saftey defaice pada steam boiler
It is reported that Shandong Province to further promote the action of atmospheric pollutants governance, but also to "defend the blue sky strategy" escalating, the Shandong provincial government amended the new "Regional Air Pollutant Emission Standards" and other three local standards, as the province's mandatory local standards of environmental protection, on November 1, 2019 formally implemented.
1, to improve the standard index-related emissions, can improve the level of clean production, reduce pollutant emissions, Forced out of high-emission equipment, improve air quality. The revised standard canceled the densely populated high-polluting industries sewage privilege, the use of emissions phased strategy partition; divides a region of Shandong Province as the core focus, and general control zone, different regions perform different emission limits, based on the location of the enterprise partitioning control requirements.
2, a new round of defense blue sky "Strategy" will be ultra-low emissions standards covering all coal-fired boilers in Shandong Province, and will gradually promote the non-coal industry, requires iron and steel, coking industry emissions to meet ultra-low emission standards. Key building materials industry emissions control area cement, ceramics, lime, glass, etc. are also required to achieve ultra-low emission standards, the general control zone cement, ceramics, glass and other building materials industry emission requirements more stringent than the national standards.
3, changes in air pollutant emission standards in the current round of revisions is the biggest "air pollutant emission standards iron and steel industry." The new revised standard will help eliminate a number of small-scale, backward technology, compliance governance hopeless small-scale iron and steel enterprises, and guide the existing steel enterprises discharge standards by clean energy alternatives, etc., so as to promote Shandong Province, energy, industrial restructuring, improve the quality of atmospheric environment.
4, according to monitoring data, 2018, Shandong fine particulate matter (of PM2.5), particulate matter (of PM10), sulfur dioxide (SO2), (NO2) average concentration of nitrogen dioxide fell 14.0%, 8.5%, 33.3 %, 2.7%; the number of days of heavy pollution fell for 5 days. Wherein the fine particulate matter (of PM2.5) than the average concentration of 2013, 2015 decreased 50.0%, 35.5%.
According to the "2013 Shandong Province - 2020 air pollution control plan" in 2020, the province's basic ambient air quality standards, compared with 2010 improved by 50%. Since 2013, Shandong "broken wrist" environmental pollution, has released various standard 102.
What accessories required in the use of Shandong saftey defaice pada steam boiler? No matter what kind of boiler, after a long period of use, inside the boiler will attack many chemical reactions, and according to different water quality for boilers, boiler inside the onset of chemical reactions are different, and a variety of chemical substances for a long time to accept high temperature and high humidity environment it is easy to attack many chemical reactions. This requires that we normally use in the process, and embalmed maintenance inside and outside for a long time disabled, paying close attention to the needs of the boiler furnace. Steam boiler maintenance, especially after maintenance shutdown of the boiler, it should be noted that, first of all necessary to completely remove the fouling and the upper and lower furnace grate ash heating surface in the boiler shutdown cooling, so that the smoke stick can Road has some natural ventilation. Generally the furnace in order to avoid moisture in the desiccant should be placed in the furnace and the flue. The quicklime is used as a desiccant per cubic meter flue or furnace generally should be placed about 3kg. After placing all the ventilation should be tightly closed doors. After the change of lime powder to replace the low-lying position, such as boiler room, ground flood tide during the shutdown severe cases it should be used regularly and placed a small fire to dry desiccant way combination. In the purchase of electric steam boilers, to achieve our application requirements, some equipment is very important, many customers may not know what accessories to buy, according to the Shandong steam boiler manufacturer to data for acquirers finishing introduction. Steam boiler via heat exchange device, the heat exchange of the feed water steam, heating the water, then heating, heating, toiletries, and other useful production. Soft drinks operation of the steam boiler system which needs help equipment and valves, Here we look at what the needs are, what their effects are yet valves:? 1, four safety accessories in three categories: safety, sewage valve ( valve), water level gauge (water column unit). 2, the water supply system: gate valve, check valve, safety valve, drain valve. 3, the steam system: stop valve, a ball valve (plug valve), the drain valve, safety valve, steam trap. The effect of the valve is as follows: safety valve: drain valve to avoid overpressure system: water in the discharge water level gauge or sewage system: Water Level Observation valve: off, controlling the steam trap channel: using water in a pressure discharge valve system: to avoid water supply backflow valve: flow control equipment: a processor demineralized water softening equipment, apparatus name suggests reducing water hardness, in addition to first remove water calcium and magnesium ions, that is popular water hardness reduction apparatus, the primary effect there remove calcium and magnesium ions in water, activated water, algae sterilization, Anti-fouling. 2. Pump up the loss of water will, if the level is too much loss, the amount of circulating system becomes insufficient, other adverse effects occur, it needs to fill pump system pay, usually set up a level, when the liquid is below automatic water posterior. 3. Steam reclaimer machine known steam recovery steam condensate recovery, steam condensate recovery, a condensate recovery equipment, closed condensate recovery equipment, heating steam condensate recovery system of the main unit, to recover there condensate 80 degrees, then the electricity for heating can be saved.
(5) After the above is normal, gradually open the main valve of the saftey defaice pada steam boiler for warming, generally can be sent to the sub-cylinder, and then open the emergency vent valve to discharge to the outside. At this time, the water should be replenished in time to observe the change of water level and ensure the steam pressure in the steam boiler furnace. The water supply should be based on the principle of less replenishment. Avoid excessive hydration and affect steam pressure. The steam boiler should be operated continuously for 72 hours. During the trial operation, if the equipment is checked and the water supply system is abnormal, the steam can be officially sent to the outside network and steam.
Our company got two patents on this boiler design, the flying dust internal cycling fluidized re-combustion device bosed on the high temperature separation technology; the combined design of equal flow speed for the flag type convection heating surface of corner tube boilers. We carried out independent innovative design so as to produce the high capacity energy saving chain grate boilers with advantages of reliable water cycling, efficient burning and low pollution.
