the installation of boiler ; fireman is enter into the installation and plumber, bench worker, lifting worker, cold worker, certified welders and helpers should be offered.

Three kinds of cleaning methods, whether industrial aac plant industrial boiler supplier or steam boiler hot water boiler, the water treatment effect due to the different amounts of different kinds of impurities contained in the long-term use will form a dense hard scale. Dissolved oxygen in water and etching the corrosion products will contain a certain amount of scale on the metal occurs. Once the formation of scale in the boiler, the boiler can lead to poor circulation, affecting normal use, may also lead to serious accidents, so be sure to regularly carry out cleaning and maintenance of the boiler. Currently there are ways to remove scale mechanical descaling and chemical cleaning, chemical cleaning can be divided into caustic cleaning and acid cleaning. These three methods have advantages and disadvantages, the user may select a targeted according to their actual situation: 1, mainly mechanical descaling backwash tube, blade, blade like tool, sometimes with water washing for mechanical removal. This method is relatively simple, low cost, labor intensive, poor cleaning, easy to damage the metal surface, cleaning is only applicable to a small area, and a simple structure to facilitate mechanical shovel tool sized steam boiler scale. 2, caustic washed with boiling out for descaling trisodium phosphate, caustic soda, soda ash and other basic drugs, its main function is to loosen the scale and facilitate its fall, caustic cleaning and mechanical cleaning is often performed with. Caustic dosage is: trisodium phosphate 3 ~ 5kg / t; Soda 1--2kg / t sodium 2 ~ 4kg / t. Boiling out pressure is the normal operating pressure steam boiler hot water boiler 2/3 time is generally 24 to 40 hours. Cook stoves, boilers need to always maintain the highest level. After the cook stove, should be allowed to cool naturally, the temperature dropped to 50. About C then drain and open the mechanical descaling boilers timely, so as not to re-harden soft scale. This method is simple, less side effects, but long cleaning time, multi-drug consumption, cleaning is not complete. 3, conventional descaling pickling hydrochloric acid was added inhibitor, sometimes adding a fluoride, a surfactant additive, pickled. More thorough pickling for descaling carbonate scale and rust scale poor effect on sulfate and silicate scale, must comply with the alkali cooking transformation descaling. Not only because the acid can react chemically with the scale, but also corrode metal, boilers acid is a highly technical work, must be borne by the provincial labor department accredited professional cleaning unit. Note that, if there is a steam boiler and hot water boiler operating in parallel, no matter what method is used, before carrying out cleaning must be reliably isolated with all gas, water pipes are connected, to do so in order to improve safety coefficient.

Cool water at the bottom of the steam drum returns to the feedwater drum via large-bore ‘downcomer tubes’, where it pre-heats the feedwater supply. (In large utility aac plant industrial boiler suppliers, the feedwater is supplied to the steam drum and the downcomers supply water to the bottom of the waterwalls). To increase economy of the boiler, exhaust gases are also used to pre-heat the air blown into the furnace and warm the feedwater supply. Such water tube boilers in thermal power stations are also called steam generating units.

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.
