rich husk steam boiler

Recently, Nanchang, Jiangxi Province to fully implement the national environmental protection work conference and the province's environmental protection work conference, combined with the actual situation of the city, issued a "blue sky Nanchang win the Battle of three-year action plan (2018-2020 years)" (referred to as " plan"). "Plan" put forward a management plan for major air pollution problems.

As the relevant departments to actively promote the utilization of clean energy. The city gradually reduce the proportion of coal consumption, by 2020, coal accounted for the proportion of energy consumption dropped to below 65%; principles and has gradually increased the proportion of natural gas energy consumption, adhere to "the electric power should", "should air the gas" to promote natural gas work to build the pipeline, steadily "coal to gas" project.

2018, the main city of Nanchang to the new area, the main city area and open small blue through the open area to expand the range of city ban on burning areas. By the end of 2020, Nanchang County, Jinxian, Anyi required scoping combustion zone ban within the jurisdiction of, and informed consent of the uniform implementation of the municipal government.

"Plan" put forward in 2018, the main city of the new areas into the combustion zone ban, the main city through the open area and a small blue through the open area phasing out the 10 steam tons / hour and coal-fired boilers; 35 tons of steam launch built-up area / out of hours and coal-fired boilers. As of 2020, the city built basically out of the region 10 steam tons / hour and coal-fired boilers, coal-fired boilers within 10-35 tons of steam / hour range is substantially complete alternative clean energy sources, and no longer approve new 10-35 steam tons / hour of coal-fired boilers.

Note that, these condensing boiler cleaning errors occur frequently in many condensing boilers manufacture, transport and installation in a variety of situations will occur, so that the pipe wall boilers accumulate a large amount of dirt or other impurities in the oxide, resulting in the initial boiler run directly heating surface corrosion damage. To this end, boiler manufacturing companies will configure a set of operating instructions for each condensing boilers, including cleaning this one. Then the process consumers condensing boiler cleaning in which errors can strayed, how to avoid it? A chemical cleaning process does not detect the chemical analysis is a very rigorous chemical cleaning process. But if chemical cleaning is not complete, some dirt is not completely clean; and if the cleaning time is too long, there will be over-wash phenomenon; good cleaning effect, a secondary cleaning will waste of raw materials, and waste time. Which will increase the erosion had washed condensing boiler, condensing boilers metal pressure caused by a reduced ability of the normal operation of condensing boilers after impact. Improvements are: chemical analysis must be prepared to detect chemical cleaning processes, test once every tens of minutes acidity, total iron ion concentration, PH value. When two close data laboratory analysis, chemical cleaning end point is reached, and be discharged after reaching the neutral acid. Second, chemical cleaning is not performed after completion of the passivation process is the process of passivating the clean surface of the condensing boiler deactivators re reaction. Since the control point passivated more stringent requirements, if not properly controlled, the passivation will fail, and if the pickling is completed, and only a simple cleaning is finished, which makes the surface to be cleaned boiler condensate prone to two secondary rust, scale condensing boiler capacity decreases, prone to rust improvements: condensing boiler after pickling, passivation must be rinsed, since the passivation more stringent requirements, thus rinsing process must be strictly controlled total iron ions concentration. After rinsing is complete, iron ions tested meet the requirements, the PH value immediately adjusted to strongly basic, and the passivating agent is added, warmed passivation. It can be learned from the above, chemical cleaning condensing boiler there are more abnormal phenomena, and that the life of the condensing boiler, safe operation, energy production had a negative impact, therefore, in order to eliminate these abnormal phenomena, sustainable development and safe use of condensing boilers environment has a very big role.

What industrial boiler rated output yes? What industrial boiler rated output yes? Boiler rated output power refers to the boiler in the established parameters (pressure and temperature) and the premise of ensuring maximum efficiency at a certain time continuous output. For rich husk steam boiler, collectively referred to as the nominal energy of vaporization force, tonnes / hr; for hot water boiler, collectively referred to as rated thermal energy generation. The relationship between the amount of evaporation and heat production: Q = D (iq-igs) 1000 kJ / h where: D ---- evaporation boiler, t / hr ---- IQ steam enthalpy, kJ / kg igs ---- boiler feed water enthalpy, kJ / kg for hot water boiler: QG (IRS-IRS) 1000 kJ / h medium: g- hot water boiler circulating water, tons / hour boiler water irs --- enthalpy, kJ / kg irs --- boiler feed water enthalpy, kJ / kg Note: 1kcal (Kcal) = 4.1868kj (kj)

Electric boiler maintenance measures

In addition to the purchase of electric boilers need strict control of its quality and after-sales is good or bad, when in use should pay attention to some practices, so as to more effectively prevent harm to persons and property.
