And pharmaceutical boiler types can vary depending on fuel source, unit location, emissions, boiler controls, and heating requirements, and coal, oil, gas, biomass energy are the main pharmaceutical boiler fuels. ZG Boiler can guarantee the customers obtain the highest efficiency of the pharmaceutical boiler by repairing or upgrading super heaters, water well panels, power and process piping, drums, and more.
Recently, the Ministry of Environmental Protection by the volatility of the newly revised "Boiler Air Pollutants Emission Standards" released in July this year, the implementation of this standard is known as by far the most stringent air pollution emission standards for boilers, boiler caused by the manufacturing sector.
Compared with the existing standards, new standards not only revised the traditional particulate matter and sulfur dioxide emission limits, for the first time proposed emission control standards for nitrogen oxides and mercury, Forced boiler manufacturers have to upgrade technology, from the source control boiler discharge atmospheric pollutants.
One side is desulphurization and denitrification entered the final stage, while the new emission standards of air pollutants are being introduced amendments to the boiler. Such as pollutant emissions from large wide range of small capacity monomer emission coal-fired boilers and other issues close to the ground long standing will once again be enlarged, comprehensive improvement of coal-fired boilers will undoubtedly become the next focus of urban air pollution control. Analysts believe that the implementation of the new standard direct-driven investment in environmental protection will reach 370 billion yuan to 4500 yuan, while the boiler manufacturing industry is facing exams has also led to the relevant environmental protection equipment market to break out again.
By the end of 2011, our country in the boiler 620,300 units, of which 09,700 units utility boilers, industrial boilers 610 600 units, with a total capacity of about 3,515,900 kilowatts. In 2012, industrial boilers reached 62.4 million units, about 98% of the total number of boilers.
In industrial boilers, coal-fired boiler is more than 80%, the annual consumption of 490 million tons of standard coal, the average efficiency of 65% to 70%, emissions remain high.
In 2012, coal-fired industrial boilers cumulative emissions of dust 4.1 million tons, 5.7 million tons of sulfur dioxide, nitrogen oxides 2.0 million tons respectively, accounting for 32% of total national emissions, 26% and 15%, a major cause of fog and haze one of the reasons.
For this reason, in the 2013 set off a nationwide clean energy alternative coal-fired boiler boiler, more than one place Shandong, Shanxi and other relevant measures have been introduced on clean energy alternative to coal-fired boiler work. "The introduction of the implementation of the most stringent standards, will set off a coal-fired boiler in the second round.
Four existing small and medium sized coal-fired boilers in China. One pollutant emissions from large, wide surface. Second, small-cell capacity, the average capacity of 8 tons / hour, the number of 10 tons / hour of small coal-fired boilers is 42 million units, accounting for two-thirds of the total. Third, emissions close to the ground, a great impact on quality. Fourth, boiler technology, main and auxiliary mismatch, poor health. In addition, most small boiler lack of dust removal, desulfurization and denitrification equipment, led to the current sulfur dioxide and dust emissions from boilers widespread non-compliance.
From the present point of view, domestic clean energy technology matures, the implementation of new emission standards for technology development has brought very good driving force for the future, who can stable up to standard technical requirements of the country, will have a presence in the market value Otherwise it can be eliminated.
A, WNS series automatic fuel (gas) steam boiler 1, an internal combustion boiler using a horizontal double quick return smoke wet back structure, the body-mounted using the waveform furnace, combustion chamber and back to the waveform furnace, connected to threaded pipe. After exotherm temperature flue gas flame in the furnace, carried to the threaded pipe via the folded back to the combustion chamber to the convection heat before entering the smoke chamber; high temperature flue gas enters the condenser back energy, the heat transfer by sufficiently by chimney into the atmosphere. 2, for a variety of boiler fuel oil, natural gas fuel, city gas or liquefied petroleum gas. 3, the boiler before the smoke box with movable lid cigarette, demolition, convenient rear access. Boiler with integrated burner, has started fast, high efficiency, high degree of automation features, the need to provide for a variety of local life, civil and industrial steam. 4, a boiler with full instrumentation system valve, the valve body has a boiler inlet valve, check valve, the main steam valve, safety valve, drain valve, air valve and the combustor brought solenoid valve. Water meter with a measuring point pressure display, display and control drum pressure, exhaust gas temperature display, the temperature and pressure of the burner is displayed. 5, combustion and boiler feed water using automatic control, automatic adjustment, easy operation, low labor intensity and safe and reliable protection devices, easy maintenance and repair.
How do I care after the steam boiler shutdown method Recently, many users did not know how to call maintenance shutdown after steam boilers, boiler maintenance is very simple in fact, today we explain the steam boiler and safety prices or diesel oil fired hot water boiler after shutdown maintenance. Since the cause of boiler failure or power shutdown required boiler, a steam boiler before travel should stop combustion boiler, the boiler slowly lowering the temperature until no pressure boiler, should pump before shutdown, induced draft fan and turn off the blower. After the maintenance shutdown home for boiler, furnace divided into external corrosion and home for the pot. Pot corrosion enjoying, enjoying their home for two kinds of wet and dry selected based on the length of shutdown time. When long-term disabled boiler, furnace should be paid close attention to external corrosion problems take care of themselves. First, the boiler shutdown cooling is necessary as far as possible completely eliminate fouling and ash grate heating surface of the upper, the lower portion of the furnace. Then have to adhere to certain natural ventilation flue. Under normal conditions, should be placed to dry moisture-proof agent in the furnace, flue. The dry quicklime as used, the furnace or the flue gas per cubic meter of ordinary should be placed about 3kg. After placing all the ventilation should be tightly closed doors. Lime powder to change after change. Such as boiler rooms in low-lying position, the air during shutdown severe flood tide, the method should be used regularly and placed a small fire to dry dry agent phase separation. If the boiler boiler long time, in order to thoroughly clean the soot topcoat red lead oil furnace or other metal surfaces in the anti-corrosion paint. As for the way home for corrosion inside the furnace shutdown, the shutdown Yaoan the length of time to be. Under normal circumstances, no more than one month shutdown of the available wet home for a month or more should take care of themselves dry. Dry to pay attention when enjoying the following questions: Do not dry agent in direct contact with the metal outer boiler, can be housed in a container such as an iron plate; dry agent after standing, for shutting the hole and the other hand hole cover, the vapor, the water pipe necessary to cut off valve; variant lime powder should be replaced. . Enjoying while wet, to pay attention to boiler water condensate is preferably used, followed by the available existing boiler water, demineralized water again; after adding the base, with a slow fire boiler water is heated to 80 [deg.] C the pressure rose to 100 0.2 when the 0.3MPa to maintain 2-3 hours, alkalinity boiler water circulated reach equilibrium, reduced pressure, then filled boiler water, a certain gauge, and continue to adhere to this pressure throughout the home for, alkalinity should Regular testing, decreases should be added at any time; in winter, wet enjoying pay attention to antifreeze, especially the local sewage channel and economizer; before re-use should release all the pot boiler lye, best prepared sump, in order to facilitate then. At the same time should be rinsed with clean water.
