To continue to improve ambient air quality, to meet the people's growing need for beautiful ecological environment, Zaozhuang City, Shandong Province issued the latest "blue sky Zaozhuang City win the Battle of the operational plan (2018-2020 years)" (the "Program"). "Plan" put forward, built-up urban areas to carry out experimental work, to carry out large-scale coal-fired units off white wet flue gas treatment. The main objective of the "program" is that after three years of efforts, the total emissions of major air pollutants significantly reduce greenhouse gas emissions reduction synergies, significantly reduced the concentration of PM2.5, significantly reduced the number of days of heavy pollution, ambient air quality improved significantly, the people of the blue sky well-being significantly enhanced. By 2020, the city of sulfur dioxide, nitrogen oxide emissions are lower than 27% in 2015, the ozone concentration significantly increasing trend containment; of PM2.5, PM10年平均浓度分别控制在 57 mg / m, 91 [mu] g / m or less, sulfur dioxide, nitrogen oxides average concentration continued to improve air quality not less than 62%, more than the number of days of severe contamination and declining.
1, adjusting the industrial structure and layout, increase the elimination of backward production capacity and excess generated Yajian efforts; continued implementation of the regulation "scattered pollution" enterprise, and resolutely put an end to, "scattered dirt" project and has been banned "dirty scattered" Project resurgence after migration.
2, continued implementation of the total coal consumption control, by 2020, the city's total coal consumption control in less than 22.43 million tons, out of shutting down Daly environmental protection, energy consumption, safety and other 300,000 kilowatts of coal-fired units of non-compliance ; strongly promote the comprehensive improvement of coal-fired boilers, in 2018 the city built the region basically eliminated tea furnace, stove and other operating coal-fired facilities, a ban on new 35 steam tons / hour of coal-fired boilers, 65 tons of steam / hour or more coal-fired Upon completion of the boiler on the ultra-low emission, energy saving completed; low nitrogen gas boiler is substantially complete transformation.
3, vigorously promote clean energy heating, accelerate the pace of construction of natural gas to clear the system infrastructure, new natural gas for coal substitution when the priority of urban residents and winter heating, to achieve "by reducing coal gas", "coal to gas" adhere to the " gas will change. "
1, the full implementation of pollution permits management to achieve a comprehensive industrial pollution discharge standards. Accelerate the granting of emission permits, continue to promote the transformation of standard industrial pollution sources.
2, vigorously promote cleaner production. Of development zones, industrial parks, high-tech zones of concentration and control, compliance deadline conduct reform, reduce pollution industrial zone.
What safety devices have gas hot water boiler? In order to be able to make smooth combustion boiler operation of the gas hot water boiler is installed in a safe attachment of a variety of professional instrumentation and safeguards, these instruments can be a true reflection of the various states of the boiler out, and the safety device is able in a special timely warning in the case. Following on from the premium brand gas hot water boiler manufacturers to introduce common safety devices which have. 1. Gas hot water boiler safety valve has a safety device called a safety valve, its main role is to ensure that the gas hot water boiler capable of safe operation of this device with the steam pressure after the boiler during operation can be produced in limited provisions within range, can effectively prevent the boiler pressure is too high because of damage or cause a dangerous explosion. 2. The water level gauge water level alarm and we all know that gas hot water boiler needs water, hot water generated in the heat and kinetic energy to provide heat and thus play a role. Water in the boiler to be within safe limits to ensure no accidents, water level gauge is used to observe whether a suitable device, to ensure that the water level in the boiler fluctuation range does not exceed the limit. And when the water level alarm is a safety device automatically after the alarm level exceeds the range, the water level can alert fireman processing in the first time. 3. Pressure gauge boiler combustion will produce some pressure, if the pressure outside the specified range can cause an explosion hazard, so the need to install metering precise pressure gauge on the gas hot water boiler, in order to be able to pressure in the boiler fireman on at any time under observation to ensure the provision of safe working pressure of the boiler operation. In addition to the several safety devices and stable operation of the gas hot water boiler, there are many different valve also served to protect the safe operation. These devices shared with the safe operation of the gas boiler, so fireman To learn how to use the performance of the gas hot water boiler and these safety devices to ensure safe operation of the gas boiler to make hot water during operation.
Since spring, our Tai'an, Shandong, Sichuan Mianyang and other places have occurred in a boiler explosion, causing casualties and damage a large area, as well as serious adverse social impact.
(1) boiler feed water quality is not good, long run down the accumulation of a lot of scale, decreased heat transfer efficiency heating surface. Scale thermal resistance is 40 times that of steel, 1mm of scale will increase fuel consumption by 15%. Scale drum can be opened to check the situation, the exhaust gas temperature can be detected to determine whether there is fouling, if the exhaust gas temperature higher than the temperature given in the drawings, which can be caused by scaling is determined.Free Chat
